Title: Improvements in wrapping mechanism
Inventor: ROSE ALFRED GERMAN
IPC: B65B11/22
Filed: 1949-03-04
Abstract: 666,418. Wrapping - machines. ROSE BROS. (GAINSBOROUGH), Ltd. March 3, 1950. [March 4, 1949] No. 5954/49. Class 94(i). In wrapping- machines of the type in which blocks of plastic substances, e.g. ice-cream, are impaled on spiked members which carry them in succession into engagement with a succession of wrappers each of which is folded about one face and the two adjacent sides of a block in the form of a U, a pair of folding members are moved into engagement with the portions of the wrapper extending from the sides of the block to fold them over towards the face of the block pierced by the spiked members, and the latter are withdrawn after preliminary folding movement of the folding members so that the block is held by these members against any tendency to move under the withdrawing action of the spiked members. As shown, blocks 11 are impared on pairs of spiked members 12 mounted on radial arms 13 pivoted to a central rotatable supporting member 14. At the wrapping station, each arm is moved downwardly to engage a block with a wrapper 16 which has been fed on to a supporting plate 17 and to move the block and wrapper through an aperture 18 in the plate whereby the wrapper is folded around the block in the form of a U. The spiked members then deposit the block and wrapper on a platform 19, and during the latter part of this movement, a rod 21 and blade 22 are moved inwardly to fold the extending portions of the wrapper towards the upper face of the block. The rod 21 is carried by a lever 23, 24 actuated by a rod 28. The spiked members are then withdrawn from the block by an axial sliding movement on their supports 29 and the blade 22 continues its inward movement to complete the folding of the extending portion of the wrapper at that side of the block. During this movement, the rod 21 remains stationary and the portion of the wrapper engaged thereby is prevented from folding by the spiked members so that the two extending portions of the wrapper are caused to overlap. A reciprocating pusher then moves the block into a folding channel constituted by the platform 19, an upper guide plate 32 and a pair of side guides 33, this channel being provided with mechanism for forming the extending end portions of the wrapper into end closures. The initial movement of the block into the channel smoothes the portion of the wrapper initially folded by the red 21. Specification 648,152 is referred to.

Title: Improvements in snap action mechanisms
IPC: H01H5/18
Filed: 1943-04-14
Abstract: 567,614. Actuation of valves. BERRIDGE & CO., Ltd., I. L., MARTIN, C. S., KILBOURN, S. L., and COOKE, A. E. April 14, 1943, No. 5972. [Class 135] [Also in Group XXXVII] A snap-action mechanism for operating valves comprises two toggle-like compression members,'both being resiliently mounted end to end and pivotally supported with a stoplimiting lateral movement, the whole arranged to give snap movement towards or away from the stop by application of lateral pressure on one of the toggle members. Various examples are, described, in Fig. 1, on application of lateral pressure at a point P, compression is applied through a tension member 20 having a contact on its free extremity, operating between stops 17, 18. In modifications, a fulcrum beneath a mid-part of element 10, causes a lateral movement on both 10 and 20 to cause the pivot 13 to cross the tension member line with a snap. Specification 566,762 is referred to.

Title: Carburettor
IPC: F02M1/00
Filed: 1946-02-26
Abstract: 630,427. Valves actuated by auxiliary valves. DROUILLY, E. J. Feb. 26, 1946, No. 6011. Convention date, Oct. 19, 1945. [Class 135] [Also in Group XXVII] A throttle or regulating valve which controls a main air inlet is operated by and in one with, or secured to, a piston-like member slidable in a cylinder the outer part of which is connected with a space which is situated at one side of the throttle or regulating valve and in which prevails a depression due to the suction effect of the engine the outer part of the cylinder being also connected with atmospheric air by means of an air passageway the degree of opening of which depends upon the position of a member controlling the degree of opening of the carburetter fuel inlet. As shown, fuel entering at 29 and controlled by a valve 30 is mixed with air entering at 28 and the resulting mixture passes by way of an annular chamber 17 and holes 17a into a casing 2 connected to an engine induction pipe (not shown). Air also enters through holes 3a when a suction operated valve 4 is open. The valve 4 is connected to a piston 5 which is operated on by engine suction transmitted to a chamber between the piston and a cover 7. Orifices 11 connect the space around a spring 9 with the induction passage and the clearance between a rod 6 and the valve 4 connects the space around the spring to the space above the piston 5. The value of the suction in the chamber is varied by means of a valve 20 which controls a passage 23 connecting the chamber to atmosphere. The valve 20 is operated conjointly with the fuel valve 30. During idling the valve 20' is open but when an operating lever 25, connected to the usual footoperated pedal, controlling the fuel valve is moved away from the idling position, a cam surface 24 moves the valve 20 towards its seat so that the depression in the induction pipe may act behind the piston 5 and the piston moves upward and lifts the valve 4. If the operation of the lever 25 is continued in the same direction the end of the rod 19 of the valve 20 meets a part of the cam 24 which is but little inclined. The degree of lifting of the valve 4 depends upon the opening of the fuel inlet. The hand operated lever 34 can be operated independently and effects opening and closing of the fuel inlet 29 without changing adjustment predetermined by the lever 25. A pin 19a permits of varying the passage through a byepass arrangement comprising a radial hole 18, a passage 16, the annular chamber 17 and the orifice 17a.

