Patent DE-2813234-A1 (DE)
Title: Keyboard arrangement for miniature electronic devices - has slotted panel using finger nail or tip for actuation
Inventor: HILD MANFRED
IPC: G04G9/00
Filed: 1978-03-28
Abstract: The input keyboard is esp. designed for miniaturised electronic equipment and small calculators, such as wrist--watch types. The input panel comprises a cover plate (1) in which are a number of slits (2) corresponding to each alpha-numeric character. The required data is "keyed" in by insertion of a finger nail through the appropriate slit. An alternative arrangement consists of metal contact plates carrying alternating electric charges. By contact with the finger tip, the skin itself forms a conducting path between the plates or points to generate a current pulse. A further alternative system is based on a seven-segment panel of actuating devices whereby the character is keyed in by "writing" its shape with the finger tip, operating the respective elements in so doing.

Title: Froth forming liquids are aerated by submerged propeller - having overflow weir for froth with air injector to re-entrain froth, mix it with air and inject it into eye of propeller
Inventor: RECK ANTON
IPC: A01C3/02
Filed: 1979-04-20
Abstract: Liquids which tend to froth are aerated by having a submerged propeller inclined at an angle to the liquid surface. Gas, esp. air, is introduced into the eye of the propeller. There is an overflow weir for the froth which is self adjusting dependant on the liquid level. It is connected to the propeller by a flexible connection. Froth is drawn back down into the propeller by an ejector device which uses the gas or air to entrain the froth. Air can be supplied from a fan. Used esp. for aeration of liq. manure where it is desirable to use the froth to retain components such as NH3, reduce odour and reduce the noise from the agitator. The mixer will operate under extreme conditions to allow desired biological reactions to be rapidly brought into action and be maintained at elevated temps.

Title: Flame cutting of continuous castings - with simultaneous removal of slag beards via streams of gas supplied by nozzles moving synchronously with flame cutting burner
Inventor: HENNECKE FRANZ
IPC: B22D11/126
Filed: 1979-06-23
Abstract: The cast billet or slab is cut via a burner mounted on a flame cutting machine; and the beards formed during the cutting operation are removed via one or more nozzles directing one or more jets of thermal and/or kinetic energy onto the beards, so the latter are burnt and/or blown away before they solidify. The nozzles travel synchronously with the burner. The nozzles pref. provide jets in at least two directions, the jets consisting of a hot or combustible gas, or only of a high velocity stream of gas. The pref. flame cutting machines are fitted with a bruner and one or more nozzles blowing the beards away during flame cutting. The nozzles may be mounted on the burner or on a separate trolley moving together with the burner. If the beard is allowed to solidify, it can only be removed by costly machining operations; the invention eliminates this problem.

Title: Roving feed interrupter for spinning frames - has sliding roving guide which draws roving sideways out of drafting rollers
Inventor: KAMP HEINZ
IPC: D01H13/18
Filed: 1979-07-26
Abstract: Spinning frame has a roving guide device behind the rear drafting rollers which can be moved laterally beyond the end of the rollers to stop the roving feed in the event of yarn breakage.

Title: Clamp for round workpieces - has rotatable self locking jaws with V=grooves to receive workpiece
Inventor: VOCKENTAENZER NORBERT
IPC: B25B1/24
Filed: 1979-10-31
Abstract: The clamp for round workpieces (1) has two hinged jaws (2) which fit on opposite sides of a third jaw (4). The pair of jaws are mounted on a pin (9) fixed to a support member (14) whilst the third jaw (4) is mounted on a pin (8) fixed to the support (13). Both supports slide on guides fixed to a central support (11) and can be moved by a screwed rod with right (21) and left hand threads (22). The jaws have V grooves with the axes of symmetry offset from the centre lines of the pivot pins. Thus when the jaws swing to the horizontal position they become self-locking.

Title: Anti:adhesion coating for glass ceramic surface, e.g. hot plate - contains polysiloxane with metal oxide and/or amino gps.
Inventor: STEINBACH HANS-HORST DIPL CHEM
IPC: C03C17/30
Filed: 1979-12-29
Abstract: Antiadhesion coating for glass-ceramic surface contains polysiloxanes (I) contg. metal oxide and/or amino gps. It can also contain a detergent and/or surfactant. The coating is esp. useful on cooking surface, esp. hot plates, to prevent firm adhesion of residues and to prevent the formation of water, metal and chalk stains. In an example, an aminosiloxane was prepd. by hydrolysis of a mixt. of dimethyldichlorosilane, bromomethyl-dimethylmonochloro- silane and methyl-bromo-methyldichlorosilane. After equilibration with bleaching earth at 120 deg.C and filtration, the siloxane obtd. was reacted with cyclohexylamine, filtered and washed with cyclohexylamine. A glass ceramic plate was treated with the siloxane, then sprinkled with cane sugar and heated to a temp. at which this caramelised completely. After cooling, the caramelised sugar could be pushed aside with a cloth and did not adhere to the plate.

Title: Ultrasonic antitheft system for motor car - has several ultrasonic beams monitoring assigned zones for increased sensitivity
Inventor: HUBER WERNER DIPL PHYS DR
IPC: B60R25/10
Filed: 1980-02-02
Abstract: An ultrasonic detector system is used to protect road vehicles from unwanted entry. The system utilises an ultrasonic transmitter (12) that is mounted within the vehicle. The transmitting element is positioned relative to fixed prisms such that a number of emission beams (14) are generated. These are selected such that all doors are enveloped.

Title: Emergency electrically motor driven alarm siren - can be fastened to belt and when actuated cannot be turned off without special tools
Inventor: MAERZ SEN THOMAS
IPC: G08B15/00
Filed: 1980-03-06
Abstract: The alarm consists of a housing (12) containing a siren (2) driven by an electric motor (3), a press button (4) held in place by a spring (7) the end of the button having a stem (5) which when pushed inwards, completes the circuit by pressing a contact spring (10) against the return wire (11), and then leaves the holder (8). A swivel ring (13) allows a carrying strap to be attached to the alarm. The rear part of the main housing (12) is smaller and contains the batteries (18) and an on-off switch in the form of a contact screw (14), connected to the return wire for the batteries (18). Concealed grub screws, either side of the closure disc in the base (16) can be screwed in to a small groove in the contact screw (14), and ensure that when the alarm button (4) is pressed, the siren cannot be switched off and will sound until the batteries (18) expire or the grub screws are undone. This prevents an assailant from muting the alarm without using suitable tools. The alarm can be easily carried by shoulder straps or hung from the belt, thus deterring an attacker from attempting to remove it.
