Title: Improvements relating to domestic hot and cold water systems
Inventor: HASLEHURST ARTHUR KINDER
IPC: F24H9/12
Filed: 1956-04-26
Abstract: 827,659. Supply and delivery arrangements for hot water storage tanks. PARAMATIC DEVELOPMENT Ltd. July 25. 1957 [April 26, 1956; Nov. 20, 1956], Nos. 12767/56 and 35383/56. Class 64(1) [Also in Group XXIX] When a valve member 23 is in the position indicated in Fig. 2 (which shows the valve casing 20 with a cover removed) cold water from a supply pipe 28, Fig. 1. enters through a rear inlet, Figs. 3, 4 (not shown), and through a passage 30 of keyhole section, into a valve chamber formed by the valve cover, then passes to a delivery pipe 38, e.g. over a wash basin or sink. The valve casing 20 is secured to the bottom of a storage tank 10 in which water is heated, and when a lever 25 is moved to turn clockwise a spindle 24 and the valve 23 mounted on it, the passage 30 is closed so that the cold water then passes up a passage 31 into a pipe 32 in the tank and down through a surrounding pipe 33 to an opening 34 into the tank. This displaces hot water into an open-topped pipe 35 which passes it to passages 36, 37 in the casing 20 and, since the passage 37 is opened by the rotation of the valve 23, the hot water passes to the valve chamber and delivery pipe 38. At intermediate positions of the valve 23 the passages 30, 37 are both partly open and mixed hot and cold water is delivered. No reference is made to complete shutting-off of the water. Closure of the passage 37 obviates dripping when the tank water expands, while openings at the top of the inlet pipe 32, the height of the outlet pipe 35 and the positioning of the passage 30 above the delivery pipe 38 ensure against back-siphoning if the supply pressure falls.

Title: Improvements in weighing machines
IPC: G01G1/26
Filed: 1923-05-12
Abstract: 215,958. Pulz, W. May 12, 1923. Loose-weight apparatus. - In a weighing machine wherein the load is balanced by the addition to the weighbeam of weights arranged in sets each set corresponding to a. figure position of the decimal or other system employed, equilibrium is indicated by means of a finger directly mounted on the weighbeam and adapted to register with a fixed point on the framework. Four sets of weights are suspended from the scale beam, 2, Fig. 1, and each set is operated by mechanism similar to that shown for the set 4. This mechanism comprises in each case a handle 9, segment 8<1>, rack 8 and a lifting plate 4b whereby the weights may be placed upon or removed from the scale beam in succession. Another set of handles may be adjusted to indicate the price of the goods at apertures 12, 16, and simultaneously to set type discs. Quadrants 11, 15 indicate the weight. The mechanism for operating the weights may automatically set adding devices, counting devices, multiplying devices and the like. Printed records, apparatus for giving.-A rack 13<1> carried by the weight-lifting plate 4b operates a type disc 14 situated adjacent to the type discs for the remaining weights and for the price. A printed record is obtained in duplicate by turning a handle attached to a shaft 17 bearing a cam 22. The cam causes two printing blocks 18, 19 to grip the type discs to produce a printed record on two strips of paper. Continued rotation of the handle severs one strip (not shown) to deliver a ticket, the other strip 24 being retained in the machine. A sliding poise on the scale beam is used for balancing the tare and the following devices are used to prevent a printed record being obtained unless the tare poise is in the zero position. Normally the printing handle 17a, Fig. 5, is locked bv a rod 37 but is released when the rod is pressed in bv a knob 38. The movement of the rod 37 is however obstructed by a slide 39 connected through a cam 41, Fig. 4, to the actuating mechanism of the. tare poise so that only in the zero position of the poise is the slide removed. Taring devices. The tare poise 29, Figs. 4 and 5, is adjusted by a handle 32, shaft 35, gear wheel 31 and a rack 30. Normally the gear wheel 31 is out of gear with the rack 30 to avoid interference with the oscillations of the scale beam 2, but the gear wheel is moved into mesh by pressing in the handle 32. When the shaft 35 is rotated to adjust the tare poise a cam 36 displaces a catch 34, and an indicator 33 falls and indicates that the poise is in use. The indicator is raised again to indicate that the poise is at zero, by a link connection with the rod 37.

