Title: Air conditioning lamp with concentric air inlet and outlet pipes - has ring of guide vanes for deflecting air into horizontal direction
Inventor: MOOG WALTER DIPL ING
IPC: F21V33/00
Filed: 1976-02-28
Abstract: Air conditioning lamp comprises a light source (1) concentrically surrounded at a distance by an air outlet pipe section (4) with a circular opening at its lower end, which is concentrically surrounded at a distance by an air inlet pipe section (6) with a circular opening at its lower end.

Title: Container pressure testing procedure - used for aluminium housings to receive electrical switches and employing blast waves stressing walls
Inventor: BUENGER GUSTAV ING GRAD
IPC: G01N3/12
Filed: 1977-01-27
Abstract: A disturbance centre created inside the container housing emits pressure waves which load the walls of the housing. This disturbance centre can be created by the ignition of an electric arc or by the ignition of explosive material. The blast which moves at supersonic speed flies through the housing and its shock waves strike the housing walls. The housing can be filled with water and the blast then fired through it. A wire of fixed dimensions can be stressed with a high current load and it then explodes and sends a pressure wave to load the walls.

Title: Bicycle derailleur type gear change - has sprocket halves pivotable to displace teeth axially to allow constant torque transmission
Inventor: BROWNING BRUCE W
IPC: B62M9/12
Filed: 1977-09-09
Abstract: A pair of sprocket sectors (35, 36) each having one or more sprocket wheel halves are respectively movable on a rotatable support. They are movable from a position where same diameter halves are in the same plane to form a full sprocket to a position where some teeth of one half move to align with teeth of a different diameter half or an associated different diameter full sprocket (34). This movement causes a bicycle chain (21) to transfer from one diameter sprocket to another whilst retaining driving engagement throughout. Each sector is pivoted at one end on the support about a pin (39a) common to both so that their remote ends move axially for gear changing in either diameter direction.

Patent DE-2818723-A1 (DE)
Inventor: HIRMANN GEORG
IPC: G01R13/06
Filed: 1978-04-28
Abstract: At a housing part (1), a stylus carrier (3) with a recording inset (4) is mounted by means of a hinge (2). The recording inset is kept raised away from the paper of a recording strip (8) by an armature (5) of a magnet (6) by means of a hook for as long as the circuit of the magnet, fed via conductors (13) and (14) is not interrupted by external means. The system, mounted on a circuitboard (9), contains a microswitch with a mechanical elastic-spring arrangement which is switched to normally-open contact via a plunger (10) in the readiness position of the stylus carrier. This connects two conductors (11) and (12) with one another. When the current is interrupted, the armature (5) is released and the stylus carrier (3) drops downward. At the same time, the switch connects the conductors (12) and (15). The carrier is returned manually. When the stylus carrier (3) is lifted up, the holding nose (7) pushes the armature (5) to the left from its perpendicular position in the example, whereupon the stylus carrier (3) is held fast by the armature (5) pivoting back. This recording system is capable of storing information. Its structure is simple and therefore operationally reliable and inexpensive. <IMAGE>

Title: Reciprocating air pump for artificial respiration - has time delay in control to prevent restart at high pressure
Inventor: SCHWIENBACHER GEORG
IPC: A61M16/00
Filed: 1978-05-19
Abstract: The battery operated electric motor (10) is coupled to a reduction gear box (11) which drives a rack (13). A piston rod (17) attached to the end of the rack carries a piston which works in a cylinder (18). The cylinder has an inlet valve (19) and a discharge valve (20) which is connected to a patient's face mask. A further outlet (21) from the cylinder leads to a pressure chamber (25) through a delay valve (26). The delay valve is such that an increase of pressure acts on the switch immediately and a decrease is delayed. The chamber contains a membrane which operates an electric switch which turns the motor on and off. The delay preents excessive pressures being developed and thus makes the pump safe for artificial respiration.
