Abstract: 1,157,782. Tracked vehicles. ORENSTEIN KOPPEL UND LœBECKER MASCHINENBAU A.G. 23 June, 1967 [5 July, 1966], No. 29140/67. Heading B7H. [Also in Division F2] A tracked excavator having its tracks driven by hydraulic motors 21, 22 and its soil-working devices operated by hydraulic cylinders 7-10, comprises an hydraulic pump 1 connected in sequence to cylinder control valves 3-6 and to motor control valves 12, 13, and a flow divider 15 which in use supplies the motors 21, 22 and is fed by bleed 23, the valves 3-6, 12, 13 being such that when they are all set at neutral, the pump output line 2 communicates with the sump 16, but in all other control positions the line 2 is blocked. Thus, actuation of either or both the motor valves 12, 13 blocks the pipe 14 and all the pump output is divided by the divider 15 between the valves 12, 13 which either supply the motors 21, 22 or return the oil to the sump lines 19, 20, according to whether they have been operated or not. The valves 12, 13 may be 6- or 8-way valves. The divider 15 comprises two positive displacement hydraulic motors of like volume, mechanically coupled together.

Abstract: 1306097 Photo-electric control TEIJIN Ltd 22 April 1970 [23 April 1969] 19362/70 Heading G1A [Also in Division D1] A photo-electric switching system is used to cause reversal of a reciprocating rail 7 in a spinning machine. The photo-electric system comprises a light source (not shown), a lightreceiving device 20 and a pattern member 18, there being relative reciprocal movement between the pattern member (connected mechanically to rail 7) and the light source and device 20 with switching to the reverse direction of movement when the pattern member passes from between the source and device 20 so that light falls on the device. The pattern member 18 is also moved vertically by motor 23 rotating threaded rod 16 engaging with the pattern member support. The horizontal movement of the pattern member 18 limits the distance moved by the rail 7 and the vertical movement of pattern member 18 varies the distance moved by the rail 7.

Abstract: 1,019,713. Bundling-machines. R. A. LOMBARDE. Aug. 1, 1962 [Feb. 14, 1962], No. 29503/62. Heading B8C. [Also in Division B6] A machine for stacking and bundling .flat articles such as collapsed tubular cartons- 41 comprises lower carrier means 62 to advance a stack of articles horizontally from a stacking station 26 through a tying station 27 to a discharge station 28; a hopper 49 mounted over the carrier at. the stacking station; upper carrier and pressure means 87 extending horizontally from the stacking station and through the tying station; indexing means to advance the upper and lower carrier means a predetermined distance, and counting means at the stacking station to actuate the indexing means when a predetermined number of articles has accumulated in said hopper. Collapsed cartons 41 advance in shingled formation along a conveyer 29, which may be raised to permit manual bundling and tying when desired, to a conveyer 44 above which is situated a pair of adjustable hold-down rolls 51. To ensure that the cartons descend in the hopper 49 horizontally, a roll 59 having a peripheral speed considerably greater than that of the conveyer 44 is provided frictionally to engage each carton and advance it over the open top of the hopper 49. A photo-electric device 184, 185 (Fig. 5, not shown) counts the cartons as they pass into the hopper 49, and when a predetermined number has passed through, actuates a switch to advance the stack out of the hopper. The edges of the cartons are aligned by laterally and longitudinally adjustable pushers 160, 161 (Fig. 5, 6, not shown) and are gripped between upper and lower belts 87, 62 the indexing of which is initiated by the switch actuated by the counting mechanism. Advancement of the stack pushes open gates 191, 192 (Fig. 6, not shown) co-extensive in height with the hopper. Simultaneously rods 204, 207 and bell-crank levers 206, 208 (see also Fig. 4, not shown) (in the case of short cartons) and/or trapdoors 215, 216 (in the case of long cartons) are advanced into the path of the next following cartons; the cartons are allowed to fall to the bottom of the hopper when gates 191, 192 close again. The counted stacks are compressed between the moving belts 87, 62 as they advance to conventional knot-tying means, 120. The hopper rear and side walls 57, 55, 56 (Fig. 4, not shown), the height of the rods 204, 207 and trapdoors 215, 216, the distance between the conveyers 62, 87, and the frames at each side thereof are all adjustable by power-operated means. The upper conveyer 87, tying means 120, pusher arms 160, 161 and gates 191 and 192 may be disconnected so that the machine may be used simply to form counted stacks of cartons, and the lower conveyer may then index forwardly or advance continuously, the stacks being accumulated on the trapdoors.

SAVY, JEANJEAN, & CIE, Avenue Dubonnet, Courbevoie, Seine, France. Oct. 25, 1933, No. 29552. [Class 59] Refiner &c. rolls are cooled by maintaining a body of water within the roll, circulating it at a rapid rate (such as 10-12 gallons per minute) and causing the water to pass in contact with the inner periphery of the roll through a series of restricted passages spaced apart axially of the roll. The roll 1, Fig. 1, has a hollow trunnion 5 through which passes a cooling- water inlet pipe 9, the discharge taking place between the pipe and the bore through the trunnion.

Abstract: 1,045,877. Making dies. WILLIAM CROSLAND Ltd. Oct. 1, 1963 [Aug. 4, 1962], No. 30101/62. Headings B3A. [Also in Division B4] A method of making a die comprises the steps of locating and securing a template and guide pins on a first base-plate, locating guide-pin bushes on the guide-pins, locating a frame on the base-plate around the template and bushes, pouring plastic material into the area defined by the frame and template and curing it, removing the frame, plastic, template and guide bushes together, and using the template as a guide sawing therearound to remove a core of plastic material, reducing the thickness of the core, locating steel rule inserts in the aperture so formed in the plastic material, wedging the rules by inserting the reduced core and mounting the die so formed on a second base-plate. A male die part is produced by making a template 10 of tool-steel which is secured to a base-plate 12 by bolts 13, Fig. 1 (not shown). Guide pins 14 are also secured to the base-plate. To produce the female die half a rectangular frame 15, Fig. 2 (not shown), is located on the baseplate surrounding the template and guide-pins, and phosphor bronze bushes 16 are placed on the guide-pins. A piece of high density wood 17 which is larger than the template is marked with the shape of the template, which is then removed from the base-plate, and in its place is secured the wood with the marked area accurately in the position formerly occupied by the template. A plastic material is then poured into the space between the frame 15 and the wood 17, and is cured, so that the frame 15, wood 17 and bushes 16 are held together, and the assembly is removed from the base-plate 12. The wood 17 is now sawn to remove therefrom a core whose shape corresponds to the shape of the template 10, the thickness of the core is reduced, the aperture formed in the wood is lined with steel rule 19 and the reduced thickness core 17a is replaced to hold the rule in position. The female die part so formed is mounted on a base-plate 20. The template 10 is re-attached to the base-plate 12 to form the male die part. Ejection rubbers 21 are mounted on the core 17a and on the base-plate 12.
