Title: Improvements in means for central lubrication
IPC: F16N13/16
Filed: 1938-12-07
Abstract: 522,392. Force feed lubrication. LANGLEY, T. W., and TECALEMIT, Ltd. Dec. 7, 1938, No. 35720. [Class 12 (iii)] The oil pressure in the lubrication system of a motor car engine is used to operate a high pressure pump to supply lubricant to other parts such as the chassis or the upper parts of the engine cylinders. Fig. 1 shows a pump body 11, the cylinder 13 of which is connected by passages fitted with non - return valves to a lubricating oil reservoir and to the chassis bearings forming the top of a cylinder 3 in which slides a piston 4 secured by a member 8 to the piston 10 sliding in the cylinder 13. The cylinder 3 is connected by passages 30, 31 below and above the piston 4 to a cylindrical chamber 28 which slides a valve 29 formed with a central passage 38. The valve 29 is normally held by a spring 41 in contact with a plug 42 at the bottom of chamber. When the engine is started the engine lubricating oil is supplied under pressure through an inlet boss 37 on the chamber 28 to the space around a reduced portion of the valve 29 and passes through the port 30 to the space below the piston 4. The piston 4 is thereby raised against the resistance of a spring 15 and delivers the change of oil in the cylinder 13 to the chassis bearings, the oil above the piston 4 passing through the passages 31, 38 and a passage in the plug 42 to the engine sump. On the engine stopping the piston 4 is returned by the spring 15 to the bottom of the cylinder 3 and the cylinder 13 is recharged. An additional charge of oil may be supplied to the chassis bearings without stopping the engine by raising the valve 29 by a manually operated cable 47 connected by a hook 46 to the upper end of a rod 39 secured to the valve and then releasing it. A similar pump may be provided connected to the space below the piston 4 for supplying upper cylinder lubricant to the induction pipe at starting. A thermally operated valve prevents the delivery of the upper cylinder lubricant when the engine is hot.

Patent GB-806891-A (GB)
Title: Methods and apparatus for testing material
IPC: G01N21/89
Filed: 1955-12-14
Abstract: 806,891. Photo-electric testing. INTERNATIONAL BUSINESS MACHINES CORPORATION. Dec. 14, 1955 [Dec. 16, 1954], No. 35879/55. Class 40 (3). In testing material, such as card, for imperfections, a beam of light is scanned transversely over the surface thereof and the rate of travel of the beam is reduced in the vicinity of the edges of the material. In one embodiment card 17 is drawn by rollers through the testing device 10. This consists, for both upper and lower surfaces of the card, of a light source 11, energy from which is directed through one of the apertures in disc 12 to mirror 14 and thence reflected on to the surface of the card which is viewed by photo-cell 16. Rotation of the disc 12 causes the beam of light to scan across the card. In one extreme position it will be beyond the end of mirror 14 and will be reflected by blanking mirror 13 to a second photo-cell 15. The beam is then reflected by the mirror 14 to scan across the card from just outside the edge nearest mirror 13 to just outside the opposite edge; beyond this it passes from mirror 14 to screen 27. A fresh hole in disc 12 then comes into position and repeats the scan. Signals from cell 16 are amplified and fed through a gate to an output indicator or other device and the gate is normally open but is closed by light falling on cell 15. Preferably the output signal from cell 16 is differentiated. In order to prevent the output pulse which occurs when the beam passes over the edge of the card from masking pulses which may be derived from blemishes close to the card edge the rate of scan is, according to the invention, slowed down in the vicinity of the edges. For this purpose the outer ends of mirror 14 may be slightly curved as indicated at 25. The same result may also be obtained by the use of a suitably constructed prism in the optical system in place of mirror 14; or the mirror 14 may be planar and given a timed movement.

Title: Improvements in or relating to vulcanising machines for repairing motor vehicle tyres and other rubber articles
IPC: B29C35/00
Filed: 1938-12-14
Abstract: 522,543. Thermal switches. STEINER, L. Dec. 14, 1938, No. 36499. [Class 38 (v)] The circuit to the heating element 1 of a vulcanising machine is adapted to be completed by bridging a pair of contacts 3 by means of a pair of connected contacts 6 carried by an arm 7 pivoted at 7a to an arm 8 pivoted at 8a. A spring 13 biasses arm 8 upwards, and a second spring, not shown, biasses arm 7 upwards against a stop 14. To perform a vulcanising operation, a fusible rod 16 is inserted through a slot 15 in the casing so as to rest on a narrow slot 17 in arm 7. Depression of knob 12 moves arm 8 about its pivot and carries arm 7 with it until' sloping projection 22 passes through a slot in arm 7 to move rod 16 into a depression 23 where it engages under a fixed hook 25 in heat conducting relationship with element 1. When knob 12 is released, arm 8 rises, but arm 7 is held by rod 16 and hook 25 and pivots about 7a to close the circuit at 3, 6. Circuit is held closed until hook 25 is hot enough to melt rod 16 and release arm 7. Fragments of rod 16 fall through an opening 20 in the casing. Rod 16 is of the form shown in Fig. 5 and is passed through a similarly shaped slot 15 in the casing so as to prevent using an incorrect element. If a thinner piece of wire is used it falls through slot 17 and aperture 20. Specifications 449,376 and 519,944 are referred to.

