Title: Small-bore driving between tunnel and basements - holes in tunnel wall lined up with bore axis and target entry to basement, abutment formed for drill
Inventor: HEYNE KARL-HEINZ DR ING
IPC: E03F3/04
Filed: 1976-12-22
Abstract: Small-bore driving between channel or tunnel and basements or cellars in adjoining buildings in municipal engineering. While the tunnel (2) is being driven, holes (5) are made in the tunnel wall during lining or subsequently. The axis of the bore to be driven runs through the centre of the holes. On the far side of the tunnel, opposite the bore, a firm abutment (6) is produced in the loose rock without affecting the wall of the main tunnel. A drill and thrust-bore unit are then positioned so that they thrust off the abutment and the bore axis passes through the centre of the opposite hole and through the target point in the basement or collar (4) to be entered. This is followed by driving through the intervening loose or firm ground and thrust-bore insertion of the tunnel casing or lining in the normal way. The abutment should consist of one or repeated injections of grout suspension or water glass (6).

Title: Catadioptric lens for electrostatic copier - incorporates dichroic filter for blue light for better reproduction of blue matter on white background
Inventor: ROWE STEPHEN HENRY
IPC: G03G15/043
Filed: 1977-01-21
Abstract: A catadioptric lens system has the reflecting surfaces formed by one or more dichroic filter layes (14E) which may also be arranged that they reflect all light except that within a selected wavelength range.

Title: Aqualung air supply valve - has pressure safety valve to close supply on minimum pressure level and enable manual by=pass to be opened
Inventor: GAROFALO GIANNI DR ING
IPC: B63C11/22
Filed: 1977-02-24
Abstract: The supply valve for the aqualung has a control valve (E) to link the air bottle to the mouthpiece connection (127). A secondary duct (6) leads to an emergency supply port (10) complete with emergency valve, which leads to a bypass duct (12) past the pressure control valve (22) which cuts off at a minimum set pressure. The valve can be used for double and single air bottles. When the minimum pressure is reached the air supply is cut off. the diver can then overide the valve by the emergency valve and knows that he has just sufficient air to return to the surface. The level of the cut off pressure is easily adjusted.

Title: Cleaning sulphur di:oxide-contg. waste gases - by washing with water contg. carboxylic acid and calcium chloride, then oxidising with air
Inventor: HOELTER HEINZ
IPC: B01D53/50
Filed: 1978-01-11
Abstract: The parent application described washing SO2 contg. waste gases with a liquid contg. carboxylic acid and additives, and oxidising with air in a separate vessel for several minutes.

Title: Dielectric welding of simple polyethylene wrapping film - with the aid of paper strips applied to weld sites
Inventor: UNLAND FRIEDHELM DIPL ING
IPC: B29C65/04
