Patent GB-477818-A (GB)
Title: Apparatus for feeding fuel to internal combustion engines
IPC: F04C14/02
Filed: 1937-07-19
Abstract: 477,818. Rotary pumps. FAIRWEATHER, H. G. C. (Ehrich & Graetz Akt.- Ges., and Egersdorfer, F.) July 19, 1937, No. 19908. [Class 110 (ii)] The rotary pumps (preferably of gear-wheel type) have separate suction conduits but deliver liquid to a common conduit. Fig. 2 shows two gear pumps side by side in the same casing, having separate suction inlets 23, but one delivery pipe 16 leading to a carburetter or a fuel-injection pipe of an internal-combustion engine. Driving gears 2, 3 are keyed to a shaft 1 but may move axially, and gears 8, 9 may be free on a shaft 10, or keved to the shaft with axial freedom. The bushes 4 ... 6 and 11 ... 13 may also move axially, but are prevented from rotating. A screw 14 engages a slot in the bush 12. Excess liquid pumped is returned to the suction side by way of pipes 17, 21, 22 after forcing back a spring-pressed plunger 19. A passage 25 leads to the atmosphere or to the supply of compressed air for the engine. In a modification, the compressed air acts through a diaphragm which transmits the pressure to the plunger 19.
Patent GB-202625-A (GB)
Title: An improved method of and apparatus for the distillation or gasification of combustible materials
IPC: C10B1/10
Filed: 1923-08-03
Abstract: 202,625. Pehrson, A. H. Aug. 19, 1922, [Convention date]. Coking and carbonizing processes; retorts ; producers.-Combustible materials such as coal, shale peat or wood are treated to obtain oil, gas or smokeless fuel by being heated in rotary or oscillating horizontal or inclined retorts by contact with hot gases or by partial combustion with air or by electrical means, the retorts or furnaces each having in one or both of its end walls a central opening surrounded by an external neck extending laterally and being arranged in series so that each stage of the process is separate and the products withdrawn from each stage of fractional distillation. Coal is fed from a hopper 5, Fig. 1, to a rotary drying chamber 1 heated by a burner 6 and is charged by a worm feed 9 into a rotary retort 3 which is supplied with heated gas through tuyeres 12 provided with valves 13 to permit the tuyeres covered by the charge to be served with gas while the others are cut off. The distillates pass through a chamber 4 to an outlet 15 and the residue such as semi-coke is discharged by a worm 16. In Fig. 3, the retort which acts as a gas generator is fed through a relatively long neck 21 and air is admitted by tuyeres 28 after passing through a jacket 30. The charge is fed through the neck 21 and the gases and distillates escape through outlets 26 and 27 the ashes passing through a shorter neck 24 into a chamber 25. In other modifications, the charge is preheated by passage through a tube arranged coaxially inside the retort. The Specification as open to inspection under Sect. 91 (3) (a) describes also a retort provided with electrodes for heating the charge to obtain a product purified from sulphur by the addition of iron ore and from ash by two additions of a flux, and states that nitrogen may be recovered as ammonium chloride by addition of a chlorine compound to the charge; this subject-matter does not appear in the Specification as accepted. Specifications 178,443, [Class 39 (iii), Heating by electricity], and 184,810, [Class 51 (ii), Furnaces and kilns for applying &c.]. are referred to.

Patent GB-747421-A (GB)
Title: Improvements in and relating to rotary coin holder mechanisms for prepayment meters
Inventor: CHARLES JOHN ARTHUR
IPC: G07F15/02
Filed: 1953-07-20
Abstract: 747,421. Prepayment mechanism for gas and like meters. UNITED GAS INDUSTRIES, Ltd. July 19, 1954 [July 20, 1953], No. 20124/53. Class 27 A rotary coin holder mechanism, particularly for gas and electricity meters, has a lever 1 or 21 engaged by a coin at a point intermediate a fixed fulcrum and the point where the lever acts on a string-loaded striker 4 or 26 engageable with a quantity wheel 14 so that the movement of the lever is multiplied at the striker in order to distinguish more accurately between coins differing only slightly in size, for example, between a half-crown and a penny. As applied to the bi-coin mechanism of Specification 400,636, a shilling striker 30 is depressed by the coin engaging directly with a transverse part 29 and the half-crown striker 4 is operated indirectly by the lever 1 which is pivoted at 13 on the transverse part 3 of the striker. When a half-crown is inserted, the lever pivots about 13, the hump 12 assisting the coin into the pocket, until a pin 7 moving in a slot or opening 8 in the coin pocket wall engages an abutment or shoulder 10 and becomes the fixed fulcrum about which the lever pivots to depress the striker 4; as an alternative to the pin 7, the end of a slot in the striker may engage the abutment 10. Since the coin engages the lever between 7 and 13, the movement applied to the striker at 13 is multiplied. A spring 17 fitted between the coin pocket wall and a third pin 15 moving in a slot 16 returns the lever 1 to the extent permitted by a fourth pin 19 engaging the upper end of the opening 8 and, if the slot 16 is long enough, may serve to eject a small coin, as described in Specification 405,302. The pin 19 may co-operate with a pivoted latch 20, as described in Specification 436,733, when a small coin is inserted and, in a modification, the pin 19 may also perform the function of the pin 7 as a fixed fulcrum. In the modified construction of Figs. 6 and 8, a lever 21 pivoted at 22 is depressed by the coin to engage a lateral projection 25, or the end of a slot, on the striker 26. The movement of the lever away from the projection 25 may be limited by the engagement of a projection 27 with the coin pocket wall or the lever may be spring-loaded to maintain contact with the projection 25 but, in the latter construction, the spring 28 acting on the striker must be the stronger. To prevent a small coin from being inserted in the pocket, the end 33 of a spring-loaded lever 31 pivoted at 32 projects into the pocket until the lever 21, depressed by a coin of correct size, engages a cam surface 36 and withdraws the end 33.

