Title: Process and machinery for slitting strip metal - has one edge profiled direct from wider strip
Inventor: AUSENDA GIANNI
IPC: B23D35/00
Filed: 1973-11-05
Abstract: The process relates to the manufacture of strip with a profiled edge for use in forming floor grills. Wide strip material is uncoiled from a stock roll in the direction of the arrow to pass in a horizontal plane between slitting discs. The slitting discs on the shaft are below the strip. The slitting discs on the shaft are above it. Grooves are cut in the face of the discs and the top of the circumference of a disc just intermeshes with the bottom of the circumference of a disc. Thus as the strip material passes between the opposing pairs of discs the edge is sheared to shape. Plain edged discs may be used in addition to make the cuts so providing several strands of strip plain on one edge and profiled on the other, at the same time.

Abstract: An electrophoresis appts. for carrying out gel or sheet electrophoresis comprises a vessel contg. buffer soln. and subdivided by a transverse, vertical partition into two chambers, each contg. an electrode running along the vessel floor and parallel to the partition; each compartment contains a sponge, higher than the partition and serving for supporting the object support plate, which bridges across above the partition; the vessel has internal contacts, and is designed for resting upon a bed plate having external contacts; a lid fits over and all round the vessel. Pref, each compartment on either side of the partition contains a lower, secondary partition, the sponges being incorporated in the sub-compartments on the outer side of these secondary partitions. This sub-compartment on each side may also contain third partitions running in vertical guides in the vessel walls. For gel or sheet electrophoresis, where the substances to be separated are placed on a sheet or a plate coated with gel. The apparatus is considerably simpler than previous devices and suitable for many repeated experiments.

Title: Heat sterilising foodstuffs in sealed containers - using satd. steam, and non-condensible gases as pressure compensators
Inventor: NEISS OSKAR
IPC: A23L3/10
Filed: 1973-12-20
Abstract: An installation for the heat sterilisation of fluids or solid matter such as infusion solns., or foodstuffs for preserving, in fully sealed containers, by means of saturated steam, uses non-condensible gass having a specific gravity different from that of the steam, for pressure compensation. The operation is effected in a pressure vessel, the pressure in which is a combination of the part pressures of the two mediums which are fed in at pressures in excess of that prevailing in the vessel; the satd. steam, fed in at a higher pressure and temp. range, being kinetically reduced to the sterilising temp. and the corresp. pressure, by a system of nozzles. These are arranged so that the resultant direction of the jets is directed at the centre point of the mass of non-condensible gas, in a space sepd. from the sterilisation zone by a partition permeable by steam. Makes it possible to use air as the pressure compensating medium without losing the full calorific value of pure condensing steam.
Patent DE-2400502-A1 (DE)
Title: Flowmeter for liquids - has a measurement piston moved to-and-fro by the measured medium
Inventor: WILDE HANS PROF DR ING
IPC: G01F3/16
Filed: 1974-01-05
Abstract: The flowmeter has a reversing element for the piston, which at its end positions is prevented from moving by a stopping device until it is quickly released for a transfer to its opposite end position. The stopping device consists of a permanent magnet and a ferromagnetic armature plate, with one of them mounted on the movable control element, and the other on the stationary housing. A device (spring, pressure store) accumulates potential energy at the end of the piston stroke, which generates at the control element held side a pressure sufficient to overcome the force of the housing device.

Title: Measurement of effective value of voltage in successive intervals - squaring integrating and extraction of square root
Inventor: OSTERMEYER MAX
IPC: G01R19/02
Filed: 1974-02-23
Abstract: An instrument, especially for the study of the starting effects in an electric locomotive, is used for continuous measurement of the effective value of a voltage in successive, interval-less integration times which can be selected to be one or more periods of one of a number of frequencies in a mixture of frequencies. The instantaneous value of an applied voltage is squared in an analogue multiplier and the squared values are fed to an integrator and reduced by the value of the previous integration time before integration over a second period. The resulting value is fed to a sample and hold unit of the integrator and in the next integration period is divided by the integration time in a divider after w hich the root is extracted in a unit so that the output signal at the output represents the effective mean voltage over the integration period.
Patent DE-2410947-A1 (DE)
Title: Interference inspection procedure - compares specimen shape with master by superposition of interference patterns
Inventor: ROTTENKOLBER HANS DR ING
IPC: G01B11/25
Filed: 1974-03-07
Abstract: The method for checking the shape of a specimen against that of a master uses optical interference effects, and produces very sharply defined interference patterns. Light from a source, preferably a divergent beam laser is spread by a lens and passed through a diffraction grating. The interference pattern falls on the specimen and generates a pattern of contour lines which is imaged by a lens on to a photographic plate or other recording device. Superimposition of the resulting image with that obtained in similar fashion from the master shows deviations in the form of Moire fringe patterns.
Patent DE-2422634-A1 (DE)
Title: Dough dividing machine charging hopper - with photocells operating shutter between extreme and intermediate opening positions
Inventor: SCHMIDT JOSEF
IPC: A21C5/00
Filed: 1974-05-10
Abstract: The charging hopper for a dough dividing machine is closed by an included shutter which is driven by a rack-and-pinion transmission from an electric motor. A cam on the rack operates a limit switch in the two extreme shutter positions so that the motor is stopped and is at the same time connected at the reverse polarity thus preparing the motor for running in the opposite direction on receipt of the next starting pulse. To set the shutter for an intermediate position, a third limit switch is mounted on a sliding rail for positional adjustment. This can be adjusted to maintain a constant dough level in the hopper, using simple means. This ensures a reliable operation of the subsequent dividing machine under all working conditions.

Title: Drive mechanism for articulated tractor - has power take off with reduction gear operating independently from vehicle drive
Inventor: BREUER FRANZ JOSEF
IPC: B60K17/22
Filed: 1974-07-12
Abstract: A vehicle front end and rear end are connected by a vertically elbowed axle. A plate clutch is used and its output drives the final drive shaft as well as a power take off (P. T. O.) operating with a speed reduction gear. The advantage claimed for the design is that the speed of the (P. T. O.) is independent of the final drive condition.

Title: Driving unit for large roller-mills - using synchronous linear motor to drive rotor fixed revolving pan
IPC: B02C15/04
Filed: 1974-11-08
Abstract: Parent patent described a drive unit for roller-mills with a vertical axis round which a horizontal pan rotates, and rolls revolve on the surface of the pan, the roll-axles being subjected to pressure; underneath the pan is an electric motor, the rotor of which is located round the periphery of the bottom of the pan, and the rotor is surrounded by a stator fixed in the mill housing. In the present invention, the novelty is that the rotor is the sec. of a synchronous linear motor and the stator is the prim., consisting of one or more inductors arranged round the sec. The main patent eliminated the need for redn. gearing which can rapidly wear due to heavy vibration and dust, and the bearings were also im proved. But with very large mills the assembly of the rotor and stator was very difficult due to the need to obtain an exact air-gap between rotor and stator. The present invention uses a linear motor to overcome these problems.
