Title: Improvements in safety devices for manually- or foot-operated machines
IPC: F16P3/04
Filed: 1951-05-08
Abstract: 711,800. Machinery guards. PARKES, H. L., and GAUNT & SON, Ltd., J. R. May 8, 1952 [May 8, 1951; Nov. 16, 1951], Nos. 10751/51 and 26860/51. Class 80 (4) A guard for a fly or kick press, or for other machines-such as for diecasting, moulding or spot-welding- having one or more tool-carrying members reciprocated by hand or foot power, comprises a ring 13, or other guard, which descends ahead of the ram 12 and which co-operates with a spring-loaded arrester mechanism so that df the guard's descent is obstructed (e.g. by an operator's hand) the mechanism is tripped and an arrester head 31 is moved into the path of a collar 36 on the ram, thereby preventing its descent. The ring 13 is carried by a pair of rods 16 supported in a fixed guide 19 and in a guide 17 on the ram, collars 18 on the rods locating the ring relatively to the ram. A channelled' extension 24 of the fixed guide 19 houses a slidable arrester body 27, Fig. 3, which carries the head 31 and is bored to receive a compression spring engaging an adjustable fixed screw 33. A recess 38 in the lower face of the body 27 is engaged By a catch 39, the catch comprising a bell crank having projecting stubs 43 against which bears a pair of cranked rods 44. The rods 44 are pivoted to the guide 17 on the ram, and a deflector 46 secured to the rods 16 coacts with the cranked parts 45, so that if the guard ring 13 is obstructed in its descent the consequent relative movement between the rods 16 and the ram causes the rods 44 to release the catch 39. The head 31 may be C or U shaped to embrace the screwed rod which carries the collar 36 and is part of the ram structure. The abutment face of the recess 38 may be approximately tangential to the path of the catch 39. Alternative shapes of arrester head may be secured to the body 27, a weighted lever or a tension spring may replace the compression spring, and the catch may be in the form of a pivoted hook. According to the first Provisional Specification the arrester'is biased to an inoperative position and obstruction of the guard causes it to be moved against the biasing means.

Title: Improvements in or relating to magnetic tape recording systems
IPC: G11B5/03
Filed: 1966-03-11
Abstract: 1,148,461. Recording colour signals. IIT RESEARCH INSTITUTE. 11 March, 1966 [12 March, 1965], No. 10844/66. Heading G5R. In an arrangement for recording colour video signals on tape, three heads, 16, 17, 18 recording respectively the R, G and B signals are fed with a bias signal from a common supply. The heads have their normal windings 57<SP>1</SP>, 581; 75, 76 and 27, 28 connected via respective amplifiers 71, 72 and 73 to a colour signal source 60 and cross field bias windings 93, 94, 95 connected in series to a video bias supply 91 which is also connected via capacitors 113-115 to the normal windings. The video heads 16, 18 are narrow and each is associated with an audio head 32, 33 for recording stereophonic sound. Each audio head includes a pair of gaps whereby a transversely magnetized audio track is recorded on each side of the associated longitudinally magnetized video track. The magnetic circuits of the audio heads are completed via the portions 30a, 30b of the tape engaging surface 30 which is formed of soft magnetic material. The combined video and audio tracks e.g. R1, 54, 55 associated with video head 16 and audio head 32 occupy the same width of tape as the wide video channel G1 &c. produced by video head 17, thus allowing one or more further sets of tracks to be recorded by fixed step lateral movements of the tape by shifting means 105. Where the tape drive is reversed after shifting of the tape the phase of the bias signal applied to the cross field windings 93-95 is reversed by switch 111. In a second arrangement the audio tracks are disposed on one side only of tracks produced by the outer video heads. The tape engaging surface 14, 30 of the head units is formed of a soft magnetic material whereby the surface 30 acts as a beeper for the video tracks when these pass the audio heads and the surface 14 acts as a beeper for the audio tracks as these pass the video heads. The colour video signal having the greatest band width, i.e. the green colour in the arrangement described, is recorded by the wide head 17.

Title: A process for washing soap
IPC: C11D13/04
Filed: 1962-03-21
Abstract: <PICT:0989745/C4-C5/1> Crude soap is washed by countercurrent contact with lye in a pulse column 1 having perforated plates 2-6, which cause the cross-sectional area of the mixture to be contracted and expanded along the length of the washing zone.  The crude soap preferably enters at 10 and passes upwards through the column while the fresh washing lye enters at 11 and passes downwards.  The plate perforations have a diameter of 1-10, preferably 2-6 mm. and reduce the volume of the soap grains to less than 100 mm.3 The plates are spaced 2-20 cm. apart, and the pulses, of frequency 50-300, preferably 100-200, per minute and wavelength 2-50, preferably 5-30 mms. are produced by pulsing means 7. The washed soap passes to settling zone 9 before being drawn off at 12, while the used lye is separated from crude soap in zone 8 before being withdrawn through 13.  In general, the washing lye has a concentration approximately or slightly below that of the "limit lye," i.e. the maximum concentration at which the soap is soluble in the lye.  Suitable lyes comprise mixtures of soda and salt.

