Patent DE-2401284-A1 (DE)
Title: Buoyant soap with lightweight core continuously produced - and cut transversely between successive cores to give separate bars
Inventor: OLSSON KARL-GUSTAV RUNE
IPC: C11D17/02
Filed: 1974-01-11
Abstract: Bars of soap possessing a lightweight core which causes the entire bar to float in water are made by forcing the soap material into a mould, a light-weight core is then pushed into the central region of the soap in the mould then a further portion of soap material is applied to cover the core, then a further lightweight core is applied centrally, and so on repeatedly to produce a continuous column which is then cut across intermediate planes between the cores to produce bars of soap each having a lightweight core. Pref., the upper side of each batch of soap material pressed into the shape of a shallow funnel, in order to centre the succeeding lightweight core. The method is used for making bath soap, and also for soap intended for washing in sea water or lake water. The bar immediately floats if dropped and is thus easy to recover.

Title: Air bed with surface of variable hardness - has heater causing air to expand thereby tightening up surface
Inventor: KIRSCH UDO WOLFGANG
IPC: A47C21/04
Filed: 1974-02-01
Abstract: The bed comprises a heat-insulated plastics cover into which air is pumped until the bed is inflated. The plastics cover contains a heating system which is secured by holders along the longer side and heats up the air to the desired degree so that the nature of the bed can be varied. Thus if the air inside the bed is hot it expands and causes the bed to be taut and hard whilst if the air is cold the bed is relatively soft. The heater can include a thermostat and terminals which are plugged into the mains. The bed itself can be mounted on a bed frame if required.

Title: Ignition circuit for otto-cycle engine - has differential amplifier coupled to ignition pulse generators and feeding comparator producing switching signals
Inventor: HEIMPRECHT ULRICH STEFAN ING G
IPC: F02P17/10
Filed: 1974-07-26
Abstract: The ignition circuit, for an Otto-cycle engine, has two generators which produce the ignition pulses, and are coupled to the primary side of the ignition coil and to the inputs of a differential amplifier. A circuit coupled to the output of the differential amplifier converts the voltage waveform at that output into a squarewave. This circuit contains a comparator that compares the mean of the differential amplifier's output with its actual output. The output of the comparator output remains at its 'close' level until the actual value is greater than the mean value, whereupon it changes to its 'open' level.
Patent DE-2443553-A1 (DE)
Title: Breech block arresting mechanism for automatic pistol - ensures that breech block remains open after firing last cartridge
IPC: F41A17/74
Filed: 1974-09-11
Abstract: The breech block arresting mechanism is used in automatic pistols. The mechanism is designed to eliminate the possibility of inadvertent faulty actuation of the pistol. The hammer (2) is released by an actuating lever (1) which actuates the breech bolt holder (9) when the breech block is open. After the last cartridge has been fired, the breech block holder (9) is longitudinally moved by means of the closing spring force into a position where it is in effective contact. The actuating lever (1) travels through a shorter path on actuating the breech block holder (9) than on releasing the hammer. When the actuating lever is lifted inadvertently on firing then the breech block is not arrested before the firing of the last cartridge.

Title: Hollow gudgeon pin for pistons - has barrel or double cone shaped hole of widened cross section at max pressure point
Inventor: SCHIEBER GERHARD ING GRAD
IPC: F16J1/16
Filed: 1974-11-26
Abstract: The risk of deformation of the gudgeon pin to an oral cross section, which can impair the hydrodynamic action of the lubricant film, is reduced. The pin is designed so that peak stress loadings are avoided. The cross section of the bore (4) is increased where there is a high surface pressure, the widest section being at the maximum pressure point. This is at the section between the inner edge of the eye of the gudgeon pin and the opposite edge of the small end bearing. The widening of the bore is double cone shaped or barrel shaped. The section between the maximum pressure zone is cylindrical.

Title: Composite tapes for stamp deformation contrast labels - using rubber modified methacrylate for high contrast markings
Inventor: CHAZAN DAVID J
IPC: C09J7/29
Filed: 1975-01-11
Abstract: Malleable tapes incorporating a transparent primary tape >= approx. 0.05 mm thick made of polymethylethacrylate modified by an elastomer so as to whiten when deformed For using in labelling machines producing marks by selective character stamps which exceed the critical strain of the primary tape. The rubber modified PMMA tapes tolerate sufficient deformation to ensure adequate whitening over the whole deformation design. The laminated structure suppresses the halo effect associated with fringe strains in homogeneous tapes, improving character contrast against the background colour. PMMA based tapes are dimensionally stable, highly tear resistant.

Title: Metal oxides prodn from metal chlorides - by decomposition in fluidized bed with removal of liquid metal chloride impurities
Inventor: FENNEMANN WOLFGANG
IPC: C23G1/36
Filed: 1975-01-27
Abstract: Process for working up solns. contg. metal chlorides which are liquid at room temp. (I) and those (II) which are splittable into metal oxides and HCl, whereby the effluent gas is first mechanically freed from solid material, the liq. (I) is recovered separately, the effluent gas is charged before entry into the splitting reactor to concentrate the soln. to be worked up, and the HCl is then absorbtively bound, whereby a metal chloride soln. is charged to the splitting reactor whose concentration of (I) is higher than that of the soln. to be worked up, and an amount of liq. (I) corresponding to the metal chloride soln. added is sepd. from a side stream of gas diverted from the effluent gas stream. Process overcomes problems associated with known processes in which the solns. to be processed contain metal chlorides which are liq. and do not split under the reaction conditions, but vaporise and pass into the gas stream or remain in the reactor tocontaminate the solid prod., while the volatile prods. pass to the splitting reactor during the concn. stage and accumulate there, eventually stopping the splitting process.

Title: Wheel stand for caravan - comprises moulded plastic chock having support surface on rear
Inventor: SCHROEDER HEINZ-GEROG
IPC: B60T3/00
Filed: 1975-05-03
Abstract: The plastic moulded wheel chock has parallel upright walls (1) on either side of the wheel and profiled floor surfaces at each end. One end has a normal curved profile (2) to act as the obligatory wheel chock, while the other end has a humped profile (3) on which the wheel can be supported without rolling off.

Title: Catamaran or canoe storage method - has hull of one boat made smaller to fit within split hull of other
Inventor: KRAFT URSULA
IPC: B63B7/02

Abstract: One of the two hulls is made smaller than the other, by an amount equal to the hull thickness. The larger (2) is split (3) horizontally either where it is widest or at the join between sides and deck so that the smaller can be fitted inside. The joint between the two parts of the larger hull is arranged to be watertight. Provision is made for securing all parts together when the smaller hull (4) is in the larger. This can be using screws or bolts with threaded wingnuts to tighten across the flanged joint. The joint can have a S-shape or other sinuous form to assist alignment and watertightness.
