Patent DE-2435715-A1 (DE)
Title: Short circuit protection device for electrical apparatus - measures internal resistance of circuit using transistors in circuit with phototransistors
Inventor: ULDOKAT GUNTER
IPC: F23N5/08
Filed: 1974-07-25
Abstract: Circuits of this type have particular application in the flame control of boilers. The internal resistance of the circuit is dependent upon external influences and the internal voltage drop is measured by a detector which in turn operates on the external controls and can eliminate voltage reductions caused by the external control circuits. For example in a flame control device for a boiler phototransistors are influenced by flame brightness and the emitter-collector voltage is measured by a monitor. Increasing brightness reduces the emitter-collector voltage to a point where the detector signals the fuel control (R11) to take corrective action.

Patent DE-2441666-A1 (DE)
Title: Heating radiator made from plastics - has flexible connecting pipe for preventing expansion stresses and cracking
Inventor: GROSS ERWIN DIPL ING
IPC: F24H9/12
Filed: 1974-08-30
Abstract: The heating radiator made from plastics is connected to existing pipelines. The high expansion of the plastics radiator is compensated by connecting pipes which are subjected to bending. The connecting nozzles (9, 91) are connected to the pipes (7, 8) of the heating system with flexible bending connectors (10, 10a). These flexible connections are plain or convoluted tubes. In order to gain space for accommodating a flexible pipe length, it can be fitted into the radiator by displacing the connector relative to the radiator body. Hence no additional space is required on fitting of this radiator. This radiator is as compact as a similar radiator made from cast iron or steel. The extended flexible connecting pipes are fully concealed on the rear of the radiator.
Patent DE-2441746-A1 (DE)
Title: Testing device for pulse convertors in telephone systems - uses test pulse transmitter which simultaneously generates number of pulse trains
Inventor: PAATSCH SIGURD DIPL ING
IPC: H04Q1/32
Filed: 1974-08-30
Abstract: Test pulses are applied to the tested unit, and the beats of pulse trains generated by the sender are the same; the first pulse train, or a single pulse switches on and off the convertor pulse switching means; second and third pulse train control a comparator which links the pulses delivered by the convertor switching means with the second and third pulse train by means of gates; they form from the second and third pulse train comparison blanking pulses during which the switching means must or must not deliver converted pulses; when converted pulses appear outside tolerance limits fixed by the reference blanking pulse trains, and when converted pulses and/or pauses are absent within these tolerance limits, malfunction is signalled or recorded.
Patent DE-2442505-A1 (DE)
Title: Unglazed ceramic tiles pointing and cleaning - initially treating with wax, plastic or combined emulsion
Inventor: GERHAHER MAX DIPL ING
IPC: E04F15/08
Filed: 1974-09-05
Abstract: The process is designed to simplify the work of pointing up and cleaning the surface of non-glazed ceramic tiles, where pointing is carried out after the mortar bed, in which the tiles are laid, has set hard, and where the lack of glazing results in the retention of pores in the tile surface, with a danger of permanent scarring by mortar remaining in them and only removable by intensive chemical or mechanical action, or by scrubbing away the surface over the years - disadvantages which usually prohibit the use of otherwise attractive tiles of this type. Here the surface is treated, before laying or before pointing, with wax, or plastic, or with a wax-and-plastic emulsion. Pointing and cleaning are almost as easily effected as with glazed tiles, and the danger of permanent grease or other idrt penetration before completion is eliminated.
Patent DE-2444312-A1 (DE)
Title: Suspended overhead maintenance platform - has mast sections with endless ropes coupled to adjacent ones and actuating ram
Inventor: MORAVEC ALFRED
IPC: B66F11/04
Filed: 1974-09-17

