Title: Admixing bakery dough with germinated cereal flour - to increase aroma formation starch saccharification and leavening
Inventor: LAMMERS ALBERT
IPC: A21D2/38
Filed: 1975-09-10
Abstract: Aroma formation in bakers' wares is accelerated by admixing the dough with very finely ground germinated cereal subjected to strong germination, to achieve plumule height 5-10 mm, before addn. to dough. Roots may be 20 mm long. Bread and pastry having cake-like tast e can be prepd. from cereal and water. Germinated cereal addn. strengthens aroma and shortens baking time. Saccharification of starch is increased, to an extent such that sugar or sweetener addn. is unnecessary. Leavening is intensified.

Title: Resistance butt welding machine - for welding chain links without risk of damaging the electrodes
Inventor: LANGE GERHARD
IPC: B21L3/02
Filed: 1975-09-30
Abstract: A resistance butt welding machine for welding C-shaped chain links is described. Two pairs of electrodes are placed symmetrically w.r.t. a median plane and grip each of the ends of the link. Two levers with two arms manipulate each pair of electrodes, the levers being articulated in synchronisation in the reverse direction about horizontal and parallel axes and, being able to move in a limited fashion parallel to and perpendicular to these azes. The two levers corresponding to the same pair of electrodes can pivot about a common swivel pin. Each swivel pin to absorb a radial and/or axial charge is elastically mounted in a bushing fixed to the supporting frame. The electrodes are protected from being damaged when the ends of the link are displaced sideways without any reduction in the working life of the other parts of the welding machine. Each pair of electrodes can move in a circular manner during complete closure of the link and can adapt to sideways movement of the ends of the link. The machine is less complicated than other machines attempting to prevent damage to the electrodes and therefore less likely to break down.

Title: Toe grip for ski safety harness - has toe grip arms on lateral moving slides held by spring loaded piston
Inventor: BIERMANN PETER DR ING
IPC: A63C9/085
Filed: 1976-01-27
Abstract: Ski safety harness has a toe holder (34) mounted on the ski (12) which has two lateral moving slides (13) fitted. On the outer ends of each slide (13) is a sole holder arm (16). The sole holders (16) can be either fixed sloping arms which grip the shoe sole, or an angled arm fitted on a vertical pivot (15). On the inner end of each slide (13) is a catch cam (1a). These cams fit into a catch depression in a spring loaded piston (18). This enables the sole holder arms, in the event of a frontal collision, the sole holder and slide (13) is forced outwards against the force of the spring loaded piston (18) sufficiently to allow the shoe to slide forward until it is released. This lessens the danger of the skier tumbling forwards through being held back by the toe grip after release of the heel grip.

Title: Screwless terminal for electrical installations - has clamping leaf spring with bent clamping-portions and additional central corrugated spring
Inventor: KLINKE ERNST-JOERG
IPC: H01R4/48
Filed: 1976-02-12
Abstract: The device has a fixed contact in an insulating case for clamping two wires in two channels by a clamping spring, whose bent ends clamp and lock the wire, and can be released by pressure on an insulating element. Clamping spring (2) made of a strip has its end bent at an abtuse angle (2b,2c) and an additional wavy spring is attached to its middle part (2a). Its force is directed at a right angle to those parts which hold the clamping spring (2) in its clamping position. Pressure applied to the insulating elements (3,3') is transmitted to the additional spring (2d) and moves the spring (2) from the fixed contact (1). Additional spring (2d) force is independent from the force of clamping ends.

Title: Contacting semiconductor, esp. integrated circuit - using ribbon with rounded or tapered fingers and avoiding short circuiting on encapsulation
Inventor: KAPPELMEYER RUDOLF DIPL ING
IPC: H01L23/495
Filed: 1976-02-20
Abstract: Contacting of semiconductor elements, esp. integrated circuits, with an electrically conductive ribbon with fine structures of individual fingers corresp. to the number of electrical leads is carried out in such a way that short circuits are avoided. The elements are placed in the centre of the ribbon and the leads are taken from the free ends of the fingers to the contact points by thin metal wires. After contacting, the assembly is encapsulated with a drop of plastics (I) by spraying. The novelty comprises the use of ribbon in which the critical edges of the fingers tending to short circuit with the contact wires on spraying are removed, taking the wires to the contacts so that these form a slight arc in the spraying direction and spraying with (I) of low viscosity. Yield stability of electrical parameters and reliability in operation are improved. (I) esp. on epoxy resin.

Patent DE-2709079-A1 (DE)
Inventor: IMURA TERUO DIPL ING
IPC: H02M7/162
Filed: 1977-03-02
Abstract: A line-commutated converter is connected in series, on the DC side, with a converter which can be positively commutated and with a load, both converters being supplied from the same power supply. The converters are driven such that the controllable valves of the converter which can be positively commutated are triggered by approximately the same control angle (- alpha ) before the natural commutation time which is common to both converters, at which (+ alpha ) the corresponding controllable valves of the line-commutated converter are triggered after this commutation time. This is achieved by means of two sawtooth-waveform voltages (SZu, SZu) which are offset through 180 DEG  electrical and are in each case compared with an adjustable voltage (Vi-VB or -Vi-VB respectively). This approximately symmetrical triggering is effected in that the mean values of the output voltages of the two converters correspond. A superimposed control-angle regulation can be provided in order, for example, to compensate for the influence of the overlap angles caused by the commutation and to keep the mean values exactly the same. The method is suitable, in particular, in the case of a DC motor for multi-quadrant operation. <IMAGE>

Title: Lithographic duplicating machine ink supply - has disposable container with nozzle slots dispensing ink on fountain roller when exposed to atmosphere
Inventor: SCHWEITZER ROY C
IPC: B41F31/04
Filed: 1977-06-14
Abstract: The ink package comprising a disposable container is provided for supplying ink to an ink fountain of a lithographic duplicating machine. The self-contained, sealed package is provided with nozzle openings for dispensing ink from the container directly into an ink fountain. When the openings are exposed to the atmosphere the ink used in the container is designed to be within the higher ranges of flowability for lithographic ink, and hence, due to special design of the nozzle openings, is able to flow sluggishly from the container by gravity. The ink dispensed from the container forms an ink bead at the fountain roller which increases in size until it blocks exposure of the nozzle openings to the atmosphere and shuts off the flow from the nozzle openings.

Title: Servo brake overtravel locking adjustment - uses gearwheel and pawl inside ring around outer end of adjusting nut
Inventor: SCHNEIDER WILHELM ING GRAD
IPC: F16D65/56
Filed: 1977-06-15
Abstract: The adjustment and centering device on an inner caliper servo brake has an adjustment nut for each direction of over travel in which a threaded bolt engaged on the brake jaw end is screwed and which has a stop toothing effective on one side. The teeth are engaged by a pawl and when travel occurs too far in the direction of the corresponding brake jaw it stops over a tooth. The when centering of the lock takes place, the pawl engages fully in the tooth, causing the adjustment nut to turn so as to screw out the threaded bolt. An adjustment gear wheel and the pawl are inside a ring (17, 17') surrounding the outer end of the adjustment nut (5, 5') is coupled to an adjustment plate (29) so that the displacement of the lock against the plate causes a swivelling of the ring (17, 17') and a relative movement between stop teeth and pawl.
