Abstract: 699,964. Collecting mechanism for cigarettes; shoots. MORRIS, J. E., and MOLINS MACHINE CO., Ltd. March 12, 1952 [Dec. 14, 1950], No. 30546/50. Classes 78 (i) and 104 (ii). The cigarette collecting mechanism claimed in Specification 649,467 has means to vibrate part of the wall of the passage through which the cigarettes pass to the collecting trays. A part 102 of the side wall 101 of the shoot is attached to the end of a lever 103 pivoted at 104 and is oscillated against the action of springs 110 by a crown cam 105 fixed to a shaft 106 driven through pulleys 107, 109 and a belt 108 bv a shaft 21. The cigarettes are fed by a star wheel 100 to a funnel shaped curved passage formed between a convex wall 113 and a front wall 114 on to a sloping guide 42 and into the collecting trays. The lower end of the guide 42 is forwardly curved to check the fall and to deposit the cigarettes into grooves in the tray bottom. To ensure uniform filling the trays are traversed slowly during the filling period and faster during the period when one tray is leaving and another tray is entering the filling position. The change in speed of the trays is effected by steps 61A, 61B and 61C formed on a pawl 61 Fig. 3 and engaging a feed bar 63. Step 61A prevents movement of bar 63, step 61B permits normal movement of the bar 63 and step 61C permits increased feeding movement, the pawl 61 being lifted to engage the step 61C and the bar 63 when the rapid build up of cigarettes in the shoot raises a detector 57. The cigarettes are levelled in the trays by a roller 112. Specification 694,334, [Group XVII], also is referred to.

Title: Method of briquetting fine-grained fuels and/or ores
Inventor: SCHMALFELD PAUL
IPC: C22B1/24
Filed: 1960-09-05
Abstract: Fine-grained ores are briquetted with a bonding medium consisting of a fraction, boiling above 250 DEG  C., of the carbonization tar obtained by the low-temperature carbonization of coal fines with the use of hot coke as heat carrier material, the briquettes being subsequently subjected to oxidative hardening. Coal fines may be mixed with 4 to 25 parts by weight of coke which has been heated to between 700 DEG  and 800 DEG  C. and simultaneously degasified until its volatile content is between 2 and 6%, the resultant coal-coke mixture being at a temperature of about 600 DEG  C.  The volatile products are drawn through the cold solid material to be briquetted which is either descending down a shaft or is in the form of a fluidized bed, and the resultant cooling causes mainly the high boiling tar constituents to condense, uniformly wetting the solids to be briquetted and also heating them to a suitable briquetting temperature of 60 DEG -80 DEG  C.  The briquettes are subsequently heated to 250 DEG  C. and treated with oxygen-containing gases. Specifications 793,518 and 844,823 are referred to.

Abstract: 1514067 Photo-electric sorting of billiard balls H S BILLIARDS Inc 23 July 1976 [6 Oct 1975] 30735/76 Heading G1A A pool table incorporates a ball separating apparatus including means for distinguishing between the all-white cue ball and the other balls, the said means comprising, at a sensing station, a number of L.E.D.'s 32A-32D and corresponding phototransistors 34A-34D each producing a signal representative of the reflectivity of part of the ball, and means responsive to the phototransistor signals for producing a first electrical signal when a cue ball passes the sensing station and a second signal when another ball passes. An all-white ball produces a signal at all the phototransistors which is less than a reference signal obtained from a separate L.E.D. 38 and phototransistor 40. Amplifier 70 then produces a high output and energizes solenoid 92 via transistor driver 78 to cause diversion of the ball into an accessible store (20), Fig. 1 (not shown) in the pool table. The coloured portion 44 of a partly coloured ball produces an output from at least one phototransistor e.g. 34D which is higher than the reference signal. In this case the amplifier 70 output is low, the solenoid is unenergized and the ball rolls into an inaccessible store (18). The circuitry is energized by a ball passing over switch 42. Adequate spacing of the balls entering the apparatus is produced by a mechanical gating arrangement Fig. 6 (not shown).

Title: Vehicle inching and braking system
Inventor: BRUKNER FRANCIS EARL
IPC: B60T11/10
Filed: 1967-07-05
Abstract: 1,141,897. Vehicle inching and braking system. CLARK EQUIPMENT CO. 5 July, 1967 [6 Sept., 1966], No. 30862/67. Headings F2D and F2F. A vehicle (e.g. a fork lift truck) inching and braking system incorporates a control valve 14 (Figs. 1, 2) having coaxial stepped pistons 32, 56 both biased in the same direction by compression springs 68, 70 respectively, the spring 68 having a higher rating than spring 70 so that when pressure fluid is applied by an actuator 16 to the piston ends via a port 44 and a chamber 40, first the piston 56 is moved to block a port 48 and then as the pressure increases piston 32 is moved. The valve is used to control clutches 84, 86 and wheel brakes 12 as described below. Operation.-If a truck is conditioned for forward drive and the operator wishes to manoeuvre the truck while elevating a load, he depresses pedal 74 thereby supplying pressure fluid via port 44 to chamber 40 which acts against piston 56 end 60 causing the piston to move against spring 70 to block a port 48 connected via a line 76 to a second pedal actuator 18. Simultaneously pressure fluid is directed via chamber 40, a port 46 and a line 80 to an inch valve 20, which thereby operates to reduce pressure to the forward clutch 84 causing it to slip (or to reversing clutch 86 depending upon which clutch is connected via a direction control valve 94). Further depression of pedal 74 causes clutch 84 to disengage. The pressure fluid for the clutches is supplied by a pump 88 fed from a reservoir 90. As the pressure in chamber 40 increases, the force on a portion 34 of piston 32 will increase causing the piston 32 to move against spring 68 thereby forcing fluid out of a chamber 42 via a port 50 and line 96 with the result that brakes 12 are applied with increasing force as piston 32 moves to the right. Preferably the application of the brakes is timed to begin when the clutch is fully disengaged, the timing being adjustable by changing the rating of spring 68. To brake the truck for a normal stop while maintaining the braking effect of the engine (i.e. with clutch still engaged), the pedal 78 is depressed so that actuator 18 supplies fluid to chamber 42 via port 48, and hence to the brakes 12 via port 50 and line 96.
