Patent DE-2340054-A1 (DE)
Title: Light-weight weather-resistant table-tennis table - comprises aluminium top and bottom with sound-absorbing lining
Inventor: KETTLER HEINZ
IPC: E04C2/34
Filed: 1973-08-08
Abstract: Between the aluminium top and bottom plates of the table tennis table top are aluminium spacer members which are firmly connected to the two plates. The distance members may form a plate the same size as the top and bottom plates and can be connected to the top plate by means of the intermediate sound-absorbing layer which may consist of metal or plastics or hard fibre plate and serves as a reinforcement or stabilising plate. The cavities between the top and bottom plates and between the spacer members are preferably filled with a foamed plastics material. All these materials are weather-resistant and unlikely to warp.

Title: Sliding hatch covers for ship - slid sideways to stack on platforms which pivot down between hatch sill and railings
Inventor: KLOESS PETER DIPL-ING
IPC: B63B19/18
Filed: 1973-08-25
Abstract: The hatch covers are arranged with the inner ones higher than the outer ones so that they are slid aside on top of the outer ones. The stack of covers is then slid further onto special platforms hinged on the sides of the hatch sills and extending over the side of the ship. The platforms are fitted with hydraulic rams so that they can be swung down into a vertical setting between the hatch sill and the side of the ship. This enables the hatch covers to be moved completely clear of the hatch in a confined space.

Patent DE-2424730-A1 (DE)
Title: Regulation of D.C. using external voltage controlled multivibrator - differencing amplifier controls multivibrator frequency with constant pulse output
Inventor: LIEBERS LUTZ
IPC: H02M3/156
Filed: 1974-05-20
Abstract: The control of a d.c. supplied to a load is based upon a variable frequency signal dependent upon comparison of output voltage with a reference. A variable frequency multivibrator (VCM) is voltage controlled by the difference signal generated by a differencing amplifier circuit (T1, T2). The multivibrator output is of a sawtooth profile that is shaped into a square wave by a digital monostable. As the difference between the reference and the output voltage increases the multivibrator frequency increased, but the monostable pulse width remains constant. The monostable output is transmitted through an LC filter circuit coupled to the load. By holding the pulse width constant over the frequency range the average output level is modified.
Patent DE-2426164-A1 (DE)
Title: Motor vehicle horn switch - has sprung contacts differentially actuated to give dual level of sound
Inventor: PRANG JOSEF
IPC: H01H41/08
Filed: 1974-05-29
Abstract: The vehicle horn contact system has a contact spring actuated by a pin. The common switch actuates a first horn in one of its positions and in another position it actuates the first and the second horn together. The actuating pin (20) has an extension (22) of smaller diameter and a compression spring (17) encloses this extension and spring ends rest against the pin shoulder and contact arm. On actuation the pin pushes the contact arm (14) until it contacts first the contact (23) and energises the horn (H1). On further depressing the other arm of the contact spring energises also the horn (H2) on contacting contact (25). Thus the level of sound is increased as the button is pressed harder.

Title: Rake with prong support back - has back bent away from both horizontal and vertical axes
Inventor: GOEBEL FRITZ
IPC: A01D7/00
Filed: 1974-08-22
Abstract: The rake is designed so that the prong support back is bent away from both the horizontal (3) and vertical planes (5). The prong support back of the rake is bent downwards from the horizontal plane (3) and away from the vertical plane (5) in the raking direction (6). The material used for the manufacture of such a flexible rake with bent prong support back is of an elastic ductile type and may typically be a plastics material.

Title: Foam plastics ring cores moulded inside tubes - in quick closure moulds moving in mass production line
Inventor: SCHWARZENBERG HANS-JOSEF
IPC: B29C44/14
Filed: 1974-09-13

Title: Sewing machine controls - with finger bridging keys in two detachable boards for switching integrated circuits for control functions
Inventor: ENGELHARDT SIEGFRIED
IPC: H01H9/06
Filed: 1974-09-16
Abstract: An electronic control system for indl. sewing machines uses two alternative key boards which can be attached to the machine in the two most accessible positions. Each key contains two conductive strips, sepd. by a smaller air gap, which is bridged by laying a finger across the strips. This actuates integrated circuit modules and their output signals are amplified and transmitted to the functional control elements of the sewing machine. Light-emitting diodes over each key indicate the selected function. This prevents errors by a multitude of finger-, hand-, foot- and knee-operated switches. Operators can be trained more quickly in the work with a machine. The keyboards take up less space and leave one hand and four fingers of the other hand free.

The device pref. incorporates a template table for guiding the welding gun across the metal sheet. Rapid, accurate location of bolts, studs, bushes etc. is obtained and the sheet is clamped on one fixed table.
Patent DE-2452001-A1 (DE)
Title: Target plate with electric hit indication - has conducting wire grid layers insulated from each other
Inventor: SCHULZ HEINRICH
IPC: F41J5/048
Filed: 1974-11-02
Abstract: The target is provided with electric means for indicating a hit. For this purpose two electrically conducting layers are incorporated, which are insulated from each other and which cover the whole target area. These layers (4, 5) are connected to a system for indicating short circuiting. These layers are made of wire grids which are in turn subdivided into a number of sections within the same layer, which are separated from each other. These sections can be circular or arranged into squares. The use of wire grids simplifies the production of this target, and the wire grid electric characteristics can be modified more easily than, for example, those of metal foils or metal covered plastics films.

Title: Silage-storage unit for grain - incorporates loading and unloading equipment and is impermeable to gases and liquids in surroundings
Inventor: MIKECZ ISTVAN PROF DR
IPC: A01F25/16
Filed: 1974-11-20
Abstract: The housing is mounted on wheels, and has a guide-plate from which are suspended the ends of two parallel screws. The two other underneath ends of the screws are supported by a hinge. In the top of the housing is mounted a drum from which sheeting is unwound to give the heap of silage or grain being formed a cross-sectional shape of a semi-circle. On the silo sides of the housing are brackets on each of which are pivot-mounted a tubular drum and a first locking wheel. By means of an elastic, preferably rubber locking wheel drawn round the tubular drum and underneath the first locking wheel, the sheeting is fixed to a concrete base plate, thereby insulating the heap of silage or grain from the atmosphere. An intake screw with hopper operates the heaping-screw. An inflow unit with sloping scraper surface is mounted on the housing frame, and consists of a reel, and filler-hopper. The inflow unit is fed by a trailer with conveyor belt floor.
