Title: Holographic storage of binary coded information - uses intensity modulation of object wave compensating fluctuation of mean radiation intensity
Inventor: KIEMLE HORST DR-ING
IPC: G11C13/04
Filed: 1973-11-05
Abstract: The intensity of the object wave in the holographic storage device is modulated by the information to be stored. The volume of information to be stored in a hologram is predetermined by the number of vaster positions of a point vaster and is evaluated with regard to the number of binary ones or binary zeros assigned to the number of vaster positions. In dependence on the evaluation with the aid of suitable control means (AM') either the intensity of the reference wave (BW) during the recording of a specific value or the size of an additional exposure time is determined only for the reference wave.

Title: Non skid brake for vehicle or machine parts - with repetitive brake impulses added to steady basic brake force
Inventor: SIEKE HELMUT DIPL ING
IPC: B60T8/32
Filed: 1975-02-03
Abstract: The anti-blocking brake control monitors the rotation of the wheels as the brake pressure is increased. When a set level of retardation is reached, the brake pressure is maintained at a set level while a vibrating braking component is superimposed on it. The level of the vibrations is such that it takes the brakes from the steady level to just below the blocking level. The frequency of the vibration depends on the speed of the vehicle and the amount of braking required. The vibration can be produced using a hydraulic servo. The whole brake control system can then be simplified.

Title: Double-acting piston for injection mould closure - has through passages opened or closed by rotatable valve disc
Inventor: JAMANN HELMUT
IPC: B29C45/67
Filed: 1975-10-02
Abstract: A double-acting piston for the closure unit of an injection moulding machine has a number of ducts, pref. disposed around a circle, to permit flow of pressurised fluid from one side of the piston to the other. These ducts through the piston can be opened or closed by means of a perforated plate, rotationally mounted on the ace of the piston and itself having perforations which can come into register with the ducts, thus permitting free passage of fluid through the ducts, or alternatively can be displaced circumferentially so that the plate blocks the ducts. Pref., the limited rotation between the open and closed positions of the perforated plate is produced as follows: the plate has an inward projection, which thus has two radial shoulders or surfaces sub-dividing the space between this perforated plate and its bearing into two chambers. Either of these chambers can be pressurised with fluid through a duct mounted in the piston, so that the perforated plate is rotated clockwise or counter-clockwise, depending upon which chamber is pressurised. Flow of fluid through the piston with equal pressures on both sides is obtd. with minimum disturbance and thus minimum heat generation.

Title: Conveying film web from an extruder nozzle to a thermoforming station - by tapping the film edges and advancing web by relative movement of extruder and forming machine
Inventor: KIEFER GUENTHER
IPC: B29C48/50
Filed: 1975-11-08
Abstract: A film web is guided from an extruder nozzle to the forming station of a thermoforming machine by connecting the edges of the film with tapes (to hold and guide the web). Advance of the film is effected by a relative movement between extruder and the thermoforming machine. Relative movement of nozzle and the tapes is caused as the extruder is slowly moved back. The tapes are also displaced, during the advance movement of the extruder, w.r.t. the nozzle, at the same rate. Method is used in continuous film extrusion processes where the film issues from a wide-slot die and is immediately passed to an intermittently operating thermoforming machine which is coupled with the extruder. E.g., mfr. of plastics containers such as beakers. Risk of thickness variations of the film being extruded/conveyed is minimised.
