Title: Hydrostatic low speed drive for construction vehicle - with fail-safe clutch and permanently engaged gears
Inventor: TUKSA EMMERICH ING
IPC: B60K17/28
Filed: 1973-11-12
Abstract: Some types of construction vehicle have a hydraulic auxiliary drive in which a hydraulic motor is coupled to the wheel shafts by a set of gear wheels, to provide a low speed drive. Difficulties in engaging the gears are overcome by using a constant mesh assembly with the drive to the wheel shaft taken through a special over run clutch which allows the wheel shaft to rotate faster than the hydraulic drive, without damaging the drive. This enables the vehicle to be driven using its main drive. For reverse travel on the main drive a fail-safe facility removes the hydraulic pressure from the hydraulic motor before engaging the drive.

Title: Double spiral conductor esp. for electric watch - made by coating narrow side of spiral spring by etching
Inventor: BARTH MANFRED
IPC: G04C3/06
Filed: 1974-04-11
Abstract: A method of applying a thin electrical conductor onto one face of an electrically conducting spiral spring, with an insulating layer between them, esp. for an electric clock or watch is as follows: an electrically conducting sheet is applied to a narrow edge face of the turns of the spiral spring with adhesive; the conducting sheet is then etched away using an agent which attacks it much more rapidly than the spiral spring matl. and adhesive, or which does not attack the latter at all. The spring characteristic is hardly modified at all because the amt. of matl. added is extremely small. Nevertheless, the cross-sectional area of the applied conductor is quite sufficient for the low current involved in electric clocks or watches.

Title: Several-phase synchronous machine - has at least four poles and two line sections for phase windings
Inventor: WEIS MICHAEL DR
IPC: H02H7/06
Filed: 1974-05-31
Abstract: The several-phase synchronous machine has at least four poles. The phase windings consist of at least two line sections each switched to rectifier bridges connected in parallel on the d.c. side. The terminal wheel of the line sections has the same number of d.c. excited exciting pole windings as one of the number of terminals of the synchronous machine. Each exciting pole winding (F1 to F4) has voltage limiting means switched in parallel. This arrangement prevents damage to the field winding. The limiting means can be voltage-dependent resistances with non-lineal characteristics. When the field windings are fed in parallel excess voltages are already suppressed by exciting current flow.

Title: Extruded or drawn aluminium waveguide - has irregular wall thickness distributed to allow deformation whilst maintaining internal symmetry
IPC: H01B11/18
Filed: 1974-07-03
Abstract: The extruded or drawn aluminium waveguide has a cross section symmetrical about its shorter and longer axes, but with an irregular wall thickness. The ratio of the wall maximum thickness (e) to its minimum thickness (d) in the larger wall and the distance (f) between wall thickness maxima are so chosen that, when the waveguide is bent about its broader face, the deformation in cross section of its cavity is such that its shrinkage or reduction in size remains symmetrical. The wall thickness (c) of the sides of the waveguide is sufficient to resist deformation. The waveguide can thus be distorted without significantly affecting its electric properties.

Title: Film with sound track and picture together - operates without usual displacement by temporary storage in pulse or digital form
Inventor: SCHICKEDANZ WILLI DIPL ING
IPC: G03B31/02
Filed: 1974-11-23
Abstract: To simplify editing, cine film sound is recorded alongside the picture not displaced forward as is usual. The film movement through the camera gate is too jerky for sound at that moment, so the sound is stored temporarily using pulse or digital storage with conversion from analogue, and a pulse or digital sound track. This is read out in the projector, and again stored temporarily, to delay reproduction until the frame has reached the projector gate. The analogue-to-pulse/digital conversion allows the sound heads to be put nearer the film gate, as irregular film movement, producing irregular pulse/digit repetition rate, can be corrected electronically. This reduces the amount of space required.
