Title: Improvements in lifts
IPC: B66B17/12
Filed: 1920-02-27
Abstract: 139,516. Calvo, J. M. B. Feb. 27, 1919, [Convention date]. Balancing.-In a lift means are provided for automatically removing from and replacing in each cage a weight equal to the load carried after the load has been put into or taken out of the cage. When a single counterweighted cage is used, the cage f, Fig. 1, is suspended from a float e placed in a tank d which rests on a platform b, suspended from the hoisting rope c. When the cage is empty, the liquid in the tank is at the level of the discharge pipe g, but, when a load is put on at any platform B, a quantity of liquid equal in weight to the load will be discharged into the tank h. When this load is discharged at a platform A, Fig. 3, the float e will rise and the level of the liquid in the tank d will fall. The tank is then connected to the outlet i of the tank h at this floor, and liquid is allowed to flow until the tank d is again filled to the level of its outlet g. Before taking on a load at this floor, the cage is raised to the platform B, so that the liquid discharged will flow into the tank h. In a two-cage lift system, Fig. 6, the tank h floats in a tank h<1>, and the tank d communicates with the tank h when the cage is at rest by a non-emptying syphon m. When the cage is moving, the syphon m is held in raised position clear of the liquid by an electro-magnet which is energized only during the travel of the cage. A small float keeps the lift circuit open until the liquid in the tanks d, h is at the same level.
Patent GB-572898-A (GB)
Title: Improvements in and relating to the production of amines
Filed: 1943-04-14
Abstract: A process for the preparation of alkylamines comprises reacting one or more aliphatic monohydric alcohols containing not more than two carbon atoms with ammonia in the gaseous phase and in the presence of a dehydrating catalyst, separating the desired amine or amines from the reaction products, treating at least a part of the residual reaction products with an aqueous medium to dissolve the undesired amine or amines and vaporizing the aqueous solution thus obtained and returning it to the reaction step.  The whole of the reaction products may be treated for the recovery of the amines, and unreacted ammonia and alcohol, but it is preferred to cool the reaction products, whereby an aqueous condensate is obtained containing the amines and unreacted ammonia and alcohol, whilst the normally gaseous side reaction products such as carbon monoxide, hydrogen and olefines corresponding to the alcohol used are allowed to escape from the system.  The amines and unreacted ammonia and alcohol are then driven as vapours from the aqueous solution, and the desired amine or amines separated by known methods.  The residue from the vapours is then treated with water for the recovery of the undesired amines, ammonia and alcohol and the resulting aqueous solution is vaporized and returned to the reaction step.  In further features of the invention, the water remaining after driving off the amines, unreacted ammonia and alcohol may be used for the recovery of traces of amines, ammonia, and alcohol from the normally gaseous side reaction products before they leave the system, and the solution so obtained may be used as the above-mentioned aqueous medium for treating the residue remaining after separation of the desired amines. Alternatively, the water remaining after the amines, unreacted ammonia and alcohol have been driven off, may be used for treating the residue left after separating the desired amines, together with the normally gaseous constituents separated from the reaction products.  The vaporized aqueous solution to be returned to the reaction step may be returned by itself as with the alcohol and/or ammonia to be used in the reaction.  This alcohol may also be added to the water to be used in treating the residual vapours and the ammonia added to the resulting liquors.  It is necessary to remove continuously or from time to time a quantity of water about equivalent to that produced in the reaction.  Examples describe the preparation and recovery of methylamines and ethylamines prepared from the alcohols and ammonia, employing the basic aluminium phosphate catalyst described in Specification 528,987.

