Patent DE-3165260-D1 (DE)
Title: Method of making fibre-reinforced moulded-plastics parts
Inventor: RUDOLF A
IPC: B29C70/34
Filed: 1981-10-27
Granted: 1984-09-06
Abstract: 1. Process for the preparation of fibre-reinforced plastic mouldings having a prefabricated inner body (1) possessing a plastic cover (3) with a multiaxially stressable fibre composite, the prefabricated inner body consisting of plastic reinforced with fibres running in the lengthwise direction and the proportion by volume of fibres in the inner body being greater than in the cover layer, characterised in that inner bodies which initially correspond roughly to the length of the moulding are produced by passing rovings, led through a vacuum chamber, through nozzles into a liquid resin impregnating bath, laying the thus impregnated strands parallel in a moulding tool, compressing them lightly by means of the top of the moulding tool and leaving them in the moulding tool until the resin has hardened, that thereafter these inner bodies are taken from their moulding tool and laid, arranged singly or in a plurality, in a mould adapted to the shape of the moulding, and the remaining residual volume of the mould is then filled with fibre mats which surround the inner bodies, the said mats having beforehand been compressed and stabilised in the pressed state, and that thereupon the mould is introduced into a reduced-pressure chamber in which condition the filling of the mould with liquid resin is effected by sucking the liquid resin into the interior of the mould, the fibre mat stabilised in the pressed state having been produced by stacking individual appropriately shaped cut pieces of mat in a press mould, stoftening the fibre-bonding points, pressing the complete stack of cut pieces of mat to a fraction of its thickness and maintaining the pressure of the press until the fibre-bonding points have again hardened.

Title: Monitoring the presence of human activity in an environment
Inventor: PELKA DAVID G
IPC: G08B21/04
Filed: 1982-05-06
Granted: 1987-04-23
Abstract: A apparatus for automatically de-energizing electrically operable equipment in response to a lack of animal activity, such as human activity, in a specified environment during predetermined time period. The apparatus utilizes a circuit (10) which is designed to detect activity which generates energy in a certain wavelength range and particuiarly, sonic energy. If sound is sensed in the specified environment within the time interval determined by timer (30), a signal is generated to energize or maintain energization of one or more electrical devices (38). Contrarywise, if no sound is detected within the predetermined time interval, there is a resultant de-energization of the electrically operable equipment. A control may be provided to adjust the predetermined time delay period. A control may also be provided for adjusting the sensitivity of the device.

Title: Anti-crossing device for skis
Inventor: SCHWARZ GUNTER
IPC: A63C5/065
Filed: 1983-01-13
Granted: 1986-05-07
Abstract: A ski guard is formed of an elastically tiltable stirrup made of a plastics material with a holding member formed as a part of the stirrup. The holding member maintains the stirrup member in the upright position on a ski by securing its support surface in contact with the upper surface of a base member which attached the stirrup to a ski. When the stirrup tilts or pivots, the support surface on the holding member moves over a boundary surface on the base member overcoming a dead-center position. Movement beyond the dead-center position takes place because of the deflection of a part of the holding member spaced from the support member. Axle journals in spaced axial alignment pivotally mount the stirrup on the base member and permit the location of a large locking element between them for detachably fastening the base member on a fastening plate.

Title: Process for the continuous removal of residual monomers and the post-polymerisation of polyamide 6, and apparatus for carrying it out
Inventor: GERKING LUDER DR ING
IPC: C08G69/46
Filed: 1983-10-07
Granted: 1988-09-08
Abstract: Melts are continuously freed from monomer and are post-polymerised simultaneously under vacuum in a reactor which is a horizontal cylinder containing a driven rotor. This rotor has annular surface discs and/or perforated discs and/or spoked wheels and/or rings which are partly immersed in the melt. Solid lactam is fed into a heated vessel and stirred, together with any additives used (e.g. water, acetic acid, pigments); the vessel has a condenser. A constant speed pump feeds the prepolymer into the bottom of the reactor, from which the final product is also removed by a constant speed pump and supplied to individual spinning points. Reactor contains the rotor, which has a shaft carrying a series of features (26) by struts. These features form a cylindrical cage, whose annular discs dip into the polymer as they rotate. Volatiles escape into the space which is evacuated; they escape through the vent to a condenser. The discs are set at an angle to the end discs; the base also has baffles.

Title: Gas-operated motor with a gas supply apparatus
Inventor: NEUKOMM PETER A DR SC TECHN
IPC: A63H29/16
Filed: 1984-12-27
Granted: 1987-09-17
Abstract: A gas engine with a gas supply device contains a substantially bell-shaped aluminum intermediate housing open on one side and provided with fins on the interior and exterior. A cylinder of the gas engine with good thermal conduction properties and a sleeve accommodating a pressurized gas container having good thermal conduction properties are fastened to this intermediate housing. A gas supply conduit leads from the pressurized gas container to the gas engine. A gas superheater conduit structure is in thermal communication with the intermediate housing and situated at the beginning of the gas supply conduit. The thermal unit formed jointly by the intermediate housing, the cylinder, the sleeve surrounding the pressurized gas container and the gas superheater conduit structure permits operation of the gas engine under all practically arising ambient temperatures without damage to the gas engine, since this thermal unit prevents the gas in the gas engine from condensing back to its fluid or even solid state.

Abstract: The matrix (1,2) of resistive coupling elements (R) links individual elements (E1 to En) of an antenna to the different phase terminals (3 to 6 and 8 to 11) of a phase combiner (7,12). Because of unwanted coupling between the conductive members forming the matrix it has in some circumstances been found impossible to select values of the coupling elements to give a required beam pattern. 
<??>The problem is solved by including phase shifters (21) in alternate lines to the antenna elements. A separate matrix and phase combiner is provided for each beam to be formed.
