Title: Speed change gearing with rotatable selector shaft - has semicircular cams whose flats locate shaft in position with foot pedal to withdraw cam followers
Inventor: STIEVE KONRAD
IPC: F16H61/02
Filed: 1976-02-17
Abstract: The speed gearing has a rotatable selector shaft (2) provided with angularly off-set half-round cams (1) which act on spring-loaded followers (4) which in turn act to establish driving connection between respective gear trains. The selector shaft is held in a selected position by engagement between the follower and the flat of the associated cam. A foot pedal (6) is arranged for withdrawal of the followers from the cams so that the follower for the time being in gear can be withdrawn to relieve the load on the flat of its associated cam. This allows the shaft to be rotated for selection of another gear.

Title: Four wire carrier frequency system - converts four specified CCITT quaternary groups into frequency of fundamental quinternary group using given carrier
Inventor: MAERKL GEORG DIPL ING
IPC: H04J1/04
Filed: 1976-05-13
Abstract: The 4-wire carrier-frequency system, for 3600 voice channels with the same frequency plan for the incoming and outgoing bands, can be converted by a carrier into the frequency of the fundamental quinternary group of an 80 MHZ CARRIER system such that when this is switched to another system also using the 80MHz carrier that system's filters can continue to be used.

Title: Determn. of error rate of individual signal steps - includes application of binary signal part and locally generated test signals to error rate measuring device
Inventor: APPELMANN WOLFGANG DIPL ING
IPC: H04L25/04
Filed: 1976-09-24
Abstract: The error rate determn. method relates to multiple step digital signals in a high bit rate digital transmission system. The N-step transmitted signal is converted into N-1 binary signal parts, so that each of them corresponds to a transition between two steps of the multiple step signal. N-1 binary test signals are locally generated. They represent the binary signal parts in a free from error state. A binary signal part corresponding to an examined step transition, and the locally generated test signals corresponding to the other step transitions, are combined and applied to an error rate measuring device. They are compared bit-by-bit by a modulo-2 addition. The decision threshold is set to a specified value.
Patent DE-2649493-A1 (DE)
Title: Sealing tape system for multicore cable joints - has adhesive on both sides of tape and individually removable protection film layers
Inventor: TUSCHY PETER
IPC: H02G15/013
Filed: 1976-10-28
Abstract: The tape finds application where the space between cores is limited, for example where the cable enters a jointing box. The tape is covered with adhesive on both sides. Each side is protected by a sacrifice film (2, 3) which is doubled over so that both ends (22, 32; 23, 33) are accessible from one side, and can be removed by pulling one end. The film is placed round the core (10) to be covered and the free end (22) of the inner film (2) pulled. The film is removed, and then by pulling on the outer film (3) the tape is made to adhere to the core. The stripping process is then repeated by pulling off the outer film (3). The free ends of the tape can then be pressed together (6) to form a joint. When the jointing box gland is then pressed into position the adhesive tape seals onto the gland and onto adjacent cores giving a damp proof construction.

Title: Machine component gap measurement and monitoring device - uses lamp on first component and photodetector on second component with illumination varying with gap
Inventor: BERTHOLD RAINER DIPL PHYS
IPC: G01B11/14
Filed: 1976-11-27

Title: Robot for electric resistance spot welding - using portal fitted with work cylinders carrying welding electrodes
Inventor: POLLMANN WERNER DIPL ING
IPC: B23K11/11
Filed: 1977-01-08
Abstract: Plant for the electric resistance spot welding of sheet metal components and assemblies using welding robots fitted with >=1 multijoint arm carrying >=1 welding electrode. The arm is driven by stored data so a defined sequence of welds is made at exact locations. The workpieces move along a transfer table which carries a portal or a portal system, from which the welding electrodes are suspended; and the portal is used to exert and absorb the pressure applied by the electrodes during spot welding. An indexing mechanism is pref. used to align the portal w.r.t. the welds, esp. by mounting the portal on a template carrying the workpieces; and numerical control is pref. employed to synchronise the motions of the robot arm and to clamp the template. The portal absorbs the welding pressure, e.g. when using two electrodes on the upper side of the workpieces.

Title: Machine tool safety system ensuring use of eye protectors - has holder permitting machine tool operation only when glasses removed
Inventor: STAEGE RUEDIGER
IPC: B23Q5/58
Filed: 1977-03-02
Abstract: Protective industrial glasses (3) used in conjunction with fast operating swarf removing machine tools are so arranged in a movable holder (1) inside a housing (2) that the holder operates a switch (4).
