Title: Apparatus for swinging up and lowering the sweeper of a skittle-setting installation
Inventor: SCHMID AUGUST
IPC: A63D5/08
Filed: 1982-05-10
Abstract: In skittle-setting installations, the sweeper for removing the skittles from the skittle alley is moved backwards and forwards along rails and is raised at the front end of its movement path. In order to avoid damage by balls bowled when the sweeper is still in the lowered position, the rocker (8) accommodating the sweeper pin (21) is supported by a deflectable supporting lever (4, 5). In the event of excess loading, the two supporting lever parts (4, 5) bend about the joint (13) in the direction of the arrow (C) and thus release the rocker (8). This swings about the bolt (9) and releases the pin (21). As a result, damage to the sweeper by balls bowled in error can be avoided. <IMAGE>

Patent DE-3315268-A1 (DE)
Title: Method for defining the time duration of signals to be transmitted or received on connection lines in telecommunications switching systems, in particular telephone switching systems
Inventor: HERGER GERHARD
IPC: H04Q3/00
Filed: 1983-04-27
Abstract: In the method according to the invention, the time duration of a signal to be transmitted or received on a connection line is defined with the aid of a timer whose expiry period is defined by time information entered in a memory assigned to the connection line concerned. When a signal is transmitted, the time information entered in the memory directly identifies the expiry period of the timer and thus the time duration of the signal to be transmitted. When a signal is received, the timer is initially set to the shortest possible duration of this signal. It is then established whether the signal was already ended or not when the timer expired. If the signal continues, new time information is entered in the memory and the timer is restarted. The time information present in the memory at the end of a signal indicates the category to which the signal belongs.
Patent DE-3317891-A1 (DE)
Title: Torque wrench
Inventor: TURCK WERNER DIPL ING
IPC: B25B23/143

IPC: G07F11/22
Filed: 1984-01-18
Abstract: In a vending machine having a plurality of product compartments for stacks of cuboid product packs, each product compartment 4 is assigned a dispensing device 6. The dispensing devices 6 are located one above the other and lead into a common fall shaft 38. To achieve a simple extraction of the products and a protection of the fall shaft, a blocking flap 40 is arranged between the lowest dispensing device 6 and the extraction compartment 41. The blocking flap 40 is actuated by an electric motor 54. A product pack falls onto the blocking flap 40 in the closed position of the latter. In the open position of the blocking flap, the product pack slips onto the bottom 55 of the extraction compartment 41. During the transition from the open position into the closed position, the blocking flap 40 pushes the product pack a little way out of the extraction compartment 41. <IMAGE>

Patent DE-3417836-A1 (DE)
Title: Flame glow plug
Inventor: SCHULZ DIETER
IPC: F02N19/06
Filed: 1984-05-14
Abstract: Flame glow plugs are used for the ignition of low and/or relatively high boiling fuels in heating appliances and as starting aids for engines. The object of the invention is to design the fuel connection appropriately so that the draining off of unavoidable air bubbles is possible and forced feeding of the fuel to the periphery of the vaporisation and ignition area of the flame glow plug is ensured. This is achieved in that a pipe bend is connected to diametrically arranged inlets which end in an annular gap. On the other side the annular gap is connected by duct bores to the ignition chamber. The duct bores terminate on the periphery of the tapered end of the glow rod or of the insulating body. <IMAGE>
