Title: Skid preventive tyre spike - has vertical conical sprung head to causing damage to road surfaces
Inventor: BRENNER FRANZ
IPC: B60C11/16
Filed: 1973-10-16
Abstract: The spike consists of an outer casing and an inner fixed hard metal body. The outer casing is cylindrical with a hollow tapered head facing into the tyre body, the end of the head thus being cylindrical with an annular bearing surface. When running on ice free roads, the casing is pushed below the surface of the tread, the body of the tyre being forced up inside the annular bearing surface to provide a cushioning effect. The inner hard metal body is provided with longitudinal cooling ribs and has a cross shaped end face.
Patent DE-2360643-A1 (DE)
Title: Control circuit for car wash - with continuously variable horizontal and vertical speed of portal to improve cleaning of body edges
Inventor: KUELMER ULRICH VON
IPC: B60S3/06
Filed: 1973-12-05
Abstract: The horizontal brush of the car wash is mounted on vertically adjustable supports in the travelling wash portal. The portal horizontal speed is controlled w.r.t. the reaction force of the horizontal brush with the body, so that it slows for the end faces of the body. The vertical speed of the brush supports are controlled in relation to the horizontal speed so that a smooth changeover is achieved when the brush moves over the edges of the vehicle. This prevents the brush from jumping over the edges and missing dirty sections. The effect is improved by the continuous speed control which is an improvement on the stop-start system of other car washes.
Patent DE-2361620-A1 (DE)
Title: Treatment of waste water, esp from dye houses - with bulk of surfactants being removed as foam and mixed after standing with recycled coagulated sludge
Inventor: SASANO TOSHIO
IPC: C02F11/12
Filed: 1973-12-11
Abstract: For its purificn. dye house waste water contg. pigments and a large amt. of surfactants is treated by first being agitated thoroughly with compressed air to build up a foam which overflows with the bulk of the surfactants into a settling tank. The liq. freed from the foam is treated with coagulating and pH-adjusting agents and clarified, the sedimented sludge then being mixed with the foam returned to liq. form and vigorously agitated to exploit its residual coagulant qualities. The process is repeated, the coagulated sludge being continuously recycled into liq. derived from the foam, until its value is completely exhausted.

Title: Automatic folding of paper bag edges and sealing - cylinder operated fingers fold over edges and bag is moved to output station for sealing
IPC: B65G65/00
Filed: 1974-06-21
Abstract: A fully mechanised machine receives paper bags full of loose materials and seals by forming four folds that are joined together. The bag is located vertically in a carrier (11) mounted on a table (4) that can be moved horizontally by a cylinder (3). The first two folds of the top edge of the bag are made by pivoted side fingers that are powered by cylinders (26). A second cylinder then moves sideways to make the third fold. To form the final fold the bag is moved horizontally on the table (4) under a guide plate (16) that folds the free edge over. The horizontal feed continues until the bag is located under a cylinder powered joining tool (28) to provide a seal. A programmer (6) controls the sequence of operation.

Title: PBX with call redirection circuit common to two extensions - diverts call from non-answering extension to second extension
Inventor: VANDERBUSSE ROBERT
IPC: H04M3/54

Title: Inlet for brake chamber vent - has internal flow deflecting plates to provide zig zag flow path to exclude dirt
Inventor: INGENLATH NORBERT DIPL ING
IPC: B60T17/08
Filed: 1974-06-25
Abstract: The tube is used for venting of brake cylinders, especially for secondary chambers in brake systems. The secondary chamber vol. is increased or reduced when a piston or a diaphragm is moved in it. The venting tube ensures free movement for the piston or diaphragm by facilitating atmospheric air flow. The tube prevents the entry of dirt or moisture, which ensures longer life for the brake actuating mechanism. The tube has internal flow deflecting plates which form part of the wall and project into the tube bore beyond the tube centre line. The flow assumes a zig-zag course. the deflecting plates can project at right angles to the walls or they can slope towards the inlet. A vent tube can also be tapered so that its free end is narrower than the end at which it is anchored on the chamber wall.

Title: Drying of animal excrement with silicic acid - eliminating drying appts for use as fertiliser and fodder for ruminants
Inventor: KIEFER HEINRICH DR DR
IPC: A23K10/26
Filed: 1975-03-21
Abstract: Silicic acid, mixtures and cpds. contg. silicic acid and silica gel are used to dry animal excrement, which is to be used as fertilizer or as fodder or fodder components for ruminants, optionally as an aid to thermal drying and to improvement of the storage capacity of animal excrement. The silicic acid is mixed with the excrement, pref. chicken excrement, in a quantity adapted to the water content of the excrement and its application, and acts by binding the water in the excrement so that the latter dries in air and can be converted immediately to a dispersible form. Water binding also prevent microbic fermentation of the excrement and release of organic substances and odours. This method eliminates the need for conventional drying appts., requiring only mixing and metering means for adding the silicic acid.
