Title: Switch operated alarm circuit - includes two current flow control devices responsive to position of reed switches to activate horn alarm
Inventor: DUKE NORMAN GEORGE
IPC: G08B13/08
Filed: 1978-10-18
Abstract: The burglar alarm has a series of switches located close to each other which are responsive to the application of a magnetic field. One of the switches terminates current flow to a sentinel current device while the others initiate current flow. The sentinel current device operates to supply voltage for an alarm circuit when it conducts only. Thus, in order to render the device ineffective, one must know how to apply a magnetic field to the terminating switch only without activating any of the switches that initiate current flow. The switches are all located close together so that special knowledge is required to cut off supply voltage to the alarm circuit.

Title: Diesel engine fuel injection system - has sleeve with rounded top and offset hole inside precombustion chamber under injection valve
Inventor: GRUPP EBERHARD
IPC: F02B19/14
Filed: 1978-11-30
Abstract: The diesel engine with a precombustion chamber (5) and a main combustion chamber (4) has a fuel injection system with an injection valve (7) bin line with the channel connecting the chambers. A heater plug (8) projects sideways horizontally into the precombustion chamber. This channel (9) is formed by a sleeve enclosing the precombustion chamber, and with outlet holes (10) at the bottom, discharging sideways into the main chamber, above the piston (3).

Title: Stable hardener soln. for photographic gelatin emulsions - contg. water soluble salt of 2,4-di:chloro-6-hydroxy-1,3,5-triazine and an alkali metal borate
Inventor: KOBAYASHI TERUO
IPC: C07D251/26
Filed: 1979-03-19
Abstract: Aq. hardener soln. for proteinaceous material, esp. photographic gelatin emulsion, contain (a) a water soluble salt of 2,4-dichloro-6-hydroxy-1,3,5-triazine (I) (b) 0.02-0.2 moles (per mole (I) of an alkali metal borate such as xMo2.yB2O3.zH2O where M is Na, K or NH4, z is 0 or whole number and x and y are 1 or 2, and opt. (c) an inert water-soluble solvent such as acetone or dioxan. The (I) can be made in practically quantitative yield from cyanuric chloride (II) in aq. medium, so that expensive solvent recovery is not required. The amt. of alkali metal borate required is considerably less than in DT 2820108, so that waste water from the hardening process is less polluted. The hardener solns. have improved stability compared with prior art materials of this type, and partic. do not form CO2 due to hydrolysis, so that problems of bubble formation during use and the danger of pressure build up in containers during storage are eliminated. The solns. are esp. useful for hardening photographic gelatin layers. No fogging or loss of sensitivity occurs and the abrasion resistance of the hardened material is increased considerably.

Title: Coordinated positioning of coke oven machines - by absolute positioning of pusher-leveller and relative positioning of others
Inventor: TESCHNER WOLFGANG DIPL ING
IPC: C10B41/00
Filed: 1979-03-21
Abstract: Parent patent described a positioning system for the coordination of all operating machines on a coke oven battery. It is now suggested to equip only the coke pushing and levelling machine with an absolute positioner. The positioning of the other machines is effected either by a relative system based on sensor scanning of marks or by storing the next location in the machine which uses range radar to find it. Arrangement results in a simplification of the decentralised co-ordination of all functions of the coke oven battery machines.

Patent DE-2921163-A1 (DE)
Inventor: REICHMANN WOLFGANG DR
IPC: C08L75/12
Filed: 1979-05-25
Abstract: The disclosed invention is concerned with porous substrates impregnated with moisture curing polyurethane oligomers incorporating tertiary nitrogen atoms and free aromatic isocyanate groups in which the yellowing tendency of these isocyanates is diminished or supressed by the inclusion of specific light protection agents. These agents are either substituted oxalanilides or indole or indoline derivatives. The impregnated substrates cure rapidly when exposed to moisture to yield rigid structures suitable as a replacement for Plaster of Pairs in medicinal and veterinary bandaging applications.

Title: Sawtooth waveform generator in control circuit - is for air conditioning compressor, using pulse width regulation with operational amplifier as voltage follower and capacitor
Inventor: STEINMANN HELMUT ING GRAD
IPC: H03K4/501
Filed: 1979-09-29
Abstract: The sawtooth waveform generator is used to control the air conditioning compressor of the air conditioning system of a motor vehicle using pulse width control. It has an operational amplifier connected to a direct voltage supply and functioning as a voltage follower. The positive input of the amplifier is connected to the junction point of an R C network. The negative input is linked to the output in the form of a voltage follower. The charging voltage of the capacitor (C) is kept to a practically constant value by switching to a constant voltage source (V). The constant voltage source is formed by a diode (D) which is connected between the output of the operational amplifier and the voltage supply (UB,IC2) via a resistor (R7).

Title: Monitor for feed water pipe of dish washer and washing machines - has two electromagnetic valves in line controlled by sensors which detect loose or burst pipes and/or water level
Inventor: HEISSMEIER WALTER DIPL PHYS
IPC: D06F39/08
Filed: 1979-10-12
Abstract: The dish washing machine is connected to a tap (1) by a flexible hose (4) at both ends of which are electromagnetic valves (6,7). From the valve (7) in the washing machine, a water feed system (8) leads to the water container (9) of the machine, both valves being open when current is flowing but the machine valve opening and closing in conjunction with a level detector and the programme steps set by the programme controller (10). Should the water hose couplings become loose or the hose burst, a sensor (11) after the valve (7) in the machine sends impulses to a control (12) which will cut off the flow. Another sensor (13) is built into the water feed input at the base of the wash water container (9) so that the hose feed system is monitored by both sensors, the control (12) also opening or closing the valve (6) at the feed tap as required.

Title: Lathe machining non-circular piston rings - cyclically varies cutting speed by driving headstock spindle via eccentric round belt pulley
Inventor: FELLER OTTO
IPC: B23Q5/04
Filed: 1979-11-17
Abstract: The arrangement is intended for a lathe used for machining the inner and outer peripheries of non-circular piston rings either single or stacked (5). The headstock spindle (2) is motor driven (16) via a belt (19) with a spring-loaded tensioning roller. The spindle speed is cyclically varied during each revolution to optimise the cutting speed whilst the cutting tools (6,7) are moved radially to and fro (8-10 cam 14 and follower 13). The speed variation is achieved by using a circular belt (19) drive pulley, eccentrically arranged on the spindle (2). The spring of the belt tensioning roller may act as an energy store.
