Title: Bullet proof intruder resistant keyhole plate cover - has tongues fitting two angled parallel grooves cut into plate
Inventor: SAELZER HEINRICH
IPC: E05B17/18
Filed: 1980-09-06
Abstract: The covering device is held in its protective position by force of gravity, and moved out of it by a counteractive force, on a plate for a keyhole, esp. on an outside door exposed to weather. The plate (1) has two parallel guiding grooves (3,4) cut into it, at an acute angle from the horizontal. One is above, and the other below, the keyhole (5). The protective device (2) has two tongues (6,7) shaped out, parallel to the plate plane, complementary to the grooves. A stop piece, in the form of a batten covering a side of the plate, may be fastened to the side of the protective device, or monolithically formed on it. This can provide protection from bullets, as well as from rain and dust, and can also resist break-in.

Title: Pin template for recording workpiece shapes - has steel pins held in position by plastics or rubber clamps
Inventor: GRAMMEL MATTHIAS
IPC: B43L13/20
Filed: 1980-09-06
Abstract: A pin template consisting of movable wire pins for determining the shapes of workpieces can reproduce very small radii and height differences of workpieces. It can distinguish small changes in shapes of workpieces and enable them to be recorded. The template is placed perpendicularly upon the workpiece and then pressed until it assumes the shape of the workpiece surface. The steel pins are held in place by rubber or plastics fittings to form a negative of the surface contour. The template can reproduce angles up to 90 degrees as found on the shoulders of shafts. The dia. of the steel pins of the template are between 0.5mm and 0.75mm. The template enables views of parts to be produced quickly and economically.

Title: Method of utilising the sensible coke heat in dry coke quenching
Inventor: GALOW MANFRED
IPC: C10B39/02
Filed: 1981-02-28
Abstract: The invention relates to a method of utilising the sensible coke heat in dry coke quenching and to an installation for carrying out the said method. The object is to utilise the sensible heat of the hot coke better and more reliably to generate a constant amount of steam with parameters which are as constant as possible. The invention essentially achieves this by evening out the variations encountered in the heat supply resulting from the batchwise delivery of the hot coke on the steam boiler side, in particular, by essentially passing a relatively large proportion of the recycling (recirculating) gas past the steam superheater section and steam generator section of the heat exchanger system.

Title: Process and apparatus for the continuous production of aerated sugar masses
Inventor: ERNST EBERHARD
IPC: B01F7/00
Filed: 1981-08-05
Abstract: In a process for the continuous production of aerated sugar masses, such as masses for chewing sweets or the like, in which the flowable starting mass is exposed to an intensive shearing action on its passage through a closed mixing and whipping zone, with air supply and under pressure, a subsequent continuous drawing and laminating treatment follows by the mass exiting from the mixing and whipping zone being conducted under pressure through a gap formed between wall surfaces moved relative to each other and being subjected therein to a drawing treatment by the drag flow caused by the wall surfaces. In the aerated and drawn sugar masses obtained as a result, the air or gas portion supplied is present in a fine laminar form. The mixing and whipping of the sugar mass is carried out in a mixing and whipping apparatus having a rotor and a stator which are equipped with meshing mixing and whipping tools and are arranged in a closed housing, which is provided with feed lines for the sugar mass, the components to be added to it and the aeration gas, as well as an outlet for the aerated sugar mass. A drawing apparatus is connected to the outlet side of the housing of the mixing and whipping apparatus, which drawing apparatus is likewise composed of a rotor and a stator which enclose a gap between each other for generating the drag flow. <IMAGE>

Title: Device for fastening tension or security wires on posts or the like
Inventor: SCHULZ HANS-JOCHEN
IPC: E04H17/10
Filed: 1981-08-13
Abstract: The wish often arises, in the case of these devices, to use inserted dowels with screws engaging therein. This type of connection, which is releasable per se, is now to be designed for security fences in such a manner that, on releasing the screw, the wire held by it is destroyed. For this purpose, the screw is fitted, at its free end which cannot be screwed in, with a bore (5) for receiving the wire (10), to be precise in such a manner that, when the screw is turned, the wire is moved on a shear edge which destroys the wire if the screw is turned further. The shear edges are formed by a securing means (6) which is mounted such that it cannot rotate and through which the screw passes. <IMAGE>

Title: Mast-foot attachment in surfboards
Inventor: RAFELD KARL
IPC: B63B35/79
Filed: 1981-09-30
Abstract: The invention relates to a mast-foot attachment in surfboards, with a sleeve which is anchored in the board and into which the mast foot can be inserted, which has a hollow mandrel at its bottom end for the releasable attachment in the sleeve, which hollow mandrel can be expanded by means of a manually rotatable pin and in the expanded state holds the mast foot in such a way that it is axially locked to the wall of the sleeve. In order to obtain one-hand operation of the mast foot when unlocking and locking its axial displaceability in the sleeve anchored to the surfboard, axially running ribs and axially running grooves are provided on the hollow mandrel and the sleeve bore wall respectively, which ribs and grooves come into engagement with one another when the mast foot is inserted into the sleeve and produce a rotationally locked connection between mast foot and sleeve, for which reason the regulating ring rotatable with regard to the mast foot can be adjusted without turning the mast foot itself about its longitudinal axis, and the mast foot therefore does not need to be firmly held with the other hand.

Title: Device for longitudinally adjustable motor vehicle seats for combining the folding movement of the backrest with a longitudinal displacement of the seat
Inventor: BERGHOF HANS-JOACHIM
IPC: B60N2/12
Filed: 1981-11-04
Abstract: A device for longitudinally adjustable motor vehicle seats with a forward folding backrest for combining the folding movement of the backrest with an actuation of the seat counter to a longitudinal displacement of the seat has a gearing (43 to 49) which converts at least part of the folding movement of the backrest into a translatory movement of the seat. In addition, a locking control (33 to 42) which positively releases the lock (5, 6, 7) at the start of each forward folding movement of the backrest is provided with a memory (20, 49, 52) for the magnitude of the folding movement of the backrest and/or of the translation movement of the seat which after the release of the lock (5, 6, 7) does not clear the latter for transition into the locking state until the magnitude of the folding movement of the backrest and of the translation movement of the seat towards the rear has reached the magnitude of the previously executed corresponding forward movement. <IMAGE>

Title: Child protection device at workplaces
Inventor: DEY HELMUT
IPC: F24C15/36
Filed: 1982-02-17
Abstract: The invention relates to a device for the protection of small children at workplaces, in particular on electric cookers and work surfaces with cooking areas. With the device, the intention is that both free access for an operating person for a workplace is to be ensured and access to this workplace for children is to be prevented. This is achieved by a heatable safety rail arranged on the operating side of the workplace. Small children are deterred by the surface temperature of the safety rail without suffering burn injuries. The temperature level necessary can be achieved by suitable selection of an electric heating resistance. Free access for activities to be performed is afforded as a mechanical protection of the workplace against unauthorised access by small children is not present.
