Title: Connecting socket for telephone sets and the like
Inventor: KOCH FRITZ EDUARD
IPC: H01R11/05
Filed: 1981-04-08
Abstract: The invention relates to a connecting socket for telephone sets and the like, which has connecting terminals for the supply leads and plug tongues for the plug-in connectors of the apparatus cord. In the case of known (for example 4-pole or 7-pole) connecting sockets of this type, the connecting terminals and plug tongues of the various connecting poles and plug poles are constructed as relatively complicated stamped parts, which are in each case integral, which necessitates a high tool and manufacturing cost. In order to be able to manufacture the contact parts considerably more economically, common connecting terminals (2) and different contacts (4, 5, 6, 7 and 8), which are provided with plug tongues (3), are used, according to the invention, for the various connecting poles and plug poles. The contacts (4, 5, 6, 7 and 8) are attached to the connecting terminals (2) in a particularly simple manner by means of bracket flaps (11). The connecting terminals (2) are designed to be connected to the supply leads by soldering, screwing and without the insulation being stripped off. <IMAGE>

Title: Device for scaffoldings with raisable and lowerable working platform
Inventor: HOPPE LOTHAR
IPC: B66B5/26
Filed: 1981-04-10
Abstract: The invention relates to a device for raising and lowering a working platform which is arranged between two tubular steel towers and has an associated safety device. The aim of the invention is to make it possible to carry out work on roof or facades without using complex sheet-like or three-dimensional scaffoldings. The object was therefore to provide a device which permits uncomplicated raising and lowering of the working platform and, at the same time, prevents the latter from falling downwards. This has been achieved in that the working platform is arranged between four guide rails, provided with cutouts, and is connected, on both sides, to the guide rails via a lifting mechanism and a suspension means, and in that a bearing member is arranged on both sides of the working platform, with the aid of which member the working platform is positioned on the tubular steel towers. On the bearing member there are arranged drop latches (Fig. 3) which prevent the working platform from falling downwards in that, when the chain of the lifting mechanism fails, they latch into the cutouts of the guide rails. The invention can be used, in particular, for repair or reconstruction work on building facades. <IMAGE>

Patent DE-3118589-A1 (DE)
Title: Adjusting device for the double-stroke rate of the stroke movement on gear-grinding machines
Inventor: ANKER DIETMAR DIPL ING
IPC: B23F5/02
Filed: 1981-05-11
Abstract: The invention relates to an adjusting device for the double-stroke rate of the stroke movement on gear-grinding machines, in which a stroke movement is produced by a crank mechanism, the stroke length can be set by changing the crank radius, and the tool slide performing the stroke movement is pivotable in accordance with the helix angle to be produced. The purpose of the invention, by setting a maximum permissible double-stroke rate, is to guarantee a high work productivity of the gear-grinding machines. The object here is to automatically set the maximum permissible double-stroke rate from the loading of the crank mechanism or the maximum permissible double-stroke rate corresponding to the required quality of the tooth system. This is achieved in that a first signal transmitter, which can be influenced only during an actual change in the stroke length, delivers a signal proportional to the stroke length, that a second signal transmitter delivers a signal proportional to the value of the helix angle, that both signals are processed in a computer unit, and that its output signal can be modified by an input value suitable for the quality and can be fed to an actuating unit for controlling the drive motor for the stroke movement. <IMAGE>
Patent DE-3123713-A1 (DE)
Title: Casting or vulcanising mould
Inventor: STEINBORN EWALD
IPC: B29C33/10
Filed: 1981-06-15
Abstract: Casting or vulcanising moulds for rubber and plastic articles always have a greater or lesser number of venting bores, through which the air present inside the mould can flow away to the outside atmosphere when the moulding operation is initiated. In order to prevent on the other hand the casting composition or the rubber compound penetrating into the venting bores with the undesired formation of flash, according to the invention pins having constricted secondary bores running at an oblique angle from a comparatively wide central blind bore are fitted in widenings of the venting bores facing the mould cavity. The novel form and arrangement of the bores in the pins ensure adequate venting and at the same time extensive avoidance of flash.

Title: Drive for magnetic-tape apparatuses or similar apparatuses which are operated at more than one speed
Inventor: RAMOLD JOHANN
IPC: G11B15/44
Filed: 1981-09-21
Abstract: Such apparatuses usually have a drive motor with upstream switching gear, by which corresponding speeds can be selected. According to the invention, for each of the intended speeds there is a separate motor (2, 3; 22-24) with a predetermined rotational speed. The motors (2, 3; 22-24), connected one behind the other, are in operative connection by means of belt pulleys (7, 9) and associated belts (8, 27, 31). If there are a plurality of motors (2, 3; 22-24) connected one behind the other, the motor (2, 22, 23) for the higher speed has a freewheel (16, 26, 40). In particular when switching the drive from a faster speed to a slower speed, the motor (2, 22, 23) for the higher speed may serve as a brake once it has been switched off, thereby reducing the switching time considerably. <IMAGE>

Title: Pressure booster for a fuel injection system
Inventor: STEINWART JOHANNES DIPL ING
IPC: F02M59/32
Filed: 1981-10-20
Abstract: A pressure booster for a fuel injection system has a control piston, the larger end face of which defines a first working chamber, connectable to the injection pump, and the smaller end face of which defines a second working chamber, connectable to the injection nozzle. The stepped piston comprises a first piston section of larger diameter and a second piston section of smaller diameter. A first spring tries to force the first piston section into the first working chamber and a second spring, which is weaker than the first spring, tries to hold the second piston section against the first piston section, thereby covering the through-holes in the first piston section. The second spring is supported on the first piston section and therefore moves with the first piston section so that a very short spring can be used.

Title: Automatic exposure control device for a camera having light metering through the lens
Inventor: YAMASAKI MASAFUMI
IPC: G03B7/099
Filed: 1981-12-04
Abstract: The exposure control device for a TTL camera produces a differential voltage between a light meter value which is obtained from the fixed reflection only from a surface region of the first shutter blind at the beginning of its motion, and a light meter value which varies during its movement. The differential voltage is applied to the base of a transistor which acts as a logarithmically expanding circuit and the varying light meter value is simultaneously applied to its emitter. The logarithmically expanding circuit thus produces a constant output current until the shutter opening, whereas subsequently the voltage applied to the base is kept constant so that the output current of the logarithmically expanding circuit varies in correspondence with the brightness of the object to be photographed.
Patent DE-3151625-A1 (DE)
Title: Frequency converter for controlling asynchronous motors, especially for use in automatic screwdrivers
Inventor: MAYER EBERHARD DIPL ING DR
IPC: H02P23/00
Filed: 1981-12-28
Abstract: In order to achieve precise results with automatic screwdrivers which are driven by an asynchronous motor, the motor must be stopped as quickly as possible on reaching the desired torque. The short desired braking time of approximately 50 milliseconds can be achieved only if the braking process is controlled optimally. To this end, on the one hand it is necessary to take into account the excitation of the armature before the start of the braking process and, on the other hand, it is necessary to match the supply frequency of the motor such that the maximum possible torque is applied throughout the braking process, because the conventional methods of direct-current or opposing-field braking are no longer adequate. The desired characteristics are achieved using a frequency converter which tracks the phase sequence in a counter and, in the event of a braking command, in each case calls up the braking command matching the present conducting phase, from a memory. The operating frequency during the braking process must be optimally matched to the mechanical time constants of the drive via a delay element and a voltage/frequency converter.
