Title: Magnetic tape transport speed checking control for minimum delay - is provided by logic circuit coupled to monostable multivibrator to provide shaped gating signal
Inventor: KLUMPP MARLIN K
IPC: G11B15/093
Filed: 1975-02-07
Abstract: A fast response circuit allows the transport of magnetic tape in a cassette recorder to be changed from one speed to another in a minimum time period. The transport speed of the tape is controlled by a motor drive circuit (40) coupled to the motor winding (29) and drive shaft (25). A tachometer (32) generates a square wave output (34) that may be modified in frequency and/or mark/space ratio to provide speed variation. When checking of tape speed is called for, the transport control circuit (35), output goes low (42) the three NAND gates (52, 54, 60) combine to generate a short negative pulse (69).

Title: Braking distance indicator for motor vehicles - combined with speed indicator gives driver warning of safe stopping distance
Inventor: SCHWOTZER MANFRED
IPC: G01P1/08
Filed: 1975-03-04
Abstract: The braking distance indicator can be combined with another instrument such as a tachometer, speedometer on the dashboard of a motor vehicle or in the instrument cluster of a motor vehicle. The scale may be circular and form the inner part of the speed or revolution indicator or be of the linear moving strip type. The stopping distance scale in combustion with the speedometer has the advantage of giving the vehicle driver an immediate indication of the required braking distance related to his speed at the time so that he may maintain a safe distance between his own and a vehicle ahead in anticipation of an emergency stop.

Title: Car safety belt winding lock - has metal ball to hold safety belt lock in free position
Inventor: UBUKATA SUSUMU
IPC: B60R22/40
Filed: 1975-04-07
Abstract: The mechanism consists of a housing (1, 2, 3, 4) where a safety belt (5) is fixed to a roller (6) which rotates on its central shaft connected to a spiral spring by an anchor pin which holds the belt wound up.

Patent DE-2539390-A1 (DE)
Title: Stereo sound image improvement - injects compensation signals at source to enhance spatial impression
IPC: H04S1/00
Filed: 1975-09-02
Abstract: The method for improving the spatial definition of stereo-phonic signals is based on the provision of compensation signals which are used to separately excite the listener's ears, thereby giving the impression of a wide audio image. The compensation signals are impressed onto an audio carrier and are either separately, or mixed with the original signals, during recording of the stereophonic input, fed to the ulti-channel system. The compensation signals are produced at the input stage. This means that no additional equipment is required at the reception or playback stage. The reproduction of the improved sound image can be achieved using normal stereophonic equipment. The method could be used to relay quadraphonic audio signals for reception by a normal two-loudspeaker stereo equipment.

Title: Tank discharge and filler valve with spring loaded piston - has internal seal flange for piston location
Inventor: MEGES HELMUT
IPC: F16K27/07
Filed: 1975-09-17
Abstract: A filler and discharge valve for a liquid tank has a spring loaded valve piston (4). The tubular valve body (1) which is screwed into the tank wall, has an internal flange (11). The flange houses a seal ring (12) and it also locates the hollow valve piston (4). A compression spring (5) holds the valve piston in a position which closes the outlet flow.

Title: High frequency division by any ratio - uses one adjustable counter with delay circuit taking over during counter resetting
Inventor: PAPHITIS ALEXANDER DIPL PHYS
IPC: H03K23/66
Filed: 1975-10-01
Abstract: The counter is preset so that it reaches its end state after a number of input pulses smaller by a specific number than the required division ratio. When the counter end state is reached, it delivers a signal to a clock pulse controlled delay circuit, whose delay is equal to the difference between the division ratio and the counter end state. Pulses applied to the counter until its end state is reached are then applied as clock pulses to the delay circuit which delivers an output signal after the specified number of pulses. The counter is reset to its preset state during the period when the delay circuit is operated by clock pulses.

Patent DE-2605505-A1 (DE)
Title: Gritting attachment for vehicle wheels - has gravity fed hoppers and air blown spreader operated by electromagnetic valves
Inventor: HOCH AUGUST
IPC: B60B39/10
Filed: 1976-02-12
Abstract: The gravity fed grip hoppers are mounted under the bonnet and above each rear wheel. The front, single hopper, feeds spreader jets in front of each front wheel, with the grip spread into a wide track to accommodate steering movements of the wheels. The rear jets provide a thin track for improved grip. The grit is blown out of the hoppers and spreaders by compressed air from a main supply, backed by a reservoir, and operated by electro magnetic valves. The line between the hopper and release valves and the jets is curved to retain grit when the air pressure is off. This provides a constant supply of grit at the jets for immediate application when the valves are operated. The flow rate is adjusted by simple throttle valves.

Title: Take off guidance for selfpropelled missiles - uses guides inclined to each other to provide compensating angular velocity at lift off point
Inventor: SOMMER HEINRICH DIPL ING
IPC: F41F3/04
Filed: 1976-02-27
Abstract: Guidance blocks used during the take off of self propelled missiles are located on guideways inclined to each other to provide an angular velocity to compensate for the effect of gravity. Guidance blocks (1, 2) move with the missile during the initial phase of take off. The centre of gravity (S) is located within the distance spanned by the blocks.
