Title: Breech block drum with open propellant chambers - has chamber edge seals against yoke for firing caseless ammunition
Inventor: SACKENREUTER HANS DIPL ING
IPC: F41A3/74
Filed: 1970-03-28
Abstract: The breech block has laterally open propellant charge chamber which is closed after loading for firing by a closing yoke. This arrangement is used for firing caseless ammunition.

Patent DE-2226060-A1 (DE)
Title: Effect textured thermoplastic yarn -lengthwise - variation of degree of heat set twist gives variable bulk
IPC: D02G1/02
Filed: 1972-05-29
Abstract: An effect yarn is produced by false twist crimping a thermoplastic yarn and varying the degree of heat set twist to give variable bulk along the length of the yarn. Production of variable bulk nylon etc. yarn. In a friction false twisting process in which the twist level is varied in the heating zone, yarn (1) is fed by input feed roller (2) to heater (3) where it is raised to the twist setting temperature. Then the yarn cools to below its second order transition temperature, preferably at least 20 degrees C below, before it encounters a twist snubbing device (4) comprising fixedly located, free running rollers (5,6) and a yarn guide (7) which can be reciprocated. From there, the yarn (1) passes to a friction false twister (8) having a ring-like friction bush (9) rotating on an axis (10), through which the yarn (1) is withdrawn via a guide (11), a wound up at (12). The snubbing yarn guide (7) is reciprocable between the rolling-bearing supported rollers (5,6) in a slot (19) in the base plate (14) and the varying twist level in the heating zone caused by such reciprocations gives rise to a bulk variation lengthwise of the yarn. An alternative twist snubber comprises a rod (24) pivoted at (25) and swingable (arrow 26) to alter the bending angle of the yarn and hence the pressure of the yarn (1) against the end of the rod (24).

Title: Programmable knitting frame needle selector - uses optical pattern sensor and needle spacing sensor for needle electromagnet actuation
IPC: D04B7/08
Filed: 1973-07-07
Abstract: In an automated hand knitting frame, a carriage with an optional sensor for the knitting pattern sheet also contains two data storage turrets for setting the needles. A second sensor scans the marks of the needle spacing and passes the signals through a threshold circuit and a monostable multivibrator to a flip-flop. The pattern scanning pulses are applied to the latter via a threshold switch. An amplifier can then actuate the electromagnets of the turrets for the needles. This method causes less wear on the pattern sheets than a mechanical scanning of the perforations. The user can design her own pattery by filling in black pencil marks into the squares of a pattern sheet.

Title: Vacuum mixer for clays or putty - discharges to atmosphere through alternate vacuum locks to reduce cycle time
Inventor: SCHMIDT HANS-JOACHIM
IPC: B01F15/02
Filed: 1973-07-30
Abstract: An appts. for kneading and/or mixing plastic materials such as putty, clays, porcelain, adhesives etc. operates under vacuum and has an extraction device comprising a screw for discharging the material after mixing. The outlet from this extraction device can be alternatively connected to one of two vacuum intermediate chambers which, in turn, can be alternately connected to the final discharge outlet for the material. Pref. the communication paths between these four openings are provided by a four-way valve, which can connect the outlet of the said extraction device alternatively to one or the other of two piston-cylinder units; the material is thus discharged into a cylinder where the piston withdraws maintg. the material under vacuum; the four-way valve is then switched over, bringing the extraction device outlet into communication with the opposite cylinder, while the already filled cylinder is brought into communication with the final outlet, so that advancing of the piston discharges the material to the atmosphere. This gives a considerably reduction in the overalll cycle time, as a result of a decrease in the considerable delay of discharging a vacuum chamber against atmospheric pressure.

The other end of the lever rests on a piston within an oil filled cylinder, fitted with a nonreturn valve. The adjusting cylinder holds the piston in the diagram which supports the spherical head which rests in the spherical socket at the free end of the lever. A circular spring is held in a circular groove in the piston. The end of this spring is bent upwards and it fits into a slit of the rocking lever. This arrangement ensures that the piston cannot rotate relative to the rocking arm. A longitudinal slot in the piston is in contact with a circumferential groove.
