Title: Intruder alarm system with parallel sensors - has voltage drop compensation by operational amplifier with feedback
Inventor: WOERL AUGUST
IPC: G08B13/08
Filed: 1973-06-20
Abstract: An intruder alarm system combines simple circuitry with satisfactory operation even after one of the alarm sensors has already been triggered, which may be performed by opening one protected door. The sensors are connected in parallel between earth and there is a tapping from a voltage divider across the supply voltage. The same tapping also feeds an operation amplifier the output of which is taken through a resistor to its reference voltage input. This input is also connected to earth through a capacitor.

Title: Learning aid for probability studies - polyhedrons mixed inside transparent box
Inventor: CAPECELATRO ACHILLE
IPC: G09B23/20
Filed: 1973-07-04
Abstract: When a dice is cast the probability that six comes up is in the ratio 6:1. In a polyhedron the ratio depends on the number of faces. To aid with such studies, a special enclosure has been designed comprising a base, top cover, storage tray, transparent inserts, preprinted paper sheets and definite number of sets of polyhedrons and spheres (i.e. say 150 of each) these are to facilitate study of isotopes. The internal faces of the box are shaped to facilitate rolling during shaking and form a solid stay during reading off. The claims are confined to the shapes, quantity and ratio of shapes of the polyhedrons also to the rules for random study teses.

Title: Vehicle windscreen wiper operating circuit - has electronic control circuit connected to excitation coil of switching relay
Inventor: KERSCHER MAX
IPC: B60S1/48
Filed: 1973-07-17
Abstract: The movable contact of the switching relay is connected to the wiper motor. The electronic circuit is a switch amplifier with two complementary transistors with emitter-collector layers in parallel with the current source. The exciting coil is in the collector circuit of the first transistor. There is a diode, two resistors and an RC link connected to the movable contact of the limit switch. The stationary contact is connected to the base of the second transistor. Resistors across the two transistors achieve the required operating delay time. The wiper operating time is independent of temp, whilst momentary breaking of the supply voltage does not upset the control.

Title: Modular transportable public toilet building - is independent of electric power, water and sewage connections
Inventor: BUENTZOW KARSTEN
IPC: A47K11/00
Filed: 1974-02-11
Abstract: The toilet installation unit consists of two main components which are the cabin and the floor with the container. The outside walls which are clamped to the floor can be replaced if necessary, by a door, automatic dispensers, windows, waste disposal boxes and ventilating slots.

Owing to the light weight of the glass fibre reinforced plastics the toilets are readily assembled manually without using a crane or lifting machine. The toilets are readily stored in dismantled state. The modular unit, for example, has approximately hexagonal shape in plan view and, together with the container tank and the roof and floor, is used for forming a stable unit with walls. The outside walls are connected to the floor element and the joint is sealed with commercial rubber sealing.

Title: Cigarette making machine paper cutting unit - pressure arm connected with paper feed and adhesive applicator on start up
Inventor: EHLICH KLAUS-DIETER
IPC: A24C5/47
Filed: 1974-05-03
Abstract: A cigarette making machine in which cigarette lengths incorporating filter tips are fed towards adhesive coated cut pieces of wrapping paper which are rolled around them, has a cutting blade which is pushed against the tensioned moving paper to cut it into lengths, a spring loaded rod carrying a tensioning roller which held against the paper. On start up, a contact passes a signal to a pulse shaper feeding a storage device followed by an amplifier which actuates an electromagnet so that a spring loaded rod is forced downwards to press a tensioning roller aginst the paper following the cutter blade. At the same time, a pulse device connected with the storage device operates with the cigarette and filter length feed system so as to bring the filter paper into contact with the adhesive applicator roller and bring the paper feed roller immediately after the tensioning roller into contact with a pair of pinch rollers so that the paper feed is brought into action.

Title: Suitcase with support frames for panels - has two interfitting grooves and arms providing alignment for lid closure
IPC: A45C5/02
Filed: 1974-05-29
Abstract: When the suitcase is closed a peripheral sealing strip, which is moulded onto a bead at the bottom of the lid frame, sealingly engages in a groove in the frame below. As an extra positioning and sealing means the bead has a recessed groove which is adapted to the edge of the outer arm of the lower frame which in fact defines the other groove, so that in addition the arm engages in the recessed groove when the case is closed. If on the lower frame the inner arm is longer than the outer arm which defines the groove for the sealing strip the upper frame can be guided more easily to fit into the lower frame.

Title: Lubricant metering distributor appts. - has sequentially activated slide valves to deliver lubricant to piston-type dispensers
Inventor: BRICOUT HENRI
IPC: F16N25/02
Filed: 1974-08-12
Abstract: The apparatus has units including a dose-measuring piston moving in a cylinder comprising an outlet at each end and whose travel is determined by an adjustable stop. In combination with this piston, each unit also includes a slide-valve whose section is smaller than that of the piston, and mounted in a cylinder each end of which is connected to the corresponding end of the dose-measuring cylinder in the previous unit.
