Title: Stacking moulded plastics filing tray - has ring underneath to locate in recesses in tray below, to swing about vertical axis
IPC: B42F7/12
Filed: 1976-01-23
Abstract: A moulded plastics filing tray is of conventional shape with three sides and a partly open front with a sloping guide lip (3) across it. On the underside is moulded a ring (6) having an outside diameter which is slightly smaller than the width of the tray. This locates between the sides of another tray underneath, when stacked, to retain it securely in position. To assist location, each tray has a set of three curved cut-outs (7a, 7b) into which the ring (6) on the tray above fits. This enables the upper tray to swing round about a vertical axis. The three cut-outs fire three alternative positions so that trays can overlap when stacked. Two grooves (9a, 9b) through can be used to locate the top edge of the tray below to retain it.

Title: Central heating boiler control - has switching on level of boiler thermostat dependent upon outside temp. thermostat
IPC: F24H9/20
Filed: 1976-04-05
Abstract: In an embodiment the boiler (1) of the central heating system is connected to the radiators by means of forward and return pipes (2, 3). The burner (4) is switched by the boiler thermostat (5). The switching on level of this thermostat (5) is dependent upon the outside temp. measuring thermostat (6). A minimum lower temp. is however, maintained at all times. An additional control (8) can be switched in the control circuit via switch (7) to make the temp. level dependent upon the time of day. The burner is then only switched on when the additional control contacts are closed. This addition allows the temp. to drop during the night.

Title: Motor operated swinging door release catch - has handle for quick release at hinge pin in event of power supply failure
IPC: E05F15/16
Filed: 1976-04-23
Abstract: A swinging door (2) has its frame secured by a latch (17) to an arm (12) with a pivot pin (8) which passes through a slot (7) in a bracket (6) which is moved away from the door to open it. This bracket is part of a carriage mounted on a chain driven by a motor so that the door can be opened and closed automatically. In the event of power failure, a handle (19) attached to the door is rotated so that a pin (18) is swung through an arc which lowers the rod (17) forming the latch releasing it from the strap (16) holding the hinge pin (13) thus separating the door from the carriage. The door can then be opened by hand. The other end (9) of the arm (12) can be swung down to release it from a stop (11) on the top frame (4).

Title: Cardboard support for displaying goods for sale - has self-adhesive sheet folded to form tag with hole for hook(OE150776)
IPC: B65D25/22
Filed: 1976-04-27
Abstract: The support is intended for use in self-service shops where 'gift wrapped' articles are displayed. The support consists of a strip of cardboard with a self-adhesive surface on one side. The strip is divided into three parts (2, 3, 4) by the fold lines (5, 6). Two slots (9) are arranged symmetrically on either side of the fold line (5) so that when the strip is foled the slots (9) coincide. The flap (2) is then stuck to the surface (3) and the tag thus formed is stuck to the article on display by the flap (4). The supports are mounted on long backing strips when manufactured so that they can be easily stored and peeled off when required.

Title: Movement of recording pen and carriage - uses air pressure to move membrane for recording and lifting carriage
IPC: G01D15/24
Filed: 1976-04-12
Abstract: A manometric membrane is used in the carriage for a recording brush of adjustable length. Air pressure pulses move the membrane for recording purposes and also provide a cushion of air to lift the carriage. The membrane (7) is attached to a part (8) into which a threaded shaft (9) holding an inscribing brush (10) is screwed. The shaft permits adjustment of brush height above a table (1). Small diameer holes (11) in the membrane allow little air under pressure into a cavity (12) providing a cushion of air (13) between the carriage and table. Air is supplied in pulses from a pump via a tube (4) to the membrane enclosed cavity.

Title: Stabilising compsn. for trichloroethylene and tetrachloroethylene - contg. a nitroalkane, a pyrrole cpd. and a phenol
IPC: C23G5/028
Filed: 1976-07-06
Abstract: Trichloroethylene and tetrachloroethylene are stabilised by adding a stabiliser mixt. contg. nitroalkane, >=1 pyrrole cpd. and >=1 phenol cpd. Previous stabilisers e.g. phenols and N-alkyl-pyrroles are not sufficiently effective and they do not present rapid decomposition when the solvents are used in degreasing metals. Present mixt. of stabilisers gives a synergistic stabilising effect so that the composition is effective even in small doses. Decompsn. of the chloro cpds. forms HCl.

Title: Centrifugal removal of oil from nuts or screws - by spinning them inside a perforated drum with an open base for emptying
Inventor: SORTAIS ANDRE
IPC: B04B5/00
Filed: 1976-10-28
Abstract: Appts. for cleaning small parts such as screws or nuts by centrifugal action to remove traces of oil or other impurities with which they are contaminated during mfr. is claimed. The parts to be cleaned are fed into a drum turning at high speed so that they are forced outward and cleaned by the effect of the centrifugal force. The drum is open at the bottom, the parts to be cleaned being received in an inner receptacle when they are fed into the appts. Hence, when the drum stops turning, the pieces which have been spun against the walls fall under gravity and may be removed. Appts. is relatively cheap both to produce and maintain. It is comparatively small. By ensuring an even dispersion of the parts, efficient cleaning is facilitated. The feed-in of the parts and their removal after treatment is simple.

Title: Electrical transfer function regulator - uses operational amplifier and resistance bridge associated with given transfer element
IPC: G06G7/26
Filed: 1977-01-19
Abstract: The transfer function regulator has an operational amplifier and a variable resistance bridge associated with a given transfer element. The regulator permits a variation of the global transfer function included between the transfer function of the element and the inverse value of this function at the moment of variation of the value of at least two resistances. The variable global value of the transfer function is defined by the relationship X(p)=(F(p)-k)/(1-kF(p)) where F (p) is the given transfer element, k is the relation connecting the variable resistances. This relation is R1/R3-R4/R3=k, k varying from O towards positive infinity. The simultaneous variation of at least two values of resistance causes the variation of the resistance ratios.

Title: Solar radiation heat exchanger - consists of low cost panel with water in circulation channels covered to reduce ratio of emitted to incident radiation
IPC: F24S10/50
Filed: 1977-06-14
Abstract: A solar heat exchanger consists of a panel, one surface of which receives solar energy. That surface has parallel V shaped grooves which extend over the length of the panel. Three sheets of plastic are laid over one another on the surface and form outer, intermediate and inner spaces, extending over the length of the grooves, and bounded by the walls of the grooves and the sections of the sheets extending over them. The outer and intermediate spaces contain air. The inner spaces, of triangular section, constitute channels through which water circulates, and which connect with gutters at the ends of the panel. Pipes connected to the gutters feed water and take it away. The water receives radiations after they have passed through the sections of sheets and the outer and intermediate spaces. The collector is simple to construct and can be readily dispatched, stored and installed at low cost, whereas the costs of existing collectors prohibit their wide use. It collects incident light of all wavelengths and emits only a small quantity of radiation. The temp. can be controlled preventing damage if fluid circulation is interrupted. Conversion of incident energy is considerably greater than with existing panels.
