Title: Hot water system for domestic use - has heat pump between waste water reservoir and incoming fresh water
IPC: F24D17/02
Filed: 1975-05-30
Abstract: A house (1) has a kitchen (10) containing appliances such as a washing machine (11) a dishwasher (12) and a sink (13). A bath (16) and a basin (18) in a bathroom (15) also discharge waste water into the same waste pipe (20). This is taken into a reservoir (21) the discharge (28) from which is at a higher level than the inlet so that the waste water is forced to accumulate in the reservoir. It discharges from the reservoir to the town drains (29). Fresh water from the mains (22) flows into a tank (23). This is connected to the waste water reservoir by a heat pump (25) with the evaporator in the reservoir and the condenser in the tank.

Title: Automatic stopping of telephone call signal - is provided by photo:thyristor controlled from detector output
Inventor: LE LUONG
IPC: H04M3/00
Filed: 1975-09-26
Abstract: Tone ringing used with electronic telephone exchange equipment uses low energy signals at high frequency which is not detected in equipment using electromechanical bells. This problem and that of automatically stepping call signals is overcome in a central control unit with a latching circuit. A telephone (1) is connected via lines (a,b) to a balanced translator (T1) with balanced secondary windings on which call frequency appears. A battery (B) supply is connected via coils (L1,L2) providing high impedances for phonic frequencies. A photocoupler (TPH1) detects changes of telephone circuit state and a second photocoupler (TPH2) senses call signals from the call generator output (S1,S2). A photothyristor (THY) controlled (DTHY) from a detector (WS) provides automatic stopping of the call generator output.

Title: Multi needle perforating and embroidering machine - with traversing carriage which allows supply reel to move continually during needle cycle
IPC: D05C9/06
Filed: 1975-10-02
Abstract: A machine for perforating and/or embroidering one or more bands of fabric, has a frame and a needle bar arrangement fixed relatively to the frame, and reciprocating constantly up and down. A carriage is assembled on the frame, and reciprocates transversely relatively to it and to the needle bar, whilst supporting a draw roller for feeding the fabric to be patterned, lengthways toward a take-up roller, as well as a motor and a tension roller assembly. A supply reel rotates in bearings on two arms, hinged on the carriage so as to be able to move independently of the carriage and in the same direction. On the shafts to which the arms are attached, calibrated damping springs are fitted between the arm and the bearings in the carriage structure, to check the motion in each direction. Appts. considerably reduces the inertia of the mechanism so that the drive can be arranged without the use of expensive motors, and lightweight fabrics can be handled correctly. The supply reel or reels move during the whole of the needle cycle of 100 ms; the duration of the dwell of the fabric being patterned remaining unchanged.

Title: Optical displacement sensor for optical transducer - has displacement sensitive strip to compensate for displacement of emitter or receiver
IPC: G01B11/02
Filed: 1976-03-22
Abstract: A sensor is used to measure the displacement of either the emitter or the receiver of an optical transducer. It can provide a signal to compensate for any effect of the displacement on the quality of the transducer. The sensor comprises the optical emitter (a) and the optical receiver (b) of the transducer. The emitter (a) can be light emitting diode and the receiver can be a photo-diode or a photo-transistor giving a signal proportional to light intensity. A strip of material (c) is placed between the emitter (a) and the receiver (b). The strip has an optical transmission coefficient which varies linearly in the direction of displacement of either the emitter (a) or receiver (b). The signal due to the displacement is fed to any subsequent electronic unit used with the emitter or receiver (a, b) and can compensate for the effects of the displacement.

Title: High-strength formed coke - produced by briquetting low-quality fines of specified reflectance/agglomeration property index
IPC: C10L5/04
Filed: 1976-04-01
Abstract: High-strength, slightly agglomerated formed coke is produced in a horizontal-chamber coke oven battery charged with fine low-quality coal particles which have been screened to is not >1.5 mm size. The mixt. of fines has an agglomeration property (AP) index of >=75, a max. average reflectance of >=1.2% and an expansion/contraction ratio of -2% to +5% during a coking process at a heating rate of 5 degrees C/min. The fines are mixed with an agglutinant and pressed to briquettes of dumb-bell shape before they are charged into the coke oven battery. This produces a formed coke of satisfactory quality for blast furnaces. No difficulties arise during the pushing of the coke cake because the outer parts near the heating walls are not too firmly agglomerated nor are the inner parts left loose. Its permeability resistance in a blast furnace is lower than for conventional form coke.

Title: Balance type dispenser of fluid doses - has retaining walls in fluid chambers controlling duration of dose emission
IPC: G01F3/26
Filed: 1977-01-12
Abstract: A liquid dispenser of the balance type dispenses measured volumes of liquid from one of a pair of chambers (119, 120) disposed at opposite sides of a dividing wall (121). The chambers may pivot about a horizontal axis (118) between bi-stable locations abutting adjustable screw stops (133, 134). A liquid inlet (113) fills each chamber alternately as the balance tips from side to side. During the filling of one chamber fluid leaves the other through orifice (127, 128). The flow out of the chambers is controlled by the provision of site walls (125, 126). The number of cycles through which the dispenser passes is monitored by a counting apparatus. Liquid leaves the dispenser through a conduit in its base under the action of gravity.

Title: Sepg. sulphur oxides from gases - by contacting with active solid contg. e.g. copper, partially oxidised, increasing efficiency
IPC: B01D53/81
Filed: 1977-01-18
Abstract: A process for sepg. oxides of sulphur from gas mixts. contg. them and contg. also oxygen, e.g. furnace gases, consisting of contacting the gas mixt. with a sorption solid contg. an active constituent, incorporates oxidn. of a part of the active constituent after regeneration and before sorption. The process may be carried out using several sorption beds in a cycle of sorption and regeneration. One of the beds is used for sorption while other beds are being regenerated. The oxidn. may be carried out using the treated gas from the sorption beds. About 35% of the active matl. should be oxidised. The process is partic. effective in cyclic sorption operations using copper, vanadium or a mixt. of vanadium and potassium, or an inert support e.g. alumina. The process achieves a greater recovery of sulphur oxides from gas mixts. contg. them than existing processes.

Title: Binary controlled AC supply regulator - uses 7 transformers to provide voltage components as required according to input 7-bit binary number
IPC: H02M5/10
Filed: 1977-10-19
Abstract: The current controller comprises 7 transformers (T1-7) with secondary windings providing 64, 32, 16, 8, 4, 2 and 1 volts. Each primary is controlled by two electronic switches (I) of which one is conducting and the other is non-conducting. These switches are controlled by a 7-bit binary logic system so as to provide any required voltage up to 127 volts. Thus if the binary counter is set to 0000011, transformers T6 and T7 operate to give 3 volts. 1111111 set on the counter gives an output of 127 volts.
