A method of controlling the entry and removal of characters from a recirculating buffer store is described. The buffer store has a plurality of data storage channels within which the respective bits or elements of a character entered into the store are circulated, and an index bit of the same given polarity is entered into an index storage channel each time a character is entered in the store. The method further comprises recirculating the bits in the index channel in synchronism with the bits i...

A central buffer coupling for rail vehicles having a series connected buffer gear includes a pivot pin which is supported on a rail vehicle in a vertical position. A coupling head including a buffer gear has a connecting arm, which is universally supported on the pivot pin for vertical and horizontal deflection. A support arm of U-shaped configuration is carried at the lower end of the pivot pin and a leaf spring has one end connected to the support arm end and an opposite end connected to the c...

An image transmission system. A television camera scans a projected image and generates a video signal. An input circuit converts the video signal into a two-level signal which is sampled and stored digitally on a magnetic disk or drum. After the signals are stored, they are used to reconstruct a video signal by being recombined and combined with blanking, horizontal drive and synchronization signals from the television camera. All timing is controlled by signals recorded on timing tracks on the...

In a data processing system allocation of excessive main/working storage space to sequential input records (input blocks) of indeterminate length frequently results in wasteful fragmentation. This is avoided by the present invention. An input-output channel of conventional construction is modified so that in chaining mode it (the channel) can operate optionally to: (1) transfer sequential input data blocks of unspecified length into contiguous positions in main storage, and (2) without CPU inter...

A buffer for a vehicle comprising a fixing member inserted between a cab or rear body and a chassis frame, and a buffer means held on the member to contact with either of the cab or body or the frame. The fixing member is tilted to deform the buffer means to absorb energy when the cab or body moves relatively to the frame upon collision.

A data buffer makes use of a plurality of buffer storage cells into which serial bit streams are sequentially written, in order to obtain correction for phase jitter. A write clock signal is derived from the serial bit stream and is used to sequentially write the digits into the cells. A stable clock source is used to provide the basic timing for sequentially reading the bits out from the buffer storage cells, and a logic circuit is used in conjunction therewith to obtain the retimed serial bit ...

A buffer conveyor system is employed to interface a package filler machine having a substantially constant demand or fixed input requirement with a commodity batch weigher/checkweigher having a variable output potentially in excess of the fixed input, but subject to rejects. The system includes novelly designed commodity transport buckets, which are transported by conveyors along a closed loop path through the batch weigher/checkweigher, a filled bucket buffer or holding station and the package ...

An oil buffer in which a tapered control rod is provided in a cylinder and an oil injection hole through which said control rod passes is provided at the bottom of a plunger slidable in said cylinder so that oil in the cylinder will be injected into said plunger to produce a buffer action, and further characterized in that an oil check is provided at the top in the inside of said plunger, said oil check being positioned above said oil injection hole so as to force back downwardly the oil injecte...

This invention describes an apparatus which uses a vacuum buffer to control the position of a magnetic tape against the transducing heads whereby the tape can be lifted away from the head surface during rewind. The vacuum buffer comprises an enclosed space on the front of the tape deck which is enclosed by two rotating cylindrical elements, the tape stretched across the top of the elements and a wall closing the space on the bottom side, between the two rotating elements. One or both of the rota...

A single up/down counter controls a first-in/first-out shift register type buffer. Each buffer shift stage has a read-out gate selectively activated by the counter. The counter counts up one for each data input, while the shift register simultaneously shifts all data signals one shift stage. For read-out, the counter is decremented, while no action is taken on the shift register. Simultaneous input and read-out does not affect the counter while the shift register shifts its signal content by one...
