Abstract: 446,825. Loading, unloading, and storing goods. BUDD, S. W., 5, Orford Gardens, Twickenham, Middlesex, HUGGETT, W. J., Holcote, Selborne Road, New Malden, Surrey, and MECHANICAL TRANSPORTERS, Ltd., Capel House, New Broad Street, London. Nov. 6, 1934, No. 31838. [Class 78 (iv)] A method of handling goods in a multistoried storehouse with a lift for serving the various floors, consisting in (a) loading the goods as received on to portable trays or containers resting on supports clear of the ground ; (b) running a transfer carriage underneath them and lifting them from the supports ; (c) trans. porting the lifted containers on the carriage into the storehouse lift ; (d) raising them to the required storage floor ; (e) running the carriage on this floor between fixed storage walls on to which the loaded tray is lowered for storage ; (f) re-loading on to a transfer carriage, when required for re-issue, and conveying to the delivery door of the storage floor ; and (g) transferring the tray by a crane direct to lorries from this point. Thus, loads such as rolls of news-print 13 may be picked up from a barge by the travelling crane 17 and stacked on the container 18 while it is resting on a support 20. A wheeled truck 21 is then run under the support and the jacks 22 operated to take the weight of the loadcontainer. The truck and container are then run into the portable lift 23, raised to the desired storage floor, traversed along the well to the desired point, and then run between storage racks which support the lowered container so that the truck can be removed. To re-issue, the truck is run beneath the stored container and again taken to the lift for transfer to a floor 26, Fig. 2, on which it is moved into the radius of action of a travelling-crane 27 which deposits the container on to a lorry 28. As modifications, the lift cage may move in a fixed well instead of being of the suspended portable type, and have a moving platform or floor or may be fitted with supports similar to 20 so that the original truck 21 is removed before ascent, and a second truck on the upper floor used to effect the movement to the storage racks. Both the trucks and the jacks may be electrically operated. Specification 429,375 is referred to.

Title: Improvements in and relating to processes and apparatus for the production of bituminous mixtures
IPC: C08L95/00
Filed: 1931-11-25
Abstract: A process for the production of bituminous mixtures consists in introducing steam directly into, and allowing it to condense within, a stationary receptacle, which is in free communication with atmosphere and contains aggregate subjected to the action of mechanical agitators, and introducing bituminous material in a non-emulsified form simultaneously, previously or subsequently. In the case when the aggregate is introduced first the steam treatment may be stopped upon introduction of bituminous material or it may be continued thereafter.  If desired, the steam may be introduced through an injector device for introducing the bituminous material into the mixer.  A colloidal substance such as gelatine may be supplied to the receptacle in addition to the bituminous material. The invention may also be applied to the treatment of previously formed bituminous substances composed of aggregate and bituminous material or naturally occurring mineral substances impregnated with bitumen, with or without the addition of further bituminous material.

Title: Improvements in or relating to vehicle hydro-pneumatic suspension units
Inventor: WORDSWORTH JACK
IPC: F16F9/096
Filed: 1958-10-14
Abstract: 861,003. Hydro - pneumatic suspensions. ARMSTRONG PATENTS CO. Ltd. Sept. 25, 1959 [Oct. 14, 1958], No. 32674/58. Classes 108(2) and 108(3). A hydro-pneumatic suspension unit of the type wherein a load applied to a confined volume of oil is balanced by a gaseous cushion acting as a spring has a double acting hydraulic pump operated directly from a spindle responsive to suspension movements to supply the said confined volume through valve controlled passages. A spindle 1 connected to the vehicle displaces a piston 13 in cylinder 12 through a connecting rod 14 in responseto vehicle movements, oil being displaced through damping holes in the end of the cylinder from and into a confined space 18 within a flexible diaphragm 17. The hydraulic pressure on the diaphragm is balanced by air or other gas compressed within chamber 19 between the diaphragm 17 and doved cap 15. Vehicle height is maintained constant by the actions of the pump and a relief valve A. The pump is driven by an eccentric spigot 2 on the end .of the spindle 1 and a drive shoe 3 mounted in the relieved central portion of the pump plunger B. In response to vehicle movements the plunger B draws oil from the reservoir chamber 11 through the relieved central portion of the plunger past non-return valves into chamber 5 or 6 from which it is pumped through non- qeturn valves C and delivery passages D into the space 18. One of the passages D contains a portion E between the space 18 and a relief valve A comprising a removable capsule 23, with a transverse passage 27 joining passages D and E, containing a valve seat 25 and ball valve 7 on the other side of which is a reduced portion of a valve operating member 26. As the pressure in space 18 increases the spindle 1 is rotated by the piston until a cam plate 9 and the plunger 26 bearing on it raise the ball valve 7 from its seat allowing oil to flow from the space 18 through passage E and groove 8 in the plunger 26 back into the reservoir 11.

Title: Improvements in or relating to circuit arrangements for electrical measurements and examination
IPC: G01R23/00
Filed: 1946-11-04
Abstract: 620,727. Wave analysers. MARCONI INSTRUMENTS, Ltd., and BROCKELSBY, C. F. Nov. 4, 1946, No. 32735. [Class 37] In a wave analyser in which a wave input to be examined is applied to a mixer which also receives oscillations from a variably-tunable local oscillator so as to produce an intermediate frequency which is passed to a voltage measuring circuit, the wave energy from the input or wave energy derived therefrom is applied to the local oscillator to lock it in step. The wave input to be examined is applied to input terminals 1, 2 and thence through a variable attenuator network 3 and buffer amplifier 4 to constitute one input to a mixer circuit 5. The wave input is also applied to an amplifier 6 followed by an amplitude limiter 7 whose limited output is utilized as the locking input to a variably-tunable local oscillator 8, which may have a range from 20 to 20,000 cycles per second. The tuning control is shown at 8a. The output from the oscillator 8 is applied as the second input to the mixer 5, the intermediate frequency output from which is fed to a voltage measuring arrangement 9. Preferably part of the locally-generated input for the mixer is taken off at 10 to an automatic level control circuit 11 so as to control the amplitude of the locally generated oscillations and maintain this input to the mixer constant. The local oscillations are preferably adjusted to a frequency such as will produce zero intermediate frequency output from the mixer, in which case the voltmeter 9 is of the D.C. type. The local oscillator is brought into and held in synchronism with the original input frequency. Thereafter any alteration in the tuning which leaves the frequency locked alters only the phase difference between the inputs to the mixer so that this can be adjusted to zero. An additional phase shifting network may be included in one of the mixer input channels to facilitate adjustment of the phase difference to zero. The amplitude limiter 7 may be arranged to produce an output which is rich in harmonics of the original input frequency and the oscillator 8 may be adapted to be locked in any desired one of these harmonics, so that each harmonic may be measured in turn. By including a number of mixers each feeding its own voltage measuring circuit, a whole harmonic range may be indicated at once.
