Title: Long-lasting flavoured chewing gum prodn. - by mixing filler-coated sweetener with gum base
Inventor: MACKAY DONALD A M
IPC: A23G4/20
Filed: 1980-09-25
Abstract: Long-lasting, flavoured chewing gum is prepd. as follows: (a) a non-sugar sweetener (I) is codried or coated with an inorganic filler (II) (wt. ratio (I):(II) is 1:10-100), then the mixt. is combined with melted fum base ingredients to form a gum base; (b) the gum base (contg. the (I):(II) combination as a uniform dispersion) is then mixed with glavours, sweeteners, emulsifiers, and plasticisers to form a chewing gum. (I) is a saccharin or aspartame. (II) is CaCO3, talc, Mg, trisilicate, diatomaceous earth, Al2O3, or mixts. The gum base and filler provide a carrier for (I) which allows a controlled, prolonged release of (I) and flavour. The filler (II) remains in the gum base and is not released with (I).

Title: Hydrostatic motor with two rings of cylinders - has axial pistons and cylinders on different pitch circles
Inventor: WEGERDT FRITZ
IPC: F16H39/14
Filed: 1980-10-30
Abstract: The hydrostatic motor has two concentric rings of cylinders round the shaft and in which pistons work. Control members for each ring have pairs of edges working together for each cylinder so as to regulate the fluid inlet and outlet. By altering the phase relationship between the strokes of the pistons and members for one ring of cylinders, a variable current of oil under pressure between cylinders with pistons working in opposite directions can be short-circuited. The two rings of cylinders are differently constructed, so that independent of the phase position of the one ring a residual torque from the pistons of the other can always be transmitted to the shaft. The pistons extend in the axial direction of the motor, and the two rings (8,10) of cylinders are on pitch circles (12,13) of different diameters.
Patent DE-3045104-A1 (DE)
Title: Loud speaker enclosure, horn construction - has medium with sound velocity lower than air, used as sound transmitter
Inventor: NEHRING ALEJANDRO
IPC: H04R1/30
Filed: 1980-11-29
Abstract: Problems arise with the customary construction of loudspeakers, from the suitability of the primary sound producer, to the wave resistance of the surrounding air, where low frequencies are concerned. In order to change the dimensions of the loudspeaker box, which is built in a horn fashion, a medium with a lower sound velocity than air, is used as transmitter between the primary sound producer and the surrounding air. Stability and weight problems oppose the use of large loudspeaker membranes, as well as problems of achieving a satisfactory efficiency with such membranes. By using a different medium, the dimension can be reduced in proportion to the relationship of the sound velocities, since the wave length of the lower cut-off frequency is proportional to the sound velocity. The closure of the horn from the surrounding air is achieved by using a flexible, thin membrane with a low mass. This prevents the filling medium from escaping.

Title: Adjustable hanging fitting
Inventor: SCHMID GUENTER
IPC: A47B95/00
Filed: 1981-03-23
Abstract: A fitting for hanging an item of furniture on a wall is specified, whose fitting parts to be attached to the item of furniture and to the wall are adjustable both in the direction of height and in the direction of depth. In order to be able to carry out these two adjustment movements from inside the cabinet through an opening in the rear wall of the cabinet simply by turning a tool about an axis perpendicular to the rear wall of the cabinet, a deflection gear is provided, which converts the turning of the tool about an axis perpendicular to the rear wall of the cabinet into a relative movement between the fitting part attached to the item of furniture and the fitting part supported on the wall in the direction of height adjustment. This 90 DEG  deflection gear consists of a worm drive which operates on an adjusting spindle via which the fitting part supported on the wall is supported on the fitting part attached to the item of furniture with interposition of a holding part. This holding part is connected to the fitting part supported on the wall via a swivel joint with a horizontal swivel axis, and the depth-adjustment movement is provided by a second adjusting spindle which engages, on the one hand, on the fitting part attached to the item of furniture and, on the other hand, on the abovementioned holding part.

Title: Device for matching the speed of rotation of the driven wheels of a motor vehicle
Inventor: BRASCHEL VOLKER ING GRAD
IPC: F16H48/20
Filed: 1981-04-30
Abstract: A device is proposed for matching the speeds of rotation of the driven wheels of a motor vehicle which has a so-called differential gear. The difference in the speeds of rotation of the driven wheels is sensed and if a predetermined differential limit is exceeded the brake (24a, 24b) of the more rapidly rotating driven wheel is applied. In this way a differential lock can be achieved by electronic means. The speed differential is measured either by way of speed sensors (10, 11) arranged on the wheels or via a sensor actively connected to the differential wheel of the differential gear. <IMAGE>

Title: Slide fastener for parts of little flexibility
Inventor: RUSCHHAUPT WILHELM DIPL ING
IPC: A44B19/02
Filed: 1981-05-14
Abstract: To connect sheets (of metal or plastic or the like) of little flexibility, a slide fastener is proposed which differs from conventional (textile) slide fasteners due to the fact that its plane of separation is disposed perpendicular to that of the sheets so that the latter only need to be bent but not compressed. Possible applications are, for example, building and apparatus claddings, collapsible containers, and also electrical cable connectors having any number of poles with a small retraction force, for example for standardised equipment and cabinet wirings and flat cables. <IMAGE>
Patent DE-3120470-A1 (DE)
Title: Metering and spray device attached to a vehicle
Inventor: SCHMIDT MANFRED DIPL ING
IPC: A01M7/00
Filed: 1981-05-20
Abstract: In order to reduce the problems occurring in particular when dispensing plant-treatment agents, a device with two containers for separately transporting and dispensing together, in particular, liquid plant-treatment agents and water is attached to a vehicle. With the aid of compressed air, the plant-treatment agent is fed into the stream of water, the amount of the metering stream being capable of being kept constant by means of the differential pressure between water and compressed air by means of a differential pressure controller or being capable of being varied in proportion to the travelling speed. Instead of by means of the change in the differential pressure, the metering flow can also be varied by means of a control valve in the metering line. A flow rate meter permits the system to be extended to form a metering flow control circuit. The output of water can be kept constant with the aid of a pressure control circuit or followed-up in proportion to the travelling speed. The return lines of the sub-widths of the spraying frame are thus completely dispensed with. Sub-width circuits without plant-treatment agent being returned to the water tank at a constant pressure are thus possible. The device permits operation both with constant water pressure and with constant water output volume and both with a constant flow of plant-treatment agent as well as with a constant output volume of the plant-treatment agent in any desired combination without mutual influences occurring.

Title: Method for producing a curved field coil
Inventor: FUJIOKA TETSUO
IPC: H02K15/04
Filed: 1981-06-19
Abstract: A method for producing a curved field coil (20B), which is used for the motor, comprises the step of pressing the coil unit (20B) into a curved shape. One side of the coil unit (20B) is broadened in a convex manner on the sides along a periphery outwards from the central intermediate space such that the coil unit (20B) is subjected to plastic deformation until it is in a position where the radially extending part of the rectangular conductor (11) is essentially at right angles to the curved surface of the coil unit (20B) in a sectional view along the shorter axis bisecting the coil unit (20B), as a result of which the coil unit (20B) is prevented from springing back. Furthermore, a light-sensitive artificial resin is used for insulation, as a result of which the step of heating the coil unit (20B) to high temperature after curving is avoided, so that the tendency to spring back, which would otherwise be caused by heating, is greatly limited. <IMAGE>
