There is disclosed a safety closure cap for use with a bottle or other container having a neck portion. The closure cap is made of an elastically deformable or expandable synthetic plastic material. The neck portion of the bottle has on its outside a ring-shaped rib flattened at a portion of its circumference. The inside of the skirt of the cap has thereon several radially inwardly protruding lugs. These lugs can be forced to pass the rib on the neck portion in any angular position of the cap re...

There is disclosed a device for lapping an unlimited number of balls in continuous operation. The device has a stationary working disc and two rotary working discs which are driven in opposite direction and at differential speeds. The rotary discs and the stationary disc define therebetween a working gap into which balls to be lapped are continuously fed and from which they are discharged after having passed through all or part of the gap. Driving of the rotary discs in opposite direction and at...

A rotatable assembly is rotatably mounted on a stationary assembly. The stationary assembly guides a conductor wire, or the like, to a wrapping station, the rotatable assembly applying glue or other adhesive to a portion of a wrapping tape which is wrapped around the conductor wire at the wrapping station. The glue is applied to the wrapping tape by supplying it to a receptacle in the rotatable assembly, from which it is forced out through a hole by centrifugal force. The receptacle is of conica...

There is disclosed a typewriter using a single element print head wherein the tilt and rotate positions for character selection are obtained by servo systems driving tilt and rotate shafts. The system utilizes a digital multiplexing system whereby common elements in the servo channels are time shared. One common element is a binary arithmetic unit which compares binarily represented actual and desired position values of the shafts to fetch from a memory desired velocity information. The fetched ...

The present invention relates to a frequency modulated oscillator, preferably operating within the microwave range, comprising a resonator having a reversed biased semi-conductor element, for example, a Gunn diode and voltage dependent capacitor, for example a varactor diode acting as a frequency modulator and being connected to a modulating signal source. In order to linearize the modulation characteristic, there is a resonant circuit in the resonator which circuit is tuned to the first harmoni...

A printer has a horizontal platen for supporting paper and a print head which moves horizontally opposite thereto during indexing operations and is driven toward the platen for character printing. The print head is mounted on a carriage bearing block acting as a linear bearing and having a passageway of complex cross-section resulting from the superimposition of a square and a circle. A controllably rotatable carriage shaft passes through the passageway of the block.

There is disclosed a device for cutting a fishing line by pulling the same sharply against cutting edges on the device. The device also provides a flap including an opening for hooking a fish hook tied to the line thereby preventing flapping of the line when the rod is not in use.

A SPC-telecommunication system comprises test points, operating points, data-bus interconnected data storage registers, a phase generator and an access signal generator. The registers include instruction registers for storage of instructions, and an unit-incrementing address register for storage of addresses identifying the instructions. The phase generator produces phase signals by which the processing cycles of the instructions are divided in phases. The access signal generator is controlled b...

An antenna for transmission of microwave energy, has a plate with openings for receiving energy from a feeding or input waveguide connected to an energy source and for feeding the received energy to a number of antenna or output waveguides provided with one or several openings through which energy from the feeding waveguide is to be emitted. The plate on the input side is provided with tracks in which a part of the feeding waveguide, which part together with the plate forms the feeding waveguide...

In a system for recording bits in elements along a moving magnetic medium wherein a first valued bit is represented by a pulse of a first width, length or duration, and a second valued bit is represented by a pulse of a second width, length or duration, there is included the improvement of changing either the first width or said second width when the bit to be recorded and the bit previously recorded have the same value.
