Title: Space heater connector plate - has water heated in radiator while travelling in parallel cellular conduits formed between surface of corrugated heater plate
Inventor: LUX FRANZ
IPC: F28F3/02
Filed: 1989-05-24
Abstract: The space heater convector plate has water heated in a radiator while travelling in parallel cellular conduits (33) formed between the surface of a corrugated heater plate (3) and the contacting matching surfaces of cellular flues (21) for rising hot gas. Between pairs of aparallel cuts in the flue corrugations, surfaces (12,12a) are bent outwards to face away from the water conduits and provide access for air which can exchange heat with media in adjacent cavities, esp. by the cut-sections combining to form further flues in contact  with the water conducts. Two similarly profiled heater paltes may be positioned back to back, with the bent out surfaces of one palte engaging the corresp. offset gaps of the second plates, a d to plates welded or adhesively bonded together. USE/ADVANTAGE - Esp. for space-heaters.   Easily-formed units yield high heat output from relatively thin assembly.

Title: Sewing machine fabric edge monitor - uses single light measurement channel from light box for integral regulator
Inventor: HAUCK WOLFGANG
IPC: D05B69/24
Filed: 1989-09-23
Abstract: Monitor system to register the position of a fabric edge, e.g.  for a sewing machine, generates a signal according to the position within a light box. The compensation unit is an integral regulator (20) which monitors the deviation of the measurement signal (Ux) from a fixed reference value (Ur) and passes a setting signal (Uy) to the monitor (10) to correct the monitored deviation. A warning unit (40) monitors the setting signal of the control (20) while a fabric workpiece (11) is absent at the monitoring station, and generates a warning signal if the setting signal  (Uy) exceeds a preset threshold value. The circuitry has a comparator (30) which calculates the difference between the measured signal value (Ux) and a threshold value (Us') to give a fabric edge identification signal (Sk) on changing the plus/minus sign of the difference. ADVANTAGE - The system uses a single light measurement channel to register the position of the fabric edge and detect any misalignment.

Patent DE-4013840-A1 (DE)
Inventor: BECKER JOHANNES DIPL ING
IPC: H01H21/40
Filed: 1990-04-30
Abstract: The aim exists to reduce the size of low-tension switchgears, but on the other hand it is intended to improve the switching power. New requirements now demand that the contacts of the low-tension switchgears close more quickly in order to achieve a small amount of contact erosion and hence a longer life of the low-tension switchgears. The invention indicates a means by which a switching mechanism is produced with only a few individual parts, a bell crank system 2, 3, 4 drives a contact shaft 6 via a switching lever 1, a locking device 9, 10, 11 initially locks the contacts 7, 8 shortly before touching, and, in the case of further operation of the switching lever 1, switches on suddenly, and a trip device 14, 16, 18 opens the contacts 7, 8 in the case of a fault current. Such a switching mechanism can be used in low-tension switchgears, preferably in fault-current protection switches. <IMAGE>

Inventor: GOERLICH UWE
IPC: F25D3/11
Filed: 1990-05-31
Abstract: In devices for freezing pourable and flowing materials by direct contact with a low-boiling liquefied gas, the materials are moved on a conveyor belt many times through a bath consisting of the liquefied gas. These devices are well-suited for continuous production on an industrial scale, but have a high space requirement. For scientific use, for example, small easily sterilisable devices are preferred. Such a device consists of an insulated housing (1), in which a rotatable hollow cylinder (2) is arranged, the axis of rotation (3) of which is inclined at an angle to the horizontal and on the inner wall of which a band worm (5) is arranged. In the hollow cylinder, the bath (7) consisting of a low-boiling liquefied gas, for example nitrogen, is situated. Arranged above the deepest point of the bath is the introduction device (9) for the material to be frozen (Fig. 1).

Inventor: KOSIKOWSKI THOMAS DIPL ING
IPC: C25D21/04
Filed: 1990-07-27
Abstract: The invention is based on an apparatus for the electroplating of work pieces in baths which are open at the top, which have lids for optionally covering said tops, an extraction system (12) for the vapours in the bath containers above the liquid level (9) of the bath liquid and a conveyor carriage for introducing the work pieces, which are held by product carriers (2), into the baths or removing them from the baths. Furthermore, a system of air inlet openings or intake openings at a suitable distance below the upper rim of the bath container ensures that turbulence of the air sucked in is substantially avoided and a substantial part of the liquid vapours in the space (10) of the liquid level is picked up by this air stream. To simplify such an apparatus both in its construction and in its handling or operation, provision is made for each of the lids (1) to be detachably held on a product carrier (2), the respective product carrier being capable of being moved away downwards (5) from the associated lid.
