Title: Improvements in and relating to storage equipment
Inventor: RINGWOOD MICHAEL JOHN CHARLES
IPC: B65G1/06
Filed: 1963-08-14
Abstract: 1,107,211. Conveyers; pallets. ACROW (ENGINEERS) Ltd. 23 Sept., 1964 [14 Aug., 1963], No. 32207/63. Headings B8A and B8H. [Also in Division A4] Storage equipment for pallets comprises openended tracks which extend from one side of the equipment to the other, reciprocating drive means being provided to move the pallets stepby-step. U-shaped tracks 8 have wheels 10 on which pallets 12 run and each pair of tracks forms a lane. A number of lanes may extend one above the other and side by side. Reciprocating drive.-An hydraulically operated actuator 18 is connected to a carrier 28 having pairs of fingers 36 pivotally mounted on it, the fingers being counterweighted so as normally to be biased to engage pallet driving bars 16 as shown in Fig. 2. On the return stroke of the actuator and carrier 28, the fingers 36 pivot to clear the driving bars 16, ready to assume the driving position for the next forward stroke. Modifications.-The fingers 36 may be actuated by direct connection through rods or levers and the movement of the pallets may be controlled by manual or automatic control equipment. In Fig. 3, each finger 36 is held in the driving position by a spring-loaded plunger 50, the strength of a spring 54 being such that the finger remains in the drive position to move the pallets during all normal circumstances. If a lane is blocked, the plungers 50 overcome the pressure of the springs 54 so that no damage to the pallets or hydraulic drive system occurs and the fingers pivot in a clockwise direction to move under the drive bars 16.

Abstract: Mixtures of hydrocarbons e.g. C1-C6 paraffins are separated or dehydrated and moisture and liquid hydrocarbons are removed from natural gas by passage through a bed of solid porous adsorbent material, the bed comprising a first zone having at least 45% volume porosity and an average pore diameter of 30 to 100 A and a second zone having an average pore diameter of less than 30 <\>rA.  The second zone preferably has a per cent volume porosity less than that of the first zone and an average pore diameter of 15 to 25 <\>rA. The adsorbent may be in the form of a single bed comprising two zones or the zones may occupy separate beds; either bed may be stationary or moving.  Adsorption takes place at - 70 DEG  to 200 DEG F. and 0 to 2000 p.s.i.g.  Examples 2 to 4 describe the separation of pentane from methane at 80 DEG F. using silica-alumina, activated alumina and silica magnesia beds.ALSO:One or more components are separated from gaseous, vapour or liquid phase streams by passing the stream through a bed of solid porous adsorbent material, the bed comprising a first zone having at least 45% volume porosity and an average pore diameter of 30-100  and a second zone having an average pore diameter of less than 30 .  The second zone preferably has a per cent volume porosity less than that of the first zone and an average pore diameter of 15-25 .  The adsorbent may be in the form of a single bed comprising two zones or the zones may occupy separate beds; either bed may be stationary or moving.  Applications include the recovery of volatile solvents, dehydration and recovey of hydrocarbons from natural gas, removal of hydrogen sulphide from natural gas, selective separation of hydrocarbons, drying of organic liquids, and the dehydration of natural gas, hydrocarbon streams or air.  Specified temperatures used are -70-200  DEG F. and pressures may vary from atmospheric to 2,000 p.s.i.g.  The linear flow velocity downwardly or upwardly through the adsorbent may be 0,5-600 feet per minute.  The examples describe (1) the removal of moisture from an air stream of 80% relative humidity by passing the stream through an adsorbent bed comprising two zones of silica-alumina of average pore diameter 31  and 22 , (2) the separation of pentane from methane using silica-alumina, activated alumina and silica-magnesium beds at 80  DEG F.

Title: Improvements in high pressure hydraulic stop valves
IPC: F16K39/02
Filed: 1938-11-08
Abstract: 521,103. Hydraulic stop valves. TAYLOR, A. W., TAYLOR, A. H., and SADLER, P.V., [trading as TAYLOR & CO., A. W.]. Nov. 8, 1938, No. 32323. [Class 135] An hydraulic stop valve is balanced for flow in either direction and has the valve member loosely secured between a collar on the actuating spindle and a nut screwed thereon so that relative movement is permissible when the valve member engages its seat and so prevent scoring. In the form shown the valve member D co-operates with a removable seat C and is slidably mounted in a sleeve formed on the underside of a stuffing box K. Leakage past the valve member is prevented by cup-leathers J held in place by a cover pla'te D' and distance piece Q. The valve member is loosely held by a nut G against a collar F on the valve spindle, which collar is chamfered at f to co-operate with a similar surface on the bottom of the stuffing box to provide an additional leakage preventing device. The chamber above the valve member is connected to the space below by passage-ways L in the valve spindle so that the member is always in a state of hydraulic balance.

