Title: Material transport equipment for grillers - has eccentric bars rotating in recesses in treatment surface
Inventor: BIRKE GERHARD ING GRAD
IPC: A47J37/04
Filed: 1975-07-18
Abstract: The equipment is for the transport of material, particularly food for roasting, moved intermittently over a treatment surface and temporarily deposited on it. The treatment surface (8) has a series of recesses (7) one alongside the other. In these recesses eccentric transporter bars (3) rotate, their upper edges protruding above the level of the surface in the highest position. The bars can be mounted in a common frame carried in eccentric bearings, and the eccentric movement of bars or frame can take place steplessly, or in stages by altering the speed.

Title: Stable electrostatic developer based on nonaq. dispersion - of graft copolymer and polyethylene (wax) and or paraffin wax
Inventor: TSUBUKO KAZUO
IPC: G03G9/13
Filed: 1975-07-18
Abstract: The developer consist of pigment or dye dispersed in a non-aq. dispersion of a graft copolymer (I) and polyethylene (IIa), polyethylene wax (IIb) and/or paraffin was (IIc) with a softening point of 60-130 degrees C in a liq. vehicle comprising an aliphatic (halo)hydrocarbon (III) with a high resistance and low dielectric constant, this dispersion being prepd. in 3 stages at elevated temp. In stage (a), a monomer (IV) of the formula CH2:CAR (in which R is H or Me. A is -OCnH2n+1 or -COOCnH2n+1; n = 6-20) is copolymerised with (meth)acrylic, fumaric, crotonic, itaconic and/or maleic acid (V) and/or glycidyl (meth)acrylate (VI). Then (b) the resultant copolymer is esterified with the other of the components (V) and (VI) and finally (c) grafted with a vinyl monomer (VII), i.e. (meth)acrylic acid, lower (1-4C) alkyl (meth)acrylate, (methyl)styrene and/or vinyl acetate. (II) is added in one of of these 3 stages and the prod. is cooled with rapid stirring. The dispersion has high dispersing power for pigment or dye and is stable for long periods, e.g. 8 months. It can give a bright, dense copy, suitable for use as original for offset printing, which can be transferred easily to a substrate, e.g. paper.

Title: Electric machine brush holder with roll tape springs - has contact surface of roll spring set obliquely to pressure piece to restrict latter's radial movement
Inventor: SCKERL WALTER
IPC: H01R39/38
Filed: 1976-02-20
Abstract: Electric machine brush-holder has one or several direct action roll tape springs and a slide-shaped pressure-piece arranged centrally over the brush(es) and coaxially to the brush(es) axis to force the brush(es) against the commutator or slip-ring(s). To provide play-free guidance for the pressure-piece and at the same time to restrict the radial movement of the pressure-piece in the face of small radial amplitudinal movements of the carbon brushes, the bearing or contact surface of the roll-spring is set obliquely to the pressure-piece in such a way that a component of the spring force is set up to run transversely to the direction of movement of the pressure-piece. More specif. the transverse component of the spring force travels via the sliding surface of the pressure piece to the brush(es) holder body.

Title: Bulk material weighing system - is used on belt weighing machines and uses weighbridge, pulse generator, multiplier and force measuring cell
Inventor: MIROW HANS DIPL ING
IPC: G01G11/18
Filed: 1976-03-18
Abstract: The appts. weighs portions of the bulk material on a conveyor belt. It uses a weighbridge, pulse generator, multiplier and force measuring cell. A first signal is multiplied by a second signal which is proportional to the belt speed. The second signal is a pulse train the pulses of which select single values from the time continuum of a signal proportional to the momentary weight of the weighbridge. The last single values are added to a predetermined maximum number of quantities to be summed. The sum divided by the number of quantities results in the first signal. The signal from the force measuring cell (3) passes to the input of an analogue-to-digital converter (0).

Title: Infra:red baking esp. of spiced cake with temperature control - using cooling air stream to prevent premature rising
Inventor: RINDERLE KARL
IPC: A21D6/00
Filed: 1976-04-03
Abstract: Method includes the conveying of the products past infrared radiant heaters. Simultaneously with the radiant action of the heaters, the prod. is subjected to a stream of cooled air, pref. largely humidified before it reaches the prods. Pref. the flow rate and/or humidity content of the air is kept constant, while the temp. and/or humidity content is regulated by mixing previously dried fresh air with the cooling air. The duct through which the cooling air flows over the products is pref. shielded from direct action of the heaters. The rapid heating up obtainable with infra-red heaters is achieved without risk of the prod. being burnt, esp. at the surface, or of the expanding agent in the prod. becoming prematurely activated.

Title: Depth digital balancing during ultrasonic testing - using ultrasonic head signals which are measured, corrected and converted into logarithmic binary amplitude values
Inventor: FOERSTERMANN ULRICH ING GRAD
IPC: G01N29/40
Filed: 1976-05-28
Abstract: The depth digital balancing occurs during ultrasonic testing. Amplitude correction values corresponding to one or several attenuation characteristics are read out by a propagation time address from a table store, in which they are stored in steps of e.g. 133 nsec. Ultrasonic signals received by ultrasonic heads are measured and converted without pre-compression into logarithmic binary amplitude values with allocated binary propagation time values and cycle diaphragm addresses. These binary amplitude values are added by a high speed adder to the read out from the table store correction values. They are then further processed into corrected binary amplitude values available for further processing or evaluation.

Title: Valve shaft and cover with bellows seal - is produced by using heat conductive clips in assembly prior to welding
Inventor: HOLLOWAY LEONARD ROBERT
IPC: B23P15/00
Filed: 1976-07-23
Abstract: The production of the valve system is carried out in the following stage: First the bellows contact surface is formed on the shaft and cover (10). Then the sealing bellows (11) is mounted in relation to pulse surfaces. A multiple clip (20) of metal with good heat conductivity secures the bellows round the shaft contact surface near the line of welding. Pulsed welding is then used for final connecting of the bellows to the shaft, with low heat supply during this operational step. Then the cover is mounted on the shaft and connected to the other end of the bellows, and clamped in position near the line of welding. After final welding the clips are removed.

Title: Multi system circular knitter - has control for needle groups to work in a reinforcing stretch yarn before it is cut (CS291176)
Inventor: KEJNOVSKY BOHUMIL DIPL ING
IPC: D04B9/18
Filed: 1976-09-23
Abstract: The appts. is for the insertion and working of a reinforcing stretch yarn in a multi-system circular knitter, partic. for the mfr. of stockings, where the stretch yarn is laid in >=2 knitting systems and cut. A reinforcing yarn is knitted in by one group of needles and, after knitting, the reinforcing yarn is again knitted round most of the fabric for the ends of the yarn to be cut after the last needle of the group. The system ensures that the reinforcing stretch yar is fully secured before the end is cut so that, on reasserting itself, it does not retreat back into the knitted fabric and lead to a fault.
