Filed: 1937-12-10
Abstract: 496,164. Projectile fuzes. PERRENOUD, G. Dec. 10, 1937, No. 34299. Convention date, Jan. 30. [Class 9 (i)] The regulating spring 2 of the clockwork mechanism of a projectile fuze is disposed axially of the projectile and is elastically supported in the axial direction, so that it is relieved from strain during the accelerating movement of the projectile. The spring shown is mounted in a protecting tube 16 carrying a spring-guiding member 17. One end of the tube is mounted in the socket 7 of a plate 8 which is recessed to receive a block 5 to which one end of the spring is secured. The spindle of balance 1 is journalled in the plate 8 and in a body part 4 of the projectile and is secured to the block 5. The spindle is allowed a certain freedom of axial movement and the block 5 also is free to move axially in its recess 6. The elastic supporting device for the spring comprises a star-shaped spring 18 the outer edges of which are riveted to a cap 15 on the tube 16 and the centre of which embraces a block 5<1> to which the forward end of the spring 2 is secured. The Specification as open to inspection under Sect. 91 describes modifications in which the shock-absorbing effect is obtained either by interposing a resilient joint between the spring 2 and block 5, or by providing resilient supporting means for the tube 16. This subject-matter does not appear in the Specification as accepted.

Abstract: 1,075,477. Distributing sand on roads. C. DOLZA and S. GROSSO. Aug. 25, 1964 [Aug. 27, 1963], No. 34819/64. Heading B8S. In distributing sand on the road a plurality of hoppers 1 are employed positioned upon a truck, the material being discharged through a valve 6 on to endless belt 18 which delivers the material into distributing hopper (21) (Fig. 1, not shown), the level of which is maintained constant. Valve 6, Fig. 2.-Each hopper 1 is divided into two compartments separated by a partition 4 and material is discharged therefrom by a frame 8 which rests on rubber blocks 12 and is reciprocated by a wheel (13) (Fig. 1, not shown) which is rotated by motor (14), the wheel being carried by lever (16) pivoted at (16a) so that the oscillation of the wheel (13) is transmitted as a horizontal longitudinal reciprocation of frame 8. Additionally a sliding frame 9 is provided which is carried by frame 8 and is displaced relative to frame 8 by handle 10 to control the amount of discharge through frame 8. The vibration also shakes the hoppers. Hopper 21 (Fig. 4, not shown).-The hopper is carried by frame (22) movably sprung at (23) and its movement is connected by levers (25) and (26) to wheel (13) so that when an excess of material is delivered into hopper (21), frame (22) is depressed, and the movement is transmitted to the levers (25) and (26) to reduce the speed of motor (14) which is thereby declutched and the feed of material to hopper (21) is stopped.

