Patent GB-1578505-A (GB)
Title: Heat exchangers
IPC: F28D7/02
Filed: 1978-02-02
Abstract: The heat exchanger has a storage container (1) and a tube system, which is arranged in the latter and through which a heat-dissipating medium flows. In order to achieve the best performance of such a heat exchanger, it is important that, on the one hand, the heat-dissipating medium leaves the heat exchanger with the lowest achievable temperature and, on the other hand, that the temperature of the medium in the container which absorbs the heat is as uniform as possible over its entire volume. In order to achieve this, the tube system has a heating medium inlet distributor tube (4) situated at the top in the storage container (1) and an outlet manifold (5) situated at the bottom in this container, which are connected by a number of vertical tube elements which extend helically. Each of these tube elements has an upper part (7, 7') whose heat exchange surface is substantially smaller than the entire heat exchange surface of the lower part (8, 8') of the tube element. This heat exchanger is used, in particular, in the form of a hot water container for heating service water. <IMAGE>

Patent GB-737936-A (GB)
Title: Steam trap
IPC: F16T1/08
Filed: 1953-02-18
Abstract: 737,936. Thermally actuated valves. VELAN, A. K. Feb. 18, 1953, No. 4497/53. Class 135. [Also in Group XIII] A bimetal assembly 45, 46, 47 responsive to fluid pressure and temperature is mounted in a chamber 12 of a steam trap between inlet and discharge passages 14, 16 to engage and actuate a valve having, for closing on a seat 24, a bulbous head 32 on a stem 30 pivotally connected to the bimetal assembly with a loose fit, so as to be capable of radial movement relative to the valve seat axis and also capable of longitudinal movement and of rotation about its own axis. The bimetal elements 45-47 are spaced by shims 90 and secured by nuts 49 to a base 44. The inner end of the valve stem 30 carries an adjusting nut and an adjacent locking nut 33 next to an enlarged portion 31 which is a sliding fit in a hole 53 through a chamfered rocker 52 pivoted in a yoke 50 secured to the first bimetal 45. The adjusting nut provides means for setting the valve but, for running adjustment, a bifurcated wedge 70 can be raised or lowered between the nut and the rocker 52 by screwing an external cap 71 up or down so that, owing to the loose mounting of the valve stem 30, 31, the distance of the valve 32 from its seat 24 can be altered. The stem 30 passes freely through notches in the tops of the bimetals. In operation, upon heating, the tops of the bimetals 45-47 bend towards the inlet 14 to tend to close the valve 32 on to its seat, the bimetal 45 having first effect at low pressures and temperatures since it is secured to the mounting of the valve stem. As the pressure and temperature of the steam rise, the remaining bimetals 46, 47 bow successively a sufficient amount to contact their neighbour and add their power to hold the valve 32 against steam pressure. Accumulation of condensate cools and straightens the bimetals, so that fluid pressure on the valve 32 moves it to the open position and the condensate flows into the return line. The bimetal assembly is arranged so that its deflection characteristic follows that of the saturated steam curve. In practice, the bimetals 46-47 each comprise a number of bimetallic plates. Since the valve stem 30 is free to move axially until either the valve 32 is seated or the adjusting nut contacts the wedge 70, back pressure from the return line, in an outlet chamber 20, will move the valve 32 to closure so that it acts as a check valve, or, when starting from cold, air will be vented by its pressure moving the valve to an open position. A bimetal element thermometer 112 is screwed into the chamber 20. An observation glass 102 and a cylindrical strainer 124 are included in the casing.

Title: Improvements in or relating to multivibrator circuits
IPC: H03K3/33
Filed: 1960-02-10
Abstract: 948,139. Transistor bi-stable circuits. WESTERN ELECTRIC CO. Inc. Feb. 10, 1960 [Feb. 25, 1959], No. 4683/60. Heading H3T. [Also in Division G4] A bi-stable multivibrator comprises a pair of cross-coupled transistors, having at least one diode connecting the collector of each transistor to the base of the other, each transistor having connected to its base a circuit comprising the series combination of a diode and a storage device for applying triggering pulses. As described, Fig. 1, triggering pulses are applied to the base of the conductive transistor 21, say, by way of a " fast recovery " diode 40 and a storage element 45 which may be a capacitor or more preferably a " slow recovery " diode. Assume transistor 25 cut off, and the trigger pulse at its high potential value, diodes 40, 41, 42 are cut off, transistor 21 is held conductive by the current from source 48 through diode 43 and diode 45 is forward biased. When the trigger pulse takes up its low potential value, diode 40 becomes conductive and due to the slow recovery of diode 45, the drop in potential at the junction of 49, 45 is fed via the diode 45 to the base of transistor 21 to cut it off. The rise in potential at the collector cuts off diodes 41<SP>1</SP>, 42<SP>1</SP> allowing diode 43<SP>1</SP> to conduct and forward bias the base of transistor 25 from source 50<SP>1</SP>, thus switching this transistor on. Provision for presetting a counter using a number of such stages connected in cascade, may be provided by applying appropriate presetting pulses to diodes connected to points intermediate diodes 42, 43 and 43<SP>1</SP>, 431. Multiple triggering may be provided by additional input circuits in parallel with diodes 40, 40<SP>1</SP> and input lead 35. In a modified circuit, Fig. 3, multiple triggering is applied via the diodes 60 and the slow diodes 62, 62<SP>1</SP> and a connection is provided between collector and base of each transistor by diodes 65, 65<SP>1</SP>. PNP transistors may be used instead of NPN.

