Abstract: The contact disc is made of conducting springy material resting by its edges on a supporting surface. It is pushed in by an operating element perpendicular to this surface. When pushed in the contact discs connects with each other at least two contacts, and when pressure is released, it automatically returns to its initial state. The supporting surface and the contacts (2) are at some distance above the case (1) bottom (3), and a light emitting diode (15) is provided under the contact disc (9). The diode (15) is in line with a hole (21) in the operating element (4) and a hole (20) in the contact disc.

Title: Pulse shaper generating sharp edge square wave - uses rectified AC input to operated Schmitt trigger that controls electronic switch
Inventor: IRNSPERGER JOHANN DIPL ING
IPC: H03K12/00
Filed: 1978-02-02
Abstract: The pulse shaper converts a periodic voltage into a rectangular voltage. The alternating input (UE) is applied both to an electronic switch (3) e.g. an op. amp. or a CMOS gate with buffer, and to a rectifier (1). The switch has a steep transition slope. The rectifier controls a Schmitt trigger (2) whose own output operates the switch, thereby causing the input to appear at the output (UA) with steep leading and trailing edges. When the input voltage drops below a given level the electronic switch is disabled, i.e. the trigger fails to operate. The shapes may be used between a quartz oscillator and digital circuitry in a CW system.

Title: Filter element for hot gas filtration - using mineral fibre medium on refractory metal frame with baffle around rim to prevent damage to fibres
Inventor: HOELTER HEINZ
IPC: B01D39/20
Filed: 1978-04-11
Abstract: Element for filtering hot gas streams uses a flat surface ceramic fibre element which can be woven or felted. This is mounted on a support frame with a protective rim around at least one side of the frame. This protective rim prevents cutting and nicking of the fibre element if vibration occurs which would then cause premature failure. The rim can be formed from flexible felt material or from curved plate. It can be made from a refractory steel or metal alloy, or ceramic refractory. The frame is also of refractory metal or ceramic construction. Used for filtering hot gas streams in the range 250 to 1400 degrees C. Avoids the problem of premature failure due to cutting along the edge of the frame.

Patent DE-2818479-A1 (DE)
Inventor: KAEMPF EUGEN
IPC: E05B29/04
Filed: 1978-04-27
Abstract: The safety lock serves for actuating a key-operated switch which has a multiplicity of switching positions, the object being to ensure that the key can be withdrawn only in a specific number of switching positions and is blocked in the other switching positions. So that the withdrawability of the key can be varied according to the particular requirements, the housing (10), in which the cylinder (20) of the safety lock is rotatable, has, in the bore (11), grooves which are arranged distributed over the circumference and which open into a bore portion (13) of larger diameter located at the front housing end. Arranged in this portion (13) is a ring (15) having fingers (16) which are located on the end face and which fill the grooves (12). The ring (15) and fingers (16) form a blocking member (14) which consists of plastic and from which specific fingers can be selectively broken off. Lamellae (21) of the lock cylinder (20) which form tumblers can penetrate into the grooves (12) thereby exposed. The key (23, 24) can thus be withdrawn. <IMAGE>

IPC: C25C1/14
Filed: 1978-05-03
Abstract: The raw materials or scrap are dissolved at the anode in an alkaline electrolyte, which flows as a stream from the anode to the cathode, on which the Sn is simultaneously deposited; and a d.c. electric field is established in the liq. with its voltage increasing towards the cathode. In the pref. electrolysis cell, liq. is continuously circulated by a pump so it flows up an anode basket contg. the raw material. The liq. leaving the anode basket flows through a mesh electrode fed with its own power supply to create the d.c. field, and then flows through outlet pipes located on the periphery of the cell and returning the liq. to the pump. The perforated anode basket is pref. made of conducting material and located concentrically in a round cell. Used in recovery of Sn from e.g. scrap tin plate, scrap cans used for contg. foods; and tin coated vessels or pots, by deposition of the Sn on a circular row of cathodes.

Title: Extracting hops with carbon di:oxide under specified conditions - to give low polyphenol extract used in brewing
Inventor: MUELLER ADAM DR
IPC: B01D11/00
Filed: 1978-06-20
Abstract: Extn of hops or hops prods is effected using CO2 followed by vapourisation of the CO2 from the extract obtd. For extracting resins, tar oils and low mol wt. polyphenols, a temp range up to the CO2 critical temp. and a pressure range above the CO2 critical pressure during all the extrn. are used. The extract is either further extracted to obtain oestrogenically active cpds, or isomerised by mixing with absorbents and liquid CO2 at high temp and pressure to form isohumulane. The initial extract is used in brewing beer. The oestrogenically active cpds, are used in animal feeds as protein synthesising agent, or in the prepn. of cosmetic prods or bath additives. The process enables an extract contg. all the better cpds, the low M. W. polyphenols, and the hops oil cpds, avoiding the extrn of high M W polyphenols and chlorophyll obtd in previous CO2 extrn processes.

Title: Electrical plug connector with drip proofing - has elastic rings on plug body which fit in cylindrical socket recess
Inventor: BRUNNER DIETRICH
IPC: H01R13/52
Filed: 1979-02-06
Abstract: The plug and socket arrangement is primarily intended for industrial applications, for example for making connections to magnetically operated valves. The cylindrical extension of the plug body (1') covering the connector pins has one or more elastically deformable rings (10) on its outer surface. These rings bear against the cylindrical bore (8) of the socket housing (7). The rings (10) may be an integral part of the plug moulding and be in a slight recess (11). Alternatively they may be separate O-rings fitted into recesses in the plug body. As well as providing a seal against drips or splashes, the rings also assist in giving a firm location for the plug and prevent inadvertent loosening or disconnection. The cylindrical bore of the socket may be recessed in the region of the rings to assist the locating action.
