Title: Ski stick handle with adjustable loop - includes wedge shaped link fitting into narrowing channel leading to loop outlet
Inventor: LENHART KARL
IPC: A63C11/22
Filed: 1978-07-07
Abstract: The ski stick handle has an adjustable grip loop made from leather, plastics or similar material with both ends attached in a recess of the handle. The size of the loop is adjustable, and the recess if formed as a channel reducing towards the loop outlet opening (13). A wedge shaped link (15) between the two loop end sections matches the narrowing of the channel and reduces in the direction towards the loop outlet opening. At least one loop end is accessible from the outside of the grip handle (10). The wedge shaped link is made to fit in shape to one of the two loop end sections.
Patent DE-2843788-A1 (DE)
Inventor: KNECHT WILLY
IPC: B23B51/04
Filed: 1978-10-06
Abstract: Two square indexable inserts with rounded corners are held with positive end angles (A, B) in the drill shank (1). The inner indexable insert (6) does not project with its end cutting edge (60) beyond the drill axis (Z). The following measures serve to distribute the load uniformly:   - The most central corner (71) of the end cutting edge (70) of the outer indexable insert (7) is less than an insert edge length away from the drill axis (Z). - The outer indexable insert (7) has an axial back offset (R) relative to the inner indexable insert (6). - The end angle (B) of the outer indexable insert (7) is less than the end angle (A) of the inner indexable insert (6). The radial angle of the inner indexable insert (6) is less than that of the outer indexable insert (7).   These measures also lead to better centring and higher capacity. <IMAGE>

Title: Electric machine stator end windings supporting arrangement - has two insulating rings secured together with inner one mounted coaxially with stator core inner bore
Inventor: CHUTOREZKIJ GARRI MICHAJLOVITS
IPC: H02K3/50
Filed: 1978-11-10
Abstract: The arrangement for supporting stator end windings of an electric machine comprises a rigid inner ring (8) and an outer ring (12) both rings being made of electrically insulating material. The inner ring (8) is mounted coaxially with the inner bore of the stator core (1) and supports the end portions of a stator bar winding, and the outer ring (12) externally embraces these end portions. Both rings are mounted and secured together along the head portions (5) of end windings. The inner ring (8) is attached to Z-shaped members (15) arranged adjacent to the end portions and preventing the inner ring from axial displacements relative to the end portions. This is achieved due to the fact that the projection (18) of each Z-shaped member, facing the end surface of the core (1), is positioned between winding bars at their outlet from core slots (2) and is rigidly connected with a bracket (20) movably associated with a clamping plate (6) of the core (1) and attached to the outer ring (12). Thus, the arrangement for supporting the end windings and the end windings themselves makes up a rigid integral unit resistive to the action of vibrations arising during operation of the electric machine and axially displaceable under thermal expansion of the winding bars.

Title: Constant voltage power supply for unstabilised DC source - has voltage drop compensation for stabilised supply load variations using transistor with base coupled to supply terminal
Inventor: WILHELM WILHELM DR ING
IPC: G05F3/30
Filed: 1978-11-13
Abstract: The stabilised supply is typically for logic circuit application in which there may be sudden current changes, but in which attendant voltage swings must be avoided. The required accuracy can be achieved by alterations to the stabiliser set out in Parent Cert. No. 2533199. These alterations comprise the addition of an identical transistor (T6) in the collector lead of the output transistor (T5) and a further transistor (T4) with its collector-emitter in the voltage divider circuit (D21, D22, T3), and its base connected to the emitter-collector common point of the power transistor (T5, T6). The base of the additional power transistor (T6) is connected to the supply pole (Uv) by a matched resistor (R5). The output current proportional voltage drop in the emitter follower transistor (T5) is reflected in the extra transistor (T6). The voltage drop in the latter is then added with inverse sign to the base of the emitter follower (T5). The result is a stabiliser with very low apparent internal resistance.

Abstract: The surfboard is of divided construction and may have sails. It has a hull in mirror-image halves joined along the centre plane. The mating faces house threaded bushes for clamping bolts which either hold the halves together or, with the faces turned up, secure a rigid buoyant connecting-deck structure turning the board into a catamaran. The structure has transverse spars used as strength- and securing-members and a central mast and dagger-board housings like the hull. The bushes, and bolts, may extend right through the hull halves. The mating faces may embody dowel pins and sockets.

Title: Connecting arrangement for vehicle reflector and headlamp glass - comprises sealing gasket and bayonet type coupling readily detachable
Inventor: HENKE GEORG ING GRAD
IPC: F21V17/00
Filed: 1979-03-22
Abstract: The seal between the lamp glass (10) and the reflector (11) permits ready separation of these parts. It incorporates an elastic seal or gasket, and bayonet type connectors for holding the main parts in position. In a typical design a circumferential flange (15) on the lamp glass has button shaped projections (17, 18). The projections fit through slots in the reflector. Turning the reflector or glass through a small angle then causes the button head (18) to grip the back of the reflector. The gasket ring (19) fits between the glass and reflector flanges, and is slightly compressed when the parts are coupled together. Alternative designs employ a gasket ring with buttons on each side which fit into slots in both reflector and glass.

Title: Automatic sterilisation of tubing - having supply of disinfectant which is pulsed into tubing followed by flush of sterile water
Inventor: WURSTER HELMUT DIPL ING
IPC: A61L2/18
Filed: 1979-09-22
Abstract: Appts. is for sterilising pipes and tubing using a disinfectant which is pumped from a vessel using compressed air into the tubing. The disinfectant is pumped as a series of pulses down the tube. Compressed air is applied to the vessel in pulses and this is followed up by opening a valve into the tubing. The disinfectant thus flows as a series of pulses down the tube. It is followed by a pulse of air and finally a rinse of sterile water. The appts. is for use on tubes and pipes in medical equipment. It uses less disinfectant than a continuous pumped system, is easier to operate and can be fully automated.

Title: IC engine with rotor - has axially reciprocating pistons extending displacement bodies into liq.-filled space so buoyancy produces rotation
Inventor: PACHTEU RUDOLF
IPC: F02B71/00
Filed: 1979-12-21
Abstract: The engine comprises a rotor (1) containing a number of circumferentially spaced axial cylinders each with a piston (3) carrying a displacement body (2). Ignition of an explosive mixt. in the lowermost cylinder forces the displacement body into a liq.-filled chamber (4) and the buoyancy resulting from the displacement produces an upward force to rotate the rotor. Near its uppermost position, the piston (3) with body (2) is returned by a cam face, and compression takes place. The process is repeated when the cylinder again reaches its lowermost position.

Title: Dual function pacemaker circuit - has two pacemakers with slightly different frequencies and remote control switch
Inventor: JUESGEN WOLFGANG DR MED
IPC: A61N1/368
Filed: 1980-04-18
Abstract: The pacemaker circuit is suitable for cases of disturbed cardiac rhythm due to either disorders of the specialised cells responsible for the initiation of stimulating pulses or of the neuro-muscular cells responsible for the conduction of these impulses. In order to achieve this task two pacemakers are included in this circuit. The first, atrium inhibited pacemaker has a frequency of 80 impulses per minute whilst the second slightly delayed atrium controlled pacemaker has a frequency of 75 impulses per minute. The output (4) of the first pacemaker (3) is linked to the input (8) of the second pacemaker (7) which, after a slight delay generates impulses (9) to the ventricle via a probe (10). An atrium probe (1) is switched by remote control (13) either to the first (3) or the second pacemaker (7).
