Title: Moving dolls eye with sideways pivoting pupil - has carrier in pivot body which pivots vertically inside eye housing
Inventor: ENGELHARDT SIEGFRIED
IPC: A63H3/40
Filed: 1976-02-26
Abstract: This movable dolls eye contains an eye which can move sideways as well as open and close. It consists of a housing (1) which holds the movable eye made up a pupil carrier (3) and a pivot body (4). The pupil carrier (3) pivots from side to side on vertical pegs (5, 6) inside the pivot body (4) while the pivot body pivots up and down on horizontal pegs (9) inside the eye housing (1). Fixed to the lower part of the pupils carrier (3) close to the lower pivot (6) is an eccentric weight (13) which ensures that the eye moves as the doll is laid on its back or its side. The pupil carrier (6) comprise an natural looking iris, which is partly covered by eye lashes (18) fitted to the eye lid covering above the iris. This provides a dolls eye which moves in a natural manner.
Patent DE-2616655-A1 (DE)
Inventor: GYURECH GABOR
IPC: C01B7/01
Filed: 1976-04-15
Abstract: The liquefier in tubular-boiler construction has the heat-exchange tubes (1) which serve for liquefaction and which are cooled from outside by a cooling liquid (A), and moreover at least one downpipe (2) and at least one liquid overflow (3) as well as gas inlet openings (4) to the individual heat-exchange tubes. In operation, the liquefier is filled to slightly above the upper tube bottom (5) with condensate, while the gas to be liquefied is blown in through the inlet openings (4) under the heat-exchange tubes (1). A lift arises, which conveys the condensate/gas mixture through the tubes at such a great speed that a great turbulence and a correspondingly good heat exchange are created at the tube wall. The liquefier is suitable inter alia for obtaining liquid chlorine from a mixture of chlorine gas and hydrogen gas without the risk of explosion. <IMAGE>

Title: Mast chimney or column climbing device drive - has knife edged wedge protrusions across drive rollers or continuous tracks
Inventor: SPRENGER PETER
IPC: E04G1/20
Filed: 1976-04-23
Abstract: The drive assembly is for a device for climbing up or down masts, tree trunks, chimneys or columns, for repair work, bark and branch stripping, or other purposes. It incorporates at least one drive roller (1), or continuous track, with a series of vertically extending wedge-shaped projections (3) on its running surface. These bear knife edges (4) aligned across the line of the mast. The spacing between these can be such that the stem remaining between two successive projections engaging the mast suffices to bear the climbing device and personnel. There may be a number of such rollers or tracks following each other. Ascent and descent can be safely negotiated even under heavy or uneven loading.

Title: Membrane pump with sectionalised pump body - has two membranes with reciprocation transmitted by fluid via controlling valves
Inventor: RING SANDIFORD
IPC: F04B43/00
Filed: 1976-05-28
Abstract: The membrane pump body has three sections with a first chamber between the first section and one end of the second section and with a second chamber between the other end of the second section and the third section.

This device is bound by the second section and the two membranes. A further device effects a reciprocation of the first membrae and the third section has an inlet and an outlet connected with part of the second chamber bounded by the third section and the second membrane. Valve equipment in the inlet and outlet allow the flow of a process medium only through inlet and outlet. The parts of the first and second chamber and the fluid connection equipment form a power transmission fluid path.

Title: Zone melting large dia. silicon bar - using periodic rotation of bar to prevent short circuits between bar and induction melting coil
Inventor: KELLER WOLFGANG DR RER NAT
IPC: C30B13/32
Filed: 1976-06-15
Abstract: A vertical semiconductor bar, esp. monocrystalline silicon, held at both ends, is zone melted without using a crucible, but using a ring-shaped inductive heating coil. The top holder for the bar is not rotated continuously, but is rotated round its axis during specific periods of time. The discontinuous rotation is pref. achieved by feeding pulses to the motor rotating the holder, esp. using phase control for acceleration from zero speed to max. speed, followed by redn. to zero speed; after a brief pause the cycle is repeated. The max. speed of the holder is pref. 20 R.p.m; the pulse duration is pref. 1 second; and pref. 20 periods or rotation are used per minute. The pulses duration and height may be varied during the process. Method prevents hairs of Si forming at the periphery of the molten zone; such hairs can cause short circuits between the bar and the induction coil, thus stopping the process.

Title: Manual drive for wheelchair - has clamping block on pivoted lever acting on wheel or drive ring
Inventor: BACKFISCH KURT
IPC: A61G5/02
Filed: 1976-09-21
Abstract: Manually actuated drive mechanism for wheelchair comprises a ratchet-like clamping block (8) which is mounted on a guide arm (4) in such a way as to be radially movable by means of a two armed tilt lever (6) attached to the guide arm. The guide arm is pref. guided by means of a roller carriage with slide member, of which the rollers engage the drive ring or the wheel of the chair from one side, while the slide member engages the drive ring or wheel the other side. At the front end of the tilt lever is pref a widened zone (20) extending transversely to the longitudinal axis of the tilt lever. The arrangement requires less effort to advance the wheelchair and avoids the risk of soiling the sleeve of the user.

Title: IR radiation food grill - has inner and outer radiators for cooking and browning with inner radiator enclosed in radiation permeable tubes
Inventor: FRITZ KARL DR
IPC: A47J37/04
Filed: 1977-06-24
Abstract: The grill, for food e.G. poultry, uses infra-red radiation to 'brown' the food externally and to cook it internally internal heating is accomplished by an internal IR radiator enclosed in a metal spacer and/or enclosed in several radiation-permeable tubes to increase thermal conduction and heat transfer. A coolant may flow in one of these tubes. The internal radiator also functions at a rotatable spit. The outer side of the outer spacer tube may have grooves or ridges along its length which prevent rotation of the food on the external conductor.

Title: Appts. for severing weld beads from welding seams on plastics profiles - has cutter mount and plate integrated into welding machine table by cooperating with table movement
Inventor: KEMPER KARL
IPC: B29C37/04
Filed: 1977-07-23
Abstract: Device for cutting-off the weld bead on plastics welding seams, esp. welding seams of window profiles, has 2 cutter plates whose cutting edges bear upon the surface of the profile and whose cutting line lies above the welded gap. the cutter plates are adapted to opening and closing motions, via lever arrangements. Novelty is that the cutter mount and cutter plate follow the movement of the machine table; the welded article being first pressed together, the cutter spar then being advanced, and the weld bead being finally severed. The device, as claimed, is integrated into the working table of the welding machine, thus facilitating trouble free operation and enabling operation to be controlled by the function of the welding machine. This is achieved by cooperation of cutter mount and plates with the movement of the machine table, followed by severing step.
