Patent DE-2344540-A1 (DE)
Title: Rotary step switch has bayonet-type locking ring - below stationary contact board with sprung rotor pushing board onto ring
Inventor: VEIZ KURT
IPC: H01H19/58
Filed: 1973-09-04
Abstract: The rotary step switch has a rotor whose spring-loaded contacts press down onto contacts on a stationary circuit board. The shaft passes coaxially through the rotor and board and ends just below the board. A bayonet-type locking ring engages with the shaft end. The circuit board is pressed against the ring and the ring is held in place by the spring spring-action of the rotor contacts. The shaft end has inverted U-shaped slots into which inward-pointing radial projections on the ring engage.
Patent DE-2359123-A1 (DE)
Title: Ferrite antenna tuning system - has two short-circuiting rings around ferrite rod ends to alter coupling to coil
Inventor: ROESKE WOLFGANG DIPL ING
IPC: H01Q7/08
Filed: 1973-11-24
Abstract: The tuning system, for a ferrite antenna, has the coil in the antenna resonant circuit wound around the ferrite rod. Two short-circuiting rings are located around the ends of the ferrite rod and can move axially along it. The resonant circuit is tuned in frequency and bandwidth by altering the coil damping. This is achieved first by altering the coil coupling by sliding the first shorting ring: this sets the bandwidth. The ring sets up back magnetic fields through the coil. The second ring is then moved along to set the resonant frequency. The second ring can be made of silver plated copper, and the first of shorted windings.
Patent DE-2361560-A1 (DE)
Title: Stabilised floating working platform - with triple buoyancy tanks linked to platform by movable struts on each platform corner
IPC: B63B35/44
Filed: 1973-12-11
Abstract: The triangular working platform has vertical support pillars at each corner with the bottom of the support pillars fitted with triple, horizontal struts. The end of each strut is hinged at the top of a cylindrical buoyancy tank with the tank pivoting in one plane with a limited displacement. The system enables the buoyancy tanks to swing with the sea while ensuring a stable working platform, even in storms. The height of the platform above the meeting point of the struts is made adjustable.
Patent DE-2365514-A1 (DE)
Title: Window ccleaning device for household use - has steel wool corner inserts and diagonal handle across top
IPC: A47L1/05
Filed: 1973-02-12
Abstract: The window cleaning device which can be used safely by housewives comprises a rectangular housing with steel wool inserts at the corners which is particularly suitable for cleaning in the corners of the windows. The window cleaning apparatus can be provided with a central cleaning disc which is driven by an electric motor. The top of the housing is preferably provided with a handle extending diagonally across.
Patent DE-2412590-A1 (DE)
Title: Adjustable cam for actuating electric switch - is provided with both coarse and fine adjustment of angular setting
Inventor: SCHWOERER HERMANN
IPC: F16H53/04
Filed: 1974-03-15
Abstract: The cam and clamp are mounted on the central portion of the shaft and retained by the circlips fitting in the grooves. The clamp is fixed to the shaft by means of the bolt and nut. The pin fits in the hole with the projection entered through the slot and the pin is then rotated through 180 deg. so that projection is retained in one of the radial serrations and is normally held in the position by the spring. The eccentric extension fits in the slot in the camplate. Coarse adjustment is provided by the clamp, fine adjustment by rotating the pin using the screw driver slot.
Patent DE-2414461-A1 (DE)
Title: Combine harvester cutter blades - are automatically spaced from ground via electrical switches
Inventor: SCHUMACHER II GUSTAV
IPC: A01D41/14
Filed: 1974-03-26
Abstract: The grain lifter is fixed with its support arm to the cutter bar fixture-screw and to the cutter-bar, and has a sliding bar joined to the support-arm. The sliding-bar is bent upwards at the back. Two parallel contact-bars, isolated from the cutter-trough, are positioned on its front edge. The back end of the sliding-bar rests on the two contact-bars, depending on the stroke of the grain-lifter, and, depending on the load exerted, closes either with contact one contact-bar or the contact with the other contact bar. The switch contacts released by the grain-lifter, close circuits which in turn act upon the hydraulic control and affect the control of the lifting cylinder according to the lay-out of the ground.
Patent DE-2414934-A1 (DE)
Title: Circular knitter electro-magnetic patterning - has a permanent magnet to hold sinkers in pattern cylinder until selected
Inventor: MUELLER GERHARD
IPC: D04B15/78
Filed: 1974-03-28
Abstract: An apparatus is claimed for electro-magnetic pattern execution in a circular knitter, where there are two magnets for the positioning of the selectors in the knitting systems, with the second magnet in the form of a permanent magnet mounted to the cylinder supporting the selectors. The system allows a weaker magnetic force to be used to hold the selectors, until the selecting magnet is energised, which reduces the size of magnet needed without allowing damage to the selectors through relative movement in operation.
Patent DE-2420686-A1 (DE)
Title: Glass fibre reinforced thermoplastics prodn. - fibres being injected into only the homogenisation zone of barrel
Inventor: HENIS DOV B DR
IPC: B29C45/00
Filed: 1974-04-29
Abstract: A method of injection moulding thermoplastics material reinforced with glass fibres is as follows: particles of thermoplastics are introduced into a barrel housing an advancing and withdrawing screw and, separately from these, short lengths of glass fibre are introduced into the barrel in a region terminated by the nozzle end and comprising the homogenising or metering zone, these glass fibres are introduced while the screw is in the withdrawn position. Pref. the glass fibres are introduced in a zone where plasticising of the resin has already been completed.
Patent DE-2427405-A1 (DE)
Title: Calculating view finder with spirals as determining factor sources - has twin glass spirally engraved discs synchronously rotated
Inventor: DEUERLEIN ERNST
IPC: F41G3/06
Filed: 1974-06-06
Abstract: A calculating view finder with spirals as sources of aiming-off determining factors has a pair of similar glass discs in a mirror picture layout one above the other with the spiral details engraved thereupon and a convex lens lying between the discs. Synchronous rotation of the glass discs and radial and tangential movement of their centres of rotation in the image plane permits allowances to be made for accurate aiming on a moving target. By applying a mask with a slit corresponding to an arc an artificial lighting arrangement may be used. The lens cross-section only can be made visible by darkening the glass discs from the edge to the outsides of the spirals.
