Inventor: BOGNAR ALAJOS
IPC: H01B17/42
Filed: 1976-12-16
Abstract: A plastic flexible h.v insulator for overhead lines is resistant to electrical erosion. The core of the insulator is fitted with an insulator screen. There is also a plastic layer between the screen and the core of the insulator. It is therefore resistant to polluted and moist environments. The insulator core (10) is embedded in the plastic layer (12) which forms an integrated unit with a plastic screen. The dia. of the screen varies alternately between a smaller (16) and a larger (14) screen. The screens are at right angles to the axis of the insulator. The thickness of the plastic layer surrounding the core is at least 2 mm.

Title: Internal combustion engine exhaust system and silencer - uses tubes with multiple bores to cool exhaust gas
Inventor: LEISTRITZ HANS KARL DR
IPC: F01N13/18
Filed: 1977-07-25
Abstract: A silencer forming part of the exhaust system of an internal combustion engine consists of two concentric tubes (51, 52). These tubes are joined by radial walls (55) which extend longitudinally so that the annular space between the tubes is divided into a number of separate compartments (5). A cooling fluid flows in these compartments (5) in the opposite direction to the flow of gas in the central bore (50). The outer wall of the outer tube (52) has a number of radial fins (56) which also extend longitudinally. These fins help to dissipate the heat which has been transferred to the cooling medium by convection and radiation.

Title: Sepn. of liq.-liq. dispersions - having pre-coalescing zone followed by packed section in which dispersion takes wedge shaped profile as phase sepn. occurs
Inventor: WIESNER PAUL
IPC: B01D17/04
Filed: 1978-03-10
Abstract: Liquid - liquid dispersions are sepd. in system with precoalescing space. The initial mixt. should have a dispersed phase fraction of 0.28-0.65. Residence tiem inprecoalescer should be 10 to 30 sec. After leaving the pre-coalescer the mixt. enters a separator. The sepn. space consists of an array of small spaces with vertical and horizontal divisions. The dimensions of the spaces are selected so that when the liq. flows through, the resulting pressure drop causes the mixt. to assume a wedge shape as the pure phases separate out. For sepg. liq. mixts. with a dispersed phase compsn. of 0.28-0.65 gives a cheap compact settler construction.

Title: Split contact electrode for resistance welding - with contact zones designed elastically deformable to absorb tolerances
Inventor: ZIMMER ERNST ING GRAD
IPC: B23K11/30
Filed: 1978-05-19
Abstract: A split contact electrode for the electric current supply during resistance welding, specially for tubular workpieces is designed with a special configuration of the contacting ends. They are contoured or lightened in such a way that they are elastically deformable. This ensures their good fit around a workpiece independent of tolerances. The result is a more homogeneous welded seem. Specifically a lide to a tube by resistance welding from a transformer, the tube is held by a split contact electrode and a welding electrode is applied to the lid. The contacting faces of the two halves of the electrode can be chamfered at both outside ends or have semicircular cut-outs leaving only a narrow deformable contact zone near the workpieces. Additional elasticity can be conferred by boring holes through the end parts on both sides.

Title: Regulating vehicle speed against separation distance - using variable separation distance speed relation involving time constant and delays
Inventor: ACKERMANN FRITZ DIPL PHYS
IPC: G08G1/16
Filed: 1978-08-01
Abstract: The method is for adjusting the speed (V1) of a vehicle according to its distance (a) from a second vehicle involves measuring the speeds (V1, V2) of both vehicles and their separation distance. It enables adjustment of the speed according to a distance dependent on vehicle speeds rather than a fixed distance as with conventional methods. This can be used to achieve a laminar traffic flow. The distance (ak) is derived from a quadratic equation involving a time constant (T) vehicle delay values and a defined distance (ao). The required speed is then derived from a linear equation.

Title: ABS continuous prodn. by bulk graft polymerisation - after preheating under pressure to give specified monomer conversion and increase rubber effectiveness
Inventor: DOKUKINA LJUDMILA FEDOROVNA
IPC: C08F279/04
Filed: 1978-08-21
Abstract: Continuous prodn. of ABS by (graft) polymerisation of a soln. of butadiene rubber (I) in a mixt. of styrene (II) and acrylonitrile (III) monomers is carried out at 80-200 degrees C., followed by removal of volatiles from the ABS melt at 200-230 degrees C. and 10-20 torr. The novelty is that the (I) soln. is heated, before polymerisation, at 60-100 degrees C. and a pressure exceeding the (III) vapour pressure at the temp. used until the degree of conversion of the monomers attained is 3-6%. ABS is widely used for the mfr. of pts. and housings for radio and TV receivers, telephone equipment, typewriters and calculators, refrigerator linings, vehicles pts., tubes, etc. The prod. has the required physical-mechanical properties and a lower copolymer content than usual, which increases its effectiveness.