Title: Improvements relating to temperature-control apparatus
Inventor: SAUNDERSON DAVID MERVYN
IPC: G05D23/20
Filed: 1961-04-10
Abstract: 931,357. Automatic temperature control. J. STONE & CO. (DEPTFORD) Ltd. April 2, 1962 [April 10, 1961], No. 12863/61. Class 38 (4). Temperature-control apparatus for use with heating and/or cooling equipment, e.g. in railway vehicles or aircraft, comprises a temperature-detecting diode having a back resistance which falls from a high value with increased temperature, the diode being connected in one arm of a bridge circuit whose output is applied to control conduction through a thermionic or semi-conductor device which, in turn, controls heating and/or cooling means. As shown, a bridge network comprising the two limbs of a potentiometer 3, a fixed resistor 4 and a temperature-sensitive diode 1 is connected over a rectifier 5 to a supply derived from a transformer 7 which also supplies a thyratron 13 in the anode circuit of which is a relay winding 16 with normally-open contacts 17 controlling the energization of electric heaters 18. The control grid 11 and the cathode 12 of the thyratron 13 are connected across the output 9, 10 of the bridge network. If the temperature to be controlled is below a predetermined level, set by the adjustment of potentiometer 3, the back resistance of diode 1 is high; the control grid 11 will go positive and the thyratron will fire, thus providing sufficient current in the anode circuit for the relay to hold contacts 17 closed and heaters 18 energized. As the temperature rises the back resistance of the diode 1 and the grid positive voltage will fall so the thyratron fires later in each cycle, i.e. the mean anode current will fall. A limit is reached when the thyratron will not fire, and the relay contacts will then open to de-energize the heaters 18. When the temperature falls below the predetermined level the reverse action will occur. A silicon controlled rectifier may replace the thyratron 13, the relay being dispensed with and the current supplied to the heaters 18 being controlled directly by the rectifier. The controlled current may be supplied to refrigerating means instead of to the heaters 18.

Title: Improvements in or relating to processes for the separaton or recovery of gases and vapours by solid absorbents
IPC: B01D53/04
Filed: 1926-05-28
Abstract: 270,099. Godel, A. May 28, 1926. Gases, separating mixtures of. - Solid adsorbents such as carbon or silica gel used for separating gases or vapours are freed from the adsorbed substances by steam in such a way as to conserve a part of the latent heat of the steam usually lost by condensation. In one method two or more separators F, F1 are connected in series as regards the steam supply, with a superheater S or S1 in advance of each separator. A single condenser R and liquid-separator A are provided, but a drain cock may be arranged at the outlet from the first vessel. During the absorption stage the separators may be connected in series or parallel with supply and escape pipes T, T1. In a modification, steam leaving a single adsorption chamber is re-compressed, for instance by an injector, and re-introduced into the superheater and chamber. From the closed circuit thus produced a part of the steam is continuously removed for recovery of the substance adsorbed. In a second method, the heat of condensation of steam issuing from an adsorption chamber is employed to evaporate a fresh supply of water, or to re-evaporate the condensate itself, after removal of the substance adsorbed; the secondary steam generated is employed in another adsorption chamber, which may be the first of two chambers arranged 'as in Fig. 2. The apparatus may then be of the multiple-effect type; or the secondary steam may be compressed before use. Steam at different pressures may be superheated through equal ranges of temperature. Saturated steam may be employed, if the absorption chambers are preliminarily heated by other means. The adsorption chambers, or the later ones of a series, may be under reduced pressure during steaming, to avoid overheating of the substances recovered, which may be volatile solvents such as benzol, gasolene, &c. Two or more adsorption chambers may be arranged within a single casing. Specification 239,889 is referred to.
