Title: Quick release clamps for slotted 'T'-plates - for holding plates in a machine tool or on a setting-up bench
Inventor: WOLLENHAUPT JAKOB
IPC: B23Q3/06
Filed: 1973-05-08
Abstract: The slotted plate (i.e. a T-plate) is held between two clamps, one fixed, the other moving. The moving clamp has an upper part with a slot for a clamping bolt; when the bolt is tightened, the upper part slides down an inclined surface on the lower part of the clamp so that a wedge moves inwards and downwards. The side faces of both the fixed and moving clamps which face the T-plate are wedge-shaped; the wedges are pointed and slightly penetrate the sides of the plate; alternatively, two grooves can be machined in the plate to coincide with the wedges. The upper surfaces of both wedges have a smaller angle with the horizontal than the lower surfaces so that as the clamp tightens the plate is pressed downwards on the bed. Helical compression springs are mounted in the moving clamp so that when the bolt is loosened the upper part of the clamp moves upwards and outwards so that the plate is free.

Title: I.C. engine for pulverised solid fuel - has gasification chamber centrally surrounding compression and combustion chamber
Inventor: NEHLS WALTER
IPC: F02B45/02
Filed: 1973-12-18
Abstract: I.C. engine for powdered solid fuels has a compression, combustion and gasification chambers built onto the cylinders, with incandescent walls during operation. Hot combustion gases gasify the dust, introduced with a gaseous medium, before the opening of the exhaust path, to use the heat. With permanently open connection between the working cylinder and the compression- and combustion-chamber, the separate gasification chamber is not in constant communication, and preferably centrally surrounds the first chamber, with which it is connected by an automatic and/or positively controlled closure element after completion of combustion during the expansion stroke, before the exhaust path is opened, for a time, for passage of hot combustion gases toward the gasification chamber to produce power gas. Because of the excess press. in the first chamber, fuel dust, ash, or residues cannot reach the cylinder via the first chamber. High compression can be obtd.

Title: Sealing device for rock consolidating plastics grouting - includes tensioner arm, bored probe, and foam plastics recessed end plug
Inventor: BRANDSTETTER FRIEDRICH
IPC: E21D20/02
Filed: 1974-03-04

Sealing is effected by means of a mushroom shaped plug made from foamed plastics whose head and shaft members are each centrally recessed, without the recesses in any way communicating with each other.
Patent DE-2414132-A1 (DE)
Title: Bar stock feed for lathes - damps bar vibrations in guide tube by air or oil filled rubber hoses
Inventor: SCHELER HOLGER ING GRAD
IPC: B23B13/08
Filed: 1974-03-23
Abstract: The bar stock loaded into a lathe travels through a round guide tube. The four corners between this tube and an outer square guide tube ar filled up by elastic damping hoses which can be inflated by air or by oil of high viscosity. The pressure inside the hoses can be varied as required to remove the round guide tube. This system is free from any acoustic bridges between the inner and outer guide tube so that vibrations caused by the bar stock revolving inside cannot be propagated. The degree of damping can be easily adapted to the sound frequency and the inner guide tube can be exchanged easily. A control valve permits the filling pressure to be varied and the medium to be emptied.

Patent DE-2420303-A1 (DE)
Title: Stacking and packaging of large blanks - has crosswise separation of blanks, by transverse conveyor movements
Inventor: LOBENHOFFER HANS
IPC: B65H29/16
Filed: 1974-04-26
Abstract: The process uses a depositing tray, with lifting stage, and a sliding stage with a number of longitudinal conveyors. After the longitudinal separation of the blanks due to an increase in speed on the conveyor between the two stages, the blanks are separated cross wise by a pre-selected transverse movement of the longitudinal conveyors on the sliding stage. The blanks are then moved onto subsequent storage conveyors by selection of groups of longitudinal conveyors. The longitudinal conveyors are moved in such groups, that they cannot move relative to the stacks of blanks above them. A stacking unit with grab and raising tools, and alignment units is positioned behind the sliding stage. It forms a high stack, and feeds it directly into a packaging unit.
