Title: Determining the commercial quality of meat, esp. pig carcasses - using two identical probes with pneumatic cylinder to ascertain fat layer thickness
Inventor: BREITSAMETER HANS
IPC: G01B7/06
Filed: 1976-01-23
Abstract: The outline of the meat is scanned in the longitudinal direction of the carcass from end-to-end, and the greatest thickness of the ham portion in a transverse direction is measured.

Title: Electromechanical multi-channel recorder with cyclic scan - has multi-plexor which scans parameters and compares with max. and min. references
Inventor: SCHLEBAUM KAREL HENDRICK
IPC: G01R17/04
Filed: 1976-02-13
Abstract: The electromechanical multi-channel recorder is used to cyclically plot electrical parameters such as voltage or current signals with limiting values. The parameters to be measured and the individually adjusted limited values are scanned cyclically by a multiplexer and compared with minimum and maximum references. The references are produced from a comparator signal generator and are a monotone increasing or decreasing function of the series of positioning pulses. The drive of the recording medium is synchronised to the references via logic circuits. The minimum and maximum references are also recorded. They are derived from bistable multi-vibrators, with the processed pulses transmitted via the multiplexer.

Title: Plasterboard cladded solid wall sound insulation - has plaster pumped into rear spaces as backfilling using compressed air
Inventor: KREUZPOINTNER RUDOLF
IPC: E04B1/82
Filed: 1976-04-07
Abstract: The process is for restoration of sound insulation in solid masonry or concrete walls with a punctiform-cemented cladding of rigid plasterboard panels which normally causes loss of the insulation.

Title: Solid state commutating circuit for brushless DC motor - uses stator current control overriding commutation pulsing circuit
Inventor: LISKA MANFRED DR ING
IPC: H02P6/24
Filed: 1976-07-07
Abstract: The motor stator windings (1-4) are star-connected through current measuring resistors to one DC pole, and through commutating transistors to the other pole. Freewheel diodes round each winding are connected to the first DC pole through a voltage regulating circuit. The current measuring resistors are connected, via. decoupling diodes to one input of an operational amplifier, the same input also being connected to a controllable voltage to form the summing junction. The amplifier output drives a blocking transistor. The transistor triggering circuit is controlled by a rotor position signal. When one path turns on, the winding current flows. If the set maximum is reached, the operational amplifier output changes sign and the blocking transistor is energised. This causes the commutating transistor to turn off and interrupt the winding current.

Title: Filtering solid-liq. dispersions, esp. photographic dyes - using a porous tubular filter and maintaining dispersion at a specified flux rate
Inventor: DYER GERALD THOMPSON
IPC: B01D46/24
Filed: 1977-11-11
Abstract: Solid/liq. dispersions in which the solids have a particle size distribution of 0.1-50 mu are filtered by circulating the dispersion through a filter comprising tube (s) having rigid porous wall in which the pores have a micron rating of 0.5-5 mu. The dispersion is maintained at a flux rate sufficient to prevent particles of a size less than the micron rating from passing through the pores. Liq. is removed through the pores and the solids concn. of the dispersion increases. Used for washing and concn. of aqs. dispersions of photographic dyes. Dispersions having particles of a dia. about 20 times less than that of the pore rating of the tubes can be filtered using low pressures, e.g. less than 50 psi. The process is esp. effective for filtering dispersions having a solids content 20% wt. and a viscosity of 20-850 cps at 30 degrees C, which is the pref. operating temp.