The pneumatic moving means may be replaced by hydraulic or mechanical means, and the operating cycle of the machine may be made automatic and may be combined with automatic feed of work pieces to the work holder or the supply of work holders in succession, e.g. on a moving belt.
Patent GB-434317-A (GB)
Title: Improvements relating to the production of asphalt or bituminous compositions containing rubber
IPC: C08L95/00
Filed: 1934-12-21
Abstract: Finely divided rubber is suspended in a liquid which does not dissolve or only very slowly dissolves it, but which is completely miscible with bituminous material, and the suspension mixed with molten bituminous material before its character changes from a suspension to a solution.  The rubber powder may be obtained by spraying latex or latex concentrates for example as in Specifications 316,006, [Class 70], and 392,592, while the suspending medium may be one of the fluxing oils or agents of the asphalt industry. Suspensions containing for example 20 per cent by weight of rubber can be produced merely by agitation.  Powdered vulcanized rubber can be employed or vulcanization effected by adding vulcanizing agents to the suspending liquid and then heating, or the mixture of rubber, bitumen, and vulcanizing agents can be vulcanized.  Examples: (1) 11,25 parts by weight of rubber powder are stirred with 50 parts of heavy tar oil and the suspension added to 100 parts molten bitumen; (2) 10 parts of rubber powder suspended in 100 parts of flux oil are stirred into 100 parts molten bitumen.  Specification 216,602, [Class 22], also is referred to.

Title: Improvements in or relating to the extraction of sugar from sugar cane and apparatus therefor
IPC: C13B10/04
Filed: 1962-09-28
Abstract: In a continuous process for extracting sugar cane juices from sugar cane bagasse, the bagasse is conveyed through an extraction zone, sugar solutions of different concentration are delivered on to different sections of the surface of the bagasse within the extraction zone, the sugar solutions of different concentration being delivered to contiguous sections of the surface of that quantity of bagasse which at any one instant is present in the extraction zone in order of decreasing concentration with respect to the direction of movement of the bagasse through the extraction zone, the temperature of each of the sugar solutions is such as will render and/or maintain the tissues of the bagasse permeable and maintain the latter at a temperature not less than 65  DEG C. during its passage through the zone, the sugar solutions are allowed to percolate through the bagasse thereby making each of them more concentrated as a result of the extraction of sugar cane juices from the bagasse by diffusion and/or by lixivation and the more concentrated sugar solutions are collected, and the sugar solution delivered to any one of the sections of the surface of the bagasse is the solution collected as a result of the percolation through the bagasse of the next less concentrated sugar solution which was delivered to the adjoining section of the bagasse.  The temperature of each of the sugar solutions preferably is such that the temperature of the bagasse is maintained in the range of from 65-75  DEG C.  The pH of the sugar solutions should be between 6.2 and 6.5, and the retention time of the bagasse within the extraction zone from 20 to 30 minutes. Bagasse is fed in weighed quantities from a classifier into an extraction zone bounded by a metallic endless conveyer 7 moving over a fixed screen 9, longitudinal side walls 10, a clockwise-rotating (as viewed in the figure) adjustable height-limiting <PICT:1024428/C6-C7/1> drum 13 and an anti-clockwise rotating discharging drum 11.  The sugar solution delivered to any one of the spray distributers, excluding f and g for fresh and sweet water, respectively, is that solution collected as a result of the percolation through the bagasse of the next less concentrated sugar solution which was delivered to the adjoining section of the bagasse.  The saturation solution collected in tank 5e is passed through heaters 20 before delivery to the spray distributer e; the juice product is collected in tank 6f.  The delivery, temperature and pH of the sugar solutions are regulated from a control panel 19.  It is stated that the contents of any two of the collecting tanks 1a-6f may be mixed.  The Specification discloses a method of calculating the relationship between the dimensions of the apparatus and its capacity.