Labelling.-In a machine for applying labels, stamps &c. to packets, of the kind described in Specification 22932/14, in which a gum plate applies gum to a label &c. and removes it from a pile the label being then seized by a gripper plate which applies it to the packet, the transfer of the gummed label being effected at a station past which the two plates move synchronously in the same direction and in paths which approach each other and then recede from one another, the gum and gripper plates are rotatable about parallel axes and are movable in directions radial to the axes. The machine shown is for applying labels along one side and both ends of packets of tea which are fed by an intermittently-operated conveyer 11, Fig. 1, provided with channel-shaped holders 12 from which the packets are pushed transversely into an intermittently-rotated pocket wheel 18 from which they are discharged, after the label has been attached, by a pusher 21 into a channel the sides of which may be provided with brushes which fold the ends of the label over the ends of the packet. The gum plate 51, supplied by a a roller 126, is mounted on a stem 55, Fig. 5, slidably mounted in a carrier 52 which can be rocked about a shaft 56 to present the gum plate to the gumming position shown and pile of labels respectively. This is effected by an oscillating sector 90 and gears 54, 74. Radial movement of the gum plate is effected by means of a pinion 58, Fig. 5, engaging rack teeth on the stem 55, the pinion being rotated by teeth 57 formed on the forked end 59 of the shaft 56, longitudinal movement of which is effected by a cam-operated lever 60 and connections 62, 63. The gripper plate 71 is similarly mounted for rocking and radial movement about an axis parallel with the shaft 56, and is provided with pivoted grippers 100 which are mounted on a rock shaft 101 operated by a cam 103 on a longitudinally-movable shaft 102. Fig. 9 shows the gum and gripper plates in the transfer position. The gum plate has left the label pile 112 with a label adhering thereto. The grippers 100 seize the projecting edge of the label and strip it from the gum plate. The gripper plate then carries the label till it is vertically over the packet in the top-most pocket of the pocketwheel when the gripper plate is moved radially downwards to stick the label to the packet. The various parts are operated by cams on the main shaft 33.

Title: Improvements in fluid-actuated motors
IPC: F03C1/04
Filed: 1941-09-01
Abstract: 558,771. Liquid motors. DOWTY EQUIPMENT, Ltd., and BURKE, P. W. Sept. 1, 1941, No. 11169. [Class 69 (ii)] A hydraulic motor, which can be combined with a similar pump unit such as is described in Specifications 524,199; 524,384, and 534,847, [all in Group XXVIII], to form a variable hydraulic gear, is constructed of a rotatable cylinder assembly 7 which rotates around a fixed valve 6 with inlets 9, 10 and. outlets 11, 12, and the cylinder is provided with a number of pistons 14 provided with rollers 16 mounted in ball bearings and controlled by a track ring 17 mounted within an annulus 3 which together with end walls 4, 5 from the motor casing. The ring 17 can be adjusted about a knife-edge connection with a bearing block 18, and normally is maintained in contact with a stop 22 by an Euler strut 19 arranged between a fixed anchorage 20 and projection 21 on the ring. The ring 17 is then slightly eccentric to the rotor cylinder assembly 7 and if the input is at a given rate at substantial pressure the rotor will rotate at a predetermined rate proportional to the input so long as the thrust reaction loads, the resultant of which acts in the direction of the arrow Y, Fig. 2, are not sufficient to overcome the centralising movement of the strut 19. At higher torque load this centralising movement is overcome and the eccentricity of ring 17 is increased with resultant increase in throughput capacity per revolution of the motor, so that the speed of the motor is then inversely proportional to the torque loads opposing motion. A spring-loaded relief valve 25 opens at a given pressure to connect the inlet 9 to the outlet 10 so that excessive pressures are not admitted to the inlet 10. The Euler strut may be replaced by a coil spring. When a coil spring is used the eccentricity of the ring 17 increases gradually with consequent gradual decrease in shaft speed at increased torque. The driven shaft 8 is locked to or formed integrally with the hub of the rotor 7. A port 26 enables cooling or lubricating liquid to pass into the interior of the motor.
