Title: Improvements in and relating to compositions comprising polyvinyl esters
IPC: C08K5/053
Filed: 1958-07-28
Abstract: Fusible compositions having a low viscosity in the molten state comprise polyvinyl acetate and/or polyvinyl propionate in admixture with octadecane-diol.  The diol, which can be obtained by the epoxylation of oleic acid followed by reduction, or by the energetic hydrogenation of castor oil, is homogenously incorporated into the polymer at between 100 DEG C. and 200 DEG C. in an amount up to 50% by weight of the polymer-diol mix.  The viscosity of the polymer is thereby sufficiently reduced to facilitate casting, or coating the polymer on to sheet materials such as paper, cardboard, or wood, at 120 DEG C.  The lower viscosity in the molten state also facilitates the incorporation of fillers, e.g. carbon black, kaolin, diatomaceous earth, and inorganic or organic pigments, e.g. iron oxide, titanium dioxide, zinc sulphide, barium sulphate, Berlin blue, chromium oxide, minium or phthalocyanine dyestuffs.  In examples melt viscosities at 120 DEG C. and other mechanical properties are compared for polyvinyl acetate alone, and separate mixtures thereof with 20% dioctyl phthalate and 20% octadecanediol.

Abstract: 654,284. Carburetting water gas. HUMPHREYS & GLASGOW, Ltd. Sept. 16,1948, No. 24355. [Classes 55(i) and 55(ii)] Gases from a water gas generator enter the carburetter which is of the " empty" type through a tangential inlet and pass upwardly or downwardly therethrough with a spinning motion, means being provided for varying the degree of spinning motion imparted to the gases to suit the blow phase, when rapid rotation is re- .quired to assist efficient heat transfer to the carburetter walls and the run, when the spinning must be reduced to avoid centrifugal deposition of oil. In one, form, Fig, 2, a movable vane c is disposed. in the carburetter a opposite the inlet b from a generator 1, and can be moved to deflect gases away from the walls to lessen their spinning motion. In Fig. 3, two inlets b and b<1> are provided, one being tangential and the other radial with respect to the carburetter. By manipulation of valves d and d<1> the degree of spinning motion can be varied. In Fig. 1 and Figs. 4 to 8 (not shown), other arrangements of inlet pipes and movable vanes for this purpose are shown. Specification 654,282 is referred to.

Title: Improvements in cation-exchange resins
Inventor: KRESSMAN THEODORE ROGER ERNEST
IPC: B01J39/18
Filed: 1954-08-20
Abstract: Cation exchange resins are made by introducing sulphonic acid groups into the benzene rings of a resin formed by reacting epichlorhydrin, a dihydric phenol and a phenol containing three or more hydroxy groups as a cross-linking agent.  Specified dihydric phenols include resorcinol, catechol, hydroquinone and dihydric phenols derived from acetone or formaldehyde and phenols, e.g. diphenylol propane.  The cross-linking agents specified are phloroglucinol, pyrocatechol and tetrahydric phenols derived from acetone and catechol, hydroquinone or resorcinol, e.g. bis-(2,4-dihydroxy phenyl)-dimethyl methane, whilst additional cross-linking agents, e.g. polyamines such as diethylene triamine, bifunctional compounds such as glyoxal, succinic acid, dichloromethyl ether, hexamethylene di-isocyanate and water soluble resins of the urea-, melamine- and phenol-formaldehyde types may be included.  Sulphonic acid groups can be introduced into the cross-linked resin by sulphuric acid or oleum.  In the example, a tetrahydric phenol prepared from resorcinol and acetone is mixed with diphenylol propane and epichlorhydrin and heated in caustic soda solution to solidification.  The solid is dried, broken up and sulphonated with sulphuric acid.

