Title: Combustion of motor fuels - with mixts. of oxygen, air and exhaust gas to ensure complete oxidn. and reduce pollution
Inventor: VIERLING DONALD E
IPC: F02M25/00
Filed: 1976-06-23
Abstract: Oxidn. of fuels is effected in the combustion chamber of a machine, with a mixt. of oxygen, air and recirculated exhaust gasm the flow of each being controlled to give wt. ratios of 4-16% oxygen, 85-25% air and 11-59% exhaust gas, which are maintained during the whole operation of the machine. Used esp. for combustion of petrol in vehicle motion. Content of toxic substances in the exhaust gas is reduced, as well as the total amt. emitted. Any CP or hydrocarbons in the exhaust gases are oxidised on recycling. No loss of engine efficiency or increase in fuel consumption occurs and the equipment is relatively cheap to instal.

Title: Belt conveyor drive system - uses auxiliary drive belt in contact with main belt held by vacuum applied between two belts
Inventor: FISCHER HANS DIPL ING
IPC: B65G23/19
Filed: 1976-11-15
Abstract: The conveyor includes a belt and driving drum and driving rollers and intermediate drives provided with a number of rotating units. The driving force transmitted by the driving drum and the driving rollers and the intermediate drives on the driven belt is increased by additional suction forces.

Title: Easily actuated nut cracker with simple design - has clamping faces set inclined to handle with one face movable by thumb
Inventor: SCHMELOW HARALD MARTIN
IPC: A47J43/26
Filed: 1977-01-25
Abstract: The nut cracker is designed to open nuts with a minimum of force. It comprises clamping faces set at a specific angle to the handles and having a restricted path.

Title: Rotary engine with orbiting piston - has motion controlled by gears mounted in casing, piston and on crankshaft
Inventor: TODOROVIC VUKASIN
IPC: F01C1/32
Filed: 1977-03-24
Abstract: The five lobed piston (30) is provided with an internally toothed wheel (54) which meshes with a gear wheel (48) mounted eccentrically on the crankshaft. The gear wheel (48) is provided with two rows of teeth and the second row of teeth meshes with an internal gear mounted on the end face of the casing. The numbers of teeth are so chosen that the motion imparted to the piston is such that its centre line moves in a circular path but the piston itself does not rotate. This motion causes the vanes (60) to oscillate radially and the volumes (62) between the vanes to alternately expand and contract.

Title: Head cover for use in surgical operating area - has channels beneath hood connected to vacuum source for withdrawal of bacterial matter
Inventor: DUVLIS ZINON DR MED
IPC: A61B46/27
Filed: 1977-05-04
Abstract: The air flow system is used for producing a clean space above a medical, esp. surgical operation area. The region is not supplied directly with purified air by a conventional air supply because it would form an obstruction to the surgeons. The clean condition space is produced by a system of channels placed externally on the head covering hood. The channels are connected to a vacuum or pressure source and the channels are connected to the ambient air close to the hood outside surface. The channel systems can be also connected to a heat supply system the head, neck and face are covered but the eyes are left free.

Title: Discriminator testing validity of banknotes - has belt carrying banknotes against rotating drum past detector head and separating genuine and counterfeit notes
Inventor: KOMURA AKIO DIPL ING
IPC: G07D7/00
Filed: 1977-05-21
Abstract: The system for differentiating between genuine and false bank-notes or similar documents includes transport for a repeat checking and it reduces the period required for the second test. The segregation is carried out by inserting the note through inlet (11) for conveying on the surface of cylinder (12) driven by motor (15). During the motion of the note, its size, imprint or magnetic image are sensed by detector (16). If the note passes as a genuine one, it is forwarded to outlet (17) for collection in box (18). The rollers (142-144) are set outside cylinder (12) to ensure that the endless belt (13) covers a greater part of the cylinder, and one of the rollers is driven to impart motion to the belt. Bank-note insertion detectors (20) and guide blocks (21, 22) at the inlet and outlet control the note motion. The signals from detector (16) control the shift of the guide blocks for allowing the inlet or outlet of the banknotes.

Title: Initial charging of pebble bed reactor - with core rods fully inserted and side reflector rods fully withdrawn
Inventor: BROMKAMP KARL-HEINZ DIPL ING D
IPC: G21C19/20
Filed: 1977-08-10
Abstract: A method of introducing the first fuel charge for a gas-cooled high-temp. reactor of the pebble bed type with adsorber rods both in the core and in the side reflector is as follows. The spherical elements are introduced into the core with the core rods fully inserted and the reflector rods fully withdrawn. Charging is carried out in a series of steps using the predetermined ratios of elements of different types, the core being maintained sub-critical throughout the entire charging operation. By having the core rods fully inserted at the commencement of charging, no compacting of the spherical pebble bed elements takes place, which could result in damage to the core rods or to the elements. The method results in a high degree of safety at all times during the first charging.