Title: Improvements relating to super-regenerative radio receivers of the type associated with transmitting means
IPC: G01S13/76
Filed: 1945-12-21
Abstract: 601,574. Radio signalling. FERRANTI, Ltd., TAYLOR, M. K., JONES, I. N. VAUGHAN-. Dec. 21, 1945, No. 34825. [Class 40 (v)] In a super-regenerative responder, interference with a nearby radar set is prevented by deriving a control voltage in response to a timing signal from the radar set and applying it to paralyse one or more valves in the responder for the effective reception period of the radar set. The Figure shows a known responder in which pulses of radio frequency energy from aerial coil 5 are amplified superregeneratively by valve 1, rectified by diode 17 and inverted in amplifier 23 to produce a positive pulse at the cathode of valve 31. The pulse is lengthened by network 35, 36 and applied to the responding oscillator 12 to raise grid 11 above cut-off and excite the aerial with a pulse of radio frequency energy. A positive pulse with trailing edge coinciding with the start of the main radar time base is applied at terminal P and the trailing edge is lengthened considerably by long time constant network 44 when diode 42 is cut off. The lengthened pulse is inverted in normally cut-off valve 51 and applied to grid 9 as a paralysing voltage for the duration of the time base sweep. If a common valve is employed for receiving and responding, the lengthened pulse from valve 51 is also applied to the grid of cathode follower 31 to neutralize the effect of the negative pulse reacting through circuit 35, 36, 37 when paralysis occurs. Resistor 40 acts as an R.F. filter in conjunction with the self capacity of diode 42 to protect the anode 41 from possible pick-up of response signals from the responder valve 12.
Patent GB-813911-A (GB)
Title: Wide band phase shifter
IPC: H03H11/16
Filed: 1955-12-05
Abstract: 813,911. Automatic phase-control systems. COLLINS RADIO CO. Dec. 5, 1955 [April 5, 1955], No. 34826/55. Class 38 (4). [Also in Group XL (b)]  A signal frequency is phase-shifted by a set angular value which is automatically rendered constant, independent of any variations of the input frequency or control system. As shown, the signal is applied through an amplifier to a resolver 47 producing a pre-set phase-shift determined by a dial 82 mechanically coupled to the rotor 53 of the resolver. The resolver output, from across the quadrature windings 54, 56, is then further phase shifted by a C.R. network 58, 57 cancelling the fixed 45 degree phase shift error produced by the resolver and applied through a buffer amplifier 61 to the output 62. The output phase is also applied through a buffer amplifier to a similar resolver 42, mechanically coupled with the dial 82 and signal resolver 47 but rotating the phase by an opposite amount equal to the pre-set phase shift, whose output is applied through an identical C.R. network 64, 63 to a network 30, vectorially adding it to an equal amplitude of the initially applied signal. The system operates to adjust the resistances 57, 63 to equal impedance with the reactances 58, 64, the C.R. networks then each advancing the output phase by 45 degrees, but change of input frequency will make this, say 45 degrees + #, giving a total phase change, including the fixed 45 degrees phase shift of each resolver, at the input of network 30 of 2#, and at its output of 90 degrees + #. This, after amplifying at 66 is applied to a phase detector 67 where it is compared with an amplified initial signal phase shifted through 90 degrees +# by another identical C.R. network 70, 69, connected across a transformer primary with earthed centre tap. The output of phase detector 67 then controls a motor 73 to adjust simultaneously resistors 57, 63, 69 to reduce the phase error #to zero, and, if this does not happen before the limits of resistance adjustment the motor 73 actuates one or other of limit switches 74, 75 to drive a motor 77 operating switches 59, 78, 79 to replace the capacitors 58, 64, 70 by others of value increased or decreased by a ratio 10. Finally the error #ia reduced to nil. The resolvers 47, 42 may each have a second set of stator windings 49 operated from amplifiers 52, and all amplifiers may have negative feed-back windings FB. Instead of resolvers other moving coil phase shifters or three coil selsyns may be employed. The network 30 may alternatively be a transformer primary winding differentially combining the two inputs, provided the signal and error rotors are coupled to rotate in the same direction. Moreover the phase detector 67, motor 73 and C.R. network 70, 69 may be replaced by a two-phase motor. The C.R. networks may be connected to dials indicating the frequency of the input.

A gas containing from 20 to 99% by volume CH 4  and substantially free of higher hydrocarbons is made by catalytically hydrocracking a petroleum product which has been desulphurized e.g. over a zinc molybdate catalyst, in the presence of a hydrogenation catalyst containing 1 to 50% of one or a combination of Fe 2 O 3 , NiO, CoO, Co 2 O 3 , ThO 2  and CuO. Reaction temperatures are kept below 700‹ C., to prevent cracking of the methane, e.g. by cooling the reactor, and where a plurality of catalyst beds in series are employed, heat exchangers may be provided between the beds. Reaction pressures of 20 to 50 bars are necessary. Refractory oxide catalyst supports (Al 2 O 3 , SiO 2 , MgO and metals of the 2nd Group of the Periodic Table) are employed. The process allows low starting temperatures (200‹ to 250‹ C.) to be used. Oxides of Group I metals may be included in the catalyst supports.

