Title: Electrostatic coating apparatus
IPC: B05B13/04
Filed: 1971-04-19
Abstract: 1347392 Electrostatic coating RANSBURG CORP 19 April 1971 [17 March 1970] 24388/71 Heading B2L [Also in Division F1] An electrostatic coating apparatus comprises two rotating coating discs 16, 36 and hydraulic drive means 26, 46 for moving the discs transversely to the direction of motion of the article to be coated and a synchronising system 51 for controlling the movement of one device relative to the other in order that a minimum distance is retained therebetween. An article 11 to be coated is carried in a circular path around the coating heads and is maintained at earth potential. The coating heads are rotated by motors 17, 37 and are fed with coating material from supply tanks 19, 39. Each coating head is moved vertically by hydraulic piston and cylinder arrangements 26, 46 so that both move in synchronism. When they are to be moved downwardly a pump 52 feeds pressure fluid via pipe 55 to the upper end of cylinder 45 so that its associated piston 43 moves downwardly. Fluid from below the piston 43 is pumped via a pipe 58 to the upper part of cylinder 25 thus forcing down the piston thereon. Excess fluid from below the piston 23 returns via pipe 53 to the reservoir 50. The limits of traverse of the piston rods are detected by micro switches. If, during downwardly movement it is detected that the lower disc has arrived before the upper coating disc then this unbalance is detected by the means 51 and the upper coating head is allowed to move down before the upstroke begins. During the downward stroke the motor 46 acts as the driving motor and the motor 26 is driven. During the upstroke the roles of the motors are reversed.  Synchronising arrangements: Switches 81, 82, 83, 84 are connected to the appropriate solenoids of the solenoid operated four way valves (Fig. 2). To start upward movement fluid is pumped through valves 63, 70 to fluid motor 26 and fluid from the other side of the piston in motor 26 actuates motor 46. When disc 36 reaches its upper limit switch 81 is actuated. When disc 16 reaches the upper limit switch 83 is actuated and valve 63 is energised to connect pump 52 to motor 46 and downward displacement takes place. Switches 84 and 82 are then actuated in sequence to again reverse the motion. If on the upward stroke switch 83 is actuated before switch 81 the appropriate part on valve 70 remains closed so that piston rod 24 cannot move but movement is allowed in motor 46 so that switch 81 can be operated so that the discs are again in register. Similarly on the downstroke the discs can be put into register. A modified form of synchronising means is described in respect of Fig. 3 (not shown).

Abstract: 1,170,208. Regenerating desulphanisation catalysts. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 22 May, 1968 [25 May, 1967], No. 24426/68. Heading B1E. [Also in Division C5] A process for the regeneration of spent sulphidic catalyst with the aid of oxygen or an oxygen-containing gas mixture which is first supplied to an initially closed reaction system at a pressure lower than the actual regeneration pressure and when the regeneration pressure has been reached is subsequently supplied to the system while spent gas is bled off from the system in such an amount that the desired regeneration pressure is maintained, in which process the reaction system containing the spent sulphidic catalyst is filled with dry, inert gas (i.e. containing no added steam) at a temperature lower than the regeneration temperature until a pressure not exceeding 10 atm. is reached, whereupon the pressure in the system is increased by heating the inert gas, with recirculation, to such a temperature that the regeneration of the catalyst is initiated during the subsequent supply of oxygen or an oxygencontaining gas mixture to the reaction system. The present process discharges very little HIS into the atmosphere, the greater part of the sulphur being retained at the carrier as sulphate. Nitrogen is the preferred inert gas. Sulphidic catalysts specified are Group VI and/or Group VIII metals deposited on carriers such as SiO 2 , Al 2 O 3 , ZiO 2  and MgO, e.g. Co-Mo on Al 2 O 3  Ni-Mo on Al 2 O 3  and Ni-W on SiO 2 -Al 2 O 3 , which catalysts may also contain halogens such as F.

June 27, 1962 [July 5, 1961], No. 24653/62. Heading B6H. [Also in Division B8]  Upright letters m, carried horizontally by an endless belt a running over pins f and driven by an endless band b, have their direction of motion changed to the vertical by a rotating conical disc h, the circumferential speed of which is the same as that of the belt a as they are both driven by a roller i. The letters m are fed to the disc h and initially gripped by a roller g pressed against the base of the disc h with its axis at an acute angle to the leading edge of the latter m and then gripped by a second roller j halfway up the conical surface. Under the influence of these rollers g, j the letters m partake of the rotation of the disc h and are fed from the disc h by two rollers k, driven independently of the disc h, against which they are pressed by a spring o. A threshold l is provided to initiate turning of a heavy letter, since the rollers g, j are adjusted for light letters, and a catch plate d prevents overturning.

