Title: Knocking detector
Inventor: ENOSHIMA TOSHIO
IPC: F02P5/152
Filed: 1981-02-18
Abstract: Either before or after rectification, a comparator (126) compares a signal which is received from the oscillation signal which specifies the oscillations of an externally ignited internal-combustion engine and has passed through a signal-passing filter (132), with a reference level signal from a circuit (124) which forms the latter and is provided for generating a knocking signal which specifies the occurrence and the intensity of knocking, when the strength of the first signal is greater than that of the last. The circuit (124) forming the reference level signal effects rectification and smoothing of the oscillation signal, in order to generate a rectified, smooth signal, and has a first amplifier circuit (130) which amplifies the rectified, smoothed signal in order to generate the previously mentioned reference level signal. If the speed of the internal-combustion engine is greater than a specific value, a control circuit (138) generates for the speed of the internal-combustion engine a driver signal to which a changeover circuit (136) responds by switching over the gain of at least one of the signal-passing filter (132) and the circuit (124) forming the reference level signal from one value to another, as a result of which knocking which may occur in the overall range of the higher and lower speeds of the internal-combustion engine is reliably detected in order to be used in controlling the ignition point of the externally ignited internal-combustion engine. <IMAGE>

Title: Sealing system for a rotary evaporator
Inventor: ZELLWEGER ADOLF
IPC: B01L3/00
Filed: 1981-04-09
Abstract: A rotary evaporator has a flask (23) which is rotated about its axis by a drive apparatus (25). A vapour passage pipe (15) conducts the vapour from the rotating flask (23) through the drive apparatus (25) to the fixed condenser (3). A shaft seal (6) is arranged between the fixed and movable vapour-conducting parts. This shaft seal is held by an intermediate piece (5) which is arranged on the condenser-side end (24) of the vapour-conduction tube. For additional protection of the shaft seal from the medium, the end (24) of the vapour passage tube moves in an annular-shaped channel (10) in the intermediate piece (5). As a result, in reflux distillation, damming of the distillate flowing back is simultaneously avoided. The sealing system is simple in construction and the shaft seal is readily accessible from the condenser side. Teflon coating of metal parts of the drive apparatus (25) is not necessary. <IMAGE>

Title: Roller blind for screening glass surfaces
Inventor: WILLE RUDOLF
IPC: E06B9/386
Filed: 1981-04-11
Abstract: The invention relates to a roller blind for screening glass surfaces, in particular in the case of windows of buildings, which blind is essentially composed of mutually parallel, strip-shaped, adjustable or non-adjustable elements which are displaceably guided and consist of translucent material. In the case of said roller blind, the elements (1) are each designed such that they give rise to a reaction which has the effect of darkening or brightening the existing light intensity. In the event of changing light conditions outside, the brightness of a room screened by said roller blind remains essentially constant without further assistance and without additional means. Objects located in the screened room are prevented from being damaged by the effect of light which is too strong. Furthermore, heat losses in cold weather are reduced by the roller blind which, owing to its translucent character, can remain all the time in front of a window of a building. <IMAGE>

Title: Retractor device, locking in an emergency, for a restraining belt for a vehicle occupant
Inventor: TAKADA JUICHIRO
IPC: B60R22/405
Filed: 1981-06-02
Abstract: A retractor device, locking in an emergency, for a restraining belt for a vehicle occupant comprises a locking mechanism with an inner disc which is received on the reel shaft and which is movable in the axial direction towards a side part of the frame, in which the reel is mounted, and away from the said frame, an inertia spring which normally keeps the inner disc in an outer position, in which the mechanism is unlocked, and an outer disc held on the shaft against movement axially outwards away from the frame. One of the two discs is rotatable relative to the shaft, whereas the other rotates together with the shaft, and mutually cooperating cam members and counter cam members on the inner disc and the outer disc respectively displace the inner disc towards the frame in response to an abrupt pull-out of the belt and bring mutually cooperating locking detent teeth into engagement on the inner disc and on the frame, in order to detain the inner disc against rotation. The reel shaft is interlocked with the inner disc by means of a flange arranged on the shaft and having noses which fit into interlocking slots in the inner disc. A third set of detent teeth on the circumference of the rotatable disc can be brought into engagement with the pawl of a device responding to inertia forces and initiates the same locking as a rapid pull-out of the belt. <IMAGE>

Title: Method of welding different thicknesses of material
Inventor: KRETZSCHMAR HEINZ DIPL ING
IPC: B23K9/00
Filed: 1981-10-06
Abstract: The invention achieves the object of developing a method of welding different thicknesses of material, preferably hollow bodies to solid bodies of similar or dissimilar materials, in particular a knife handle to a knife blade. Here, means adaptable to automation are proposed which guarantee the quality features demanded in the case of these welded joints. The invention essentially consists in a protective thermal shield being introduced between the components to be joined in such a way that the energy supplied from a heat source is split up into primary and secondary energy. During a first rotation of the components, pre-heating with partial melting of the hollow-like component with the protective thermal shield takes place. During the subsequent second rotation, the protective thermal shield is completely remelted and finally produces a sound weld formation while using the cushion effect.

Title: Variable length adjusting rod
Inventor: KINDEL GEORG
IPC: B60K26/04
Filed: 1982-01-29
Abstract: The invention relates to a variable length adjusting rod having a tubular threaded sleeve which is provided with a thread at both ends, and threaded rods which are screwed into the threaded sleeve on both sides, can be adjusted relative to one another in the axial direction and have hinge eyes fitted to their ends. In the case of these adjusting rods, which are used for example for aligning platforms, the requirement sometimes exists for it not to be possible to vary the angular position between the hinge eyes during adjustment. Previous expensive and complex structures are in consequence intended to become simpler, cheaper, smaller and lighter, in that the inner ends of the threaded rods are constructed to form mutually touching sliding surfaces which are on parallel axes, prevent relative rotation and correspond to one another. The axial extent of the sliding surfaces in conjunction with the threads used determines the adjustment range of the adjusting rod.
