Title: Dough panning - by moving pan laterally and longitudinally
Inventor: GUGLER VICTOR F
IPC: A21C9/08
Filed: 1973-07-12
Abstract: Two parallel sheets of dough are fed to a cutter which slices the dough into pairs of pieces which fall into a pan beneath the cutter.

Title: Plastics sheet slitting machine with parallel blades - has quickly adjusted fixed grooves to suit slight changes in blade spacings
Inventor: BRAUN SIEGFRIED
IPC: B26D1/03
Filed: 1973-07-31
Abstract: A cutting or slitting unit for dividing a plastics sheet into a large number of parallel strips comprises a beam or shaft, on which a large number of cutting blades are mounted with spacers between them; these blades co-operate with grooves of a fixed, helically grooved drum; this drum is constituted of a number of separate tubes all of equal dia. and having an external helical thread of pitch equal to the spacing of the cutting blades; these threads thus constitute grooves between them, which are pref. of trapezoidal or rectangular cross-section. Where a large number of very narrow (e.g., a few mm.) strips are to be cut from a wide plastics sheet, the number of blades and corresp. grooves can amt. to several hundred; the removal and replacement time when blades become worn is considerably reduced, in that only a relatively short length of the fixed drum needs to be assembled accurately opposite to the blades the next section of drum can be adjusted in its axial groove position by a slight relative rotation clock-wise or counter clock-wise relative to the first; i.e., the threads are not necessarily continuous around the entire drum. In this way the long fixed drum can be rapidly assembled to suit the spacing of a continuous row of many blades.

Title: Semi-automatic medical X-ray equipment - requires only one adjustment for programme of measurements
Inventor: FRANKE KURT DR-ING
IPC: A61B6/00
Filed: 1973-08-07
Abstract: A system is described for controlling a complete medical X-ray equipment suitable for producing a series of photographs. The X-ray gun is driven by a set of high voltage transformers which are switched on in a sequence determined by a stored program. The program required can be called up by the doctor or attendant in charge of the machine. The strength and duration of each burst of X-rays is set up according to the estimated subject characteristics, the first burst applied and an automatic exposure device behind the subject is used to estimate the optimal dose to produce good quality pictures. The current and voltage on the X-ray gun are controlled accordingly and the program automatically proceeds, to produce a film of pictures. Thence programs are usually available, namely long, normal and short, and the systems is organized for easy operation by the doctor or attendant.

Abstract: The data transmission circuit has a central timing generator repeatedly delivering a period of any time function and a spacing. The spacings are of equal widths with the pulses delivered to the transmission-reception line. Several transmit-receive stations are connected to the above line. Senders in the stations deliver to the line in accordance with the information to be sent, a time function delayed in the delay line by one period. Receivers in the stations separate any timing generator time functions from the phase shifted signal functions from the senders, and apply them to corresponding evaluating devices. The time functions used for data transmission are free from d.c.

Title: Sterilization of living cells - by focussing high frequency unidirectional magnetic or electrostatic fields on cancer cells
Inventor: HANSCHMANN GEB RUTKOWSKI AGNES
IPC: A61N5/00
Filed: 1974-02-01
Abstract: Very brief high-frequency unidirectional magnetic fields or electrostatic fields are focussed on a tumour to change the protein molecules produced in a cancer cell, which blocks the sound chromosomes of the surrounding tissue, so that they can be recognised by the white blood corpuscles and can be removed. This destroys viri and bacilli in the fluids of living cells without damaging the healthy cells. The high-frequency unidirectional magnetic fields can be focussed according to a program or through electronic amplification to an affected organ, by acupuncture methods where advisable, while the cell complex which has been dyed can be observed by an X-ray machine. Alternatively, these magnetic fields can be used to excite ultra-high molecular vibrations in the blue frequency range by ionisation and recombination through catalytic platinum grids. The resulting ultra oscillations in the water bath are used, after the current supply has been cut off, to destroy viri and enzymes in cancer cells.

Title: Fluid flow measurer using hydrodynamic drag forces - has flow actuated draglink which gives flow measure through transducer
Inventor: TAKANOYAMA TASAKU
IPC: G01F1/28

Abstract: Parallel to the fluid flow passage (1) there is positioned a larger bore channel (21) in which there is a drag link, and there is an aerodynamically actuated, component (26) which is axially disposed on the drag link. The flow of fluid generates a hydrodynamic drag force which causes movements of teh drag link against the bias components (29) at each end of the drag link (27). Measuring indications are derived from an end member consisting of a moving iron on the end of the drag link surrounded by a coil, the latter being positioned outside the bore channel.