Title: Apparatus for the detection of vibration in rotating machinery
IPC: G01H1/00
Filed: 1974-05-07
Abstract: 1471302 Vibration measurement  D J BIRCHALL 6 May 1975 [7 May 1974] 20159/74 Heading G1G Vibrations in rotating machinery are monitored by a system in which a signal representing the vibrations is compared with a first reference amplitude in a comparator, the comparator output is integrated, and the integration result is  compared with a further reference value in a second comparator, the latter giving an output signal indicating that the vibration signal has exceeded the first reference amplitude for a predetermined time. In the Fig. 2 embodiment the rectified input signal from a displacement or velocity sensitive vibration pick-up is compared at 1, 2 with reference levels to determine whether the measured vibration is excessive or below that expected, synonymous with a monitoring failure. If either condition lasts for greater than a pre-set period defined at 3 an alarm is actuated via a relay. The occurrence of either condition also closes switch 6 or 7, allowing feedback to the input of comparator 1 or 2 to latch the system in the alarm state even if the vibration level subsequently drops. Lamp 8 or 9 is lit, as appropriate. An inhibit device 5 prevents alarm actuation when either a calibration signal is applied to the comparator inputs or the rotating machinery is being started. In modifications the feedback paths through switches 6, 7 are replaced by a single path, Figs. 1 3 and 4 (not shown). Circuit details for one embodiment are given, (Fig. 4).

Title: Improvements in or relating to apparatus for drying webs of fabric
IPC: F26B13/04
Filed: 1934-07-10
Abstract: 422,168. Drying webs. WENZEL, E., 17, Wettinerstrasse, Aue, Erzgebirge, Germany. July 10, 1934, No. 20220. [Class 34 (i)] Apparatus for drying webs of fabric comprises a drying chamber into and through which the web is fed looped on the crossbars of a travelling chain, with a hinged shutter at the entrance, arranged to rest in turn on the fabric covering each entering cross-bar, and with mechanism whereby the entering cross-bars are rotated at such speed and in such direction that the surface velocity of the fabric on a cross-bar is substantially equal to the velocity with which the edge of the shutter resting on the fabric moves in relation to the axis of the bar. In the form shown, an endless chain formed of links 1 and cross-bars 2 moves in the direction x. The web of fabric 3 is fed in the direction j being laid in loops on the bars. Another endless chain 4 is driven through gearing 5, 6, 7 from the wheel 8 which drives the chain 1, so that chain 4 has a higher velocity than chain 1. A sprocket wheel 9 on each bar causes the bar to be rotated in the direction z, so that there is no relative motion between the fabric and the end of the shutter 10 while they are in contact. The gears 5, 6, 7 may be changed as is necessary.

Abstract: 730,722. Photographic product and process. INTERNATIONAL POLAROID CORPORATION. Aug. 14, 1952 [Jan. 8, 1952], No. 20453/52. Class 98 (2). The product comprises a multilayer structure including a photosensitive silver halide layer on a transparent support which is provided with a grid-like arrangement of minute optical elements, an image-receiving layer adapted to receive a transfer image from the photo-sensitive layer, and a silver halide developer. The product may have, also, a base providing a backing layer and a rupturable container holding a liquid processing agent. Additionally a fixer may be present. The minute optical elements may be lenticules whereby exposure may be effected through a conventional filter with two or more sections of different colour and the arrangement may be such that processing takes place on passing the product through a pair of pressure rollers in the absence of actinic light, whereafter the image-receiving layer may be stripped off and projected through a similar filter. Stereoscopic pairs of images may be made for observation through a viewing device, if desired with opposite plane polarizing for left and right eye vision. Alternatively the minute optical elements may be in the form of a colour screen so that, with a panchromatic silver halide layer, the colour screen principle of photography may be used. The process may be effected by permeating a liquid reagent containing a silver halide developer and a complexforming fixing agent into an exposed product of similar nature which does not itself contain developer and fixer. Specifications 684,592 and 703,231 are referred to.
