Title: Improvements in or relating to apparatus for handling articles
IPC: A21C15/00
Filed: 1961-08-17
Abstract: 1,035,803. Feeding dough; endless conveyers. SPILLERS Ltd., J. B. BARTHOLOMEW and P. P. MORISON. Aug. 14, 1962 [Aug. 17, 1961], No. 29668/61. Headings B8A and B8S. [Also in Division G1] Lumps of dough 11 are fed to weighing machine 42 by endless conveyer 12 which feeds them to endless conveyer 14 whence they roll down shoot 32 on to wheel 27. Wheel 27 is formed with four compartments into one of which a piece of dough is received, the wheel turns being controlled by light beam 36 so that the piece of dough is discharged into shoot 40 and thence received on pan 39 of weigh scales 42. Its passage down shoot 40 is noted by light beam 61 which signals the weigh scale to operate. When the dough has been thus automatically weighed the weighing machine signals the weigh pan 39 to cause it to pivot to the erect position shown so as to discharge the dough on to endless discharge conveyer 53. The movement of weigh pan 39 to the vertical position operates to cause wheel 27 to effect another quarter rotation so that the next piece of dough is delivered down shoot 40 to be weighed in the same automatic fashion. Thus the operation of wheel 27, of weigh scale 42, and of the discharge by the pan 39 is automatic, so that the pieces of dough are weighed singly despite the fact that they may be received with spacings very different. Alternatively the wheel 27 may be dispensed with and the automatic feeding to shoot 40 may be made by the movement of belt 14 under the control of light beams.

Title: A fluid control system for vehicle brakes
IPC: B60T11/20
Filed: 1963-07-26
Abstract: 1,041,845. Master cylinders. KELSEYHAYES CO. July 26, 1963 [Aug. 9, 1962], No. 29668/63. Heading F2F. A master cylinder in a fluid control system for vehicle brakes comprises a bore 11 having plungers 12, 18 with a pressure chamber 20 therebetween and having a spring 28 between the plungers, means 14 to operate one plunger 12, a second chamber 45 formed between the other plunger 18 and the end of the bore, each chamber having connections 75, 77 with a pair of vehicle wheel cylinders, the end wall of the second chamber having a fluid replenishing port 61, the other plunger comprising first and second elements axially movable relatively to each other, one element having a valve 58 movable to close the said port. The spring 28 between the pistons is stronger than a spring 50 disposed in the second chamber 45. On rupture of line 75 plunger 12 would move toward piston 18, after the latter had moved to seal port 61, compressing spring 28 until plunger 12 and seat 31 abut, further movement of the plungers generating pressure in line 77. If line 77 ruptures the plungers move left until a face of plunger part 40 abuts the end wall of the bore 11, further movement of plunger 12, as spring 28 compresses, generating pressure in line 75.

Title: Improvements in the manufacture of activated carbon
IPC: C01B32/336
Filed: 1937-11-01
Abstract: In the activation of carbon by means of gases using activating chambers operated in counter-flow in conjunction with chambers operated in co-current, the carbon is treated with activating gases in counter-current, and <PICT:0487819/III/1> <PICT:0487819/III/2> the gases resulting therefrom are withdrawn from two or more points in different zones of the chambers and are fed, with or without further heating, into one or more points or zones in the co-current chambers. Fig. 1 shows an arrangement in which the gases are withdrawn at the cool end 6 and an intermediate point 5 of the counter-current furnace 1 and are fed into corresponding temperature zones 8 and 7 in the co-current furnace 2.  Fresh activating gas is fed in at point 4.  A bridge pipe with valve 12, and also valves 10 and 11 are provided to ensure that an even flow of gases without local excess pressure and choking may be maintained.  Fig. 2 shows an arrangement in which gases from the cool end 17 of the counter-current furnace are fed into an intermediate and hotter zone 18 in the co-current furnace, i.e. at or near the activating zone, with intermediate heating 19 if desired and gases from an intermediate zone 15 of the furnace 1 are fed into the cool or drying zone 16 of the furnace 2 together with the fresh activating gases.  The arrangements are stated to prevent choking irrespective of the relative cross-sections of the furnaces or the moisture content of the raw material and to reduce the discharge of harmful and explosive gases from the counter-current furnace when recharging; to give more even temperature control and to enable the co-current furnace to be fed with gases of suitable composition and temperature.  The gases are preferably withdrawn and fed in at a number of points in each zone.  Suitable activating gases are steam and carbon dioxide with, if desired, free oxygen and gases such as chlorine or hydrochloric acid.  Specification 411,918 is referred to.