Title: Improvements relating to strapping tools
Inventor: RANSOM FRANK STEEPLES
IPC: B65B13/28
Filed: 1962-02-17
Abstract: 951,352. Twisting wires together. POWER STRAPPING SYSTEMS Ltd. Jan. 17, 1963 [Feb. 17, 1962], No. 6213/62. Heading B3E. A power-operated strapping tool for securing a flat wire around a package by twisting the two ends together in the radial slot of a twister pinion is characterized in that the drive to the twister pinion includes a driving gear-wheel having a blank portion from which teeth are absent and in that there is provided a separate control gear which is driven from the twister pinion during the twisting operation and which acts upon control spring means to stress such spring means during the twisting operation whereby, when the drive to the twister pinion is interrupted due to the blank portion on the driving gear, the spring means acts to reverse the direction of rotation of the control gear and thereby cause a reverse rotation of the twister pinion. A twister pinion 18 is rotated by a gear 13 driven from a drive shaft 17 of a power tool, e.g. an air turbine. The pinion 18 in turn rotates a control gear 14 loosely mounted on a boss 19 of the gear 13. The gear 14 has secured to its face a disc 22, formed with two flats 23, which engages a bridge-piece 30 urged towards the disc 22 by springs 31. The control gear 14 has fewer teeth than the toothed part of the gear 13 so that it will complete one revolution and a further partial rotation before the gear 13 reaches a point at which a blank, untoothed, portion thereon comes into register with the twister pinion and drive thereto ceases. This further rotation causes the bridge member 30 to be tilted out against the springs 31 by the control disc 22 so that when the twister pinion drive ceases the springs 31 cause the disc 22 to turn back until a cam member 33 on the disc 22 engages the end 35 of a spring-mounted stop arm 34 whereupon further rotation is prevented, both flats 23 on the disc 22 then engaging the bridge-piece 30. This reverse rotation of the disc 22 causes, through the gear 14, the pinion 18 to turn back until its slot is horizontal. In a modification, Fig. 5A, springs 46 are secured at one end to arms 45 on a block 44 on the shaft 12 driven by the gear 13 and at their other ends to pins 42 on a circular control disc 40 secured to the gear 14. As the gear 14 turns slightly faster than the gear 13, the springs 46 are tensioned and when the drive to the twister pinion 18 ceases the springs 46 turn the disc 40 back until a notch 41 thereon engages a spring mounted stop arm 48. The pinion 18 is thus stopped with its slot horizontal.

Title: Arrangements for demodulating phase or frequency-modulated carrier waves
IPC: H03D3/20
Filed: 1951-03-16
Abstract: 689,355. Frequency and phase modulation; pulse modulation. STANDARD TELEPHONES & CABLES, Ltd. March 16, 1951 [March 18, 1950], No. 6369/51. Class 40 (v). In order to de-modulate frequency or phase modulated waves, they are first converted into duration-modulated pulses of constant amplitude by applying them to one control grid of a valve, to the other control grid of which are applied time-delayed pulses derived from the valve anode, the grids being so biased that the valve is blocked when either grid is driven negative. The duration-modulated pulses are averaged or smoothed to produce the demodulated signal. The incoming wave is applied at 4, 5, Fig. 1, to the suppressor grid of the pentode valve 1, the positive half-wave releasing anode current and causing a negativegoing pulse to appear at the anode. This pulse is fed through a delay network 2 to the inner control grid, and its leading edge blocks the valve and cuts short the anode pulse. The voltage curve A of Fig. 2, indicates the clipped incoming wave of period T applied to the suppressor grid, B shows the resulting anode voltage pulses, and C the pulses applied to the inner grid after a delay to. The average anode current is proportional to to/T and thus varies with the frequency of the incoming wave. The de-modulated signal may therefore be obtained at terminal 7 by connecting the anode thereto through a low-pass filter 8. Instead of deriving the delayed pulse from the anode of the pentode valve 1, it may be derived from the anode of a separate triode, which has its grid connected to the suppressor grid of the valve 1, Fig. 8 (not shown). Fig. 2 illustrates the case in which to lies between T/4 and T/2. If to is less than T/4 each cycle of the wave produces two or more pulses. This case and others in which to is greater than T are illustrated by further diagrams, Figs. 3 to 7 (not shown).
