Title: T-junction for rubber hose with fabric reinforcing inlay - with funnel-shaped pipe section joined by vulcanisation
Inventor: KURZOK RAIMUND
IPC: F16L31/02
Filed: 1975-11-15
Abstract: T-junction for rubber hose with fabric reinforcing inlay comprises an opening in the wall of the hose, of which the edges are joined to a second inserted hose by vulcanisation and the joint zone between the two hoses is lined by a funnel-shaped rubber hose section which is attached by vulcanisation. The inlay comprises, in the region of the opening in the wall of the main hose, a longitudinally extending gap between the threads, with a width comprising approx. half the inside dia. of the hose. The gap allows expansion of the threads without tearing them in a narrow longitudinal zone of the hose, allowing an opening to be formed in the hose wall without tearing or removing the threads. The gap does not affect the strength of the hose.

Title: Displaying of values of analogue signals - is for LF level with four channels in quadrophonic amplifier
Inventor: KLANK OTTO
IPC: G01R13/40
Filed: 1975-11-22
Abstract: The device comprises an analogue-digital convertor (9) allocated to the display elements and able to evaluate only one of the signals. A multiplexer (10) consecutively controls the four display elements by the time division multiplex method in accordance with signals from the A/D convertor (9). This is done so quickly that an impression is produced of simultaneous parallel display. In the quadrophonic system the signals from each of four amplifiers (1-4) pass through threshold level rectifiers (5-6). The four display elements (11-14) are typically light emitting diodes. The pulse circuit arrangement includes a ring counter.
Patent DE-2554115-A1 (DE)
Title: Double pistoned IC engine - has cam operated regulator piston to assist gas exchange
Inventor: ABOU-KAMAL SAMY DIPL ING
IPC: F02B75/28
Filed: 1975-12-02
Abstract: The double piston enables a working stroke to be performed at each crankshaft revolution. The regulator piston (6) is actuated by an over head cam (1) and rocker gear (3) to allow the regulator piston to return faster than the main piston (10). The gas exchange is regulated by a chain driven rotary valve (12) whose port is respectively covered and closed by the main piston movements. The regulator piston returns faster than the main piston after the main piston has uncovered the intake port to remain at the piston seat (19), in the cylinder head during the compression and working strokes. The regulator piston is timed by the cam lobe to move towards the main piston to assist in the expulsion of the exhaust gases. The regulator piston is returned by a closing spring (5).
Patent DE-2556999-A1 (DE)
Title: Pesticides distributed through stacked produce - in pref. gastight container by cans opened remotely by light pressure
Inventor: SPEETZEN JOACHIM DR
IPC: A01M17/00
Filed: 1975-12-18
Abstract: Pests are destroyed in stored goods and the space in which the goods are stored is disinfected. The goods are stored in a closed space, e.g. formed of a gastight covering sheet or plastic sheet, and a predetermined number of containers, each containing a pest-destroying gas or liquefied gas, are distributed over the pile of goods at specific locations. Each container is placed on a container-opening device and then all the containers in succession are pierced or opened by light pressure; this causes the contents to escape, evaporate, and cool and gradually propagate throughout the stacko of stored goods. The gas thus produced may be subjected to forced circulation. Used for all kinds of stored agricultural produce, partic for produced being transported in railway wagons etc. The method enables highly toxi pest-destroying agents to be very much restricted in their use, with no riks of their affecting the person concerned with disinfecting the goods. It is possible for all the containers to be opened by simply pressing down onto each in turn, and there is no need for the operator to wear a gas mask during this operation, since the liquefied gas escapes only slowly and in any case is contained within the covering sheet.

Title: Rapid slag removal from molten iron or steel in ladle - using scrubbing gas, synthetic slag powder, and a scraper
Inventor: HAUSEN PETER DIPL ING
IPC: C21C1/00
Filed: 1975-12-19
Abstract: Scrubbing gas acts on the surface of the bath on the raised side of the vessel so the slag is swept towards the lower side and in front of the scraper. The gas is pref. bubbled through the melt via an injection brick in the vessel or a lance. A powder with compsn. 70-85% SiO2, 10-18% Al2O3, 3-8% K2O and 2-6% Na2O is pref. added to the surface of the bath during the deslagging operation. Used e.g. in ladle desulphurisation of crude iron or steel. As compared with conventional methods, more slag is removed in less time.

Title: Economical HF diode demodulator - operates at very small HF voltages in order of demodulating diode's diffusion voltage
Inventor: WILLER WALTER ING
IPC: H03D1/10
Filed: 1976-05-31
Abstract: The HF demodulator demodulates very small h.f. voltages of the order of the diffusion voltage of the diode employed. This is achieved by establishing a radiation coupling between teh demodulating signal and the HF input signal. This coupling may be thermal or optical. If thermal, then the demodulating diode in the HF circuit is controlled by a variable heating element (RH). If optical, then the demodulating diode is controlled from a variable light source (S). The demodulating diode is in both cases connected into an LCR circuit.

Title: Hydraulic receiver charging valve - has valve seat formed in piston moving between stops to form spring loaded stop valve
Inventor: BELART JUAN
IPC: F16K31/363
Filed: 1976-06-03
Abstract: The receiver charging valve has a pressure union connected to the receiver and via a stop valve to a return union. The stop valve has a plug spring loaded shut, also thrust into the shut position by the pressure at the pressure union. A control piston actuated by the pressure in the receiver acts on the plug in opposition to the spring. The valve seat is formed in a piston moving between two stops. When the stop valve is shut, piston and plug are hydraulically locked together. A spring of less strength than the hydraulic locking force acts in opposition to it between piston and plug.

The sheaths are pref. removable. The corners pref. have a radius of several times the metal thickness. Used to enable close packing of fuel elements with neutron - absorbing material between them, thus achieving economical storage over long periods. The arrangement provides a simple and economical sheath for each element with the minimum of construction cost.

Abstract: The unit evacuates heat from individual units containing heat generating components, mounted above each other and provided on opposite sides with holes for air circulation. they are supplied with cooling air from a common fan applied vertically to one side of the column, and vertically evacuated from the column other side. An air channel (23, 24) limited on its sides by adjacent equipment columns (A-C) has a slanting partition (29, 30) which separates air flowing out from one column from the air flowing into another column, so that cross-section of the inlet channel decreases in the flow direction, while that of the outlet channel increases. Ends of these partitions are movable, and movable plates (35, 36) are provided at two sides of equipment units, by which the volume of cooling air flowing through it is controlled.

Title: Security alarm for roller blinds - has moving electric contact on operating tape that passes over fixed contacts to trigger alarm
Inventor: JAHN GEB TIEDEMANN INGEBORG
IPC: G08B13/08
Filed: 1976-09-08
Abstract: A security alarm for roller blind units is triggered by attempts to raise the blind. The roller blind is raised and lowered by pulling on a tensioned tape loop (3) that passes the blind housing (6). Electrical contacts blocks (1) are located beneath the tape and soldered conductors are coupled to an alarm circuit. The circuit across the contact blocks is completed by a metal foil pad (2), suitably positioned on the tape. When the blind is in the secured position the circuit open. Any attempt to raise the blind causes the foil to pass across the contact blocks and the alarm is triggered.