Title: Air conditioning plant for buildings
IPC: F24F12/00
Filed: 1971-06-29
Abstract: 1360064 Heat pumps; installations for heating or cooling air; air conditioning units RINIPA AB 29 June 1971 30516/71 Headings F4H F4S and F4V An air conditioning plant, for use particularly in heating and cooling buildings having stairways and cellars, includes evaporating and condensing heat exchangers which are designed in such a manner that they can switch function. In operation, incoming air to the rooms 10, 11 is divided between branch conduits 14, 15; outgoing air passing through conduit 16. Heat exchangers 20, 21, which form parts of a heat pump unit 9, are provided in the said conduits 16, 14 respectively. The heat exchangers are formed into a cylindrical drum 27, which is subdivided into a number of sector-shaped heat exchange packages 31-42. Each package, which is formed of a number of pipe coils provided with external fins, may function as a condenser or as an evaporator. The incoming air passes through the drum from below by way of an internal rotating distributer housing 25, while the evacuated air from conduit 16 passes the unit from above by way of an outer conical shaped housing 26. On the principle of a rotary regenerative heat exchanger, either the drum is stationary and the housing 25, having sectorshaped baffles 28, rotates, or vice-versa, preferably the housing rotates and simultaneously operates a valve arrangement. Consequently continuous defrosting will occur. Throttling conduits 45-48 between condensers and evaporators are in the core of the drum. The diametrically opposite sectors 31, 32 and 37, 38, operate in the position illustrated as evaporators, while sectors 34, 35 and 40, 41 operate as condensers. Sectors 33, 36, 39 and 42 are simultansously covered by the rotating plates 28. The refrigeration system includes a high pressure conduit 43, a low pressure conduit 44. Between each annular conduit and the various sectors there are branch conduits, each being provided with a valve, governed by the housing 25, in order to constantly switch the functions of the heat exchange packages. As shown, low pressure valves 36L and 42L are also open to drain the pertaining sectors 36 and 42 in preparation for the transfer of functions.

Title: Fluid flow control valves
IPC: F15B13/02
Filed: 1966-07-07
Abstract: 1,096,610. Valves. NEW YORK AIR BRAKE CO. July 7, 1966 [Aug. 26, 1965], No. 30564/66. Heading F2V. A spool valve controlling the operation of a double-acting piston is provided with auxiliary valves which by-pass liquid from one side of the piston to the other to prevent cavitation when the piston is moved by its load at a speed greater than that with which the supply pump can keep pace. The auxiliary valves may be contained in the spool valve housing (Figs. 1-4, not shown), or they may be mounted externally of the latter as shown in Fig. 5. In the latter, the housing 111 has an inlet 112, exhaust 113, carry-over port 114 and two sets of motor ports (not shown) controlled by respective spool valves 127, 127b. During normal operation, the pump discharge pressure acts via line 173 on a piston 168 to cause the latter to urge a throttling spool 142 to the left. In this position, spool 142 provides a relatively unrestricted passage 149 for liquid returning via exhaust line 113a to tank 77. A rightward bias on the spool 142 is provided by liquid in chamber 155, this chamber communicating via orifice 157 with the exhaust line 113a upstream of passage 149. A relief valve 161 maintains the pressure in chamber 155 constant. If the controlled piston should move at an uncontrolled rate, the supply pressure in lines 112a and 173 will fall and the spool 142 will move to the right to throttle the exhaust line. When the backpressure in the latter reaches a predetermined value, check valve 137 (Fig. 2) opens to by-pass liquid to line 173 to supplement the supply from the pump 75. In the modification of Fig. 6, not shown, the relief valve 161 and orifice 157 are omitted and the constant rightward bias on the spool 142 is achieved with a low-rate spring.

Title: Coordinate determining device employing a slowly varying difference signal to determine approximate cursor position
IPC: G06F3/033
Filed: 1972-06-29
Abstract: 1348866 Inductive signalling BENDIX CORP 29 June 1972 [6 July 1971] 30577/72 Heading H4U [Also in Division G4] The co-ordinate position of a cursor is determined by, in each direction, providing two signals which vary cyclically with displacement and have slightly different repetition distances, finding the phase difference between the signals and determining and indicating the difference therefrom. As described a cursor 12 moves linearly over two grids, the first comprising mutually insulated metal strips 34, 36 of spacing 1À00 cm. and the second, of slightly larger spacing (1À02 cm.) comprising strips 38, 40. The cursor is fed with a 3 KHz signal from generator 16 and the induced signal from strips 34, 36 is processed at 18 and compared with the reference signal in phase comparator 22. The comparator output is a pulse count proportional to the phase difference and, such that a phase difference of 180 degrees would have a count of 1000, and is stored in register 26. The induced signal from strips 38, 40 is similarly processed at 20, compared at 24 and stored in register 28. The value in register 28 is subtracted from that in register 26 in circuit 30 and the difference is fed to register 66 and divided by twenty in number generator 68, ignoring the remainder. The number in register 26 represents the position of the cursor between the lines of the first grid to 0À001 cm. and the output of divider 68 represents the number of first grid lines crossed, and hence the distance to the grid section in which the cursor is located. These values are added in summing circuit 70, and the displacement is displayed at 72. In a second embodiment, not shown, which compensates for errors in the difference value, all the possible absolute cursor positions are calculated corresponding to the "between grids value" in register 26. These are compared with the value in register 32 from the subtracting circuit and the nearest calculated value to the value in the register is displayed as the cursor position.