Title: X-ray gauging method
IPC: G01B15/02
Filed: 1965-02-11
Abstract: 1,069,541. X-ray gauging apparatus. CORNING GLASS WORKS; Feb.11, 1965 [Feb.17, 1964], No.6034/65. Heading G1A. A cross-sectional area of an object is gauged by irradiating a reference object, of known dimensions and composition (this being the same as that of the object to be gauged), with a collimated X-ray beam, and detecting the unabsorbed portion of the beam to produce a first signal, irradiating the object to be gauged with a collimated X-ray beam and similarly obtaining a second signal, and comparing the first and second signals to give a difference representative of any difference in the cross-sectional areas of the two objects. The object to be gauged may be a rod, shaft or bar, or more particularly, glass tubing-being drawn during manufacture when the annular area of cross-section of the material of the tube is to be measured. In one arrangement Fig. 1, two beams from a source 11 are adjusted to be identical and each is collimated to be at least the width of the objects. The detectors 14, 16 ionization chambers, are connected to give a differential signal for indication on meter 17, which has previously been suitably calibrated, when the test object 13 and reference object 12 are in position. The reference object may be solid e. g. in the case of the gauging of glass tubing, a solid glass rod. The indicated signal represents the difference in the absorptions by the two objects. The meter is calibrated with measurements made on similar samples of known dimensions and of the same composition as the objects in values of cross-sectional area of the tube, inner diameter &c. The apparatus may be used in controlling the drawing rate of glass tubing, by using a reference object of a desired inner diameter, any deviation from this value in the test object being represented by a difference signal, from the detectors, which is used as the control signal. A modification of the apparatus Fig. 2 (not shown) involves a single radiation path, detector and meter. The meter is calibrated using a solid reference object e.g. a glass rod, of known dimensions and of the same material as objects to be gauged (glass tubes).

Title: Improvements in and relating to a wall construction
IPC: E04B2/28
Filed: 1948-02-27
Abstract: 648,918. Walls; blocks. WELLS, R. D. Feb. 27, 1948, No. 6086. Convention date, March 8, 1941. [Classes 20(iv) and 87(i)] A cavity wall is built from blocks having interengaging projections and recesses, the cavity being divided by vertical partitions formed of blocks which are keyed to one another and to the inner and outer walls, and are arranged to leave straight longitudinal passages for the accommodation of pipes, conduits &c. Blocks of various lengths are used in the wall, e.g., blocks 1, 2, 4, 6, 7 have one, two, four, six and seven projections respectively. As shown in Fig. 1, a course in the inner wall consisting of blocks 6 and alternate transversely arranged blocks 4, which do not reach the outer wall, is arranged opposite to a course in the outer wall which course consists of blocks 7. The latter course is surmounted by a course of blocks 4, 6 which is opposite to a course of blocks 7 in the inner wall, the oppositely directed blocks 4 being keyed together by the interengaging projections and recesses. Internal partition walls are bonded to the main cavity walls, but may be arranged without a cavity, or the cavity may be less wide than that in the main wall, so that the conduit passages are absent. In the wall shown in Fig. 4, the vertical partitions in the cavity of the wall are formed by resting blocks 4, which do not project into the inner and outer parts of the cavity wall, upon blocks 2 which are arranged transversely in alternate courses. The bearing surface at the top of the inner part of the cavity wall is increased to support a floor joist J, Fig. 6, by laying blocks 7 on the transverse blocks 4, the blocks 7 being supported at their middles and being spaced from one another. Another set of blocks 7 are laid on the spaced blocks 7 and are positioned by the interengaging projections and recesses and by an upper set of transverse blocks 4. The joist J, which is prefabricated, rests on the double row of blocks 7 thus provided, and is provided with cavities to key with the projections on the blocks 7. The joist is of the same height as a block, so .that it is incorporated in the wall construction. The wall construction of Fig. 1 may similarly be provided with a double row of blocks for supporting a floor joist, blocks 7 being rested on the blocks 4 projecting from the inner part of the wall, and being retained in position by abutting against neighbouring blocks 7 and by the blocks 4 projecting from the outer part of the cavity wall. On this row of blocks 7 is laid a course of blocks 4, 6 which, together with the course of blocks 4, 6 in the regular pattern of the wall, supports the floor joists. If it is required to support a roof truss, the outer part of the cavity wall is doubled instead of the inner part.
