Patent DE-2845868-A1 (DE)
Title: Push=on cable end closure - with sleeve or insulating elastomer with axial reinforcing elements
Inventor: HOLLAND KARLHEINZ ING GRAD
IPC: H02G15/06
Filed: 1978-10-21
Abstract: The end of a power cable with a plastic insulation consists of a sleeve, made of an insulating elastomer, which is pushed over the core and the insulation up to a step with the metal sheath. The sleeve has been reinforced by embedded elements parallel to the axis, or inclined to the axis, or wound in a large-pitch spiral around the axis. These cements are made of an insulating material and can be rods, fibres or bundles of fibres. In the case of rods, they have a high resistance in tension and compression and are pref. curved in opposite directions in two concentric rings. In the case of fibres, these can form cylindrical or conical sheaths which are fixed at both ends. Such a cable closure is rigid in the axial directions, has a high flexural strength at right angles to the axial direction, and remains elastic in the radial direction.

Title: Bonding coloured pigment to phosphor particles using PVA binder - crosslinked with diazo cpd. to increase adhesion
Inventor: BOLZ BRUNO
IPC: C09K11/02
Filed: 1979-02-09
Abstract: In the bonding of coloured pigments (I) to the surface of phosphor particles (II) using a suspension contg. (I), (II) and a binder, PVA crosslinked with a diazo cpd. (III) is used as binder. The process is specified for use in the prodn. of colour TV screens. The adhesion of (I) to the surface of (II) is improved, preventing loss of contrast in areas lacking (I) and undesirable enrichment of (I) in the circulating suspension, which would make it difficult to process the recycled (II). An aq. acid, PVA suspension contg. (III) is used and crosslinking is effected by rendering it alkaline. (III) is a diazonium salt of a sulphonic acid.

Title: Computerised focus control for process camera - has separate stepping motors for each lens element mounted on carriage
Inventor: WALTER HERMANN DR RER NAT
IPC: G02B7/10
Filed: 1979-04-27
Abstract: The focus control is for a computer controlled process camera and has the lens elements (1, 2) mounted on the lens carriage (8) on independent stepping motors (4, 5) and with the carriage moved by a further motor (10). The required motor settings are stored in the address and the motors are controlled separately for a rapid setting.

Title: Compensating temp.-dependent measurement errors - using balancing force acting on lever with components possessing different coeffts. of expansion
Inventor: KEMMLER LOTHAR
IPC: G12B7/00
Filed: 1980-05-09
Abstract: An arrangement for compensation of temp. dependent measurement errors in measurement equipment operates on the force balancing principle whereby a temp. dependent force, esp. a magnetic force, is applied to a force transfer lever arm. It enables simple effective compensation. The effective length (a) of the lever arm, on which the temp. dependent force (M) acts, can be varied inversely w.r.t. the known variation in the magnitude of the force with temp. The effective lever arm length variation is achieved by a lever system of two or more interacting levers of different materials with different thermal expansion coefficients. There is a longer lever (1) with a higher thermal expansion coefficient and a shorter one (2) with a lower coefficient. The force acts on the free end (7) of the shorter lever (2).

Title: Hazard warning flashers for vehicles - are activated automatically by impact force on collision
Inventor: FRICKEL KURT
IPC: B60Q1/46
Filed: 1980-06-12
Abstract: The circuit achieves automatic switching on of the warning flashers in the event of a collision. It is applicable to flasher circuits which are already equipped with a manually operated switch for the same purpose. Connected with the flasher unit is a switch with an inertia loaded contact. In the event of sudden acceleration or retardation this loaded contact moves from its normal open position to a closed state and connects the supply from the battery to the flasher unit, and through this unit to such turn indicator lamps which are undamaged. The inertia switch is pref. arranged to respond to an impulse force from any direction. The magnitude of the rate of change of velocity required for operation can be preset to the normal operating condition of the vehicle.

Title: Machine to weld rings to valve discs - with swivelling pocket for rings acting as one-by-one distributor, used for internal combustion engines (SE 08.02.82)
Inventor: DUDKO DANIIL ANDREEVIC
IPC: B23K13/00
Filed: 1980-08-04
Abstract: A machine to weld rings to the seating areas of disc valves for internal combustion engines has two separate inclined gravity chutes which pass valves and rings into a vertical tube above a power cylinder. This tube is arranged below a high-frequency inductor with a central 3-jaw chuck. The tube receives a valve which has been turned over to sit with its disc on a plate with a rim of the power cylinder rod. The rings first drop in a swivelling pocket with a retainer rim which tips them by a power cylinder over the valve stem on the valve disc. This creates a simple and functionally reliable welding ring which saves time and uses a swivelling pocket for the dual functions of one-by-one sepn. and of tipping on the disc.
