Title: Zig zagging strip material by cramming - uses narrow channel whose decelerating bounding walls are formed of belts instead of rollers
Inventor: PERIERS GILBERT
IPC: B31F1/24
Filed: 1975-07-30
Abstract: The use of belts makes it possible to deal with rougher materials than before, and to incorporate a binder before the material passes through the machine. A fibrous material (1) taken direct from a carding comb, is steamed and sprinkled with a binder before it passes between rollers (7, 8; 50, 51) into the channel between the belts, here shown as three sets (14, 15; 16, 17; 18, 19). The belts are each formed of several strands, which are interlaced where the belts cross, and each pair of belts moves more slowly than the previous one, thus cramming the material into pleats. The pleats open slightly as they pass over a roller (58, inward suction from 77) to have an adhesive sprinkled between them (60). Leaving the roller, they close again and pass through a heater (62) which sets the adhesive. If the belts (14, 16, 18) on one side of the channel are moved slightly faster than those (15, 17, 19) on the other side, the pleats lean forward and lie on top of one another.

Patent DE-2633144-A1 (DE)
Title: Non-shear cascade toner for photocopier - uses static charge generated by cleaning brush on cascade buckets to remove excess toner
Inventor: KERSCHER REINHARD
IPC: G03G15/08
Filed: 1976-07-23
Abstract: The toner power is collected from the reservoir by a bucket chain on ann endless belt drive and lifted up to pour over the rotating drum to cover the charge image. The upper end of the belt pases a rotating brush which removes excess toner from outside the buckets and at the same time charges the buckets with static charge. The buckets pass close to the rotating drum and their charge removes any toner clinging to uncharged parts of the drum. A simple anti-smear control is thus obtained, which at the same time cleans the buckets to prvent toner falling in an uncontrolled way. The cleaning brush generates the static electricity in contact with the buckets.

Title: Measuring system for web movement speed - has no relative movement between web plane and transmitter and receiver
Inventor: LUUKKALA MAURI
IPC: G01S15/60
Filed: 1976-09-16
Abstract: On one side of the plane there is a transmitter which sends towards the web of material a narrow ultrasonic beam in the plane at an angle different from 90 deg.. This ultrasonic beam is reflected from the web after striking it at the preset angle. A receiver on one side of the plane has the same angular adjustment to the plane as the transmitter. It receives an ultrasonic signal reflected from the web of material and detects in the signal a Doppler frequency shift proportional to the speed of movement of the web.
Patent DE-2641749-A1 (DE)
Inventor: FASCHINGER GUENTHER DR
IPC: A63C5/056
Filed: 1976-09-16
Abstract: Adhesive film for skis, the outside of the film being impregnated with a ski wax, being used directly as a bottom coating or being covered with a second, wax-like film which exhibits special sliding properties. This relates both to adhesive wax and to downhill wax. This means that waxing, which has hitherto been a standard, time-consuming procedure, is no longer necessary, which represents an enormous improvement, especially for touring and cross-country skiing. It is furthermore possible to effect a very rapid conversion from uphill to downhill skiing, or from one type of snow to another, without having to scrape off an old coating, as one film is simply pulled off and another one stuck on. In addition, all fixedly adhering ski coatings which have been used to date and which are generally not particularly scrape-proof can be replenished. Decorative and advertising effects can be achieved by colouring or printing the adhesive film.
Patent DE-2651382-A1 (DE)
Title: Cathode sputtering target - with surface structure of grooves and groove wall slopes ensuring max. sputtering rate
Inventor: BOEHNKE RALF-DIETER
IPC: C23C14/34
Filed: 1976-11-11
Abstract: A cathode sputtering process to produce thin films on substrates uses a target with a regular surface structure. Ions with a vertical incidence hit the target at a definite angle of under 90 degrees. The surface is traversed by triangular grooves with an angle of slope alpha between 0-89 degrees (45 degrees). The atomisation rate and therefore the effectiveness of the process are increased because they depend on the angle of incidence of the ions. The erosion rate is very uniform. The structure can be applied to all types of targets (amorphous, polycrystalline or monocrystalline).

Abstract: 1528700 Electronic timer DAINI SEIKOSHA KK 25 Nov 1976 [27 Nov 1975] 49227/76 Heading G3T An electronic timer particularly for games, comprises down-counters 13, 14, 15, Fig. 3, the counter 15 serving to memorize a 10 minute half-time rest period while counters 13, 14 memorize 40 min and 20 min periods respectively. A switch 32 is operable to select either the counter 13 for timing each half of a football match or the counter 14 for timing basketball, and accordingly a display portion 5, Fig. 1, is activated to show either a footballer or basketball player in action. A digital display of remaining time is given and an alarm generator 23 (e.g. a buzzer) is activated when the display shows 00.00. The counting sequences are controlled by a shift register 22. With switch 32 closed to select basketball counter 14, a switch 18 is momentarily closed at the start of a timing period thus providing a shift pulse so that output Q 2 of SR 22 becomes "1". The resulting output of AND 30 releases a reset on counter 14 which begins counting 1 Hz pulses from a frequency divider 11 fed by an oscillator circuit 10. At the end of the 20 min period, the counter 14 produces a signal which causes activation of the alarm and shifts SR 22 output to Q 3 . Thereby counter 14 is reset and the reset on counter 15 is released so that it begins to count the 10 min interval at the end of which counter 15 likewise produces a signal to shift SR 22. Thereupon counter 14 begins to time the second half of the game. The counting of any period can be temporarily interrupted by opening a switch 12.
