Patent DE-2519484-A1 (DE)
Title: Non-crush roof covering with non-inflammable insulating layer - without intermediate bonding layer for fibres of insulating layer
Inventor: IHLEFELD KARL-HELMUT
IPC: E04D5/10
Filed: 1975-05-02
Abstract: Rollable web of roof covering material is bonded to an insulating layer of mineral fibre strips in which the fibres extend perpendicularly to the covering web (1). The latter consists of thermoplastic material or is coated with it on the side adjacent to the insulating layer (2), and the bond between them is formed by passing the covering web beneath a heater to melt its surface to a low-viscosity state, then pressing the insulating layer into the viscous layer and holding it there until the viscous layer has cooled and hardened. Pressing is carried out by a twin belt assembly of which the lower belt is guided over a table-like hollow box through which coolant flows.

Title: Stacked set of compressed tablets for preparing instant beverages - comprises bonded together, but easily separable, components for adjusting the compsn. of the intended drink
Inventor: SCHOONMAN MARTEN LEONARD
IPC: B65D65/46
Filed: 1975-05-27
Abstract: A combination of ingredients for the prepn. of instant beverages from water-soluble, edible, matls. and a measured amt. of water, is composed of a portion of a 1st ingredient, e.g. powdered coffee or tea, and >=1 othe r2nd ingredient, e.g. sugar or milk powder. Each edible matl. is in form of a compressed tablet. All tablets are bonded together face-to-face tof orm a stack, but the component tablets can be easily sepd. from one another before immersion into the water so that the compsn. of the intended beverage may be controlled as desired. The tablet may be informed of circular discs with bevelled edges. This enables the water to reach a relatively large surface of the tablet stack. The tablets are glued together in their central zones inside the bevelled edges. The stack may be enveloped in a hot-glued, water-soluble skin e.g. of transparent PVA. The envelope also serves to protect the tablets and prevent their premature disintegration.

Title: Frequency multiplexed sensor loop - use passive LC filters as failure detectors that are tuned to specific transmitter signal frequency
Inventor: DECK WERNER
IPC: H04B3/56
Filed: 1975-09-13
Abstract: A frequency multiplexed sensor arrangement allows a single cable passive loop to be used for indicating service faults in operational equipment e.g. rail transport systems. A central control unit has a number of frequency generators (1, 2) coupled over a signel lien to sensor units (3, 4). The sensor units are coupled in series and are looped back to the controller with a number of receivers (5, 6) that are tuned to different frequencies. Each sensor unit has a normally closed relay (3, 1) and an LC filter (3, 2). In the event of a failure in a specific unit, the relay opens and signals are transmitted over the filter. All signals are transmitted except for the timed frequency.

Title: PAM-PCM nd PCM-PAM conversion - has PAM-PCM counter switched to PCM-PAM state when signal bit trains indicates ready state subscriber unit
Inventor: WINTZER KLAUS
IPC: H03M1/00
Filed: 1975-09-30
Abstract: The convertor has an analogue-digital counter which is actuated from an initial counting state determined for the immediate control of conversion from digital to analogue and for the further conversion from analogue to digital. In the case where a train of predetermined call signal fits is sent to an input register when a subscriber's unit is in a state ready for receiving and transmitting analogue signals, the counter is set for digital-analogue conversion. The counter is reset to its initial position at the moment when its associated subscriber unit is in its rest state.

Title: Switch gear mounting assembly - can be removed by single engineer simply and without danger by pivoting through front of cabinet
Inventor: KOERBER RUDOLF DIPL ING
IPC: H02B11/00
Filed: 1975-10-08

Title: Return to zero circuit for signal regeneraton - uses four coupled transistor stage to scan input and generate fixed pulse if threshold valve is exceeded
Inventor: BOEDEKER FRIEDRICH ING GRAD
IPC: H04L25/24
Filed: 1975-10-28
Abstract: A return to zero circuit for signal regeneration uses four coupled transistor stages to allow operation over a wide range of frequencies with low power consumption. The outputs of two transistor stages (T2, T4) are connected to a common time to generate an output (Q) and to provide interconnection with two other transistorr stages (T1, T3). The input signal (D) is periodically scanned at the same frequency as the applied clock signal (T) and if the amplitude during this period is higher than a threshold value, then an output (Q) is generated. Immediately following the clock signal going low, if the input is above the threshold, then two transistors (T1, T3) conduct and two (T2, T4) are inhibited. A '1' level is therefore generated on the output line (Q).

The stepwise operated drive roller swivels the inking roller with its arm so far that the inking roller contacts the ink supply roller (39) whereby ink transfer is effected by mutual rotation. The arm is returned to its initial position by a spring (31).

Title: Adjustable shelf divider system with guide plates - have parallel grooves for side or top mounting of dividers
Inventor: STROBL KARL
IPC: A47B57/58
Filed: 1976-01-02
Abstract: The adjustable shelf divider system comprises guide plates (1) which can form the side walls and are designed with parallel grooves (2) which are cut in to have a T-shape profile so that the correspondingly shaped insert ends (6) of shelf or support elements (5) can be fitted in. In this way, these shelf elements can only be inserted from the end so that they cannot fall out nor require an essential support on the other side. Where horizontal shelving is to be divided up widthways the guide plates are preferably mounted at the top with the grooves (2) facing downwards so that the shelf dividers (5) can hang down.

Title: Sand paper for bird cage - is made of sand stuck onto normal or absorbent paper which can be easily removed from cage for cleaning
Inventor: LUDWIG LOTHAR
IPC: A01K1/015
Filed: 1976-01-08
Abstract: The birdcage floor cover sheet is made of a thin layer of sand stuck to a sheet of paper which can be ordinary paper or absorbent paper. Absorbent paper absorbs droppings and dries them out without leaving an odour. The sand stuck to the paper does not spill out onto the floor of the room in which the bird cage stands, nor does it drop onto the cage floor or the floor of the cupboard. The birds themselves do not have sand sticking to them or to their feathers. The birds are in less danger of becoming disease-ridden, and the cage is quickly and hygienically cleaned.
Patent DE-2604903-A1 (DE)
Title: Timing system for closed circuit hydrogen injection - has rotary injector pump whose cam ring is displaced by engine speed dependant pressure
Inventor: HIERETH HERMANN DIPL ING
IPC: F02B43/10
Filed: 1976-02-07
Abstract: The closed circuit injection system consists of a rotary distributor pump turned by the engine. The hydraulic medium is contained in a small reservoir and is pumped to each injector in engine firing order and returned to the reservoir. The injector timing is varied according to engine speed by a compensator piston (22) sliding inside a compensator housing (23) and tensioned against the hydraulic pressure by a spring. The piston is connected by a push rod to the cam rim (34). Increased fluid pressure resulting from an increase in engine speed overcomes the spring pressure to advance the injection timing.

Title: Meat recovery from bones - by two press operations, emulsification and centrifuging
Inventor: NEUHAEUSER SIEGFRIED DIPL ING
IPC: A22C17/04
Filed: 1976-07-06
Abstract: Meat adhering to bones is recovered by a second press operation at a higher pressure after a first press operation has removed a large portion of meat with a max. bone fines content of 0.8 wt. %. The meat produced in the second operation is mixed with ice and salt, emulsified and sepd. by centrifuging into a solids phase, contg. bone fines and connective tissue, and a liq. phase, contg. albumin, fat, water and salt. Emulsification of the fat before the centrifuging operation ensures that the centrifuge does not become clogged. The process combines a high percentage recovery of meat with a very low bones fines content in it.