IPC: G03B3/10
Filed: 1967-05-25
Abstract: 1,196,771. Photo-electric distance measurement. EASTMAN KODAK CO. 25 May, 1967 [31 May, 1966 (2)], No. 24382/67. Heading H4D. [Also in Divisions G2-G3] A range finder especially for use in a photographic camera or projector has a pair of distance triangulating units one of which includes a light source emitting visible or non-visible radiation for projecting a beam of light along a first path towards an object to produce an illuminated area and the other of which includes light sensing means, for producing a signal when in alignment along a second path with the illuminated area. As shown, a camera objective lens 10 is movable with plate 13 for focusing an image on receiving surface 12, the lens 10 being moved as a function of object distance. A second lens 16 projects a beam of light along axis 20, such that the beam impinges the object at 37. A third lens 21 receives light along axis 25 and focuses on a photo-electric device 23, which may be a vacuum tube, a photoconductive or photovoltaic cell. The lens 21 and device 23 are carried by a plate which is rotated about a shaft 26 by a motor 33 through gearing 34, 35, 36 and connecting rod 28. Thus, the device 23 scans the axis 20 between points 38 and 37 to detect the illuminated area of the object. A cam 42 engaging arm 40 adjusts the position of plate 13 with respect to pins 14, thereby focusing lens 10. A solenoid 50 is energized, upon detection of the illuminated area, through a transducer 44 in circuit with device 23 to open a switch 54 to de-energize motor 33 and engage a tooth 55 with gear 35. A pointer 56 indicates the object distance on a scale 61. In another embodiment, Fig. 2 (not shown), a photo-cell (83) and a light source (81) are carried by plates (85) (86) actuated by a cam follower (97) engaging a cam (98). The range finder may be responsive to the depression of a camera shutter release (120), Fig. 3 (not shown), firstly to focus lens (121) automatically according to the distance between the camera and object and thereafter to actuate the shutter. Lens housing (125) is threaded in ring (126) and is rotatable by a gear (128) driven by an electric motor (133) or rotated manually. A rotatable mirror (141) performs the scanning in this case until gear (128) is arrested. In another embodiment, Fig. 4, a slit 215 is provided in a plate 216 mounted on a plate 204 carrying photo-cells, 212, 213 which scan axis 202 between points 217, 218. The scanning is terminated upon de-energization of motor 206 when the reflected light from source 200 passes through slit 215 on to the area 214 between the photo-cells 212, 213. A photovoltaic cell (235), Fig. 5 (not shown), energizes a movable coil (230) which rotates a needle (241) when the cell receives light through slit 236. The needle (241) engages the stepped surface of a plate (244) movable upwards by a lever 251. The needle (241) co-operates with a distance scale (245). The range finder may be used to adjust the projection lens of a projector as a function of the distance to the screen.

Title: Improvements in tens transfer mechanism for calculating machines
IPC: G06C15/38
Filed: 1924-10-16
Abstract: 223,583. Rudin, K. V. Oct. 20, 1923, [Convention date]. Transfer mechanism for cam-disc and pin-wheel machines comprises two (or more) transmission members, namely a two-armed transfer lever 12 interconnected with a shifting lever 8, between the transfer tooth 7 on the numeral wheel of the totalizer and the transfer-actuating pin 3 on the pin-wheel 1. Rigid with each numeral wheel 25 is a gear wheel 6 and a disc 27 carrying the transfer tooth 7. When a numeral wheel passes from 9 to 0 or from 0 to 9 the tooth 7 engages a shoulder 15 on the transfer lever 12 so that a pin 17 on the other arm of this transfer lever, normally resting in a slot 18 in the shifting lever 8. rides up past a nose 29 and into a second groove 19 of this shifting lever, thereby moving the latter to the left, Fig. 1, so that one of the two inclined surfaces 11 on this lever 8 moves the transferactuating pin 3 laterally of the pin-wheel into engagement with the intermediate wheel 5 of next higher denomination. After transfer the parts are restored by a restoring cam 21 co-acting with a nose on the transfer lever 12. The levers 8 are guided in a comb 22 carried in the movable carriage 10. As the pin 17 is further from the pivot 13 of the transfer lever 12 than the nose 15. and as the surfaces 11 are further from the pivot 9 of the shifting lever 8 than the notches 18, 19. the movement of the nose 15 is multiplied so that a very small movement of this nose suffices to effect transfer. Zeroizing-mechanism. - To prevent actuation of the transfer parts due to over-rotation of the numeral wheels during zeroizing, pins 23 on a shaft 24 are positioned behind the noses 15 at the appropriate moment. For this purpose the shaft 24 is driven from the resetting shaft 28. The Specification as open to inspection under Sect. 91 (3) (a) comprises also pickup pins on the shaft 28, which is connected to the shaft 24 by means of a crank arm on the latter and a notched cam disc on the shaft 28. This subject-matter does not appear in the Specification as accepted.

