Title: Ventilation system for bathrooms and toilets
IPC: F24F11/00
Filed: 1981-11-16
Abstract: A system for the central ventilation of rooms of a building, preferably of bathrooms and toilets, by means of an air conveying device 12, 13, the rotational speed of which can be adjusted in stages and which is connected via a duct system to air outlets of the relevant rooms for the extraction of used air, which air outlets comprise adjustable air-core choke devices (20) which are normally in predetermined first positions for strong throttling of the used air in order to maintain basic volumetric flows of the used air and can be switched to second positions for increased ventilation. In order to ventilate the rooms as required, a store (25) is associated with the air-core choke devices (20), the content of which store is in each case increased by one stage as a result of the individual air- core choke device being switched into the second position and in each case lowered by one stage as a result of the individual air-core choke device being switched into the first position, the air conveying device being switched over into its different rotational speed stages as a predetermined function of the content of the store.   <IMAGE>

Title: Bi-chamber rotary elastic-fluid engine
IPC: F01C1/352
Filed: 1981-11-24
Abstract: A valveless turbine-like rotary engine employs two sets of rotor or sealing blades 35, 36, 37; 38, 39, 40, rotating around separate eccentric points on a stationary mutual crankshaft 42 within a drum-type rotor 9 concentrically mounted within an oblong engine chamber 1, 2. The drum-type rotor 9 forms the oblong chamber into two diametrically opposed radial chambers through each of which one set of the rotor or sealing blades pass as the drum 9 rotates. The two sets of blades move radially through equidistant slots arranged within the drum-type rotor 9 so as to be extended into one of the radial chambers, thus varying the effective volume of the respective radial chambers through which they move. Accordingly. the introduction of a pressurized medium through diametrically arranged inlet ports 5, 6 into the radial chambers rotates the blades and the drum. <IMAGE>

Title: Helical spring for spring cores of mattresses and furniture
Inventor: THOENEN ALAN
IPC: A47C27/06
Filed: 1982-08-19
Abstract: A helical spring (1) for the spring core of a mattress or other furniture is described and is made of spring wire. The spring has two knotted end coils (2a, 2b) lying in approximately parallel planes. Each end coil contains a single convexity or bulged zone (5a, 5b) in which the spring wire (6a, 6b) runs substantially in a straight line. The region of each end coil lying opposite this convexity follows a circular path (7a, 7b). The two convexities (5a, 5b) of each end coil preferably lie diametrically opposite each other. A spring core manufactured from such helical springs has the same utilization qualities as so-called "Offset spring cores", in which in each end coil two convexities are present. However, it is much easier and cheaper to manufacture on automatic assembly machines than the "Offset spring cores". <IMAGE>

Title: A display repeater
Inventor: DARNELL MICHAEL
IPC: G06F3/147
Filed: 1983-08-13
Abstract: The repeater comprises an array of light sensors 21 and may overlie a light-emitting display 20 so that each element of the display is read by a respective sensor.

Title: Commutated capacitor circuit
Inventor: HAIGH DAVID GEORGE
IPC: H03H19/00
Filed: 1983-08-25
Abstract: A switched capacitor parasitic insensitive integrator comprises an operational amplifier (6) an integrating capacitor C2, a switched capacitor C1 and four switches, two of even phase E1, E2 and two of odd phase 01, 02. In order to minimise the effect of capacitances (42) associated with the switches a switching waveform is used such that E2 opens before E1, 02 opens before 01, E1 is not closed when 01 is closed and E2 is not closed when 02 is closed. A clock circuit may be used to provide a 4-phase switching waveform with a separate phase signal to each switch or a 2-phase switching waveform may be used with one phase signal to the E switches and the other phase signal to the 0 switches and the two switches E2, 02 biassed relative to E1, 01 such that the required differences in switching times occur. Either input 21 or 22 may be connected to a reference source, and an input signal applied to the other. <IMAGE>
Patent GB-2145910-A (GB)
Title: Data display arrangement with scrolling
Inventor: BUGG RICHARD EDWARD FREDERICK
IPC: G09G5/34
Filed: 1983-09-01
Abstract: In a data display arrangement, in which rows of characters identified by digital codes stored in display memory (9) are displayed on a raster CRT (10), the data in the memory is recurrently addressed for display in successive fields. The codes are converted to characters by loop-up memory (11). Vertical scrolling is achieved by delaying in (22) the transmission of starting pulse (SP) to the dot row counter (14) so that addressing of memory (9) is delayed relative to the field scan by a number of lines or character rows, this number being held in register (23) and incremented periodically by logic (21). A mapping RAM (24) enables character rows to be rearranged vertically, e.g. for centering. The invention may be applied to data stored in a bit-map, without the row mapping facility, the delay being an incrementing number of lines. <IMAGE>
Patent GB-2145805-A (GB)
Title: Plate freezer
Inventor: FENNER FRANK RICHARD
IPC: F25D31/00
Filed: 1983-09-02
Abstract: A plate freezer has a stack of plates 1,2,22 and raising and lowering means to position plates in the stack sequentially at a loading and unloading station 3, raising the stack bringing a plate to be loaded and unloaded to a level above the station 3 and the plate above it to a position to engage latch means, lowering of the stack lowering the plate to be loaded to the station 3 and engaging the plate above it with the latch means. Because product may adhere to both adjacent plates and because adjacent plates when one is engaged by the latch means and one is at the station 3 are spaced by more than twice the height of frozen product so that a pusher stroke to break adhesion may not affect product adhered to the plate engaging the latch means, a control is provided to interrupt lowering a plate 2 to the station 3, and an auxilliary guide latch 20 is provided to yield when the pusher 4 is on a normal return stroke and riding on a guide latch 9, but on an adhesion breaking stroke and return the auxiliary latch 20 will guide the pusher 4 at the level of the plate 2 when its descent is interrupted, so that adhesion of product adhered to both plates 1,2 will be broken. <IMAGE>
