Title: Radio network
Inventor: BLANSCHEFSKI MICHAEL DIPL ING
IPC: H04M1/72511
Filed: 1988-06-18
Abstract: The object of the invention is, in a radio network with radio devices which in each case scan for a free channel from a pre-defined number of radio channels, not to carry out the channel selector changeover according to a fixed timing pattern, which is time-consuming. The object is achieved by abruptly discharging a capacitor (C1) belonging to a peak voltage rectifier (14) of a muting device at the start of each channel changeover by means of a discharge pulse of a microprocessor circuit (21) of the radio device. This modifies the muting device output voltage in each free radio channel, causing the microprocessor circuit to switch the channel selector (23) to the next radio channel. A preferred field of application for the present radio network is a radio network with cordless telephones of the Deutsche Bundespost. The drawing shows a block diagram of the essential parts of the invention. <IMAGE>

IPC: E03B7/07
Filed: 1988-08-26
Abstract: Shut-off valves for domestic water supply lines are present in every supply line. However, in each case a filter with a bypass valve is still desired in addition. For reasons of economy and in order to avoid the space requirement for these three apparatuses, it is proposed to combine the shut-off valve, the filter and the bypass valve in one housing. <IMAGE>

Inventor: WHEELER CLIFTON E
IPC: G03F7/00
Filed: 1989-02-10
Abstract: An infrared window having a metal conductive grid deposited below the front surface of the window is made by exposing a photoresist (16) on the surface of the infrared window (10) to grid pattern. The photoresist is developed and the surface of the infrared window is etched to produce channels (18) in the window's front surface corresponding to the grid pattern on the photomask. The front surface is then coated with a conductive metal layer and a lift-off process is used to remove the remaining photoresist and metal which has been deposited on the photoresist. An antireflection coating (ARC) may thereafter be applied to the front surface of the infrared window. The window may be zinc selenide and the photoresist is preferably a postive photoresist. <IMAGE>

Title: Press-in plastic lid
Inventor: HELLWIG HERBERT
IPC: B65D43/02
Filed: 1989-02-08
Abstract: The invention relates to a press-in plastic lid having a peripheral wall which extends upwards from the lid base and on whose end a projecting resting part is provided, and having a gripping part which is located above said resting part, extends inwards parallel to the base, and whose inner edge surrounds an opening. The aim of the invention is to design such a press-in lid in such a way that a plurality of identical press-in lids can be kept in a stack without the risk of them collapsing during transportation or due to vibrations when they are being stored. To achieve this aim, the press-in lid according to the invention is provided with a thermoformed inner part of its base, whose outline contour is slightly smaller than the outline of the opening surrounded by the inner edge or stop face of the gripping part. When identical press-in lids are stacked one above the other, the thermoformed inner part projects, whilst maintaining a slight movement clearance, through the opening, surrounded by the inner edge of the gripping part, in the press-in lid lying at the bottom and forms a stack which is secure against slipping. The slight movement clearance between the individual press-in lids in the stack has a favourable effect on its overall stability.

Title: Lighting system for bicycles
Inventor: FROEHLICH GEORG
IPC: B62J6/06
Filed: 1989-04-10
Abstract: Usually, lighting systems for bicycles are supplied with current by a dynamo. The disadvantage of this is the necessary frictional engagement of the separate dynamo with an appropriate wheel of the bicycle. Especially when it is damp this frictional engagement is not always achieved resulting in inadequate lighting. In the lighting system according to the invention, a generator is provided in that the generator coils (13, 14) and an accumulator (15) are permanently connected to the frame whilst the permanent magnets (21) of the generator are integrated into a wheel of the bicycle. A lighting system which is designed in this way operates without frictional engagement and is thus reliable even in damp weather. The lighting system according to the invention is particularly suitable for arrangement in the region of a front wheel (10) of the bicycle. <IMAGE>

Patent DE-3935773-A1 (DE)
Inventor: HENDEL HORST DIPL ING
IPC: H01H1/58
Filed: 1989-10-24
Abstract: The invention concerns the establishment of an electrical connection for the supply of a switching current between one end (2) of a connector wire (1) and a contact piece (7) mounted on a contact support (3), contact being established through a hole (4) in the contact support (3). In order to simplify production of this kind of contact, the invention calls for one end (2) of the wire to be joined to an extension (10) formed by a stamping procedure in which the hole (4) in the contact support (3) is utilized as a tool to shape the extension (10). This ensures that the dimensions of the extension (10) match in optimum fashion the dimensions of the hole (4). In addition, the fact that the extension (10) is formed in the hole (4) itself makes it unnecessary for the end of the wire carrying the extension (10) to be positioned relative to the contact support (3) or the hole (4) in it. The process is of particular use in the production of connections for switchgear and relays.

Patent DE-3940576-A1 (DE)
Inventor: FASSBINDER HANS-GEORG DR RER N
IPC: G01F1/80
Filed: 1989-12-08
Abstract: In one class of measuring devices, a rotary element, which is carried by a shaft, is driven at a constant speed of rotation and deflects the mass flow impinging axially on the rotary element radially, imparting to it in the process a tangential velocity component, is used for measuring a preferably heterogeneous mass flow. The torque dependent on the mass flow is measured at the shaft. For this purpose, a first spur gear attached to the shaft is provided, the said gear being in engagement with a second spur gear. The second spur gear is mounted in a carrier element which, for its part, is mounted to allow rotation about the axis of the shaft and is held firmly in its position by a force-sensing device. To improve the measuring sensitivity, the second spur gear has a second tooth engagement, opposite to the first spur gear, with an internally toothed gearing, which is likewise mounted to allow rotation about the axis of the shaft and is made to rotate by a driving pinion. A rotational body made to rotate in the same direction as the shaft is furthermore frictionally connected to the carrier element and/or the first spur gear. The strength of the hydrodynamic frictional engagement is adjusted so that the frictional torques of the first and second spur gear are compensated by the frictional torque of the frictional engagement.

Title: Random colouring action - uses loose bodies rolling on moving web to transfer medium from their rolling surfaces
Inventor: ANNEN OSKAR DR
IPC: D06B11/00
Filed: 1990-01-20
Abstract: To give a random colouring effect to paper or fabric webs, the web is passed continuously through an application zone where there are a number of loose bodies, close to each other, which are continuously or intermittently soaked with a dyestuff or etching solution to be transferred to the web. As the bodies move against the web by friction movement, the application of the medium to the web is random and uncontrolled. Pref. web is a woven fabric, to be treated with a dye solution or suspension. The treatment medium is applied to the transfer bodies from above, by spray or pouring or as drops. Before the web enters the application zone, it can be dyed with at least two different dyestuffs, to have an etching solution transferred by the bodies to act on one or a defined number of dyestuffs present in the web. The transfer bodies are irregular shaped stones, with a smooth and rounded surface pref. with a porous surface quality, and pref. pumice stone. ADVANTAGE - The technique gives a continuous colouring application, in a simple process, giving effects which cannot be reproduced.
