Title: Hydraulic pressure regulation
IPC: F15B11/02
Filed: 1953-09-14
Abstract: 773,785. Controlling hydraulic circuits. MONFORTS VON HOBE, C., [trading as MONFORTS, A. [Firm of]]. Sept. 14, 1953 [Sept. 13, 1952], No. 25344/53. Class 69 (2). An hydraulically-operated machine is regulated and/or controlled by the pressure difference between the main supply and a control circuit, the difference moving a valve or control member which may cut in or out an auxiliary pump, or operate a reversing valve, or cut off the supply if the main supply press is insufficient for the machine to complete its operation normally. A working piston A is moved in one direction by liquid from a pump 24 and in the other direction by liquid from a pump 20. A pump 10 supplies the control circuit L. If the pressure of the pump 20 is insufficient to overcome the pressure in the system L, a valve member 9 is moved to the right and cuts-off the supply from the pump 20 to the end 23 of the piston A. The valve 9 contains a non-return valve 26. When the pump 24 moves the piston A to its extreme left-hand position, the pressure on the end a of a control member 15, ,whose other end is subject to the pressure of the control circuit L, increases since the liquid supplied by the pump 24 has no outlet and moves the member 15 to the left so that the supply from the pump 20 through the valve 9 is connected to the right-hand end of a valve 5 which is moved to its left-hand position. The pump 24 is connected to discharge S via the valve 5. The system L is also connected to the lower end of a control member 21 whose upper end is subject to the pressure of the pump 20. An auxiliary pump 22 is provided and feeds into the supply from the pump 20 via a non- return valve 30 in the control member 21. If the pressure due to the pumps 20 and 22 is too great, the member 21 will move down and connect the pump 22 to discharge S.

Title: Improved roller-weighting apparatus for textile spinning machines
Inventor: WALSH FRED
IPC: D01H5/56
Filed: 1952-10-10
Abstract: 724,285. Roller weighting apparatus. T. M. M. (RESEARCH), Ltd. Oct. 12, 1953, [Oct. 10, 1952], No. 25433/52. Class 120 (2). Drafting apparatus of the type wherein the upper rollers are mounted in aligned pairs each upon a common arbor having its ends supported between pairs of cap-bars which are pivotally mounted at the rear of the drafting apparatus and which are separate from the cap bars supporting axially adjacent rollers is characterized in that each pair of upper rollers is loaded by the application of a downward force to a saddle resting upon the common arbor between them, said saddle being mounted for pivotal movement upon a pivot carried by the cap bars such that whilst said saddle is independently movable, it may also be raised with the rollers by raising the cap bar. In the embodiment shown, 10 indicates the roller beam and 11 the roller stand of a speed frame. There are four sets of drafting elements viz., rear rollers 12 and 13, intermediate rollers 14 and 15, an apron assembly 16, 17, 18 and roller 19 and front rollers 20 and 21. The upper rollers 12, 14, 16 and 20 and the tensor 18 of each drafting section are constituted by pairs of bosses carried upon arbors which are supported at the extremities between pairs of cap bars 22, 23 (not shown) which are pivotable on a shaft 24 extending along the rear of the apparatus. The position of the rollers 12, 14, 16 and the tensor 18, along the cap-bars is adjustable. Weighting is applied to the upper drafting elements through a saddle 27 which rests upon the arbors of the several roller pairs and is mounted for pivotal movement on a shaft 28 which spans the space between cap-bars 22 and 23 (not shown). This arrangement permits the saddle 27 to be lifted independently and also to be lifted with the cap-bars when the latter are raised. The saddle is, conveniently, made in two separate mating parts 271 and 272. The actual loading of the upper rollers is by the application of a weight 31 to the lower extremity of a stirrup 32 suspended from the saddle 27. The foot of the stirrup 32 is pivotally connected to a lever 34 which is pivoted to the roller beam 10 and the upper end of the stirrup is connected to the saddle 27 through a link 37 pivoted to a lever 38 one end of which is linked to a camlever 39 by a pivot pin 40 which is fixed to the saddle 27. If the weight lever 34 is raised the weight 31 is relieved by the engagement of the sprag 42 with the beam plate 44 and the stirrup 32 is pushed rearwardly, by the impingement of the face 341 against the abutment 321, so that it becomes disengaged from the link 37, and the entire assembly of the upper drafting elements may be raised into an inoperative position. If the front roller 20 only is to be removed the weight lever 34 is raised and the cam lever 39 is pivoted about the pin 40 so the lobe 391 of said lever bears against the saddle member 411 raising the fore end of the saddle 27 so that the roller 20 can be removed from the right-angled slots 26.

Title: Method of applying an adhesive material to a structural part
IPC: B05D1/30
Filed: 1973-05-29
Abstract: 1438540 Adhesive coated surfaces, coating apparatus CARRIER CORP 29 May 1973 [7 July 1972] 25457/73 Headings B2E and B2L Adhesive is applied to an object having a contoured surface by heating the surface to a predetermined temperature, conveying the object through a vertically falling curtain of adhesive at a speed to deposit a uniform coating of adhesive on the surface so that a portion of the liquid solvent of the adhesive vapourizes rapidly so that the adhesive will remain where initially deposited and depositing further adhesive on a preselected portion of the contoured surface which is disposed in a generally vertical plane by directing the additional adhesive in a generally diagonal path relative to the falling curtain. The contoured surface may be cleaned prior to the application of adhesive. The adhesive may be a mixture of a thermoset resin and neoprene in hexane or toluene. Pre-heating may be by infra red radiation. In the apparatus shown liquid adhesive is applied to the object 12 previously heated to 175‹F by passage through an infra red heater, by passing the object through curtain 19 supplied under pressure from header 22. Surplus adhesive is collected at sump 21 for recycling. The tubes 24 and 25 supply adhesive in a path diagonal to the curtain to the walls 14 and 15. The coated object then passes to a drying station. A further object to be bonded to the first may then be passed through the curtain of adhesive, partially dried and then bonded to the contoured surface. In a preferred embodiment an elastomeric bellows is bonded to the contoured surface.

