Title: Transmission system for TV telephones - divides picture into lines with sawtooth scan scan with each frame transmitted consecutively
Inventor: WENDLAND BRODER DR ING
IPC: H04N3/34
Filed: 1974-01-19
Abstract: Lines of the two fields are interlaced, and the scanning beam is wobbled transversally to the line direction. The wobbling is done by a saw-tooth voltage, whose peak-to-peak amplitude is such, that adjacent lines in a full picture partly overlap; picture points lie on the rising flanks of the saw-tooth curve, and the scanning speed is nearly constant during the rising flank of a saw-tooth. The angle between the line direction and the saw-tooth rising flank is approx 45 deg. The angle between the line deflection and the saw-tooth deflection is always differnet from 90 deg.
Patent DE-2403924-A1 (DE)
Inventor: MASSON YVES
IPC: B60C9/18
Filed: 1974-01-28
Abstract: This invention relates to low-profile vehicle tires whose cross-sectional proportions of height to width are equal to or less than 0.8 to 1 and of the kind comprising a carcass having side-walls and a crown, a tread and a reinforcing breaker between the carcass crown and the tread. In the invention the breaker extends transversely for a width which is at least equal to the tread width and has a shallow central section and two deep lateral sections. The shallow central section has a width between half and two-thirds of the tread width and a substantially uniform depth not greater than three times the carcass crown depth. At least the lateral sections of the breaker are made of an anisotropic rubbery mixture having a very high modulus of elasticity in the circumferential direction of the tire. This modulus is greater than 15 kg/cm2 at 10% extension. The depth of the lateral sections of the breaker is between two to three times the depth of the central section of the breaker.

Title: Profiled sections from cold rolled sheet - sections reinforced by folding sheet back on itself over inlaid strip
Inventor: WARM HERMANN
IPC: E04C3/04
Filed: 1974-05-07
Abstract: I section profile or beam (1) is made by cold rolling sheet metal. The top and bottom portions of the I section are made by first folding the sheet at right angles to the central section and then back on itself to pass back over the central section before being once more folded back underneath itself to finish adjacent the central section. Strips of sheet materla (2) are interposed between the double folded top and bottom parts of the I section to reinforce it. Z and channel sections are shown fabricated in like manner and in a modification the inlaid strip is omitted and reinforcement is achieved by making a further fold in the sheet material to produce three layers of sheet in the folded parts.

Title: Deep drawn thermoplastic lining for porous cup - is held on die face by pressure to reduce stretch
IPC: B29C51/10
Filed: 1974-06-14
Abstract: An apparatus for deep-drawing thermoplastics sheet, esp. very thin sheet for forming a lining to a porous vessel such as a paper cup, comprises a plunger die, for forming the preliminary shape, followed by a differential pressure stage to draw the sheet into a close fit inside the cup, equipment is also provided to make the sheet 'adhere' temporarily to the surface of the die, pref at least until the differential pressure acts on the sheet, more specifically until the sheet is in contact with the bottom of the cup. Prefthis equipment consists of opening eg. in a porous plug in the face of the die, which are subjected to vacuum to hold the sheet on the die, and a counter-die is temporarily pressed against the lower face of the sheet. The minimum thickness of sheet can be reduced, since differential drawing of the sheet, and thus differences in thickness, are minimised by pressing it into the die.

Title: Sailing boat variable stress hollow mast - with internal pressure strips tightened from outside using threaded screws
Inventor: SCHMERLING KARL H
IPC: B63B15/00
Filed: 1975-09-24
Abstract: The hollow mast is made from aluminium, or light alloy, or from suitable plastics. One edge has an open groove in whih the sail is threaded. The inside faces are fitted with pressure strips (2) running up the mast and secured by screws (3) tightened from outside the mast. The selective tightening of the screws up the mast alters the tension in the mast and sets its optimum flexibility. This allows bes use of the sail shape. The strips are held on elastic mountings, so that the screw heads are always pulled flat into the mast. The strips do not add appreciably to the weight of the mast.

Title: Data processing with hierarchically arranged multistage storage - with two lowest storage stages consisting of all data main store and buffer store for selected data
Inventor: SCHNEIDER PETER DR PHIL
IPC: G06F9/46
Filed: 1975-09-25
Abstract: When a process is in progress and a request for access to the buffer store (SSP) is made, the selected storage group address is recorded in the control unit (SST) by intermediate storage of its address, so that the storage area of the process is determined. When a process is changed, the group address is transferred to the main store (HSP). When the process is again activated by a processor of the data processing installation (ZP), the information is first read out from the main store on the storage area used up to now, and corresponding groups in the main store are sequentially read out and transferred to the buffer store, if they have been displaced by processing of other processes.
