Title: Electric radiator with increased surface area and min. thermal losses - has two plates enclosing space on wall side with plastics spacers providing insulation
Inventor: REDEL DIETER GEORG
IPC: F24H3/00
Filed: 1979-02-09
Abstract: An electrical radiator has ribs on both sides to increase the surface area of the heating element. The thermal losses are kept to a min. The ribs of the radiator facing the room are eigher welded or rivetted on. They are loosely inserted in a sheet with holes, which surrounds the heating core. The side of the radiator facing the wall consists essentially of two closed plates enclosing an air gap which functions as a thermal insulator. The spacer between the two plates is made from a plastics material. The heat transfer is therefore direct into the room where it is reqd.

Title: Tuning aid for FM radio receiver - disables tuning when two specified stored voltages have different polarities
Inventor: BOCK MANFRED
IPC: H03G3/34
Filed: 1979-05-22
Abstract: The tuning aid temporarily stores the voltage derived from the directional voltages resulting from the output of the frequency demodulator during transmitter selection and tuning. When two stored voltages have different polarities, automatic tuning and/or interference pulse blanking circuits in the receiver are disabled. An acoustic signal is actuated that switches off when the receiver has been tuned precisely to the wanted transmitter. The acoustic signal aids tuning. The tuning aid contains two threshold switches, two timing circuits, and a third switch.

This enables the usual horizontal pipes to be also used in a vertical position, with less earthworking involved.
Patent DE-2931574-A1 (DE)
Title: Continuous fabric heat treatment - uses fabric zones to give correction valve for consistent controlled temp.
Inventor: GUILLOT FRANZ E
IPC: F26B25/22
Filed: 1979-08-03
Abstract: In controlling the temperature of the continuous material, such as carpeting or felt, the various zones are brought to a reference value through a control circuit which takes the maximum deviation in a zone between the actual and reference values as the correction value for all the zones in the material. The temperature reference value of the zone with the greatest deviation is taken as the correction factor. The process allows wide fabrics to be given a temp. treatment by using a common or a number of identical temp. references values so that a group of separate zones can be subjected to the same temp. in a given time.
Patent DE-2931928-A1 (DE)
Inventor: MEISSER CLAUDIO
IPC: G01K17/16
Filed: 1979-08-07
Abstract: The specific enthalpy (h) is stored in a first read-only memory (4) of the heat meter, and the density (p) of the heat carrier is stored in a second read-only memory (12) as a function of the temperature (T) of said carrier. A computer (3, 5, 10, 13, 17, 20) determines the thermal energy (Q) from the volume flow rate (@), the density (p) and the difference ( DELTA h) between the specific enthalpy (hTv) in the feed and the specific enthalpy (hTr) in the return. A third read-only memory (11) contains a correction quantity (K) for the measuring signal (SV) of a volumetric flowmeter, and a fourth read-only memory (2) contains correction quantities for the measuring signals (STv:STr) of a feed temperature sensor and of a return temperature sensor. An alarm signal transmitter (25) generates an alarm when the temperature sensors or other state sensors (26) detect irregular states or changes. A further read-only memory (22) contains a tariff quantity (A) as a function of a temperature difference ( DELTA T), and the computer (3, 5, 10, 13, 17, 20, 23, 24) forms the time integral (Qv) of the product of the heat output (P) and the tariff quantity (A). <IMAGE>

Title: Bearing cap for small machine ball race - giving firm location without requiring close dimensional tolerances for bearing housing
Inventor: LATUSSEK HANS-PETER
IPC: F16C25/08
Filed: 1979-09-29
Abstract: The fixed cage ball race (3) is a press fit on the motor shaft (6), and is contained in a bearing housing (41) in the machine endplate (4). The bearing cap (2) for locating the ball race has an axial extension with a wedge shaped cross section (21). There is flexibility between the bearing cap flange and the axial extension (21), typically a bellows section (22), to apply axial pressure to the outer race (31) when the cap is bolted (5) to the endplate. The angled face (211) of the extension is radially inwards, and bears against the outer face(31) to push the bearing against the bottom (44) of the bearing housing, and also compensate for any gap (b) between the outer race and the bearing housing bore. The bearing clamping arrangement removes the need for close dimensional tolerance of the stationary parts. The bearing cap in particular can thus be made as a plastic moulding.

IPC: F27D1/18
Filed: 1979-10-06
Abstract: The furnace consists of a U-shaped trough resting on rollers which are driven by a motor to tilt the trough in alternate directions, one for charging, and the other for cleaning the furnace. The trough is closed by a lid fitted with wheels mounted on rails; and each side of the lid has a flange pointing downwards and ending in a recess forming a pivot bearing for a shaft fixed to the trough. The underside of the lid is pref. fitted with a skirt entering a recess on the top edge of the trough to form a seal; and the trough pref. rests on friction rollers employed for tilting. The sealable lid increases the thermal efficiency of the furnace so fuel consumption is reduced.

Title: Laminated magnetic core stampings for transformers and chokes - form shell from similar yokes with outer and centre limbs and variable air gap
Inventor: ULRICH PETER DIPL ING
IPC: H01F41/02
Filed: 1979-11-09
Abstract: A laminated magnetic core is formed from stampings with the min. of waste. They are used in the construction of transformers and chokes. The air gap can be adjusted by the method of assembly. The ratio between the sides of the sections and the ratio between the width of the window and the height can be selected independently of the limb or the width of the yoke. The shell is formed from two similar yokes with perpendicular outer limbs (1) and a centre limb (2). The centre limb forms a variable air gap (3) with the two yokes. The adjustment is made by shifting the two yokes in parallel.

Title: Fluorescent tube and high pressure vapour lamp operating system - initially connects lamps on starting to AC mains, with subsequent switching to light control mains
Inventor: LUECK HARALD
IPC: H05B41/392
Filed: 1980-01-08
Abstract: The system is intended for luminous flux control, of fluorescent tubes, high pressure vapour discharge lamps etc., using a luminous flux control in dependence of ambient light, detected by photosensors. On starting the lamps, they are first connected to a normal supply a.c. mains (NN) at a mains voltage corresponding to the full lamp operating voltage. Then with a time delay they are switched to the regulated mains of the light control device. The switching can be manual, or automatic. The starting switching may be carried out by a single-pole change-over switch, which may be also used for the delayed switching to the light control device. This switch may be fitted with a time element (22) for automatic change-over after a certain time period. The time element may be connectable to the a.c. mains via a lamp switch, and may actuate a change-over member. The rest state of the latter enables connection to the mains, while its operational state provides connection to the controlled supply.

Abstract: The seat can be set in height and/or inclination or longitudinal position. A control device controls the motor that sets the position of the seat. An end-switch detects when the seat touches an obstacle in its path. The end-switch is a two-pole direction-reversing switch that reverses the direction of rotation of the motor so that the seat direction also reverses. The contact of the end-switch (111) are connected in a specified manner to the contacts of a changeover switch (110) that is operated manually to reverse the direction of the d.c. motor (107). The motor is supplied from the vehicle battery via the two switches.