Title: Record player
IPC: H04N5/781
Filed: 1956-08-13
Abstract: 812,441. Gramophones &c. ELECTROACUSTIC G.m.b.H. Aug. 13, 1956 [Aug. 11, 1955], No. 24756/56. Class 40 (2). A gramophone record player adapted to play records of differing sizes has a feeler device in which a member 1 feels the edge of the uppermost record on the turntable 15 and pneumatically actuates a stop-member 5 so that the stop member guides the pick-up stylus into the leadin groove of the record to be played. The member 1 is a square-sectioned tube movable vertically through a bushing 2 which is rotatably mounted in a plate 3. The bushing carries a spring arm 4 pressed against the sliding stop member 5, so that as member 1 is turned the member 5 is displaced. When the uppermost record on the turntable 15 has been played, the tone arm swung out and a further record been thrown off, a control member 14 lifts the member 1 and swings it inwards to the zone of the smallest record to be played and then lowers the member 1 until a guide pin 7 rests on the record to be played. As the member 1 is raised, a cam disc 13 compresses a bellows 9 forcing the air through a tube 10 and member 1 and a valve 6. At the same time the cam 13 tips a lever 11 to free the stop member 5 which moves into contact with a stop 17. Cam 13 leaves the bellows 9 in which the pressure is reduced and the control member 14 moves the member 1 outwardly until the pin 7 passes over the edge of the record, the member 1 is then lowered and a pin 8 shorter than pin 7 touches the record and thereby opens the valve 6. The entering air inflates the bellows 9, which then tilts the lever 11 so that a brake lining 12 arrests the stop member 5. The member 1 swings further outwards to the rest position and the tone arm moves inwardly until a lever 18 rigidly attached to the arm contacts a cam surface 19 of the stop member 5, the arm then being positioned above the edge of the record. On lowering the arm, when the stylus reaches the record groove, the lever 18 is below the stop member 5 so that the tone arm can swing freely. In a modification, the feeler device swings below the stack of records and the tilting lever acting on the bellows is controlled by a spring. The valve construction may be a head 29, Fig. 6, of rubber or other flexible material mounted on the tube 1 and having a bore 30 and a projecting resilient tongue 31, with a pin 7 extending from the lower surface. When the pressure in the tube is reduced, the tongue 31 is sucked against the bore 30 and prevents the entry of air until pulled away by contact with the record. In Fig. 7, the head 32 encloses a flexible tube 33 connected at one end to tube 1 and closed at the other end. A slot 34 in tube 33 closes when the pressure inside falls and is forced open by contact of a pin 8 with a record.

Title: Gas-fired instantaneous water heaters for domestic supply and central heating
IPC: F24D3/08
Filed: 1976-06-25
Abstract: 1507995 Gas fired water heaters for domestic supply and central heating BRITISH GAS CORP 25 June 1976 [10 June 1975] 24820/75 Heading F4A A water heater comprises a heat exchanger 23 through which pass a pipe 3 for the instantaneous heating of domestic water and a branch of a central heating circuit, a gas fired burner 2 which receives gas via line 1 and at least one fluid controlled gas valve, a variable speed burner fan 13, a pump 10 for the central heating circuit, a fluid controlled valve 8 which can divert central heating water to by-pass space heaters 26, thermostats to measure the domestic and space heating water temperatures, and a flame sensing device. As shown there are two gas valves 12, 16 in series and they are controlled in response to central heating water pressure differentials measured across the pump 10 and heat exchanger 23 respectively. The valve 8 operates in response to domestic water pressure differential across the heat exchanger to by-pass space heaters 26 when domestic water is turned on. The heater is controlled by control box 11 and central heating demand is met only after domestic water demand has been satisfied. When a domestic tap is opened the water temperature, detected by thermostat 14, is reduced if necessary to below 60 C. by the operation of a mixer valve 4 . The flow of water operates the valve 8 and a switch associated with this valve turns on the burner ignition circuit and the pump 10. Water pressure across the pump opens gas valve 12 and the fan is turned on. When the fan has blown air through the burner for a predetermined short period a solenoid valve 15 closes allowing gas valve 16 to be opened by water pressure across the heat exchanger. The burner is ignited and the fan speed is adjusted to approach the preset water temperature of 60 C. and the fan is turned off and solenoid valve 15 opened when this temperature is reached. When no flame is sensed the fan is turned off, the solenoid valve 15 opens, and the pump is turned off and the heater must be reset manually. A high temperature detected at 22 effects a similar shut-down. Time clock X and room thermostat 25 initiate central heating demand and the demand causes the pump to be turned on. Thereafter the system functions as described above with the fan speed set to minimum and the fan turned off and solenoid valve 15 opened when a central heating water temperature of about 82 C. is reached. The valves are all operated by the application of differential water pressure to a diaphragm and in the embodiment shown valves 12, 16 are in the form of two diaphragm operated valve members in the same valve casing (Figs. 2, 3, not shown).
