Patent DE-3042247-A1 (DE)
Title: Electrical detonator for projectile - has inertia switch controlled by airscrew to make ignition circuit active
Inventor: BUCKLEY JACK
IPC: F42C15/40
Filed: 1980-11-08
Abstract: The igniter for the projectile (1), consists of an airscrew (2), whose shaft (3) is secured in the projectile at both ends by bearings (4,5). A ring disc (6) encircling the airscrew shaft (3) is fixed in the projectile and carries a voltage source on the upper surface, e.g. battery (7), transistor (8) command circuit (9) and choke coil (10). On the underside of this disc, an induction coil is situated, acting as an exciter coil for the exciter circuit. A second ring disc (12) is connected to the shaft (3) of the airscrew (2), and has an induction coil (13), inertia switch (14) and ignition circuit. In a static position, the inertia switch (14) short circuits the ignition circuitry (15), but when the projectile is fired, the airscrew rotates opening the inertia switch (14) and making electrical contact between ignition coil and ignition circuit. This passes the firing current through the igniter pellets and sets off the projectile, in conjunction with the requisite delay mechanism (9) etc.

Title: Solvent residue removed from bulk material - by steam with partial recycling through compressor and reheater, used esp. for removing per:chloroethylene from bones
Inventor: DWORSCHAK JOSEF DIPL ING
IPC: C11B1/10
Filed: 1980-12-05
Abstract: Solvent residues are removed from a heap or bed of bulk, granular and similar solid material by means of steam as follows. A portion of the steam, contg. the stripped solvent residues from the bed, is compressed, reheated and again fed into the live steam before this enters the bed. Pref., the steam is reheated by heat exchange with a portion of the live steam. The compressor may be a mechanical compressor or an ejector. Process is used for removing solvent residues from any bed consisting of granular, bulk material. In the example shown the bed consists of bones which have been extd. to remove grease and water by means of perchlorethylene vapour. The method ensures that the solvent residues are not excessively overheated, as would occur if highly superheated steam were used; at the same time the steam does not condense again in the bed, leaving it wet. To achieve this result using steam in the conventional way, a considerably greater quantity of steam would be required.
Patent DE-3101700-A1 (DE)
Title: Photodiode
Inventor: POHLACK HUBERT PROF DR
IPC: H01L31/0376
Filed: 1981-01-21
Abstract: Photodiodes having high sensitivity for detecting and/or measuring the intensity of, preferably, monochromatic electromagnetic radiation having high pulse repetition frequencies, for example for use in optical telecommunications, in particular semiconductor diodes having at least one barrier layer in the form of a p-n or p-i-n junction. The invention relates to photodiodes having optical structures of such a type which largely eliminate those radiated power conversion pulses which occur in conventional photodiodes as a result of incomplete absorption in the barrier layer region and also the reflection losses for a given wavelength range. This is done essentially by dimensioning the optical layer thickness of the semiconductor in accordance with the patent claims and backing said optical layer in accordance with the invention with a sequence of interference layers. <IMAGE>

Title: Control unit for a room-heating system
Inventor: LOEWENHOFF PETER DIPL ING
IPC: G05D23/19
Filed: 1981-01-22
Abstract: The invention relates to a control unit for a room-heating system, by means of which the individual heating circuits of the latter can be operated individually, so that a maximum energy saving is possible. Each heating circuit is assigned a switch panel, on which a basic temperature and a further temperature value can be set. The latter can be higher or lower than the basic temperature, thus affording the possibility of different operating modes. By means of a time meter, that time can be set and predetermined in which the second temperature value is to be critical for the heating. Furthermore, an individual or joint influencing of the set duration valid for the second temperature value from a central panel is possible. The control influence coming from the central panel can take precedence over the control predeterminable by means of the individual switch panels.

Title: Heat exchanger for air/heat conducting medium and ground/heat conducting medium heat pumps, method for laying ground/heat conducting medium heat exchangers and slotted device for carrying out the method
Inventor: WERNER ALFONS ING GRAD
IPC: F24J3/08
Filed: 1982-01-25
Abstract: A specification is given of a heat exchanger produced from plastic plates and constructed, in particular, for air-heat conducting medium and ground-heat conducting medium heat exchangers for heat pumps. It has an inlet chamber and an outlet chamber as well as, assigned to these, a distributor chamber or a manifold chamber which are connected via a single opening to the inlet chamber or outlet chamber and via numerous passages to the cavity between the plastic plates. Heat exchangers of this type can be connected to one another via the outlet and inlet chambers. In a method for laying heat exchangers in the ground, the ground is slotted down to a depth of approximately 2.5 m with a width of approximately 5 cm, and the heat exchanger is then laid therein. Suitable for carrying out the method is a slotted device consisting of two separate essentially identical slotted walls (21, 22) which can be connected to one another via supporting devices, which can be guided in guide grooves (25), upon being rammed in with the aid of conventional ramming equipment. During ramming in, edge sections (23 or 24) are connected to one another like wedges at the lower end, while upon extraction of the slotted walls they can be folded into the plane of the slotted walls and can therefore be extracted in a manner passing by the heat exchangers inserted in the ground slot formed between the slotted walls. It is expedient in this case to be able to float the inserted heat exchanger into the ground slot. <IMAGE>

Title: Device for forming processable partial piles from film sheets, in particular paper sheets
Inventor: THIELMANN WALTER DIPL ING
IPC: B65H5/02
Filed: 1982-05-26
Abstract: The device has a pile lifter (H), from which small partial piles are removed by means of grippers and transferred to a conveyor (F). The conveyor (F) has a lower belt and an upper belt, between which belts the partial piles are gripped. At the feed point and at the delivery point of the conveyor there is in each case a fanning station in which the sheets of the partial pile are displaced relative to one another. In each fanning station there is a pair of rollers consisting of an upper roller and a lower roller, the circumferential speed of the upper roller being less in each case than the circumferential speed of the lower roller. At the exit of the last fanning station, air is blown between the fanned-out sheets. Adjoining the conveyor (F) is a vibrating table (R) on which the fanned-out sheets of the partial pile are collected. Due to the fanning-out of the partial piles in continuous operation and the subsequent ventilation, on the whole a relatively simple construction and rapid jogging of the pile collected on the vibrating table are obtained. <IMAGE>
