Patent DE-2701627-A1 (DE)
Title: Breast prosthesis comprising cup-shaped silicone rubber bodies - sealed into plastics film, made by fixing two seam-welded films in mould, pressure-filling the resulting envelope and vulcanising
Inventor: RECHENBERG CORNELIUS
IPC: A61F2/52
Filed: 1977-01-17
Abstract: Mfr. of (female) breast prostheses from suitably cup-shaped bodies, welded into plastics film, and made of addn, - crosslinkable 2-component silicone rubber, is claimed. Two flat films forming the envelope for the prosthesis are welded together along the intended edge of the prosthesis, leaving a filling opening, and are fixed, along the weld seam, upon the edge of a mould cavity. The mould is closed by a cover which corresponds with that portion facing the mould cavity, to the intended configuration of the rear of the prosthesis. A 2-component, silicone rubber, moulding cpd. is forced, under pressure, through the opening left between the 2-welded-together films until they are pressed against the walls of the mould cavity. The moulding cpd. is then vulcanised, in the mould, at 100-150 degrees C, and the opening of the envelope sealed off. The resulting prosthesis is free of undesirable bubbles and voids. Welding seams are clean, without risk of moulding cpd. oozing from the envelope during moulding/vulcanising.

Title: Drinking water protection supply pipe divider - has valve opening load release duct at low pressure, with spring and piston
Inventor: WALETZKO ALFRED
IPC: E03C1/10

Title: Spring for heavy loads - generates compression loads in spider and smaller ring and tension in larger one
Inventor: ROEHRS GUENTER DIPL ING
IPC: F16F1/32
Filed: 1978-05-24
Abstract: The spring absorbs and emits large forces, comprising two annular bodies of different diameters joined by a compression spider. Forces acting in the axial direction of the ring generate in the spider itself (2) and the small ring (1) compression loads and in the large ring (3, 5) tension loads. As the result of elastic length alterations of the individual components these produce spring action in the axial direction. Instead of a single thick spider there can be several correspondingly thinner ones. The dimensions of the annular bodies can be such as to limit the amount of spring movement by contact with each other.

A parallel line (23) from the bottom of the central section (5) forms a circuit with an inlet line (22) at the top. Both these flows are controlled by a three way valve (9) for the inlet line (22) and the outlet (04) at the top.
Patent DE-2828733-A1 (DE)
Inventor: GUZMAN-EDERY JORGE DIPL ING
IPC: H04Q9/14
Filed: 1978-06-30
Abstract: In telecontrol systems with multipoint traffic, the information items spontaneously occurring in a plurality of remote terminal units are activated by general call (A) and then transmitted to the central station staggered in time without overlap in a number of successive intervals, corresponding to the number of remote terminal units, of equal length in the form of messages. With a relatively rare occurrence of spontaneous information items, this means a great loss of time in the transmission. The problem solution provides for transmission of the spontaneous information items from each remote terminal unit with m-fold identical repetition of the relevant message within a frame of n successive intervals (a ... f) in each case allocated to one message corresponding to an m-of-n code after a general call (A), the number of combinations of n elements to the mth class (m over n) corresponding to the number of remote terminal stations (20). <IMAGE>

Title: Bag-type dust filter for mines - with flap valve closing one of two chambers briefly for back flushing
Inventor: HOELTER HEINZ
IPC: B01D46/00
Filed: 1978-07-06
Abstract: In a bag-type filter, esp. for use in belt conveyor transfer stations of underground mines, both the dust-laden air space are divided by partitions into parallel ducts. Between the filter and the suction fan, a flap valve continues the partition but can be moved from a neutral position, where both ducts are open to positions on either side where one of the ducts is temporarily shut off. During this side position, backflushing tubes in the clean air space are operated in short bursts to clean the adhering dust from the filter bags. Actions can be automated as a function of the pressure drop across the filter. This results in a low-cost filter which never has to be cut off.
