Patent DE-2654425-A1 (DE)
Title: Swinging axle for excavator - has pneumatically operated slide valve to change from working to travelling positions
Inventor: PILOT HARRY
IPC: B60G17/005
Filed: 1976-12-01
Abstract: The axle (3) pivots in relation to the chassis on a central bearing point (2). Hydraulic cylinders (4) fixed to the chassis are connected to a hydraulic circuit containing a regulator slide (11) which controls the movement of plunger bearing on the swinging axle to move the chassis from a working position to a driving position. The regulator slide contains a piston which is subjected to compressed air pressure via a switch over valve (7) to change from one working condition to a second. The fluid volume differences from the levelling cylinders (4) is accommodated by a pressure chamber and returned to the hydraulic system.

Title: Batch type powder conveyor - with inlet seal device and means of weighing batches despatched
Inventor: OTTERBACH JOACHIM ING GRAD
IPC: B65G53/66
Filed: 1977-01-29
Abstract: Continuous pneumatic conveying of mobile material esp. coal dust in accurately metered amts., is extracted in an appts. wtih seal device for discontinuous acceptance of the material at atmospheric pressure followed by discontinuous discharge at the conveying pressure. A conveying vessel is joined directly to the seal with >=1 jets directed into conveying pipes together with other conveying devices. The seal device and the conveying vessel are rigidly joined together and coupled externally by flexible piping, the whole being mounted on a weighing system. This generates an actual weight for the weighing operations. A set point generator is used to feed a set point into the controller. A balancer compares the two signals, and several actuator motors are provided to set the conveying system, these being motivated by the signals sent to them. Used for providing batches of coal dust to coal gasification operations. The use of pneumatic conveying provides rapid feedng of batches with good distribution in the reactor. The system gives accurate metering.
Patent DE-2704716-A1 (DE)
Inventor: STROBL JOERG DIPL ING
IPC: H03M1/00
Filed: 1977-02-04
Abstract: Analog/digital converters only have the accuracy needed for the set task within a certain range. However, the range of the analog signal is frequently greater so that this is not always converted accurately. The device can be used for increasing the accuracy over the entire range in that the analog/digital converter (7) is supplied with two analog signals, both of which are functions of the same physical quantity (10) to be measured but differ from one another at a ratio of 1:16. The ratio is given by the resistors (2, 3) and selected in such a manner that, within a certain range of the physical quantity to be detected, one signal occurs at a level which can be processed with high accuracy by the analog/digital converter whilst the other signal has this level in another range of the physical quantity to be detected. The analog/digital converter (7) converts all these signals into digital expressions which are applied in parallel or serially to digital inputs of the computer (9). <IMAGE>

IPC: A47B95/00
Filed: 1977-04-19
Abstract: Housing (16) is attached to the cupboard (12) at least partially behind its rear wall (31) so that a holder (17) supported against the wall (13) and which interacts with an infinitely adjustable positioning element (19, 20) can be moved relative to the housing in order to adjust the height of the cupboard. This adjustable positioning member (19, 20) is accessible from the inside cupboard (12) through at least one opening (66) provided in the rear wall (31). The depth of the housing (16) pref. corresponds to the amount of the side wall part of the cupboard (12) which protrudes backwards beyond the rear wall (31). Since the bracket is mounted outside of the interior of the cupboard the useful space of the latter is not impaired by the bracket. The openings (66) which provide access to the positioning member can be closed after use by a stopper so that the rear wall of the cupboard retains an unbroken surface.

Title: Illustration formation system with scanner - uses slight spot source detected to generate video signal and produce image on screen
Inventor: CASEY SUSAN D
IPC: G06T17/00
Filed: 1977-06-10
Abstract: The system forms an illustration, using a light spot source which is detected to generate a video signal. A number of signals are generated to represent screen signal parameters, and from these a screen signal is formed. From the latter and the video signal a modified video signal is generated and represented as an illustration in a complete individual picture. The illustration is then recorded. The light source can be monochrome, or can determine two or more grey tone levels. It can be divided by contrasting lines into two or more sections.

Title: Antitheft grid for self-service sales stand - is designed like blind movable in lateral guide rails for easy closing when not supervised
Inventor: HAGEN HEINRICH-W
IPC: A47F1/04
Filed: 1977-07-30
Abstract: The self-service cigarette rack or similar sales stand has an anti-theft device in the form of a protective grid which is designed like a blind and moves in a guide so that in one position it releases the access opening and in the closed position it can be locked to prevent theft. The blind-like grid can be displaced very easily between these two positions directly in the plane of the access opening without any extra space in front of the machine. The protective grid can be wound up onto a roller which can be placed behind the opening surface in a reinforced attachment set above the access opening. This enables the rack to be closed when e.g. a check-out position is temporarily vacated.

Title: Visiting or greeting card made of metal - is gold or silver plated with engraved words to enhance value
IPC: B42D25/00
Filed: 1977-08-18
Abstract: Visiting or greeting cards rarely have any intrinsic value and are usually thrown away by the recipient. In order to encourage their retention it is proposed to make the cards of metal which is plated with gold, silver or platinum. The thickness of the precious metal plating is between 0.1 and 0.5 mm. The card is inscribed with suitable greeting or information and carries the firm's trademark with a reference number. The information can be etched or photo-engraved. The card thus makes an impressive gift which is unlikely to be thrown away regardless.

Title: IC engine ignition system with several sequential sparks - has spaced electrodes on plugs around circumference and axis for complete combustion
Inventor: NISHIO KANEMITSU
IPC: F02P15/10
Filed: 1978-03-14
Abstract: An I.C. engine ignition system produces several sequential spark discharges between adjacent electrode surfaces in various positions. The ignition system is intended to reduce environmental pollution caused by the exhaust gases. The engine cylinders are fitted with sparking plugs with spaced electrodes. There is a circuit with the output connected to the electrode which produces several high voltage pulse sequences at intervals of 50-500 microseconds during each ignition cycle of the I.C. engine. This will produce an equal number of sequential spark discharges at various points between the surfaces of the electrodes. Each sparking plug has a central electrode and two radially displaced circumferential electrodes. The spark discharges form a radial pattern.

Title: High output dental inspection lamp - uses molecular radiation discharge lamp with daylight characteristics as light source without filter
IPC: F21S8/00
Filed: 1978-09-14
Abstract: The dental inspection lamp fitted with a reflector, uses a molecular radiation discharge lamp with daylight characteristics instead of a previous type using a halogen lamp.