Each intermediate mast section (2, 3) has an endless rope or chain (12, 13) extending for its range of extension. Each run (18 - 21) of rope or chain is coupled to the adjacent mast section so that they move in the same direction. The section acting as the frame tube (1) is coupled to the adjacent section (2) by one or more rams (8, 9). There can be one retraction ram coaxial to the mast sections, or two on opposite sides.
Patent DE-2445407-A1 (DE)
Title: Gas release test for heated plastics - involves measuring vacuum reduction by gas from specimen dipped in fused solder
Inventor: GAMALSKI JUERGEN ING GRAD
IPC: G01N7/16
Filed: 1974-09-23
Abstract: A quantitative measurement of the gas released by the action of heat on plastics used for the manufacture of printed circuit boards is effected in a quartz tube (7) which dips into the surface of a solder bath (3), surrounded by a heating element (1). The specimen (17) is secured by a holder-down (9) when a vaccum is produced in the tube to raise the solder to a given level. After the lapse of a certain time, the drop in the vacuum, caused by the release of gas from the specimen, is measured and regarded as proportional to the gas emission. The method is simple and requires no skilled personnel.

Title: Anticapsize device for inflatable liferafts - uses weight which stows in small space and is automatically activated on inflation of liferaft
Inventor: HORMES KARL-HEINZ
IPC: B63B43/04
Filed: 1974-12-17
Abstract: The device consists of a cylindrical sleeve (1), at one end fixed around the underside of the floor of the raft and at the other end carrying a weight (2) in the form of a ring. The whole is secured to the raft in such a way that on inflation the weight is freed and, being especially configured, not only extends the sleeve but also causes it to open out so that water enters through holes (3) increasing the stability of the raft. Should capsizing occur nevertheless the water will run out of the holes again; the weight will tend to assist righting.

Title: Overhead automatic transport system structure - has columns ensuring train safety on road vehicle collision with column
Inventor: HEIDELBERG GOETZ DIPL PHYS
IPC: E01B25/00
Filed: 1975-04-24
Abstract: The overhead rail guided automatic transport system is powered by travelling wave magnetic system. The support structure is designed so that the overhead transport system is not put out of commission should a road vehicle collide with one of the track supporting columns.

The details of the buffer storage designs, in which MOS techniques and field effect transistors are used, and in which shift registers with regenerating elements (RS1, RS2...), are used as basic storage elements are described at some length in several different alternative forms.

Title: Variable width fountain and pen nib - comprises wire which is bent into split pin shape and which is spring loaded outwards in tapering tip of pen
Inventor: FISCHER ALFRED
IPC: B43K1/10
Filed: 1975-07-08
Abstract: The fountain-pen nib comprises a wire (1) which is of half-round section bent into split-pin shape. The ink is drawn by capillary action along the faces of the halves in contact to the tip. It is spring-mounted, giving easy writing with constant density, and also shock-resistant. As the ink on the tip runs dry, it is merely replenished by pressing on the pen, and for drawing broad lines the pen is pressed right down to bring the end of the housing (7) into contact with the paper. Springs of various strengths can be used to suit requirements. E.g. when having to produce several carbon copies a strong spring may be used.

Title: Automatic seat belt release device - has delayed-action mechanism cancelling hook connection after certain traction has been exceeded
Inventor: NEBEL ERHARD
IPC: B60R22/32
Filed: 1975-09-05
Abstract: The two ends of the seat belt webbing (2a) are locked together by hook arrangement (3, 3a). Web end (2a) is fitted to casing (1). Hook (3a) is fitted on the end of a rocker lever (13) pivoting around a fulcrum (5) seated in a slot (6) of the casing (1). The shorter arm of the rocker lever is kept in engagement with the hook (3) by a leaf spring (4) and the longer arm is fitted with a spiral spring (7) which tries to pull the arm towards the webbing end (2a). When the traction on the webbing ends is so large that the force of the spring is overcome, the casing (1) moves relatively away from the engaged hooks (3, 3a) sliding in the slot (6). By this movement locking arm (9) becomes ineffective. At the same time the spiral spring (10) is wound-up and screw gear fitted at its end turns the cam (12) which presses down longer arm of rocker hereby pushing hook (3a) out of engagement.
