Filed: 1951-04-13
Abstract: 702,155. Wrapping- machines. FORGROVE MACHINERY CO., Ltd.. and BROOK. L. April 2, 1952 [April 13, 1951], No. 8653/51. Class 94 (1) [Also in Group XXIV]  In a wrapping-machine comprising driving and driven members mounted to rock about a common axis a spring disposed between the two members serves to impart movement in one direction from one to the other and is so mounted as to be capable, in the event of obstruction to movement, of the driven member, of changing its line of action to reduce the mechanical advantage of the arrangement, an abutment being provided for positively imparting return movement from the driving to the driven member. As shown, 'applied to the lifting plunger 25 of the machine described in Specification 702,154, the bar 26 carrying the plunger is supported by links, 31 and 32 and is periodically lifted by a cam 33 which operates through a follower 36 on an arm 35 secured to the pivot shaft 34 of the link 31, a bell-crank 37 also secured to the shaft, and a spring 38 interposed between the bellcrank and link. The spring embraces a rod 40 carrying fixed and slidable trunnion blocks 42 and 41, the trunnions 43 and 45 of which engage slots in the bell-crank and link. The trunnions 45 arenearer the axis of the shaft 34 than the trunnions 43, so that if the spring yields due to an obstruction to the movement of the plunger the continued movement of the bell-crank causes the rod 40 to pivot about the trunnions 45, whereby the line of action of the spring becomes progressively more nearly radial to the shaft 34. The lowering of the plunger is effected by an adjustable screw 39 on the bell-crank which engages the upper surface of the link 31.

Patent GB-482783-A (GB)
Title: Improvements in and relating to processes for the manufacture of diesel fuels
IPC: C10L1/02
Filed: 1937-03-25
Abstract: An oil poor in hydrogen manufactured synthetically by hydrogenation of a distillable carbon-containing material such as mineral coal, brown coal, coal extract, primary bitumen or the like is mixed with an oil rich in hydrogen, manufactured by synthesis from carbon monoxide and hydrogen or by the hydrogenation of coal or the like, to form a Diesel oil.  The fuel can be further cheapened by addition of a coal extract or a primary bitumen or of high-boiling fractions obtained preferably by vacuum distillation from such materials or from hydrogenation oil.  Such extracts or bitumen are preferably dissolved in the oil poor in hydrogen, to which is then added an amount of oil rich in hydrogen greater than is required in the final product.  Any flocculation occurring is then removed by heating, and filtering or centrifuging, after which the excess of oil rich in hydrogen is distilled off to leave a stable Diesel oil.  In an example, a hydrogenation oil produced by further hydrogenation of primary bitumen, having a hydrogen content of 8,5 per cent, is heated with 25 per cent of bitumen.  To 100 parts of the solution are added 25 parts of a middle oil rich in hydrogen, obtained from destructive hydrogenation or by carbon monoxide and hydrogen synthesis.  About 8 per cent of a pasty asphaltic precipitate is centrifuged off and the remaining solution is distilled to drive off 12 per cent of the oil rich in hydrogen.

Addition to 383,855. [Class 17 (i).] Pounding-up.-The machine described in the parent Specification is modified by the provision of means ensuring that the side beater contacts with the work before the sole face beater, and an improved mechanism for moving the work support. A second cam track governs the movement of the tool towards and away from the work at the beginning and end of the operation. The work support is slidable on a guide simultaneously tilted about an axis, the length of slide and maximum angle of tilt being independently adjustable. The sole face beater 113 is of the drum type driven by gearing from a shaft 22 also driving an eccentric strap reciprocating a block 118 driving the side hammer 115. This mechanism is carried on a frame 100 pivoted about the shaft 22 and urged clockwise by a spring 107 adjustable in strength by a handwheel 105. An adjustable stop 44 carried by the frame also contacts with the end of an arm 101 pivoted at 120 to a member supporting the tools and pivoted at 2 as described in the original Specification. The arm 101 extends from a member slotted to engage a block on a member oscillated by an arm 123 having a roll engaging a cam track 125, this track being so shaped that the beater 113 is supported away from the work until after the side beater 115 has engaged it. The shoe 68 is supported by toe and heel struts from a member 148 slidable on a member 127 pivoted at 126 to a member 52 which is periodically rotated through 180‹ as the toe and heel are being operated on and provided with a cam track 49<1> as described in the prior Specification. The cam-track 49<1> reciprocates a slide 135 carrying pivots for a lever 138 linked to the slide 148 and an extension from a lever 130, these two levers producing, respectively, the longitudinal movement and tip of the work. The lever 138 is guided by a member 140 engaging the sides of the lever and pivoted in a slide 141 engaging inclined slots 52<1> in the member 52, the arrangement providing an adjustable fulcrum for the lever, an arm 144 keyed to a pivot 143 to which is also keyed an arm 142 having at its end a spring plunger which can engage any one of a series of vertically spaced holes in the member 52 affording adjusting means for the fulcrum. The lever 130 is slotted to allow adjustment of the lower end of a link 128 towards or from the pivot of the lever, the link tipping the member 127 about its pivot. In a modification, the lever 130 is not connected to the slide 135, but is extended to engage a bar reciprocated vertically by a second cam-track formed in the member 49.

Abstract: 559,113. Control of A.C. motors. BRITISH THOMSON-HOUSTON CO., Ltd. June 29, 1942, No. 8942. Convention date, June 27, 1941. [Class 38 (iii)] Upon reversal, a split-phase motor 13 is plugged during the whole of the decelerating period. On closing a switch 17 upwards, the running winding winding 10 is connected for clockwise rotation and the starting winding 11 is energized in series with the de-phasing capacitor 12 over contacts 15 and 36, also relay 26 picks up over switch blade 19 and down interlocks on relay 24. At a suitable speed contacts 15 open to interrupt the circuit of starting winding 11, and contacts 16 close to hold the relay 26 up over its up interlocks. On throwing switch 17 downwards, the running winding 10 is reversed, and the starting winding 11 is re-energized over contacts 25 of relay 26 and contact 35 of switch 17, thus initiating plugging. As the motor decelerates, contacts 16 open to interrupt the holding circuit of relay 26, which drops and allows relay 24 to lift, and contacts 15 reclose the normal starting circuit. Thus the motor continues to be plugged to rest and then accelerates in the opposite direction. A similar action occurs if the switch is thrown from its lower to its upper position. A resistance 38 may be included to limit the plugging current whilst the contacts 16 are closed. Specification 526,750 is referred to.
