Abstract: 1284898 Chance apparatus PHONOGRAPHIC TECHNICAL Ltd 2 Nov 1970 [5 Nov 1969] 54219/69 Heading A6H [Also in Division G4] A coin or token operated amusement apparatus in which two games of chance are played simultaneously comprises first and second machine units; the first machine unit includes a panel 15 which contains a number of positions at which either of two symbols, e.g. a ball and an arrow is indicated, said positions being arranged in pairs one for each of the two symbols, which are placed in a predetermined juxtaposed relation to each other; the second machine unit being of the "fruit machine" type but modified to include another drum 28 which indicates the odds the apparatus pays out for the game successfully played on the first machine unit. The operation of the apparatus is as follows: a player inserts a coin or token through slot 17 and activates the apparatus by depressing lever 47. The first machine unit, which has three random selection mechanisms, one for each of the two symbols and the other for the odds indicator drum 28, selects a random position for the arrow, which position is shown on panel 15 by illumination thereof, and at the same time the three drums 25, 26, 27 of the "fruit machine" are set in motion. The random ball and odds selection mechanism are also activated. The drums 25, 26, 27 stop first and thereafter the random ball and odds selection mechanism stop simultaneously at the end of their preset cycle. If the ball illuminated on panel 15 is in the predetermined juxtaposed relation to the illuminated arrow, the apparatus pays out according to the odds shown on the drum 28 which is numbered from 1 to 10, i.e. if drum 28 indicates number 5, the apparatus pays five times the value of the coin or token inserted in the slot 17. The drums 25, 26, 27 apart from the usual fruit representations and the like also include representations of the ball and for every ball visible through the respective windows on panel 22, the apparatus illuminates one or more additional arrows on panel 15 thus giving the player extra chances of winning. If the player is fortunate enough to win the ball and arrow game as well as the game on the "fruit machine", the apparatus compares the two odds and pays out the highest to the player. The player may win on the "fruit machine" only, the apparatus then pays out the odds as shown on panel 29. The player may hold any of the drums 25, 26, 27 by pressing respective buttons 48, 49, 50 and he can cancel his choice by pressing button 51. The number of games credited to the player is shown at 46. Slot 19 accepts coins of higher denominations. Tray 20 is for collection of the prize or change and 21 is the prize release button.

Abstract: 1457434 Tractor-trailer braking WABCO WESTINGHOUSE 7 Dec 1973 [8 Dec 1972] 56964/73 Heading F2F A fluid pressure operable tractor braking system, for tractor braking and for supplying pressure signals for trailer braking, has a direct brake pipe 11 supplied by a source 56 via a relay valve 38 for providing a pressure signal for trailer brake actuation in response to a pressure signal at a first input of the valve, and an automatic pipe 10, normally supplied with fluid pressure and connected to a second valve input, providing a connection to a trailer emergency line 13 and affording the sole path for charging the source so that heavy demands on the source drop the pressure in the automatic line to cause trailer brake actuation by means of the emergency line. An air compressor 1 feeds front brake and rear brake reservoirs 66, 67 respectively via protection valves, controlled by a pedal 6; brake lines to the brakes also feed chambers 51, 64 (see Fig. 2) of the relay valve 38 whereby pressure increase in either chamber causes the source 56 e.g. a reservoir to be connected via a chamber 55 and a chamber 52 to an output 53 to feed the direct pipe 11. This pipe operates a trailer relay valve 15 to feed trailer brake lines from a reservoir 27 at a higher pressure than those of the tractor brake lines to avoid jack-knifing. The reservoirs 66, 67 provide the pressure for the automatic pipe 10 via one-way valves 69, 70, a common chamber 68, a braking valve 71, which has a predetermined difference between opening and closing pressures, and a regulator 72, and to supply the reservoir 56 and a chamber 55 of the valve 38 such that a decrease therein feeds the direct line 11. A pre-set relief valve 12 controls trailer emergency line pressure. As well as the provision against heavy demand on the source 56, if the pipe 11 ruptures, the source is exhausted to drop the automatic pressure, likewise caused if a rupture occurs in the pipe 10. The trailer emergency braking occurs by operation of the valve 15 when the input via the emergency line drops.

A machine for sharpening cutting tools, such as the cutting bits of mining machinery, coinprises a grinding wheel 2 fixed on a spindle 1, a carriage 17 provided with a clamping fixture 20 for gripping a tool 24 to be sharpened, an elastic member 8 for controlling the pressure between the tool being sharpened and the wheel, the spindle being mounted in a rotatable sleeve 4 which is coupled to the elastic member. The spindle is rotatable in bearings- 3 eccentrically disposed within the sleeve, the spindle being rotated by a belt-drive 10 from a motor 9 which also, through belt-drive 11, gearing 12 and a holder mounted on sleeve 4, rotates the sleeve so that the grinding wheel moves with a planetary motion. The elastic member consists of springs 8 which act through rollers 7 bearing against the holder 6 to urge the grinding wheel towards the left, as shown in Fig. 1. The frame 5 of the machine slidably receives guide rods 14 carrying the carriage 17 which is movable towards and from the grinding wheel by a cylinder 15. The carriage supports an oscillating piston 19 which carries the clamping fixture 20 comprising a lower jaw 21 and an upper jaw 23 movable by a piston 22 to clamp a tool 24 to be sharpened. The carriage 17 is movable between an operative position against the grinding wheel and a loading and unloading device comprising two shoots 25, 26, shoot 25 having a swivelling element 28 for centring a tool 24<SP>1</SP> to be sharpened and a spring-loaded stop 33 for removing ground tools from the clamping fixture. In operation, the carriage carrying a tool is advanced by cylinder 15 to engage the tool with the wheel 2, the wheel and sleeve moving against springs 8 so that grinding is effected at a constant pressure. After a predetermined number of oscillations by piston 19, the carriage is moved to the shoots 25, 26 so that the ground tool, upon release by jaw 23, is knocked from the clamp by stop 33 and the new tool is inserted and then gripped by jaw 23. The wheel may be dressed after each grinding operation and when held against axial movement by a device 41 moving a roller 42 to hold the holder 6 against a roller 43. The dresser attachment comprises a dressing tool 39, carried by a nut 38 on a screw 37 connected to a ratchet wheel 36 rotatable by a toothed quadrant 34 engaging a progressively movable rack 34 whereby the dressing tool is advanced for each dressing operation. When the wheel 2 is worn out, the dressing tool can be retracted by rotation of a handle 40.