Abstract: 930,681. Lathe details. BIRFIELD ENGINEERING Ltd. July 30, 1959 [Aug. 1, 1958], No. 24809/58. Class 83 (3). A stop for a bar being fed through a collet in an automatic machine-tool, is movable axially and transversely, of the collet axis. The stop 2, Figs. 1, 2, is secured to a shaft 3, which is rotated to bring a spring-loaded pad 4 on the stop in line with the collet 1, and then swing away from the collet by a cam 10, which is synchronized with the mechanism for operating the collet, and actuates levers 5-7. The stop 2 is moved axially of the collet axis by a pneumatic cylinder 14. In operation, a bar 25, Fig. 3, is fed through the collet 1 by a second bar 26, until it compresses the spring 5 on the pad 4, and a workpiece is machined and parted off to the required length. This is repeated until the stub end of the bar reaches a certain point in the collet when a detecting means indicates that a new bar is required, and also actuates a control mechanism which supplies air to the pneumatic cylinder 14, Figs. 1, 2. The piston 16 turns a spindle 19, and levers 18, 21 counter-clockwise, thus moving the shaft 3 and stop 2 to the right, as seen in Figs. 1, 3. The stop 2 is rotated and ejects the stub end of the bar from the collet, and moves into line with the collet axis, thus locating the new bar 26 at a shorter feed position until the end of the bar is faced. Air is exhausted from cylinder 14 after a selected time due to a timing switch, and the stop is moved to its previous position. In a modification, stop 30, Figs. 7, 8, is moved from position A to the position B, thus indicating that a bar exists in collet 1. When the stop moves to position C, this indicates that there is no bar in the collet, and the operator is warned, or the machine is stopped. The stop is urged towards the collet by a spring 37 between a fixed stop 33 and an adjustable stop 34 on shaft 32. The rotational movement of the stop is as previously described. In a further modification, stop 41, Fig. 9, is rotated by a metal tape 43 wrapped around shaft 40, and secured to a fixed part 44 of the machine. As cross-slide 45 moves shaft 40 is rotated.

Class 75(1) In a liquid fuel burner of the vertical vaporizing pot type having an air inlet tube and a vaporizing trough, the air distributer consists of a casing surrounding the tube and having an outlet close to the surface of the fuel in the trough and further outlets into the main part of the burner, the tube communicating with the interior of the casing at a level to prevent ingress of fuel into the tube under all conditions of operation. In the form shown, the burner comprises a pot 6 having perforations 8, a vaporizing trough 5 and inlet tube 4, over which is mounted a casing 1 having perforations 7, 9, the lower edge of the casing being approximately level with the top of the trough 5. At pilot fire, the oil-level in the trough 5 is below the edge of the casing and air passes from the casing across the surface of the oil; at high-fire, the oil level is raised closing this outlet and air passes to the pot 6 by way of the perforations 7, 9. The casing 1 also serves to shield the trough 5 and fuel inlet 10 from direct heat from the combustion of the fuel. Specification 785,374 is referred to.

Title: Well Drilling Methods and Apparatus Employing Pressure Variations in a Drilling Fluid.
Inventor: GALLE EDWARD MILBURN
IPC: E21B21/00
Filed: 1967-05-30
Abstract: 1,195,862. Boring earth &c. HUGHES TOOL CO. 30 May, 1967, No. 24932/67 Heading E1F. In a method of rotary drilling the pressure of the drilling fluid surrounding the bit is subjected to cyclic fluctuations. The apparatus shown in Fig. 6 is located immediately above the bit and when in use the vibration generator A is touching the coupling device B. Part of the fluid passing to the bit nozzles is diverted through a port 163, a nozzle 167 and alternately into channels 185, 187. Part of the fluid entering the channel 187 enters a channel 195 to be discharged through a control nozzle 173 to divert the flow from the nozzle 167 into the channel 185. Some of the flow through the channel 185 passes through a channel 193 to be discharged through a control nozzle 171 to divert the flow from the nozzle 167 into the channel 187. The flow through the nozzle 167 therefore alternately passes through channels 191, 189. The flow from the channel 191 passes through a tube 217 and an aperture 219 to the cavity surrounding the 'bit, and the flow from the channel 189 passes through a tube 223 into an annular cavity 209 and through an aperture 225 to the cavity surround the, bit. Helmholtz resonators immediately above the generator prevent vibration in the fluid in the annulus about the drill string and in the fluid in the bore of the string to prevent loss of power. A shock absorber is embodied in the drill string above the apparatus. In a modified coupling device the tube 217 is replaced by a helically coiled tube discharging into the annular cavity which has a great number of outlets to the cavity surrounding the bit. In the modified apparatus shown in Fig. 10 a series of tubes 383 is mounted in the bore 381 leading fluid to the bit, each tube having an inlet 397 and diverting part of the fluid to discharge through holes 363 into the upwardly flowing fluid stream in the borehole. The diverted fluid spins and longitudinally vibrates a valve 359 to cause elastic vibrations in the spaces 357, 353 and the vibrations in the space 353 vibrate a member 367 which causes the cyclic fluctuations in the fluid surrounding the bit. In a further modified apparatus (Fig. 14 not shown) the bore leading fluid to the bit has a nozzle connected to feed-back channels, the arrangement being that cyclic pressure variations are given to fluid in an annular chamber surrounding the bore and these variations vibrate a ring (similar to the member 367 but mounted on the external wall of the chamber) which in turn causes the cyclic pressure variations in the fluid surrounding the bit.
