Title: Improvements in or relating to a swivelling mechanism for machine tools
IPC: B24B19/06
Filed: 1954-12-30
Abstract: 766,499. Grinding machines. MESSERSCHMIDT, S. Dec. 30, 1954 [Feb. 15, 1954], No. 37670/54. Class 60 In a grinding machine with a tool (not shown) and a chuck 2 oscillatable relatively to each other, the amplitude of the relative oscillation is increased to a predetermined value and then decreased to zero to permit final plunge grinding of the workpiece 1 which may be a bearing race. The chuck 2 is oscillated about a point O by a connecting rod 5 and a rotating crank pin 7. The latter is mounted on a slide 43 which is rotated by a hollow shaft 38 driven by a worm drive 36, 37 and may be displaced radially by a screwed spindle 39. A bevel wheel 40 on this spindle meshes with a pair of bevel wheels 23, 24 adapted to be selectively engaged by a clutch 22 with a rotating shaft 20 which may also be displaced in an upward or downward direction from the position shown by a cam-operated linkage 15, 16. When the shaft 20 is moved downwardly, the bevel wheel 24 is driven and the slide 43 moved radially outwards by the driven spindle 39 until an abutment 34' engages an abutment 34 which rocks a member 26 about a pivot 27 to restore the clutch 22 to neutral position. The member 26 has three recesses 29, 30, 31 to co-operate with a spring-loaded plunger 28 so that the clutch is retained in the position to which it is moved. Upward movement of the shaft 20 causes the bevel wheel 23 to rotate the spindle 39 and the slide 43 to be moved radially inwardly until the throw of the crank is zero when the clutch 22 is again restored to neutral position by an abutment 33 striking the control member 26.

Abstract: 1,218,914. Phosphorus-containing polymers. SHELL INTERNATIONALE RESEARCH MAATSCHAPPIJ N.V. 28 July, 1969 [30 July, 1968], No. 37682/69. Heading C3P. Polymers of the formula wherein B is a conjugated diene polymer block or a vinyl aromatic hydrocarbon polymer block, R 1  and R 2  are independently selected hydrocarbon groups. A is a polymer block of an unsaturated polar monomer, n is zero or 1 and m is an integer from 1 to 5 are prepared by polymerizing a conjugated diene or a vinyl aromatic compound with an initiator of formula (II) wherein M is an alkali metal, R 1  is as above and R<SP>1</SP> 2  is R 2  or a group and optionally polymerizing the phosphineterminated polymer with a polar monomer. Polymers produced are (ethyl)2 P-polybutadiene-Li and (ethyl) 2 -polystyrene-Li which were coupled with diethyl adipate. The polymers may also be made by polymerizing the monomers with a dilithium initiator to form a dilithio terminated polymer which is reacted with a dihydrocarbyl halophosphine. Thus dilithium terminated polybutadiene was reacted with diethyl chlorophosphine and the phosphine terminated polymer was used to initiate the block polymerization therewith of acrylonitrile.

Title: Skinning machine
IPC: A22C17/12
Filed: 1946-12-23
Abstract: 621,825. Skinning-machines. TOWNSEND, R. T. Dec. 23, 1946, No. 37753. [Class 28(ii)] In a skinning machine, particularly for hams, shoulders and backs, a piece of meat 65, Fig. 5 placed skin down on a support table 52 is pulled against a skinning edge 32 by a skin engaging rotated roller 7-12 which carries the detached skin around until it is stripped off by fixed plates 62. The thickness of skin cut off is determined by the position of the edge 32 over the roller, the edge plate 31 being adjustably clamped between parts 27-28 which also form skin guiding curve 29 all of which constitutes a pressure shoe. The pressure shoe is pivoted at 38 and is biassed by a spring 40 to rise up, but is held down in position during cutting by a treadle and rod 43 attached to pivoted arms 36 which bear on the pressure shoe. The stripper plates 62 surround the roller, being located in grooves between the teeth 12 but are prevented from rotating with the roller by their extension 63 abutting against the top of the machine frame. After stripping the skin 66 is deflected by a baffle 64 into a receptacle. To skin round pieces 67 such as hams, shoulders &c., the table 52 is inverted as at Fig. 4 and adjusted about its pivot 55 by screws 59 as required. Where the skin entirely surrounds the meat it is only slit and placed adjacent the knife edge 32. The meat 67 lies along the bevel of the edges of the table. End rings of the roller prevent the table 52 from fouling the teeth of the roller. To facilitate cleaning the roller the knife 31 and pressure shoe 26-27 can be pivoted away from the roller, and similarly the table 52 can be pivoted away so that the roller can be lifted out and its shaft pulled out axially so that its rings 8 are disassembled and can be removed from the interdigital stripping plates, all of which can then be cleaned individually. When a blunt edged blade (101, Fig. 9 not shown) is used instead of the knife edge 32 the skin is separated from the flesh at the natural parting place.

