Title: Sparkling wine bottle opener - has guide arms on neck holder to guide pull levers for puller clamps
Inventor: ZERHUSEN CARL
IPC: B67B7/06
Filed: 1976-10-02
Abstract: Sparkling wine bottle opener consists of a holder for placing on the neck with a puller riding up and down inside the holder in response to a swivel lever coupled to this through a rack system. The holder consists of two parallel arms (1, 1a) carried in a common top piece (3) and with the cork puller (8) guided between them. The puller has two opposed clamps (13, 13a) to grasp the cork or stopper. The bottom ends of the arms (1, 1a) have opposing neck supports (15, 15a) and the arms are enclosed by a slide ring (14) which forces them together. Each clamp should be hinged to the bottom of the puller (8) by means of a pull lever (12, 12a) with a spring (17, 17a) between this and the associated guide arm (1). The arms should be U shaped so that the pull levers and clamps ride inside these.

Title: Contraceptive for men in form of implanted mechanical filter - is positioned in vas deferens and removes sperm from seminal fluid
Inventor: BUCALO LOUIS
IPC: A61F6/22
Filed: 1976-10-08
Abstract: The filter consists of a mass of fine granules, of a suitable size to hold back the sperm but not the whole seminal fluid. The granules are placed in a container which could hold them in either of two positions, one making the7 effective as a filter, the other not. By moving them from the one position to the other, the possibility of conception could be restored, when desired. Alternatively, the implant can include a rotary valve, by which the seminal flow could be selectively directed through the filter.

Title: Liq. tank jacket vent system - with greater heat transfer to air in safety chamber near outlet at top to generate draught
Inventor: EGLI URS
IPC: B65D90/34
Filed: 1977-04-06
Abstract: The vent is for a tank which houses a vessel containing a flammable and/or poisonous liquid, so that a safety chamber is formed between vessel and tank wall for any liquid leaking from the former. The area of the tank wall (5, 6) near the outlet port (20) allows greater heat transfer to the air in the safety chamber (18) than does that (2, 3, 9) near the inlet port (19), when heat is applied to the tank from outside, thus causing different rates of heating of the air in the chamber. This causes the hot air to rise towards the outlet, generating a draught to it from the inlet.
Patent DE-2716621-A1 (DE)
Title: Plain bearing initial lubrication system - uses larger dia. shaft section received in oil pockets on either side
Inventor: HIRT MANFRED DR
IPC: F16N7/28
Filed: 1977-04-15
Abstract: The system ensures initial lubrication of a plain bearing bush in a housing with the necessary clearance for the shaft when starting up. At the bearing position (5), the shaft (4) is of appreciably greater diameter than in adjacent sections (6, 7), and the housing (1) for the bush (2) has oil pockets on both sides (12, 13) of the latter, extending upwards at least to the underside of the adjacent shaft sections. In normal running, the oil delivered to the bush by a pump, and emerging between it and the shaft, is partly accumulated by the pockets. Thus oil reservoirs are formed whose oil level is above the lower edge of the larger diameter shaft section (5), so that this is always immersed in oil when stationary and on starting up.

Intermediates (III) (which are stated to be new) are stable, easily purified crystalline cpds., giving high-purity prods. (I).
Patent DE-2732632-A1 (DE)
Inventor: HUMMEL JAN ING
IPC: H04L1/18
Filed: 1977-07-19
Abstract: An information transmission arrangement with two stations (A, B) in each case has a telegram transmitter (TS) and a telegram receiver (E). The telegram transmitter (TS) of each station is connected to the telegram receiver of the distant station in each case via a dedicated transmission link (Ü1, Ü2). Furthermore, an acknowledgement transmitter (QS) is provided in each station (A, B) which, on receiving a telegram, is able to return an acknowledgement signal to the station transmitting the telegram provided that its own telegram transmitter (TS) is not transmitting a telegram at that moment. Following transmission of a telegram, the respective transmitting station expects to receive the acknowledgement signal from the distant station within a short period (acknowledgement window), incoming telegrams shifting the acknowledgment window to the end of that telegram. Each of the telegram transmitters (TS) is blocked for the duration of the acknowledgement window or for the duration of the transmission of an acknowledgement signal by its own acknowledgement transmitter (QS). <IMAGE>

Title: Flow control of forced circulation boiler flame tubes - remixes parallel flows from different dia. tubes in proportions to control temp.
Inventor: BOEDER WILFRIED
IPC: F22B7/12
Filed: 1978-06-14
Abstract: The arrangement concerns the flow of combustion gases from the combustion chamber (3) through a boiler (1) whereby the gases give up their heat to a heat transfer medium whilst passing through cooling zones (7, 8, 10) to a flue duct (11). The gases are split in at least two flows (7, 8) with differential heat transfer to the medium, after which they are at least partly combined again into a single flow whose temp. can be selected, and then led to a point of utilisation (16). The proportion which does not reach this point is led to the flue via the last cooling zone (10). The temp. of the mixed flows (7, 8) is controlled (12) by controlling their relative proportions.

Title: Beverage-filled container compactor for contents recovery - has hydraulic cylinder-operated compacting ram working together with reciprocating gate
Inventor: HUSMANN GERHARD
IPC: B30B9/06
Filed: 1978-09-21
Abstract: The equipment for the destruction and compacting of beverage cans past the selling date provides the separation of the contents from the sheet material so that they can be used for animal food preparation. The cylinder carries a compacting ram, is reciprocated by an hydraulic cylinder. The cans are fed into the machine through a hopper and after passing cutting edges drop into the compacting chamber. When the ram moves into the compacting chamber, the beverage-filled cans are burst open partly by the compacting pressure and partly by getting caught on the cutting edges and the fluid escapes through perforations into a drain connection. During this operation a gate is in the lowered position, acting as an abutment for the compacting operation.
