Abstract: 1286666 Electric clocks H OBERGFELL [trading as HENINGER & OBERGFELL] 20 Oct 1969 [19 Oct 1968] 51381/69 Heading G3T A synchronous motor clock or a timed cut-out alarm comprises a relay switching device for actuating means for indicating a current failure or a current-break. A synchronous motor 1, Fig.1. for driving a clock (not shown) is energized via a relay coil 2 by closing a push button switch 6. When the relay is energized a contact 9 is actuated to complete a holding circuit for the motor 1 and to extinguish a flow-discharge lamp 3. In the event of a current failure the contact 9 returns to complete the circuit of the lamp 3 which is illuminated when the current is restored. In an alternative circuit the relay coil 2 is in parallel with the motor 1, Fig.2 (not shown). In the circuit illustrated in Fig. 3 closure of the push-button switch 6 energizes the relay coil 2 to change over the contact 9 and after a predetermined period an interupter 7 is actuated by the clock movement to de-energize the relay coil 2. The contact 9 then returns to the position shown to energize a buzzer 3. Alternative circuits are described in which a buzzer is energized in the event of current failure or after operation of a current interupter.

Filed: 1975-12-16
Abstract: 1525978 Vapour - phase polymerization or a stirred, non-fluidized bed of polymer STANDARD OIL CO 16 Dec 1975 [16 Dec 1974 (3)] 51470/75 Heading C3P The temperature of a vapour-phase polymerization system is controlled by spraying a readily vaporizable quench liquid (which may comprise the monomer in liquefied form) on to a stirred, non-fluidized bed of particulate polymer, the off-gases comprising vapour(s) of the monomer and quench liquid being removed from the horizontal polymerization zone employed. The particulate polymer bed preferably is divided into two or more temperaturecontrollable sections. A reactor for use in the process is shown in Fig. 1, wherein weirs 110, 112, 114 divide the reactor into four sections, each of which is independently controllable in temperature by means of quench liquid introduced via inlets 153, 155, 157 and 159, and wherein vapour (including monomer) is recycled into the reactor via inlets 175, 177, 179, 181 at a rate (controlled by valves 191, 193, 195, 197) such that the particulate bed is not fluidized. The reactor is equipped with a rotating impeller drive shaft 104 (driven by motor 102), which runs the length of the reactor, and whose blades (not shown) serve to slowly turn over the polymer bed without causing it either to be thrown up in large quantities into the overlying gas space, or to migrate along the length of the reactor. In the examples, the monomers polymerized were ethylene and/or propylene, the quench liquids being isopentane or liquified propylene; hydrogen gas and organometallic initiators were also employed.

Title: Improved power lift system
IPC: A01B63/114
Filed: 1965-12-06
Abstract: 1,112,165. Tractor power lift mechanisms. ALLIS-CHALMERS MANUFACTURING CO. 6 Dec., 1965 [7 Dec., 1964], No. 5l570/65. Heading A1P. A tractor power lift mechanism is arranged to transfer weight from the implement to the tractor in dependence on the draft load exerted on the implement. In the neutral position shown the pump 2 delivers pressure fluid along conduit 44 to an inlet passage 31 from which the fluid passes past a spool valve 48 into outlet passage 28 which returns the fluid to the sump 7 via conduit 35. The pump 1, which is of larger capacity than the pump 2, delivers its output to the sump via conduit 55, spool valve 8, conduit 56 and internal passages 25, 27 and 28. Movement of the lower links 17 of the hitch linkage operates rod 18 to engage lever 21 with the spool valve 48 to move it to the left in the Figure. Land 24 of the valve thus closes the opening between passageways 26 and 28 whereby the output of the pump 2 is applied in conduit 58 to open non-return valve 59 and supply fluid via valve 8 and conduit 61 to the ram 3 to increase the pressure therein, thus transferring weight from the implement to the tractor. If, under a larger draft.load, the spool valve 48 is moved further to the left (Fig. 4, not shown) the centre land 65 throttles the opening between the internal passages 25 and 27 which thus increases the pressure in the output conduit 55 of the .pump 1 to open the non-return valve 63 and thus supplement the pressure fluid directed to the ram 3. A pressure relief valve 40 is incorporated in the passage 26 for the pump 2 and a relief valve 57 is associated with pump 1. An adjustable, restricted orifice 39 associated with internal passage 25 allows some flow of pressure fluid to the sump whilst the pump 1 is building up pressure to operate the valve 63.