Title: Improvements in or relating to the separation of sheets of paper and the like from apile
IPC: B65H3/10
Filed: 1928-12-21
Abstract: 303,015. Spiess, G. Dec. 24, 1927, [Convention date]. Sheet-separators ; pile supports; sheet-guides. -Sheets are separated and advanced from a fanned-out pile by oscillating the front edge of the pile projecting from a table 1 by means of curved supports 3 into and out of contact with suction rollers 15 of the kind which comprise series of radial holes in an outer sleeve member revolving on a stationary hollow member 17 provided with a slit with which the radial holes connect in succession. The top sheet is thus caused to adhere to the rollers 15, which are oscillated by cam and sector gear mechanism, or, as shown in Fig. 7, are driven from a continuously driven gear 46 by a spring coupling 47, 48, which permits the rollers 15 to be held stationary by a cam-oscillated stop 51 while the sheets are raised, and then to move on with increased speed until the spring 47 is reieved of the compression due to the stoppage of pin 48. While the sheets are being raised they are acted on by air blasts from inclined ports 10, Fig. 3, of a blast chamber 8 and from ports 9 of an auxiliary chamber 8a. Or an oscillating blast chamber interconnected to the supports 3 may be employed. The action of the successive suction apertures in the rollers 15 advances the separated sheet between guides 18 to feed rollers 6, 7, of which the upper set rise, and fall periodically. The suction action is broken by mechanism controlled by a feeler 20, Fig. 1, which when acted on by the sheet causes a valve 38 to be opened to admit air to the hollow member 17. The feeler 20 is controlled by a spring 25 and is pivoted to cheeks 23 suspended freely from a shaft 24 and a projection 23<a> is normally held by a catch on a lever 26 in the position shown in Fig. 1, a spring 27 connected to the cheeks 23 assisting to maintain the feeler mechanism in normal position. The separated sheet acts on faeler 20 and moves lever 22 clockwise into contact with a ratchet 31 on the main shaft 14. This ratchet moves the cheeks 23 clockwise, and releases the projection 23<a> from lever 26, so that the cheeks move under gravity in a clockwise direction until the lever 26 engages a second projection 23<b> on the cheeks, and the lever 22 becomes disengaged from the ratchet 31. The lever 26 is then held by a spring 30 connected by a lever 28 to the spring 27 connected to the cheeks 23. This movement of lever 26 is transmitted to a link 32 on which is a cam projection which depresses the stem of valve rod 39 of valve 38 and thus connects the member 17 to atmosphere. The parts are re-set by a cam 36 acting on a lever 34 connected to link 32, which when returned to normal position causes valve 38 to close and also returns lever 26 to normal position, and with it the other associated parts also return to the normal position shown in Fig. 1.

A centrifugal clutch for coupling a driving drum 2 to a driven drum 5 and particularly for use in vehicles comprises a series of weights 9 each secured to one end of a spring 6 secured to the drum 2. The other end of each spring 6 supports an auxiliary shoe 11 pressed into engagement with the drum 5 by a light spring 13. This end of the spring 6 is inclined to a radius so that in one direction of relative rotation between the drums 2 and 5 it wedges to transmit a drive whilst in the other direction it merely rubs lightly on drum 5 and transmits negligible torque. Thus drum 2 rotating in the direction of the arrow only transmits torque through the centrifugal action of the weight 9 in proportion to the speed to the drum 5. If, however, the drum 5 tends to over-run the drum 2 or if the drum 5 drives whilst the drum 2 is stationary, the shoes 11 tend to wedge and transmit substantial torque. This provides for engine braking and a towed start in vehicles.
