Title: Thyristor control circuit for gas discharge lamp - regulates trigger pulses according to requirements and prevents surge on current interruption
Inventor: WATERMANN GREGOR
IPC: H05B41/392
Filed: 1975-03-11
Abstract: A circuit is used for the operation of high pressure vapour lamps using an ultra-violet layer applied by the drying of a lacquer layer. It uses a thyristor to regulate operation in accordance with power requirements so that the discharge is not quenched during no-voltage phases and it prevents excessive current surges after temporary interruption of the supply. An ohmic bridge resistance (5) is applied across the thyristor regulator unit (2) to maintain the discharge of the lamp (4) at minimum discharge and the thyristor adjustment alternating current is maintained at a constant operating value by means of a regulator (6) by alteration of the phase of the triggering pulses. On failure of the feed voltage the trigger pulses are fed at a phase with a minimum difference from the zero voltage point of the alternating voltage.

Title: Refrigerator door catch and handles - has push rod for lock catch operated from within refrigerator
Inventor: GABLER MARTIN
IPC: E05B65/00
Filed: 1975-04-28
Abstract: The lock of doors of refrigerated and deep freeze rooms has a spring-loaded, handle-actuated, moving bolt lock. The lock engages a rotating latch in the door frame. The door has actuating handles which are accessible from the inside and outside of the refrigerated room. The lock mechanism is readily built within the door and the door is opened readily from inside by exerting pressure on the handle (22) for example by a person carrying a load who has no hands free. The connector between the inside actuating handle and the lock catch is a push rod (21) which actuates a pivoted lever (20) which exters pressures on the lock catch (9) pivoted about a pin (10). The push rod passes through the door and is operated by its inside handle (22). The pivoted lever is held within the outside actuating handle (8).

Title: Lace distribution mechanism in lace weaving machine - has rotary ring fitted with two parallel arms working in guides which distribute laces round weaving frame
Inventor: FABBIAN FRANCESCO
IPC: B27J1/00
Filed: 1975-05-14
Abstract: The lace distribution mechanism is particularly used for tensioning weaving seat frames in machines and it has a rotary ring which is equipped with means for delivering the laces. The ring is fitted with two parallel arms which work in guides. The first of the guides acts as a return guide for the two laces which are delivered via two rollers. The second of the two guides is ued to move the laces intermittently and concentrically round the weaving frame. Thus over >=180 degrees of rotation, corresponding to one side of the frame there is no concentration of the two laces.

Patent DE-2612944-A1 (DE)
Title: Shutterless cine camera and projector - use rotating disc mirror with surface shaped so that reflected image has constant place w.r.t. frames on moving film
Inventor: MINDERMANN FERDINAND
IPC: G03B41/06
Filed: 1976-03-26
Abstract: The light coming through the lens is projected on to the film by a rotating disc mirror, whose surface is so shaped that the reflected image keeps the same plate w.r.t. frames on the moving strip of film. Along one radius of the disc there is a step (elsewhere the gradient changes continuously). When the light from the lens crosses this step, a new, separate image is formed on the film. The disc rotation is synchronised with the film movement (which may be very fast), but neither a shutter nor a sprocket drive is required. Only a sector of the disc need be used (the pictures are then separated by time intervals). Conversely, the whole gradient can be contained in a sector, and several such sectors contained within the circle (then several film frames correspond to a single rotation of the disc).

Title: Metals magnetic pulse working inductor - with conductive insulated segment shaped inserts in annular concentrator grooves to extend working life
Inventor: CHIMENKO LEV TIMOFEJEVITSCH
IPC: H01F7/20
Filed: 1976-03-26
Abstract: An inductor for magnetic pulse working of metals comprises an annular magnetic field concentrator with an opening to receive a workpiece and annular grooves in its outer surface containing a winding. The grooves define ribs in which segment-shaped grooves of rectangular cross-section are formed with a maximum depth equal to that of the annular grooves. A radial slot links the annular grooves with the opening. The segment-shaped grooves perpendicularly to the slot plane and receive electrically conductive segment-shaped inserts insulated from the concentrator and overlapping the slot. The inserts may be separated by polyfluoroethylene or polyethyleneterephthalate gaskets from the concentrator. The arrangement eliminates the effects of radial and axial electrodynamic forces on the winding, thus extending working life.

Title: Double glazing with reversible heat flow compensation - has partitions between panes to localise heat or move it by convection
Inventor: STANGE JOACHIM DIPL PHYS DR RE
IPC: E06B3/67
Filed: 1976-10-18
Abstract: The double glazed window checks loss of heat from indoors in winter, while permitting max. inflow of midday heat from outside and in summer reduces heat inflow from outside dueing the day and permits escape of heat at night. There are partitions rising between the double panes, to ensure that warm air remains on the warm side and cold air on the cold side when required. When required, warm air is convectively carried to the cold side, and vice-versa. Transformation from to winter to summer compensating action can be effected by using turning windows or by adjustable partitions. The partitions are made of glass or transparent plastic, with low heat conductivity, and may be thin or double-walled.
