Title: Tilting window wing opening extending mechanism - has elastic radial sections on protective spring round sliding lug
Inventor: OKON WINFRIED
IPC: E05C17/28
Filed: 1979-05-15
Abstract: A rod(s) has one end hinged to the fixed frame, and the other end displaceably connected to the wing, by a sliding lug engaging a guide slot, in provision for extending tilting, or tilting and turning, wings on windows or doors. The mechanism incorporates a profile spring (22), enclosing the periphery of the lug (20) at the level of the guide slot (16). This has radially protruding, elastically resilient sections (23, 24). It can be C-shaped, with ends of the C, arms supported on the lug periphery. The slot's open width may vary. This prevents the wing from clattering in the tilt position, and also prevents sliding lug fracture.

Title: Forklift truck multiple telescopic mast - has two rams operated singly or in parallel over telescoping range
Inventor: KLINGBERG ALFRED ING GRAD
IPC: B66F9/08
Filed: 1979-07-26
Abstract: The lifting mast has a stationary section and an extending one with a load support guided in it and lifted by a chain. One ram has a cylinder length half that of the mast rails between masts and load support, and another a cylinder length equal to the mast length. The chain is reeved from the load support over a guide with rails for the latter and another guide on the extending piston rod of the first ram to the bottom of the latter, and the ram cylinders are connected together, their pistons extending in succession as the result of the different loads. The piston rod of the second ram is coupled to an extending mast section. The load support is moved for most of the length of its mast rail by the first ram. For the remainder of this length and for simultaneous telescoping of one or more mast sections for a correspondingly small amount the first ram is operated together with the second one in parallel.
Patent DE-2932850-A1 (DE)
Inventor: BUCHER HEINZ
IPC: A61H33/02
Filed: 1979-08-14
Abstract: The invention relates to an elongate bubble grid (10) for an underwater massaging device comprising several bubbling zones (A, B, C, D) which are subdivided in the longitudinal direction and can be controlled, individually and/or in groups, with switching members (15) by means of a manifold (11). In the prior art, individual control of the bubbling zones requires a separate manifold. Besides greater expenditure this necessitates cumbersome operation of the switching members of the manifold. These disadvantages are remedied in that the manifold (11) is located at the foot end of the bubble grid (10) and in that the bubbling zone (A) adjoining the manifold (11) is directly connected thereto, and in that the following bubbling zones (B, C, D) are connected via continuous feed channels (24, 25, 34, 35, 44) through the upstream bubbling zones to the manifold (11). <IMAGE>

Abstract: PCT No. PCT/EP80/00038 Sec. 371 Date Jun. 4, 1981 Sec. 102(e) Date Jan. 27, 1981 PCT Filed Jun. 28, 1980 PCT Pub. No. WO81/01085 PCT Pub. Date Apr. 16, 1981.An electronic control and regulating system for AC-operated appliances, especially universal motors and with symmetrical phase control. The control circuit includes among other things an inductive current-voltage converter 9, the primary side 8 of which is connected to the load current circuit and in which, in addition to the converter function, the inductivity of the secondary winding 10 is used and becomes a component of a resonant circuit 20 which is tuned approximately to the frequency of the AC voltage source. The feedback variable of the control system is formed by the resonant circuit voltage, i.e. the resonant circuit impedance, which depends not only on the magnitude of the load current but also on the phase angle of the load current. This quasi-resonance effect makes possible a direct influence of the trigger circuit which consists customarily of a trigger capacitor 13, a load resistor 11 and a trigger diode 15 and is possible without excessive use of additional circuit elements.

Title: >>Method and device (interface circuit) for data transmission<<
Inventor: SCHUHWERK ANTON
IPC: H04L25/02
Filed: 1981-02-27
Abstract: A system is proposed for transmission and back transmission of data, preferably within closed line networks, in which a transmitter and a number of receivers (terminals) are in each case provided which are connected to the transmitter in a closed current loop. For data transmission, the transmitter generates a pulsed constant current and, for voltage limitation and stabilisation, makes use of a control circuit in the form of a sample-and-hold circuit which draws surplus constant current from the line when the closed line loop is interrupted by one or more of the connected terminals. An undesirable, excessively high voltage rise is thereby prevented and automatic line balancing is achieved independently of prevailing conditions on the line.

Title: Device for checking used pallets stacked in blocks for individual serviceability
IPC: G01M99/00
Filed: 1981-03-20
Abstract: The invention relates to a device for checking used pallets stacked in blocks for individual serviceability. Due to transport and to the fork-lift truck, the pallets, which consist of wood, suffer damage which can palpably disturb the automatically proceeding working cycle of loading and unloading the pallets. It is therefore necessary before each renewed use of used pallets to check the latter for their individual serviceability, in order to spot and weed out in good time damaged pallets having lacking or projecting parts. The object of the invention is to eliminate the disadvantageous checking work directed only at one individual pallet, which cannot be managed without heavy manual work at the input and at the output of a checking device. This object is achieved according to the invention by a frame having horizontal guide rails on which there is arranged capable of being moved by a motor drive a gripper which can be moved vertically by machine and has plug-in mandrels, which can be extended hydraulically in opposite directions and horizontally, for laterally gripping and supporting a pallet as well as a plunger, which can be hydraulically extended in the same direction and vertically, for loading a pallet with checking-pressure on the top side, and by a checking station which is arranged in the frame and has a checking-pressure loading device on the underside of the pallet.
