Filed: 1963-02-15
Abstract: 984,178. Tyre removing apparatus. MANN EGERTON & CO. Ltd. Feb. 14, 1964 [Feb. 15, 1963], No. 6316/63. Heading B7C. A tyre remover comprises an axially reciprocable pillar, a wheel support 10 arranged to locate and retain a wheel in a stationary position concentric with the pillar, and a carrier 14 rotatably supported by the pillar and provided with radially extending arms 18, each of which pivotally mounts a tyre removing finger 19 having its free end inturned towards the pillar to engage the bead region of a tyre 21, together with pneumatic or hydraulic operating means to effect axial reciprocation of the pillar relative to the wheel support 10. The pillar comprises a rod 1 and an extension member 3 which is coupled to the rod by a bayonet joint. The rod 1 carries two pistons 8, 9 which reciprocate vertically within a, cylinder 2 which is secured to the floor. The cylinder 2 is both double-acting and singleacting so that the flow of fluid to the cylinder urges the fingers 19, with maximum force, to their tyre-releasing positions, and, with lighter force, to return to their initial positions. The carrier 14 is located on the pillar by pins selectably inserted through axially spaced holes 16 in the extension member 3. Each finger 19 is prevented from swinging away from the pillar beyond its vertical position.

Filed: 1956-02-29
Abstract: 799,363. Regulating switches. GENERAL ELECTRIC CO., Ltd. Feb. 28, 1957 [Feb. 29, 1956], No. 6345/56. Class 38 (5). In a transformer on-load tap-changing arrangement having diverter circuits, the two diverter switches per phase are operated to maintain continuity during tap-changing by associated pairs of radial arms carried by an oscillating shaft. Fig. 2 shows one diverter switch 18, 19 and Fig. 3, the other diverter switch 20, 21. The switches are actuated by links 12, 14 and 13, 16 and bell-cranks 15 and 17 respectively, the links 12 and 13 being loosely mounted on a common shaft 1. Projections 8, 9 on generally radial arms 4, 5 of a bifurcated member 2 rigidly mounted on the shaft 1 abut the link 12 and projections 10, 11 on similar arms 6, 7 of a bifurcated member 3 also rigidly mounted on the shaft abut the link 13. When the shaft 1 is oscillated in a clockwise direction, the projection 8 first abuts the link 12 and closes the switch 18, 19 and then the projection 10 abuts the link 13 and opens the switch 20, 21. Oscillation of the shaft in the reverse direction causes projection 11 to abut the link 13 and close the switch 20, 21 and then causes projection 9 to abut the link 12 and open the switch 18, 19. The switches are latched in the closed position by recesses 24, 25 in members 22, 23 which fit over the pivot pins 26, 27 respectively. The latches are disengaged prior to the opening of the appropriate switch by projections 28, 29 on the members 23 which co-operate with camsurfaces on the members 22, 23 respectively. The shaft 1 is oscillated by the mechanism described in Specification 709,227.

Filed: 1916-05-03
Abstract: 124,837. Daniels, L. A., and Gardiner, C. A. P. May 3, 1916. Projectiles; projectile fuses.-Relates to grenades adapted to be exploded by percussion, and consists in the combination of a firing-pin, a shock-released catch normally held between a shoulder on the pin and the grenade casing or a plug through which the pin slides, a safetypin normally pressing the catch in the retaining position, and means for holding and releasing the safety-pin. In the grenade shown, a spring-controlled firing-pin 8 is retained in the cocked position by a catch 16 consisting of a resilient metal strip, one end 18 of which is weighted, Fig. 4. The catch 16 is normally held in position by a radial pin 20, which a spring 22 tends to throw outwardly. A tape 23 having a weight 25 at its outer end is bound round the neck of the grenade so as to hold the pin 20 in place, and is adapted to be secured by a split-pin 30 or the equivalent. When the grenade is discharged, after the weighted end of the tape has been freed, the tape unwinds and releases the safety-pin 20 during flight. The arrangement is such that the tape does not unwind sufficiently to arm the fuse if the grenade is accidentally dropped. A rod 33 may be screwed into the base plug 2 to enable the grenade to be fired from a rifle.

Title: Improvements in or relating to dehazing petroleum oils
Inventor: SHOEMAKER BERNARD HARVEY
IPC: C10G73/24
Filed: 1951-03-22
Abstract: A substantially wax-free petroleum oil which develops a haze on cooling to a low temperature is refined by contacting the oil with urea and separating the resulting urea reaction product from the oil. A haze-free oil is thus obtained.  The urea may be activated with a solvent such as water, methanol, ethanol and acetone.  The oil may be filtered through a bed of urea or agitated with urea in a mixer and afterwards separated by settling, centrifuging or filtering.  A hydrocarbon solvent may be added to the oil, such as an aromatic or naphthenic solvent for example toluene or cyclohexane, a branched chain paraffin such as isooctane, or a hydrocarbon having less than 6 carbon atoms such as propane, pentane or butane.  If necessary, the oil is first dewaxed by dilution with a solvent such as those described above, chilling and separating the wax.  The urea may be regenerated by dissolving in a solvent or melting and separating from the haze-forming substance.

Title: Magnetic amplifier circuit
Inventor: ECKERT JOHN PRESPER
IPC: H03K19/16
Filed: 1957-03-04
Abstract: 845,204. Circuits employing non-linear magnetic elements. SPERRY RAND CORPORATION. March 4, 1957, No. 7042/57. Class 40 (9). A first winding on a magnetic core having a substantially rectangular hysteresis loop is pulsed successively during spaced intervals between which the core is set to saturation in one direction or the other by means of one or more other windings on the core so that the successively-applied pulses are selectively caused to encounter a high or a low impedance in the first winding. In Fig. 2 the winding 21 is energized by the power pulses shown in Fig. 3, rectifier D1 gating the positive half-cycles. A control-winding 22 has each end clamped to earth by sources of potential - V and rectifiers D5 and D6. Clock pulses occurring during the negative half-cycles of the power pulses are applied to one end of the control winding 22 over an inhibition gate 27 which suppresses a clock-pulse whenever an input pulse is applied to the other end of the control winding. In the absence of an input pulse the clock-pulse holds the core saturated in a direction such that the succeeding power pulse meets a high impedance and what current passes through the coil 21 is suppressed by the equal and opposite current from a source - V through a diode D2 tied to the output lead 24. When an input pulse is received the core is switched to saturation in the opposite direction such that the succeeding power pulse meets a low impedance in winding 21 and a substantial output appears on lead D. The voltage induced in winding 21 when the core is switched by the input pulse is backed off by the negative portion of the power pulse waveform. In the above arrangement an output is produced subsequent to an input. If the sense of winding 22 is reversed an output is produced for each power pulse except those preceded by an input pulse. In Fig. 4 an alternative arrangement comprises a winding 41 energized at A by the power pulses shown in Fig. 5. To a terminal D of an input winding 42 a negative bias is normally applied to hold the core saturated so that winding 41 does not switch the core when energized by a positive power pulse. The negative bias is switched to positive to constitute an input signal which over rectifier D9 energizes a winding 43 to switch the core so that the subsequent positive power pulse switches the core back again and in so doing induces an output voltage in a winding 44 which over rectifier D10 energizes a load RL. When the core is switched by the input pulse the negative excursion of the power pulse waveform decouples the winding 41 while blocking pulses applied to terminal C decouple the output winding 44.