Title: New or improved selective circuits for use in connection with alternating currents
IPC: H03H7/46
Filed: 1920-11-18
Abstract: 180,349. Potter, E., (Pernot, F. E. and Rich, L. J.). Nov. 18, 1920. Filter, rejector, and separator circuits.-In multiplex signalling systems &c., networks of impedances, such as those shown in Figs. 1 and 2, are utilized as units for enabling (i) the separation, in sequence, for subsequent utilization, of each component frequency of a complex current, and (ii) the combination of currents of different frequency. For example, by adjusting the values of the impedances in Fig. 1 so that for a given frequency Z1 Z4=Z2 Z3, the given frequency will not pass from the leads O, O<1> to the leads l, l<1>, whereas currents of all other frequencies will so pass. Similarly, by suitably adjusting the value of the mutual inductance between the coils L, L<1>, and the capacity C, in the arrangement shown in Fig. 2, any given frequency can be stopped without affecting the passage of other frequencies. Fig. 6 shows an arrangement of units A - - II, each similar to that shown in Figs. 1 or 2, for separating out the different frequencies f1 - - f4 of a complex current supplied at O, O<1>. The frequency f3 is eliminated by the unit A, and f4 at B, whilst the units C and D separate the remaining frequencies, f1 appearing solely at the terminals l, l<1>, and f2 solely at the terminals 2, 2<1>. Similarly, in passing through the branch E, F, G, H the frequencies are so acted upon that the frequency f3 appears solely at 3, 3<1>, and f, at 4, 4'. The arrangement may also be used to combine a number of separate currents of different frequencies into one complex current. Specification 178,873 is referred to.

Title: A device for imparting intermittent rotational movement to a table or other rotatable object
IPC: F16H27/02
Filed: 1953-11-26
Abstract: 741,463. Ratchet gearing. NAAMLOOZE VENNOOTSCHAP BETONFABRIEK DE METEOOR. Nov. 26, 1953 [Dec. 31, 1952], No. 32892/53. Class 80(3) An intermittent driving device for rotating a table or other member 1 in steps comprises a driving pawl 17 and a stop pawl 16 both mounted upon a pivoted arm 13 which is actuated by the piston of a compressed air cylinder 25 when a movement of the table 1 is required. The pawl 17 is pivoted on side plates of the arm 13 at 18 and is loaded by a spring 19 to grip, when the table is stationary, a stud 5 of the table between it and the stop pawl 16, as shown in the Figure. On admitting compressed air to the cylinder 25 through a suitable valve controlled by a pedal, for example, a downward movement of arm 13 with pawls 17 and 16 is effected. The pawl 16 moves away from stud 5 and the pawl 17 swings inwardly against the pressure of spring 19 until a shoulder 30 thereon contacts the stud 5. A rotary movement is then imparted to the table 1 through pawl 17 until the stroke of the operating piston is completed. The rotation of the table continues owing to its kinetic energy and the stud 5 moves clear of the pawl 17 which then returns to its initial position. The operating air pressure is then released, preferably automatically, and the arm 13 also returns to its initial position by air pressure to the opposite end of cylinder 25 or by spring pressure. Another stud 5 of the table 1 will then approach the pawl 17 and striking its surface 32 will move it inward and be stopped by the pawl 16. The arm 13 may swing a little from its initial position shown to cushion the impact of stud 5 but will be immediately returned by the air or spring pressure to locate positively the table. A further operation can then be initiated by the operator. The pawl device may operate by a linear movement instead of a swinging one or a plurality of pawl devices may be arranged on a rotary disc which is stepped around to bring such devices into successive operation.