Title: Improvements in or relating to separators
IPC: B07B4/02
Filed: 1962-02-07
Abstract: 990,641. Mechanical separators. ZAKLADY KOKSOWNICZE VICTORIA. Feb. 7, 1962 [Feb. 7, 1961], No. 4731/62. Heading B2H. A separator for granular material comprises a feed hopper 1, with a vertical shaft 9 passing through the centre of the hopper, driven from a belt pulley 14, a rotor 4 on the shaft 9 having blades 5 arranged perpendicularly to its upper horizontal surface, and inclined to the radius of the rotor 4 and a stationary comb member arranged concentrically around the rotor 4. Material to be separated, e.g. moist coal of different size particles, is fed down the hopper 1 on to the rotor 4. The blades 5 are disposed round the edge of the rotor 4, so that the coal particles are thrown off the edge of the rotor 4. The coal particles then impinge on the comb member which may be either constructed of tensioned steel wires or synthetic fibres 7<SP>1</SP> stretched between rings 6<SP>1</SP> or may be constructed of vertically disposed plates 7, Fig. 4A, fixed to a ring 6. The plates 7 are disopsed at the angle at which the coal particles leave the edge of the rotor 4 and are spaced such that small particles pass between adjacent plates to fall into a chamber 16, whilst larger particles strike the inside edges of the plates 7, which are inclined at about 45 degrees to the horizontal and are deflected upwards into a chamber 17. Where wires 7<SP>1</SP> are used in place of the plates 7, these are also inclined to the horizontal. In an alternative embodiment, the plates or wires may be inclined downwardly away from the rotor 4 so that the smaller particles pass to the chamber 17 whilst the larger particles are deflected downwardly into the  chamber 16. This is shown in Fig. 1 where in fact two sets of wires 7<SP>1</SP> are provided one above the other. If the coal is moist then the smaller particles may stick together in which case they may only be broken up by impinging on the upper set of wires 7<SP>1</SP> but need not necessarily pass through. In this case they will be deflected down on to the lower set of wires 7<SP>1</SP> and the broken-up smaller particles can then fall into the chamber 17. Where two sets of plates 7 are used, the surfaces of the lower set are arranged radially with respect to the rotor. Furthermore, after passing through the single combs or vertically spaced sets of combs described above, the particles may be made to impinge on a similar comb or set of combs disposed radially outwards from the first mentioned or inner combs. The spacings in these outer combs are smaller than those in the inner combs so that the coal particles may be divided into three fractions. The height of the bottom edge of the hopper 1 may be adjusted relative to the rotor 4 in order to control the rate of passage of material through the apparatus.

Abstract: 755,247. Automatic lathes. SCHUETTE, A. H., COMMER, G., WELCKER, L., THEN, E., and PECHMANN, E F. VON., [trading as SCHUETTE, A. H.]. Feb. 18, 1954 [April 24, 1953], No. 4822/54. Class 83 (3). A safety device for automatic lathes operating on bar-stock comprises an automatic circuitbreaking device in the machine drive which is rendered ineffective when the bar stock is fed forward sufficiently to contact a stock-stop. The stock-stop 121 pivots about the shaft 12 under control of cam mechanism from the main control-shaft. In the operative position shown, the bar-stock 25, in one of the lathe spindles 111, engages it and forces it to the right against a spring 13 until a collar 122 engages a fixed member 14. A switch 24 carried by the end of shaft 12 is thus made to close a circuit in parallel with a switch 22, which is opened by a cam 231 at this moment, the cam also being carried on the main control-shaft 17. If there is insufficient stock left in the spindle 111 to operate the stock-stop and close switch 24, switch 22. renders a control circuit to the main driving- motor 19 inoperative and thus stops the machine.
