Title: Food preserves sterilisation - in autoclave working tank by hot water circulating from storage tank
Inventor: REUTER WALTER ING GRAD
IPC: A23L3/10
Filed: 1979-11-28
Abstract: Food which is packed in tins or glass bottles is sterilised in pressurised autoclaves with a working tank and a storage tank. Water is steam heated in the latter and is transferred to the former where steam injection maintains the sterilising temp. Near the end of the sterilising period the boiling water is mostly returned by compressed air or gas to the storage tank, and the remainder is recycled. At the end, the remainder is mixed with cold water and drained off. The new pressurised autoclave consists of a working tank and a storage tank above it. The headroom of the working tank is fitted with a compressed air pipe controlled by a valve. The headroom of the storage tank is linked to the former through a connecting pipe with a valve, controlled by a pressure regulator.

Title: Sinker for angling line - is shaped as flat isosceles triangle with shorter base than sides and bore for line perpendicular to base
Inventor: MEYER WILLI
IPC: A01K95/00
Filed: 1980-02-15
Abstract: The winged sinker for an angling line (2) is of triangular shape. shape. It is formed as an isosceles triangle whose base (1) is shorter than the two other sides. It contains a bore (7) for the line whose centre line coincides with the perpendicular on the base.

Patent DE-3019831-A1 (DE)
Inventor: MISAWA TOSHIYOKI
IPC: G04F5/06
Filed: 1980-05-23
Abstract: A circuit for compensation of timekeeping inaccuracies induced by ambient temperature variations. A bridge circuit having a temperature sensitive resistive element in one branch and a resistance of programmed variation in the other branch outputs a changing unbalanced voltage to drive a comparator. A change in polarity of the comparator output detects the ambient temperature and causes a counter controlling the programmed resistance to output signals to a timekeeping regulation circuit whereby timekeeping is made accurate. Initial corrections are made in the programmed resistance branch to adjust for off-design performance of the vibrator in the timepiece oscillator.

Title: Compressible paste bottle sealing device - has boss on membrane pulled out of outlet by internal pressure
Inventor: RODER EBERHARD
IPC: B65D83/00
Filed: 1980-10-15
Abstract: The sealing device is for a bottle containing paste or fluid and closed at the bottom by a piston, the latter being locked in position by the pressure generated when an elastic portion of the bottle is compressed, and drawn inwards by the vacuum so as to thrust the contents forward when this portion is released, the outlet simultaneously shutting. At the top of the bottle (1) is a chamber (6) sealed off from the interior accommodating the contents by an elastic membrane (7). Mounted on the membrane is a boss (8) extending into the outlet opening (4) so as to shut it off. When pressure is generated inside the bottle, this causes the membrane to pull the boss out of the opening.

Title: Push-button keyboard for telephone instrument - has spring contact which also hold keys in off position
Inventor: GAHL ANDREAS
IPC: H01H13/80
Filed: 1980-10-21
Abstract: The keyboard assembly has a moulded base (1) with a pair of vertical guides (7,7') for each key or button (6). In the space between the guides spring loaded contacts are arranged (3,4) and are attached to leaf springs. The button (6) has a corresponding projection (13) which is a sliding fit in the recess formed by the guides (7,7').

Title: Accelerated humification of organic matter - by maintaining humidity fresh air supply and fermentation temp.
Inventor: MICHEL-KIM HERWIG
IPC: C05F17/00
Filed: 1980-11-12
Abstract: The transformation of organic matter into humus (humification) is accelerated by relayering and aeration during the fermentation process. The material (of vegetable or animal origin) is prepd. by a comminution to the optimum size. During the entire composting process, a set relative humidity is maintained, combined with a metered aeration, CO2 extn. and a constant temp. through a corresp. heat dissipation. This results in a higher fertilising value and in accelerated fermentation without any admixture of chemicals.

Patent DE-3100724-A1 (DE)
Title: Method for monitoring the presence of vehicles within certain traffic areas
Inventor: SCHUERMANS PETER ING GRAD
IPC: G08G1/042
Filed: 1981-01-13
Abstract: The invention relates to a method for monitoring the presence of vehicles within certain traffic areas, by means of at least one induction loop, the change in inductance of which loop is detected via an oscillator and forwarded to an evaluating circuit. To detect a change in inductance via the oscillator and to forward this change to the evaluating circuit without the possibility of false signals being triggered due to a prolonged stay time of the vehicle or due to changes in the environment, the pulses generated from the oscillations of the oscillator are converted into a time signal which is proportional to the oscillator frequency and is digitally measured by means of a constant basic frequency and in which a change resulting from the change in inductance is determined in the evaluating circuit and is processed further as a control signal when a programmed threshold value is exceeded. To determine the direction, at least two induction loops having different oscillator frequencies can be used, the different time signals of which are supplied via a change-over switch to a common evaluating circuit having a constant basic frequency.

Patent DE-3107284-A1 (DE)
Title: Luminaire
IPC: F21V19/00
Filed: 1981-02-26
Abstract: The invention relates to a luminaire having a concave mirror reflector in the sealed interior of which there is arranged a luminous element having a transparent housing, preferably an incandescent lamp. In order that when the incandescent lamp is inserted or exchanged the interior of the concave mirror reflector should remain tightly closed, provision is made of transparent means with the aid of which the interior is isolated from a receiver chamber for the incandescent lamp and thus always remains sealed against the environment. It is also advantageous to use a sealing element to seal against the environment the receiving chamber for the luminous element together with its housing and the bulb of the incandescent lamp. In order that only incandescent lamps having prescribed lighting and electrical values can be inserted into the luminaire, it is advantageous to provide an adaptor having mating faces, the luminaire itself having assigned mating faces. <IMAGE>
