Patent DE-1959583-A1 (DE)
Title: Synthetic plastics heat deforming machine - loading and unloading unit
Inventor: GALLI ALBERTO
IPC: B65H5/10
Filed: 1969-11-27
Abstract: The unit has a first remover, with devices to remove a treated foil from the treatment position of the machine, and to transfer it into a waiting position. A second remover has devices to remove a foil to be treated from a storage. Further units alternately move the second remover between teh storage and the treatment position. When it is in the latter position, further units are operated, to free both foils from the remover, so that the foil to be treated is deposited in the treatment position, while the treated foil is positioned on units on the second remover, to transport them away.

Patent DE-2019279-A1 (DE)
Title: Tiered baking oven
Inventor: FISCHER GEORG
IPC: A21B1/10
Filed: 1970-04-22
Abstract: Tiered baking oven has top, centre and bottom radiators with gas chambers and adjoining oil-heated channels. The channels interconnect and are fitted to the radiators so as to face into the baking space, preferably designed in trapezoidal form so that the channel base faces the radiator and the radiation surfaces point into the baking space. A pump forces the oil through the system, with an expansion tank. Heating is uniform due to transfer of heat from channels to chambers, thus dispensing with special heaters or baffles or narrowed points in the chambers. The oil is heated up in the radiator, thus dispensing with heat exchanger fittings.

Title: Laying extrusion spun fibre strand material - with two braking units in its path, travelling without tension between units
Inventor: SCHIPPERS HEINZ DIPL-ING
IPC: D01D7/00
Filed: 1972-12-15
Abstract: The extrusion spun fibre material, travelling at speeds around 3000m/min is passed to the first braking unit where it enters a passage defined by two conveyors moving slower than fibre travel to allow it to build up in the base of the passage. It then passes without tension to a second, similar unit, to drop at virtually zero speed into the silver can. The purpose is to control the fibre travel, without disturbing the molecular orientation, and without allowing it to tangle.

Patent DE-2343044-A1 (DE)
Title: Load-limiting monitor system for AC network supplying welders - ensures efficient use of network by determining total power before switch-on
Inventor: VOLLING GUENTER
IPC: H02J3/14
Filed: 1973-08-25
Abstract: The load limiting monitor system for a.c. networks supplying electric welding equipment interrogates each welding machine, or group of welding machines, before they are switched on, to determine whether the additional power consumed by them will overload the a.c. network when added to the power already being consumed by other welding machines already in operation. Each welding machine is interrogated regardless of whether the summed power load obtained from a previous welding machine exceeds or lies below a given total power load. If, after a given time, that welding machine power which is causing the summed power load to exceed the total permissible load still does not allow that welding machine to be switched in without overloading the network, the interrogation process is terminated. The system enables the a.c. network to be used more efficiently.
Patent DE-2346417-A1 (DE)
Title: Compound laminated ski construction - uses contoured complementary material saving inserts without loss of strength etc.
Inventor: SCHREINER FRANZ DIPL ING
IPC: A63C5/12
Filed: 1973-09-14
Abstract: The construction method is designed to make economies in the use of the more expensive laminate materials without reducing the strength or quality of the finished ski. This is achieved by varying the thickness of the inserts along their length according to the stresses normally experienced at various points. The inserts are made up from several short parts which are cut in shapes to reduce wastage or offcuts. The joints are formed by V shaped profiles. Two laminates are placed side by side at the same level. Preferably the total cross section of the laminates in the central zone of the skis is smaller than at the ends.

Title: Variable function emitter - outputs values depending on series of equidistant input values
Inventor: HOVES HANS
IPC: G06F1/03
Filed: 1973-09-28
Abstract: The function emitter, for use chiefly in automation techniques and data processing, outputs values, according to a function, depending on a number of variable input values. A block of shift registers has each shift register of 10 bit length the first of which is used to transmit values to the output register. The registers are controlled through a stroke impulse lead and all the shift registers are switched as cyclic registers. Input to the registers is from a conventional device which writes in serially 10 initial values in an 8 bit code. A counter counts the number of places by which the values in the register block have moved and its status is compared with that of an input register in an equivalence circuit.

Title: Braking of tape reel in cassette tape recorder - involves using assembly holding brake shoe for each drive plate
Inventor: HERLETH KARL
IPC: G11B15/22
Filed: 1973-09-28

Title: Self-locking differential gear for vehicles - has locking clutches and release clutches within the gear housing
Inventor: ALTMANN WERNER
IPC: F16H48/22

Abstract: The frictional differential locking clutches are fitted under preload between the differential output gears and the differential planetary gear carrier, and release clutches are fitted between the output gears and the drive shafts the release clutches acting in the opposite direction to the locking clutches. Each release clutch is so arranged that under any drive torque the release forces are at least approximately the same as or smaller than the axial pressure on the output gear arising from the engagement between planetary and output gears. Each friction clutch is so arranged that the axial pressure on the clutch assembly produces a greater torque on the clutch plates than the corresponding torque on the output gear.

Title: Fixing tubes to heat exchanger end plates - involves using adjustable hydraulic deforming force applied to probe sealed into plate
Inventor: KRIPS HERBERT
IPC: B21D26/02
Filed: 1974-01-03
Abstract: The tube end is positioned in the hole in the steel plate. A probe is inserted into the tube leaving an annular space between probe and tube, the space being sealed by sealing rings positioned approximately at the limits of the plate. Hydraulic pressure is introduced to the space by internal passages in the probe and the tube is deformed to fit the hole in the plate. An extraction-resistant joint is made by using a pre-machined recess in the bore of the hole. The bore through the plate may have regions of slightly increased diameter into which the tube expands to help to secure it against pulling out in service.

Title: Latent charge image production - on an electrophotographic plate with an external insulating layer and high sensitivity photo-conducting layer
Inventor: NARITA KINICHIRO
IPC: G03G5/043
Filed: 1974-02-28
Abstract: In the production of a latent electrostatic image on an electrophographic plate, consisting of an electrically conducting substrate supporting a photoconductive layer, which in turn carries an insulating layer, the plate is uniformly charged-up to a potential at a first polarity, is uniformly exposed to light and simultaneously exposed in imagewise manner and then uniformly charged-up. Pref. the charging is carried out with exposure to light, controlled by its intensity. The use of two stages of electrostatic charging gives a lower potential on the corona discharge unit and therefore greater safety in carrying out the process. The photoconducting layer is protected by the insulating layer and hysteresis is markedly reduced.