Title: Winterizing hardened soyabean oils
IPC: C11B7/00
Filed: 1960-10-12
Abstract: The subsequent separation of high melting glycerides from hydrogenated soyabean oil is facilitated by the addition of 0.05-0.5%, by weight of the oil, of a sucrose fatty acid ester which contains not more than 5 unesterified hydroxyl groups per sucrose molecule, and which contains at least one residue of a saturated fatty acid having 14-22 carbon atoms and at least one residue of a fatty acid having 2-6 carbon atoms, the fatty acids of 2-6 carbon atoms comprising 30-100% by weight of the fatty acids of 14-22 carbon atoms.  The oil, which has suitably been hydrogenated to an iodine value of 95-120, is usually heated to at least 140 DEG  F., but not enough to cause degradation, the sucrose ester added, and the mixture allowed to cool slowly over a period of days to 30-50 DEG  F. whereupon the glycerides which have separated may be rapidly filtered off.  In an example, the sucrose ester used was sucrose diacetate monopalmitate. Specification 962,813 is referred to.

Title: Improvements in or relating to lathes
IPC: B23Q5/34
Filed: 1946-11-27
Abstract: 660,781. Lathes. VICTORIA MACHINE TOOL CO., Ltd., FRYE, J., and SELBY, J. Dec. 29, 1947 [Nov. 27, 1946], No. 35174/46. Class 83 (iii). Feed mechanism for the apron and saddle unit of a lathe comprises a mechanical transmission through which the unit may be power fed longitudinally, means operated by the engagement of a trip element disposed on the unit with a stop to interrupt the feed transmission on the unit reaching a given limit and hand means by which the longitudinal feed may be continued for a small distance subsequent to the interruption of the transmission until the unit is brought to a positive stop on reaching a further limit. The longitudinal feed of the apron and saddle unit 3, Figs. 1 and 4, is effected from the usual feed shaft 7 and a sliding pinion 14 thereon to another pinion 15 on a parallel shaft 16 with. in the unit. This shaft carries a worm 17, engaging a large worm wheel 18 integral with which is a pinion 19 driving a relatively large toothed wheel 20. The latter revolves loosely on a transverse shaft 21 when the feed is disengaged, a pinion 8 being secured to the rear end of this shaft meshing with a rack 9 secured to the machine bed. A cap 22, Fig. 4, fits over the outer end of shaft 21 and serves through thrust bearings and against the pressure of springs 30, to bring a clutch face 24 on an intermediate splined sleeve 23 into engagement with a clutch face 25 provided on the wheel 20, thus inward movement of the cap-piece 22 engages the longitudinal feed. The wheel 20 is also connected through gearing and similar clutch members 41, 42, Fig. 6, to operate a screw controlling the transverse feed of the tool, in this case the clutch members are operated by a cap-piece 39. The latter is operated by a lever 48 provided with a camend and an anti-friction roller which rotates loosely about a shaft 27. A similar cam-piece and roller is secured to this shaft to operate the cap-piece 22 and longitudinal feed. The latter is tripped by an adjustable stop 58 on the bed contacting a plunger 56 on the apron unit the latter being in wedge connection with a cross-rod 60, Fig. 6, for rotating the shaft 27. After disconnection of the automatic feed the saddle may be moved by a hand wheel 62 until the head of the trip plunger engages a hardened shoulder 65 carried by the apron unit which acts as a limit stop. A lead screw 12 with a split-nut in the apron is provided for screwing and the control handle 51 therefore is interlocked with the shaft 27 so that screwcutting and automatic feed cannot be simultaneously engaged. A shaft 71, Fig. 1, runs the length of the machine and a lever 72, slidably keyed thereto is mounted in a gate at the side of the apron and controls the start, stop, and reverse of the driving motor for the machine.
