Abstract: 1,237,336. Turf-cutting machine. P. BIBBY. 27 April, 1970 [31 Oct., 1969], No. 53381/69. Heading A1E. A turf cutting machine 1 has side blades 18 and a horizontal blade 20 for cutting strips of turf from the ground, and a guillotine blade 21 which performs a vertical cutting action on a turf strip to form predetermined lengths of strip. A turf roll-starter unit 16 which consists of a convex holding-down component 22 and a concave scoop 25, is mounted behind the blade 21. In use the guillotine 21, having cut a turf (T), Fig. 4 (not shown), lifts the edge of the turf and turns it over, see Fig. 5, and as machine 1 progresses the component 22 rolls over the turned over portion of the turf, thus preventing it from falling back on to the ground. Component 22 moves against the action of a spring (24), Fig. 3 (not shown), and returns to its normal position while the scoop 25 engages the edge of the rolled-over turf, lifts it forwardly so that the cut end of the turf is tucked in and a roll is started. A rack (17), Fig. 14 (not shown), which has blades (17d) commences to act upon the "started" roll, preventing it from un-. rolling as the scoop 25 is carried clear and returns to its normal position under the action of a spring (29), Fig. 3 (not shown), while the rack (17) completes the rolling operation.

Title: Method of and apparatus for plunge grinding screwthreads
IPC: B23G1/40
Filed: 1973-11-20
Abstract: 1433369 Grinding screw threads ZAHNRADFABRIK FRIEDRICHSHAFEN AG 20 Nov 1973 [2 Dec 1972] 53733/73 Heading B3D A method of plunge grinding screw threads, for example, internal screw threads in a ring 0, using a multiple profiled cylindrical grinding wheel 12, comprises advancing the workpiece spindle 1 with respect to the grinding wheel spindle during a revolution by a distance equal to the screw thread pitch, the advancing movement and the plunging movement commencing simultaneously and the workpiece performing rotary and advance movements in alternate directions with continuous plunging by the grinding wheel until the final screwthread depth is attained. In apparatus for carrying out the method, the workpiece is mounted in a chuck 2 on the spindle 1 which is mounted in an upper section 4 of a work carriage and rotated by an hydraulic servomotor 5. The upper section is adjustable about a vertical axis S1 on a lower section for grinding the screw thread on the conical inner surface of the workpiece. A gear 41 is secured to the spindle and engages a rack 42 which is guided for movement in the upper section and has a pin 14 engaging a guide rail 16 angularly adjustable to the helix angle # of the screw thread, a spring 15 acting between a fixed member 17 and the lower section 8 of the work carriage to urge the carriage along guides 9 on the bed of the machine so that the pin 14 is held against the rail 16. The grinding wheel is dressed by a trueing wheel 29 movable about an axis A between operative and inoperative positions, the grinding wheel being carried by a bracket 11 transversely movable along a longitudinally movable bracket 13. In operation, the upper section 4 is adjusted to the angle α of the conical surface of the workpiece, and the guide rail 16 is adjusted to the angle # of the helix of the screw thread. After the grinding wheel is trued it is moved into the workpiece without touching the latter. Simultaneously with feeding the grinding wheel into the workpiece, the motor 5 is started to rotate the workpiece which is also fed axially of the grinding wheel as the pin 14 is moved along the guide rail. After approximately 1À1 revolutions, the direction of rotation of the spindle and hence the direction of the axial movement is reversed, the grinding wheel continuing to plunge grind the workpiece and the process continuing until the final depth of thread is reached. In another embodiment the rack is formed on a double acting hydraulic motor which acts to drive the spindle instead of the motor 5. In a further embodiment, a cam (30, Fig. 5, not shown) is mounted on the spindle and engages a roller (32) mounted on a block (33) fixed to the machine table.

Title: Process for the production of terephthalate polyester lacquers
Inventor: MORGNER JOACHIM
IPC: C08G63/20
Filed: 1965-12-30
Abstract: Polyester lacquer resins containing more than 40 mol per cent terephthalic acid (including any other acids present) are prepared by the reaction of polyethylene terephthalate with polyols containing 3 or more hydroxy groups, possibly mixed with diols, wherein the ethylene glycol formed is either removed by azeotropic distillation or is chemically bound by the addition of the required amount of an aromatic and/or aliphatic polycarboxylic acid or an anhydride or C1- 4 alkyl ester thereof. Suitable polyols are glycerol, trimethylolethane and trimethylolpropane, which may be mixed with a diol, e.g. propylene glycol.  Transesterification catalysts may be used, e.g. PbO, CaO, and Pb(OOC.CH3)2.  Suitable entraining agents for the azeotropic distillation are tetrachloroethylene, ethylene glycol monoacetate, toluene, the cresols and the xylenes.  The polyesters are dissolved in cresol, viscosity is adjusted with xylene, and a cross-linking agent, e.g. butyl titanate, is added to give a stoving lacquer for wires.  A modified polyester for lacquers for thick wires is obtained by substituting for part or all of the added terephthalate ester normally preferred another acid, in particular adipic, sebacic or isphthalic acid or a benzene tricarboxylic acid or pyromellitic acid.

Abstract: 1,217,263. Fluid-pressure lifting devices. STABILUS INDUSTRIE-UND HANDELS G.m.b.H. 28 Nov., 1968 [30 Nov., 1967], No. 56552/68. Heading B8J. A fluid pressure device for adjusting the height of a table comprises, Fig. 1, a cylinder 1 with a piston 2 dividing the cylinder cavity which is filled with fluid under pressure, into a lower compartment 3 and an upper compartment 4. A tubular piston-rod 5 extends from the piston 2 into the ambient atmosphere. A valve operating rod 6 is received with clearance in bore 15 of the rod 5. In the normal operating position, as shown, the device is locked. If it is desired to adjust the effective length of the device rod 6 is pressed into the cylinder 1 to an amount limited by ring 10 abutting ring 11. This opens a passage between the compartments 3, 4, a valve sealing collar 18 being bridged by flared portion 19 to allow fluid to pass through radial bore 35 and bore 16. The internal pressure in the cylinder 1 is normally more than adequate to expel the piston-rod 5 from the cylinder 1 against the frictional resistance of a seal 31. If it is desired to shorten the device the rod 5 is pushed inwards while the valve sealing collar 18 is bridged. The force required to shorten the device is opposed by the pressure inside the cylinder 1 and when this is too great for a particular application it may be reduced by removing the ring 10 and pushing the rod 6 inwards until the turns of return spring 14 abut. This provides a third position for the rod 6 in which a notch 8 bridges a valve sealing collar 9 and compressed fluid is allowed to escape from the upper compartment 4 through bore 16, radial bore 35 notch 8 and the annular clearance between the rods 5, 6 in bore 15, to the atmosphere. Fig. 2 shows a modification with corresponding elements having the same reference numerals as in Fig. 1 but augmented by 100. Lower compartment 103 is axially divided by a floating sealing piston 145 into two portions respectively adjacent to and remote from the piston 102. The adjacent portion of compartment 103 and compartment 104 are completely filled with incompressible liquid, while the remote portion of the compartment 103 is filled with gas under high pressure. This apparatus acts substantially as that described with reference to Fig. 1. If it is satisfactory to move the rod 6 by hand in both directions the spring 14, Fig. 1, may be dispensed with. Reference has been directed by the Comptroller to Specifications 1,123,030 and 1,139,561.
