Patent DE-3820580-A1 (DE)
Title: Wheel
Inventor: KRAEMER ERICH
IPC: B60B1/00
Filed: 1988-06-16
Abstract: The invention relates to a wheel which is intended in particular for prams, push-chairs, doll's prams, trolleys, suitcase castors or the like. In the case of this wheel, in an axial extension of a guide bushing of the wheel hub, there is provided a protective sleeve which surrounds a bearing pin on the body frame and serves as a screen for the bearing region between the bearing pin and guide bushing, and as a protection against being soiled by lubricants and the like. The protective sleeve is expediently composed of plastic, metal, rubber or combinations thereof. The protective sleeve can be designed such that it is rigid or flexible or such that it can be compressed axially. The protective sleeve can be connected fixedly to the guide bushing and/or the wheel hub or can be connected to the frame. As a variant the protective sleeve may be arranged in an axially locked manner on the bearing pin. The protective sleeve may preferably be formed from a flexible and axially compressible piece of tube, such as a flexible piece of tube with a spirally extending reinforcement. Alternatively, the protective sleeve may also be directly moulded onto the guide bushing.

Patent DE-3831970-A1 (DE)
Title: Membrane system for controllable separation of substances by changeable permeation
Inventor: HEITBAUM JOACHIM PROF DR
IPC: G01N27/40
Filed: 1988-09-21
Abstract: There has hitherto not been a membrane whose permeation properties can be reversibly changed in situ. The membrane system is to make possible, by a brief flow of electric current, the permeation of different substances to be selectively or integratively varied. The solution comprises a multilayer membrane system: a support membrane, on which a porous electrically conductive layer is applied. This is coated with an electrically active polymer film which can be oxidised and reduced (see Fig. 1). The reversible changes of the redox states of the polymer produce different permeation rates through the film. The use of such a membrane system would be conceivable for increasing the selectivity of sensors which permeably separate off a gas phase (environment) from a liquid phase (electrochemical detection) by means of a membrane. A further potential use would be for example in conventional dialysis equipment or similar arrangements in which the variable permeation through membranes is exploited for separation of substances.

Patent DE-3835689-A1 (DE)
Title: Electrical power supply for electrical apparatuses
Inventor: LOTSPEICH ROBERT
IPC: H01R25/14
Filed: 1988-10-20
Abstract: At least one hollow profile is provided for fitting in or on a panel of a piece of furniture or a wall. Conductor tracks, which run in the longitudinal direction of the profile and are insulated from one another but are not insulated from the interior are provided on or in at least one of the inner side walls of the hollow profile. The hollow profile has a longitudinal gap whose width is less than the maximum unobstructed width of the hollow profile. A number of electrical pick-offs can be pushed into the hollow profile. Each of these electrical pick-offs has a block whose cross-section fits with play into the interior of the hollow profile. Contact parts for picking off electricity from the conductor tracks are seated on the block. At least one connecting device for an electrical cable is provided on an externally accessible part of the block. If a board is equipped with such an electrical power supply, then it is necessary only to insert into the hollow profile, from one of its ends, as many electricity pick-offs as are necessary, which may be distributed as required in the longitudinal direction, and it is then possible to connect cables at the desired points. The conductor tracks can also be arranged directly in a channel within the board, without any hollow profile.

Patent DE-3841839-A1 (DE)
Title: Valve arrangement
Inventor: SCHERER PETER
IPC: F01L7/02
Filed: 1988-12-13
Abstract: The opening movement of an inlet and exhaust valve of a cylinder of an internal combustion engine has hitherto been positively controlled by a camshaft, whilst the closing movement is brought about by a return spring preloaded in the opening sequence. In this the speed of the closing movement is limited by the inertia of the spring forces, thereby also limiting the speed of the engine. Since the camshaft also presses on the return springs during opening of the valves, the conventional timing of the valves leads to a considerable power loss. In order to permit a greater speed of the closing movement of the valves and to reduce the power loss, the closing movement of the valves in the valve arrangement is also positively controlled by cams of the camshaft.
Patent DE-3843954-A1 (DE)
Inventor: KOROSTENSKI ERWIN DIPL ING
IPC: F16C7/02
Filed: 1988-12-24
Abstract: A connecting rod for an internal combustion engine comprises a casting with a lug (1) for the piston pin and a half-lug (2) for a crankshaft bearing, which are interconnected by a connecting rod shaft (3). An elongated structural member (4) made of a material having a low coefficient of expansion, a low specific weight and a melting point higher than that of the material of the casting is cast into the connecting rod. The resultant tensile stresses set up in the casting material during manufacture of the connecting rod are relieved during operation before pressure is applied to the connecting rod. Hence, the weight of the connecting rod can be substantially reduced.

Patent DE-3906539-A1 (DE)
Title: Device for loading absorbent tampons or the like with dry ice
Inventor: MAASS HANS-DIETER
IPC: A61F7/02
Filed: 1989-03-02
Abstract: Dry ice can also be used for cooling of the human body. However, it is not available everywhere and, in general, it is not available for ambulant treatments. It must not come into direct contact with the skin of a patient because it may cause burns on the cutaneous tissue. The invention attempts to remedy this. For this purpose, the device has a holder for a tampon and for a carbon dioxide cartridge. By abruptly opening the cartridge the liberated carbon dioxide flowing out of the cartridge is selectively passed into the tampon with the result that dry ice, which evaporates only slowly, is produced in the tampon. The device permits dry ice to be produced instantaneously inside a tampon. The tampon loaded with dry ice can be used for ambulant treatments of humans and the tampon can also be applied on to the skin of the treated patient without any danger of burns caused by the dry ice on the cutaneous tissue.

Title: Method for controlling the hydraulic brake pressure in a vehicle
Inventor: MATSUDA SHOHEI
IPC: B60T8/173
Filed: 1989-06-09
Abstract: In a method for controlling the hydraulic brake pressure in a vehicle the period for which the hydraulic brake pressure is intermittently maintained is varied as a function of the reduction of the wheel speed relative to the vehicle speed, so that the said period can be prolonged if a large reduction occurs. Unnecessary adherence to the intermittent maintenance period is thereby avoided, in order to prevent the generation of unnecessary braking noise.
