Title: Control system for tunnelling machine rotary cutter - has cutter tilted at angle to plane of rotation to reduce wear
Inventor: HORST HEINZ
IPC: E21D9/10
Filed: 1979-02-24
Abstract: The rotary cutter for a tunnelling machine or other rock cutting machine has a cutting edge which is triangular in section and which makes an ellipse shaped cut during rotation. In order to reduce wear and load on the bearings, the cutter is angled so that the axis of the cut is at an angle to the normal direction of cut. In the place of the circle having a radius through which the cutting tip passes, the edge of the cutter is titled through an angle which lies behind the radius, compared with the direction of rotation.

Title: Image transfer system based on colourless basic solvent dyes - mixed with a wax or resin binder, which develop colours in contact with an acid or reducing developer
Inventor: TUTTY GEOFFREY COLIN
IPC: B41M5/30
Filed: 1979-02-26
Abstract: Colour developer system for image transfer units consists of (a) a colourless solvent dye which is a free base of a basic dye e.g. of the diphenylmethane, triphenylmethane, triarylmethane, xanthene, azo or phenazine type, which develops a colour on reaction and/or contact with an acidic and/or reducing developing agent, and (b) a wax or resin binder which does not develop the dye base, in (c) a non-developing solvent. After mixing, the solvent may be removed e.g. by spray drying to give particulate prod. The binder resins used may be e.g. acrylic, polystyrene, ethylcellulose, chlorinated rubber, saturated polyesters, co- and terpolymers of PVC, PVA, vinyl toluene, butadiene, acrylonitrile, etc. The compsns. have a wide range of application in image transfer units which are activated by imagewise application of pressure, heat, light or electrical discharge to cause contact of the colourless basic dye with the developing agent which is e.g. an organic acid, natural or synthetic tannin, etc. Typical application for the compsns. are in carbon paper, overhead projector transparencies, etc.

IPC: H01R25/14
Filed: 1979-03-15
Abstract: Power distribution system uses a 'U'-shaped bus-bar, a mobile power take-off adaptor and a similar power input unit. The system is fully protected against accidental contact by the user. The power take-off adaptor makes contact on the inside of the bus-bar and if the adaptor's output contacts are not in use they are covered and interlocked. The current carrying rails of the bus-bar are protected in an insulator and the power take-off adaptor has an outer insulator cover. All contact between adaptor contacts and live bus are spring-loaded. Only when contact is made between bus and adaptor, as the adaptor is clipped into place, are the current carrying contacts exposed mechanically to make connection.

Title: Automatic fuel supply for light heating oil - has semiconductor thermostat for inside temp. and electronic control for governor control mechanism
Inventor: BOECKING HEINZ
IPC: F23N1/02
Filed: 1979-04-14
Abstract: The governor automatically ensures that the oil/air mix in the burner is at an optimum level. A semiconductor room-thermostat with an electronic controller regulates the control mechanism of the governor. A servomotor rotates a cam that operates a control element in the oil supply regulator. An arresting magnet forms a second setting unit with the servomotor. When in its not arrested position, this second setting unit closes the control element of the oil supply regulator in any position of the cam when no voltage is applied to te servomotor. When in its arrested position, this second setting unit allows the servomotor with its cam to come into operation.

Title: Boron tri:chloride prodn. by chlorinating borate ester - in presence of free radical initiator, reducing phosgene formation (NL 30.9.80)
Inventor: DELUE NORMAN RAY
IPC: C01B35/06
Filed: 1980-03-24
Abstract: In the prodn. of BCl3 by chlorinating borate esters (I), a reactor is chaged with Cl2 and (I) in 5.5-7.5:1 (5.75-6.75:1) molar ratio and allowed to react in the presence of free radical initiator (II) at 20-100 (40-90, esp. 60-80) degrees C with simultaneous removal of the reaction prods. in the gaseous state. Reaction is carried out continuously and the liquid mixt. is also removed from the reactor and distilled, the distillate being returned to the reactor. The amt. of liq. removed is 4-20 (6-15, esp. 8-12) vol.% of the total per hour. The B content of the recycled distillate is adjusted by adding (I). Reaction is carried out at 1.01-2.43 (1.01-2.13) bar. An inert liquid organic solvent (CCl4) can be added, this being removed with the gaseous prod., condensed and recycled. BCl3 has many industrial uses, e.g. as intermediates for other B cpds. (diboranes, refractory metal borides TiB2), as refrigerant and as catalyst for Grignard reactions. The amt. of COCl2 formed as by-prod. is reduced considerably.

Title: Airbag protection for car driver - has shaped cushion inflated over top of steering to protect head
Inventor: PILATZKI BERND
IPC: B60R21/231
Filed: 1980-05-21
Abstract: The car driver protection has a shaped cushion inflated to cover the top part of the steering wheel whose centre is padded. The cushion protects the head of the driver on impact and does not restrict the view through the windscreen. It is inflated automatically by an impact sensor and remains inflated until a release valve is opened. The cushion replaces the larger airbag which gives a restricted view through the windscreen, especially when inadvertently released while the car is travelling. The smaller cushion is rapidly inflated without the sudden pressure increase inside the vehicle associated with the larger airbag.

Title: Construction system with multi-surface skeleton members - uses profiled struts and beams and special clips to fix wall panels in skeleton
Inventor: RENSCH EBERHARD G
IPC: E04C3/07

Abstract: The system uses a variety of sections to form a skeleton framework which supports wall panels and thermal insulation. A typical section consists of two channel sections joined by an angle section so that the webs of the channel sections are mutually perpendicular. The horizontal web (15a) supports a panel of thermal insulation (4), whilst the horizontal flange supports a block (30) which in turn supports a wall panel (29). The wall panel is secured by a special clip (24) which fits over the turned-over edge of the section and around the lower edge of the panel. A small channel section extension of the clip fits over the turned edge of a second section which covers the insulation panel (4).

Title: Weather shield for vehicle opening side windows - has hooked flaps on shield edge which project through slots in window weather strip to sit between strip and window frame
Inventor: SPLITHOFF THEODOR
IPC: B60H1/24
Filed: 1980-05-27
Abstract: The vehicle side window weather shield has a rim (6) round its edge which fits into the 'U'shaped window weather strip (5), and is provided with one or more extension flaps (7) whose ends are bent over to form hooks. These flaps (7) project through slots in the weather strip so that the hooks fit between the strip (5) and the window frame (4). The plastics of the rim (6) is sufficiently thin to allow the window (2) to be wound fully into the frame without causing damage to the strip (5) or the winding mechanism. To avoid vibration during travel a distance piece on the weather shield end clips round the window frame to provide a simple but safe fitting.

Title: Impermeable surface prepn. on polyethylene fuel tanks - by HF energising inert gas at low pressure in tank
Inventor: LAATSCH HANS-DIETER DIPL ING
IPC: B05B5/08
Filed: 1980-07-19
Abstract: Surfaces of articles, esp. the interior surfaces of plastic fuel tanks with the properties of polythene, are treated with a medium which is normally inert; the medium is fed into an evacuated chamber contg. the article and is energised into a state of plasma at reduced gas pressure. A vehicle fuel tank of polythene is connected to a vacuum pump, to a valve controlling the feed of gas, and to a gas pressure valve. The tank is placed inside a partically evacuated chamber to prevent the tank from collapsing under external pressure. A condenser plate lies each side of the tank, the plates are connected to a h/f generator and energised at suitable level to strike a plasma state. Impervious barrier film is produced on polymer surface, medium only splits off radicles when energised, process is easily controlled e.g. by pressure or supply of gas, energy intensity or duration.
