Title: Lathe chuck operating unit - has control unit to regulate opening stroke level and effect changeover between high and low clamping force
Inventor: JUNKLEWITZ HUGO
IPC: B23B31/30
Filed: 1978-09-02
Abstract: The lathe chuck can be operated in two stages, the changeover from a high to a low value clamping pressure being effected by an automatic control unit. A device is included to regulate the flow of pressurised fluid at the beginning of the chuck opening stroke, and to also regulate the changeover in response to the amount of opening of the chuck. This prevents deformation of the workpiece by excessive force but still provides adequate holding at reduced pressure.

Title: Tube braiding bobbin paths - have structured intersections for continuous paths to reduce wear and noise
Inventor: HILBRIG WERNER
IPC: D04C3/22
Filed: 1978-10-21
Abstract: To braid reinforcing threads, filaments or wire strands round tubes, where there are a number of supply bobbins with sliding feet travelling along intersecting and continuous paths, there are straight crossing sections between the curves. The crossing points so formed give two obtuse and two acute angles at the crossing edges. The straight sections have a length which is no more than the length of the sliding feed. At the straight intersecting sections, the parths have an internal width corresponding to the span of the sliding feet, opening out into the curves. The sliding feed have a basic extended rectangle form with a width-length ratio of 1:5 to 1:8 and up to one-third until half the width of the tapering end sections where they follow a curve corresp. to the path curve along a length corresp. to the sliding feet width. The design reduces wear so that accurate running life is extended, and operating noise levels are reduced.

Title: Countercurrent washing machine with transfer of linen - from compartment to compartment, has adjustable distributors regulating flow and liquor level
Inventor: STEINORT HANS
IPC: D06F31/00
Filed: 1979-03-28
Abstract: The lateral outlets adjustable in size, provided for each of the compartments into which the liquor container and its rotating drum in a countercurrent washing machine are divided, open int a collecting chamber. From this the liquor is transferred from above the fluid level in one compartment to a point below the fluid level in the next. A transfer pipe connects the collecting chamber to a heatable reversed flow chamber below, whilst the transfer pipe and a drain pipe both are branched from a water volume distributor in the collecting chamber. The collecting chamber and the reversed flow chamber are located on adjacent halves of the compartment. The layout achieves optimal adaptation of the conditions of flow from compartment to compartment, and there is easy adjustment both of the flow and of the level of the liquor in the separate compartments.

Title: Dough stretching frame - with lifting beam for handling dough sheet without drying
Inventor: MORGENTHALER EUGEN
IPC: A21C3/02
Filed: 1979-06-05
Abstract: A thin sheet of dough is produced from a rolled strip by clamping the strip edges on two tables and by moving the tables crosswise to stretch the belt to the desired width. A round beam along the centre line under the sheet is lifted up by hooks to let the sheet hang down from it on both sides. This allows the dough sheet produced to be handled without requiring even a partial drying operation. The result is a saving in floor space and in apparatus.

IPC: B60P3/16
Filed: 1979-06-16
Abstract: The concrete mixing and transporting drum mounted on a lorry includes a system of quickly emptying the drum in case of an accident on the road, since the concrete hardens quickly, and if not removed, renders the drum useless. A ring (15) is mounted on the end face (10) of the drum, around the bearing plate (11) so that a cable (14) can be passed around it, to tilt the drum. The ring can be made of steel angle with one face (15) attached to a strengthening plate (13) around the end flange (8) on the drive shaft (7), near the middle of the flange. Alternatively, the strengthening plate rests on the periphery of this flange. In another design, the cable support can be an extension of the flange itself. In a further design, the support can consist of a ring shaped plate bolted onto the flange, projecting from it.

Patent DE-2949208-A1 (DE)
Title: HF outdoor coaxial cable - uses air as part of dielectric and has insulating spacers between inner and outer conductors
Inventor: WICHMANN FRANZ-JOSEF ING GRAD
IPC: H01B11/18
Filed: 1979-12-04
Abstract: The coaxial cable can be used for closed circuit t.v. To reduce the size and cost of the cable, air is used as part of the dielectric, although this tends to seriously reduce the resistance to bending stresses. The outer dielectric sleeve (13) of the cable is formed over the inner conductor (11) on which spacer discs of insulating material (12), are arranged at regular intervals. The sleeve is applied such that, in the gap between spacers (12), its radial thickness (14) is greater than at the support points on the spacers. The greater thickness in the region of the air space increases the stiffness of the cable to bending. It is therefore less prone to collapse the air space when being installed. The sleeve can be applied in one extrusion process, or a thin layer may be applied first followed by a final layer applied by pressure injection forming to fill the hollows between spacers in the thin layer.

The thickness ratio of one of the outer layers to the (II) reservoir layer is ca. 1:2. Reinforcing inserts are provided in the inner layer or between this and an outer layer. The laminate is protected from deterioration, e.g. embrittlement and shrinkage, due to (II) loss.
