Abstract: 1379500 Automatic control of temperature SAUNIER DUVAL 28 April 1972 [26 May  1971] 19897/72 Heading G3R In a heat exchanger type water heater (e.g. electric or gas) the withdrawal rate of hot water from a circuit B, Fig. 1, is measured by a flow-rate meter 3 at the cold water input side thereof and the temperature of heating water in a circuit A is measured by a thermistor 4 and compared, with a desired value thereof by a circuit 7. The resulting temp. difference value thus obtained is used at an amplifier 5 to modulate the pulse width of a square or sawtooth waveform signal from the flowmeter producing an output signal the frequency of which is proportional to flow-rate, the pulse width of which is proportional the temperature difference value and the mark/space ratio of which is a function of the product of flow-rate and temperature difference. The output of an integrator 6 is proportional to said product and is used to control a thyristor or transistor which in turn controls a gas valve (not shown) or an electric heating element. The flow-meter may comprise a turbine wheel with magnets which actuate a reed switch. It may be arranged that when the actual  temperature equals the desired temperature, the mark/space ratio is 1 : 1.

Abstract: 183,826. Schwarzenauer, W., and Cornehl, K. July 26, 1921, [Convention date]. Tidal energy, utilizing.-In installations of the kind in which air compressors of the trompe type are operated by tidal power and utilized for working compressed-air engines, collecting- basins are separated from the sea by means of dams, within which the air-compressing chambers and passages for the water are formed. The dam, Figs. 1 and 2, is formed with passages e, f, shafts o, u, and chambers s, a. By means of gates k, the passage f is connected with the shaft o and the passage e with the shaft u at high tide, and the passage f with the passage u and the passage e with the passage o at low tide, so that water always enters the chamber s and flows from the chamber a. By way of a vertically adjustable suction head c, water flows through the fall pipe h1, h carrying air with it into the chamber a, where it separates from the water and is compressed and from whence it is led by a pipe l to an air motor &c. In a modification, the pipes o, u, instead of being arranged at the sides of the pipe h, may be arranged in front and behind it and may be provided with siphons so that the chamber a may be entirely cut off from outside water by admitting air to the siphons. In the form shown in Fig. 4, telescopic tubes t1, t2 are arranged on opposite sides of a partition each leading to the compression chamber a and each provided with suction heads c, the position of which is adjusted by means of floats m, n. The tube, the head of which is at the higher level, serves as a full tube to carry air and water to the chamber a, while the other acts to discharge water from the chamber a.

Class 133 In a method of providing carrier bags with looped string handles 2 having protective grip means 3, a piece of material suitable for form ing the grip means is temporarily secured to the bag wall where a string handle is to be applied, holes are cut through the bag and grip means and then string is threaded through the holes and secured in a loop so that the grip means 3 is threaded on the looped handle and when detached from the bag wall is free to slide along the string. The bags are made from tubular lengths B which are presented in succession and edge-on to co-operating pairs of feed rollers 4 so as to travel side-wise. Each bag length is passed by the rollers 4 through adhesive applying rolls 6 fed from baths 7 and which apply dabs of adhesive 8 to the external surface of each side wall of the bag length adjacent the mouth, then the bag lengths B are drawn between feed roller 9 and roller 10 on to a horizontal supporting plate 14 towards stops 11 which are periodically raised to hold the bag length stationary between transverse guides 12, 13 which receive strips 15 of cardboard for forming the grip means 3 and vertically movable opposed presser plates 18, 19 above and below an opening 20 in the edge of plate 14 the plate 18 carrying a cutter 17 to co-operate with plate 19 and sever the strips 15 which are pressed into contact with the adhesive 8. Each bag length in turn is progressed by intermittently driven feed rollers 21 to intermittently driven feed rollers 23 of a punching station P having cutters 24 which cut holes through the bag and strip 3 and the bag lengths are then delivered to stringing mechanism (not shown). The method is also applicable to carrier bags having one string handle 2 and a slot 28 formed in the opposite wall of the bag mouth for engagement by the single handle. The grip pieces 3 may be attached to the bag by metal clips or the like instead of by adhesive and in a modification the pieces 3 are contained in magazines and supplied to the presser plates instead of being severed from continuous lengths.

Abstract: 771,585. Endless track vehicles. GENERAL MOTORS CORPORATION. July 14, 1955 [Sept. 14, 1954], No. 20388/55. Class 79(1). [Also in Groups XXIX and XXXII] An endless track tensioning mechanism comprises a piston and cylinder 20 adapted under fluid pressure to exert pressure against an idler wheel 10 and a pressure responsive device 44 adapted under recoil pressure to disconnect the normal pressure source 56 from the cylinder 20 which thereupon becomes effectively connected to a source 58 of higher pressure. As shown the idler wheel 10 of an endless track vehicle 2 is supported in a structure 16 slidable on rails 12 and engaged by a forked yoke 14 integral with the piston rod 18 of the cylinder 20 which is pivoted at 22. A pipe 38 interconnects the cylinder 20 and a T-pipe 42, one arm of which is connected by the device 44 in the form of a check valve and a pipe 54 to the normal pressure source 56 in the form of a hydraulic pump having a delivery pressure of approximately 100 p.s.i.

Abstract: 968,743. Transistor bi-stable circuits. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 28, 1962 [May 31, 1961], No. 20428/62. Heading H3T. The control circuit for a bi-stable trigger comprising a pair of transistors 1, 2, Fig. 1, with cross-coupled base and collector electrodes, is characterized in that diodes 5, 6 are connected in a forward direction between the emitters of each transistor and a source of voltage; a source of control pulses 9 is connected to the common point of the two diodes; and the common point of each emitter and its associated diode is decoupled by a respective capacitor 11, 12. In a modification, Fig. 2 (not shown), the transistors are prevented from bottoming by Zener diodes in the collector circuits connected to suitable bias supplies. Referring to Fig. 1, assuming that transistor 1 and diode 5 are initially conducting and transistor 2 and diode 6 cut-off, then a negative pulse at input 9 is fed through diode 5 to decrease the current in transistor 1, hence switching on transistor 2 and changing the state of the circuit. Curves V 21 , V 22 , Fig. 3, show the change in voltage across capacitors 11, 12 due to the initial step of the trigger pulse Vg. If the trailing edge of the pulse Vg occurs between times t 2 , t 3  both capacitors 11, 12 charge to maintain the new stable state of the circuit. Alternatively, if the pulse does not return to zero until after t 3 , but the capacitor 10 is charged by the current through resistor 8 during the time t 2 -t 3  to a valve such that at least diode 6 is forward biased, the new stable state is again maintained. Specification 942,405 is referred to.