Abstract: 692,366. Photo-mechanical printing surfaces. TOLAND, W. C., and HAMILTON, M. H. Oct. 19, 1950, No. 25476/50. Class 98 (ii). [Also in Group XVI] A lithographic printing plate A comprises a flexible base member 10, and a thin hydrophilic coating 12 of colloidal material bonded to the base member, the coating including at its exposed surface area relatively hard greasereceptive printing portions, and relatively yieldable water-receptive non-printing portions, a water-soluble organic dibasic acid in the form of a finely-divided solid being incorporated in the non-printing portions of the plate and being operative in the presence of mixture applied to the plate to repel adhesion of small amounts of greasy ink to the non-printing portions when the latter are contacted by an inking roller. The dibasic acid used may be oxalic acid, tartaric acid, succinic acid, fumaric acid, or malonic acid, and the hydrophilic coating comprises a colloid selected from the group comprising polyvinyl alcohol, gelatine, gum arabic, Irish moss, and water-soluble cellulose. A halftone plate made by the albumic process may be produced by coating the plate with albumin and ammonium bichromate and subsequently exposing the plate to actinic light passed through a photographic negative and intervening screen. The unexposed portions of the albumin are subsequently dissolved away, leaving the printing image 14.

Title: Improvements in valve gears for fluid pressure engines
IPC: F01L29/04
Filed: 1935-09-13
Abstract: 455,323. Engine valve-gear. CAPROTTI, A., 2, Via Pergolesi, Milan, Italy. Sept. 13, 1935, No. 25506. Convention date, Sept. 13, 1934. [Class 122 (ii)] Adjustable intermediate mechanism is arranged between a valve-gear normally adjustable for cut-off and reversal and a poppet valve operated thereby, so that at small cut-offs, the lift of the valve will be adequate. An oscillating cam is arranged between the valve and the combination lever of a Walschaert valve-gear. The lever oscillates the cam through a rod 3, and the cam reciprocates the valve through a pair of bell-cranks 4, 41, 8, 81, and an interposed block 10 which is adjusted from the reversing shaft in agreement with the block 19 in the link 20. The block 10 between the parallel sides 4<1>, 8 of the bell-cranks is connected through links and cranks to a crank 16 in the reversing-shaft. When the block 19 gives the latest cut-off, forward or reverse, the block 10 is moved towards the axis 5 and gives the minimum valve lift. When the block 19 is in the centre of the link 20, the block 10 is nearest the axis 7 and gives maximum valve opening. The Specification as open to inspection under Sect. 91 describes a rod 13 with a slot holding a spring adjacent the bell-crank 14. Safety-means to prevent misplacement of the block 10 are also described. A modification is described wherein the block 10 is adjusted by a spring-pressed lever engaging a V-shaped cam on the lever 14. This subject-matter does not appear in the Specification as accepted.

Title: Improved method of and apparatus for stabilising a sprung body, particularly applicable to motor vehicles
IPC: F16F9/26
Filed: 1936-09-22
Abstract: 483,641. Vehicle shock - absorbers. OYSTON, W. R. Sept. 22, 1936, Nos. 25781/36, 3886/37, and 12395/37. [Class 108 (iii)] A shock-absorber for vehicles, adapted to operate irrespective of the load when sudden vertical shocks are received and to be ineffective when the vehicle corners rapidly, comprises a control arm 4, Fig. 1, secured to a shaft 9 and abutting against a pair of plates 14, 14<1> which are integral with pistons 1, 2 working in cylinders 22, 23, and a valve rod 32 surrounded by a spring 42 and fixed to a slidable plate 31 which forms a datum abutment automatically adjusted according to the vehicle load. Oil or working fluid is supplied from a main chamber 28 fitted with a cover plate 29. Central openings in the pistons 1, 2 are closable by valves 43, 40 against which the spring 42 bears, and lateral passages 45, 39 therein by spring- pressed plate valves 44, 36. The valve rod 32 has an abutment 34 for engaging the valve 40 and also a telescopic extension piece 51 having lips 50, 52 which respectively engage a stem 48 of the valve 43 and a head 33 of the rod 32 proper. The plates 14, 14<1> are drawn towards each other and into engagement with the end of the arm 4 by a spring connection between projections 15, 15<1> on the plates. In operation, displacement of the pistons 1, 2 either to the right or left causes either the valve 40 or 43 to be displaced from its seating and permit a relatively free flow through the corresponding piston and lateral passage of the opposed piston; while during the return movement the flow takes place past the valve 40 or 43 against the resistance of the spring 42. The adjustable abutment 31 fits loosely in the cylinder 23 so as to permit a slow flow round its periphery of oil from an end chamber 35, such arrangement allowing the abutment to assume a normal position dependent upon the vehicle load. In order to stiffen the springing whilst cornering a rolling disc valve 53, Fig. 5, which has a central aperture 54 normally aligned with the seating 55 of the valve 43, is adapted under the action of centrifugal force to side up a slightly inclined track 56, disalign the openings 54, 55, and so render the shock-absorber rigid. In such circumstances, to prevent shocks being directly transmitted via the locked shockabsorber, a resilient connection may be interposed between the arm 4 and the vehicle axle. In a modification, Fig. 9 (not shown), corresponding actions are obtained in a shockabsorber having a cylinder only on one side of the arm 4.
