Patent DE-3143839-A1 (DE)
Title: Contact lens
Inventor: PEYMAN GHOLAM A
IPC: B29D11/00
Filed: 1981-11-05
Abstract: The invention relates to a soft contact lens. This has a soft, highly oxygen-permeable polymer lens element, to the surface of which an ultrathin, optically clear, impermeable barrier coating has been applied. The barrier coating is not crosslinked and is the reaction product of an electrical glow discharge polymerisation process carried out in a gaseous atmosphere. The coating prevents diffusion of lipids and other large molecules from the tear film of the eye into the lens. The lens comprises silicone or polyurethane. The gas atmosphere essentially comprises compositions or compounds selected from the group including hydrocarbons, halogenated hydrocarbons, halogenated hydrocarbons and hydrogen, hydrocarbons and a halogen, and a mixture of two or more of these compositions or compounds. The surface of the fully finished lens is highly hydrophilic. This is achieved by the polymerisation process or by an additional process step by means of glow discharge in the presence of oxygen or argon.
Patent DE-3144534-A1 (DE)
Title: Electrical monitoring installation and monitoring fitting for water supply lines in buildings
Inventor: DICKE WERNER
IPC: G01P13/00
Filed: 1981-11-10
Abstract: The installation includes a time lag relay (4) at which a certain timespan, for example 10 minutes, can be set. When a stream of water, no matter how small it may be, flows continuously beyond the set time value downstream of the water meter in the distribution section of the water supply line of the building, then the time switch gives the command to close a shut-off valve (5) in the distribution section. The time lag relay (4) receives the pulse of the water flow from a sensing and pulse member (3) installed upstream of the shut-off valve. <IMAGE>

Title: Thread-forming device for use in combination with a punching operation
Inventor: HERRMANN WALTER
IPC: B23G1/16
Filed: 1981-11-14
Abstract: The invention relates to a thread-forming device which can be used in a punching machine. Here, recesses are provided in the core hole for the thread in conformity with the cutting lands of the tap so that the tap can be moved at rest into the core hole to the full depth.

Patent DE-3147753-A1 (DE)
Title: Process and production mould for producing boards, and boards produced by the process and in the mould
Inventor: SCHOEPFEL THEODOR
IPC: B44C5/04
Filed: 1981-12-02
Abstract: The invention relates to a process and to a mould for producing boards having a decorative and/or wear-resistant surface, solids being embedded in a hardened casting compound, and to boards produced according to this process. The invention is characterised in that one board is produced in each case in the mould in approximately the desired later board thickness, by first producing on at least one mould inside the later visible side as a base layer without solids and then casting the casting compound with the incorporated solids around this base layer. In the process according to the invention, the base layer is formed from a transparent and stabilised plastic by spraying or casting it in, whereupon the barrier layer, which then carries the solids and at the same time makes a joint with the casting compound, is fixed to the base layer. On the back of the board, a reinforcement is fixed in the casting compound, as well as, if appropriate, projecting anchoring or fixing elements. The back of the board can also be roughened by sprinkling with, for example, quartz sand. The boards produced by the process can be used as table leaves, for facade facing, for decorative covering of building surfaces, for floors or stair treads and the like.
Patent DE-3200634-A1 (DE)
Title: MIS field-effect transistor with charge carrier injection
Inventor: TIHANYI JENOE DR ING
IPC: H01L29/10
Filed: 1982-01-12
Abstract: The ON resistance Ron of a vertical MISFET increases superquadratically with increasing maximum blocking voltage. Ron is reduced by injecting charge carriers into the drain zone (1) via an injector zone (4) situated near the source zone (3). This produces a higher conductivity and consequently a lower Ron. So that this effect only becomes operative at higher drive level, a zone (5) in combination with which the injector zone (4) acquires a zener diode characteristic is embedded in the injector zone. <IMAGE>

Title: Small electrical apparatus for heat treatment of food
Inventor: HONOLD PETER DIPL ING
IPC: A47J27/62
Filed: 1982-02-08
Abstract: In a small electrical apparatus for heat treatment of food, such as an automatic waffle cooker (10), grill, toaster or the like, a light-emitting diode chain (20.1 to 20.7) is provided at an easily visible point, for example in the hinge part (18) and indicates the time which has elapsed in the heat treatment cycle. It is preferably arranged directly adjacent to the adjusting device (19.1) of a bimetallic temperature switch (19). The circuit contains an electronic power circuit breaker (29) which switches on the bimetallic temperature switch (19) in the heating circuit or itself supplies the heater with voltage. It is driven by a programme controller (28) which evaluates switching pulses of the bimetallic temperature switch and sets the light-emitting diode chain and another indicating light (20.0) in operation. An improved and more versatile design of the heating curves can be achieved matched to the control variables which are determined by the recipe and apparatus, in order to improve the baking result using the programme controller.   <IMAGE>