[Class 74 (ii)] Relates to means for reducing the tendency of the cam shaft of a straight-bar knitting- machine to vibrate under load. The cam shaft 1 is driven by a motor 2 through toothed wheels 3 ... 6. The wheel 6 is mounted at about the middle of the shaft 1. If two loop-sinking devices 10, 12 are provided, they are located on opposite sides of the wheel 6, so that the driving torque is taken from the right and left of the wheel 6 from positions in immediate proximity thereto. The bevel pinions 9, 11 drive bevel wheels 13 mounted on the same shaft as sinker cams 14, which drive levers 16 attached to a slur-cock bar 20 or a thread-guide bar 21. The changing cam 22 is also located in close proximity to the drive. The cam shaft 1 may be driven at a number of points from a special auxiliary shaft. It may consist of a number of sections connected by couplings 24, including a solid part 1a, which carries the wheels 6, 9, 11 &c., and other, hollow, sections 1b, 1c of the same external and various internal diameters.

The original and final paths may be in alignment. The arrangement inhibits contaminant ejection from the workpiece and chamber to the gun. Voltage fluctuations and ripple, field strength drifts or temperature variations may be compensated. Three or four coils for example may be used (Figs. 2 to 3, not shown). Plates (26), (27) prevent direct passage of vapours. Plate (26) may be removable for initial alignment of axial components, the deflection systems remaining unenergized. The coils may be series connected and coil (20a) (Fig. 2) may have twice the turns of coils (18), (24). Alternatively, coil (20a) may carry twice the current. Fig. 4, and Fig. 5 (not shown) includes Cu coil housing 30, Cu drift tubes 36, 38, 40 and 42 coils (44), (46), and Cu anode cap (48). Mounting plate 50 extends across the generator sealing the upper portion from the lower. The drift tube path may be a gradual taper or stepped and facilitates maintenance of a higher vacuum in one end of the tube. Deflection angle changes for changes in accelerating voltages and coil currents are discussed (Figs. 7, 8, not shown).

Abstract: 1,187,707. Dispensing containers. PRODUCTS RESEARCH & CHEMICAL CORP. Nov. 13, 1968 [April 24, 1968], No.53898/68. Heading F1R. A container, for storing two ingredients separately and for mixing them prior to dispensing, comprises a plastics cylinder 12 divided by a frangible partition into compartments 22, 24. The partition is formed by aluminium foil 20 supported by a dasher 18, and is retained in position by adhesive tape 62 which constricts the cylinder to clamp the partition. The cylinder has a dispensing port 42 at one end and a piston 15 closing its other end. An operating rod 36 extends slidably through the piston 15 and is held retracted for storage and transport by a cardboard tube 34. Removal of the tube permits advance of the rod 36 to rupture the partition foil 20, further advance and rotation of the rod screwing it into the dasher 18. The tape 62 is then removed to release the partition, and the rod is retracted to displace the foil 20 against the piston 15. The dasher is then reciprocated to mix the ingredients. To dispense the contents the rod 36 is retracted to expose an annular groove 66 and then a locking sleeve 68 is pushed down the rod to engage inturned portions 70 of locking fingers 72 in the groove. The piston 15 is thus held on the rod between the dasher and the locking sleeve, so that the piston may be advanced to expel the contents. The dispensing port is fitted with a nozzle 16 having radial ports 40 which are closed in the extended position of the nozzle. The nozzle is retained in its extended position by a locking clip 45 which is removed to permit retraction of the nozzle to open the ports 40 for dispensing the contents.