IPC: H03K3/537
Filed: 1958-10-15
Abstract: 876,789. Valve pulse generating circuits. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. Oct. 15, 1959 [Oct. 15, 1958], No. 32937/58. Class 40(6) A pulse generator comprises a number of pulse reforming networks which can be simultaneously charged from a common source, and individual discharging means which can -be operated in sequence so that the networks discharge into a common load. A number of delay lines 1, 2, 3 having the same characteristic impedance, are charged through chokes L1, L2, L3 from a common supply. If the spark gaps Tl, T2, T3 are fired in turn, the lines discharge through the common load R. In order to maintain the gaps ionized for sufficient time for all the lines to discharge CR networks Cl R1, C2 R2, C3, R3 are provided across each gap. Figs. 1, 2 show alternative arrangements of the circuit, and Fig. 3 shows a modification of Fig. 2 in which the spark gaps subsequent to the first are triggered by delaying the triggering pulse of the first spark gap through delay lines Dl, D2. The circuit of Fig. 1 may be modified, at higher p.r.f.'s, by connecting the spark gaps through transformers so that they may be maintained at earth potential.

Title: Improvements in or relating to electrical circuit arrangements for producing pulses
IPC: H03K5/01
Filed: 1960-09-26
Abstract: 903,326. Circuits employing bi-stable m-gnetic elements. SIEMENS & HALSKE A.G. Sept. 26, 1960 [Sept. 25, 1959], No. 33024/60. Class 40 (9). A magnetic core M is linked by windings W3, W4 with two transistors T1, T2 so that one transistor T1 conducts as the core is switched in one direction and the other transistor T2 conducts as the core is switched in the other direction by control windings W1, W2. The transistor transmit pulses of opposite polarity in the output current J3 at point P. In Fig. 3, the core may be switched and restored to give positive and negative output pulses at point P by applying a pulse to a control transistor T3. Both transistor T1, T2 are normally biased to cut-off by clamped potentials taken from resistors R1, R1<SP>1</SP> and R2, R2<SP>1</SP>, connected to voltage sources U2, U2<SP>1</SP>, U1, U1<SP>1</SP>. Voltage U2<SP>1</SP> is more positive than U2. A biasing current J1 through rectifier D2 and winding W1 normally holds the core in one state. A control pulse applied to transistor T3 drives a current J2 through winding W1 to reverse the state of the core. At the end of the pulse, the bias current restores the core. In a modification, the biasing current J1 is cut-off when reversing current J2 flows. Four switching arrangements like Fig. 3 operate in pairs to drive four rows of a matrix. The two switching arrangements of a pair are at opposite ends of a row.

Filed: 1965-08-02
Abstract: 1,098,619. Cable grips. ELECTROTHERMAL ENGINEERING Ltd. July 28, 1966, [Aug. 2, 1965], No. 33034/65. Heading H2E. [Also in Division E2] A device for clamping an elongate member for example an electric cable 13 comprises first and second parts 1, 7 each formed with a first hole through it for the elongate member to pass through, the first part being formed with a second hole 6 through it and a second part being formed with a second hole in it, the distance between the axis of the second hole and the nearest side of the first hole being less in the case of one part than it is in the case of the other part, the device further comprising a fastening member 14 which can enter the two second holes and can be used to draw one of the first and second parts towards the other, whereby if a said elongate member of sufficiently great width is passing through the first hole the material of one of the first and second parts bounding one side of one of the first holes and the material of the other of the first and second parts bounding the opposite side of the other first hole will press against opposite sides of the elongate member so that the latter will be clamped. In the construction shown the first part 1 is provided with a channel 4 which receives an edge of the other part to hold the two parts together on the sides of the first hole which are remote from the second holes. The first part 1 is moulded from polypropylene and comprises a rectangular flat plate-like portion with a circular boss 3 projecting from one face of it, the channel 4 extending from one of its shorter edges; the boss 3 is intended to pass through a hole in a panel 10, the panel also being provided with a hole through which the fastening member 14 can pass. The second part is a rectangular plate of resin bonded fibrous material and the first hole is serrated on the side of the hole which engages the elongate member although both sides can be serrated if desired or the serrations can be omitted; the fastening member 14 is a self-tapping screw and when it is engaged with the hole in the part 7, it cuts a thread so that the two parts are drawn together. In a modification the two parts are made in a single moulding operation and are connected by a thin and flexible portion adjacent the second holes. Instead of the part 1 being separate from the apparatus with which the clamping device is to be used the part 1 can form part of a panel of the apparatus in which case the boss 3 is omitted.
