Title: Improvements in or relating to time-controlled electric switches
IPC: G04C23/16
Filed: 1933-09-30
Abstract: 410,673. Time switches. GARCIA, E. V., 7, Calle de San Antonio, Lerida, Spain. Sept. 30, 1933, No. 26945. Convention date, Oct. 5, 1932. [Class 38 (v).] At a time deter mined by the setting of an indicator 14 a spring-pressed cam wheel 8 which bears against a pin 23 on e shaft 20 rotated by clockwork, moves tc the left carrying with it a wheel 21 and a lever 3 the lower end of which then makes contact with the end of an arm 5. As the shaft 20 continues tc rotate the lever 3 which is flexible moves slowly back towards its dotted line position and eventually breaks contact with the arm 5. The time at which this occurs is regulated by initial rotation of the arm 5 by means of a knob 6, which causes the end of the arm 5 to approach or recede from the lever 3. The lever 3 carries a sleeve 2 which embraces the hub of the wheel 21 so as to follow the axial movements of the wheel. The initial position of the cam wheel 8 is adjusted by means of the indicator 14 which turns a wheel 19 gearing with the wheel 21 carrying the cam wheel.

Title: Improvements in three phase electric switches or contactors
IPC: H01H9/56
Filed: 1950-11-04
Abstract: 671,999. Electromagnetic switches. BROOKE, W., and BALDWIN, H. T. Nov. 4, 1950. No. 26986/50. Class 38 (v). To reduce the possibility of failure of a.threephase switch, particularly an electromagnetically-operated, gravity-controlled switch, due to welding of the contacts, one pair of contacts are arranged to close substantially in advance of the other two pairs and open substantially after the other two pairs so that the spring biassing the moving contact of the "advanced" pair of contacts assists in obtaining a quick break at the other two pairs. When the switch is used in three-wire, three-phase circuit, the current is. not interrupted by the "advanced" contacts but only by the other two pairs of contacts, so that should the switch be tilted to a point where gravity will not open. it. the spring biassing the "advanced" moving contact is able to open the other two pairs of contacts to interrupt the supply without the welding of the contacts. In the figure, the switch has three fixed contacts D, E, F pivotally mounted on. a common operating shaft G and biassed by springs M, N, P. An armature L secured to the shaft G may be attracted by an electromagnet K against the gravitational forces acting on the moving switch parts. The gap between the contacts B and E is smaller than that between the other pairs of contacts so that when the electromagnet is energized the contacts B, E close first and the spring N is more fully compressed than the springs M, P when the switch is closed. This enables the spring N to apply an opening force for the separation of the contacts A, D and C, F when the electromagnet K is de-energized. The switch may be provided with magnetic blow-out devices.

Title: Filling valve assembly for a liquefied gas lighter
IPC: F23Q2/52
Filed: 1962-07-13
Abstract: 970,282. Valves. T. IKETANI. July 13, 1962 [Jan. 11, 1962], No. 27060/62. Heading F2V. [Also in Division F4] The filling valve of a liquefied gas lighter is provided with a cap 15 which is manually screwed into the body 2 of the valve, after filling, and temporarily opens the valve. The cap 15 has a cavity 19 with a vent hole 21 and a threaded bore 20 to receive a threaded portion 12 of a vertically movable valve element 3. The interengaging threads of the cap 15 and body 2 have a coarser pitch than the interengaging threads of the cap 15 and the element 3, such that as the cap is screwed down, the element is screwed up into the cavity 19 and hence the valve is opened. When however the threaded portion 12 passes freely into the cavity 19, a coil spring 5 urges the element 3 into the closed position. The valve element 3 has a top needle portion 7 and a bottom necked portion 9 in which is formed a valve port 8 in communication with an axial filling passage 11. A resilient packing 6 interposed between a shoulder 10 in the valve body 2 and a cage 4 secured to the body 2 fits on the necked portion 9 to close the valve port 8. This packing is deformed upon depression of the valve element 3 and opens the port 8 to the interior of the fuel tank. A conical surface on the shoulder 10 allows the packing 6 and the valve element 3 to be displaced upwards as the cap is removed from the cavity 19. In a further embodiment, Fig. 4 (not shown), an apertured resilient packing is secured to the cap to replace the threaded bore and a head portion on the valve element replaces the threaded portion.

Title: Improved apparatus for controlling the supply of liquids to bottles, vessels, jars and like containers
IPC: B67D1/12
Filed: 1929-09-07
Abstract: 343,425. Automatic-feed weighers. ROBERTS, T., 33, Deane Road, Bolton. Sept. 7, 1929, No. 27227. [Class 143.] Relates to the type of apparatus for delivering a predetermined weight of liquid &c. into a jar, can, &c., balanced on the scale of a weighing machine, in which the delivery action is started by an attendant manually operating a lever to open the inlet valve, the valve being maintained in its open position until the predetermined weight of liquid &c. has been run in, when the valve is automatically closed. The apparatus is controlled either by evacuation, pressure or hydraulic means. Fig. 8 shows the general lay-out of the machine working on the evacuation principle. The suction means A withdraws air from the connections a, A<2> and cylinders b, b<1>, Fig. 1. The attendant depresses lever h, pivoted at h<3>, which opens valve S to allow liquid &c. from tank B to flow into the receptacle C balanced on the scale pan 12 of the weighing machine. The other end of lever h is maintained in its raised position by valves c, c<1> being drawn by suction on to their cylinder heads and pushing the projection g of rod f under the slope h<1> of lever h. When the predetermined weight has been run in the arm 15 is raised, and by a projection 15<a> opens valve K, aided by a weight, to break instantly the vacuum, the entering air raising the flexible diaphragm t<1> to open valve u. This allows the spring s<4> to overcome the spring g<1> and valve s is closed. A modification of the working parts connected with the cylinders b, b<1> and maintaining the lever h in the raised position consists of a rocker with a spring-loaded lever the latter being controlled by the rod f, Fig. 1. A further modification for use under evacuated conditions, Fig. 5, consists of a piston c<10> sliding in a cylinder 20. The lever h being depressed opens the valve S, as before, and the suction in cylinder 20 retains the lever in this position. When the predetermined weight has been run in the projection 15<a> rises to open valve k which by means of diaphragm t<1> and valve u breaks the vacuum. The piston c<10> being released the valve S closes under the action of the spring S<4>. For use under pressure or hydraulic means the construction in Fig. 7 has a valve m rotatable in seating m3 the pressure fluid entering the centre of the valve and capable of actuating the piston c<3> when one of the ports 2 crosses the end of pipe a<7>. The valve m is rotated by a ratchet wheel m<1> driven by a pawl m<2> from a lever system p, p<1>, the latter being connected with the lever h. When the latter is depressed the valve m is moved, a port 2 crossing the pipe a7 to allow pressure medium to enter the cylinder b2 and force piston c<3>, rod f and projection g to retain lever h in the raised position. When the predetermined weight has been run in the valve k is raised and the pressure released, the piston &c. returning under the spring action and the valve closing.

Abstract: 1,119,199. Moulding machines; feeding plastics materials. PROCESS DEVELOPMENTS Ltd. 20 June, 1966, No. 27457/66. Heading B5A. In a device for feeding additives such as stabilizers, colouring or anti-static materials to thermoplastics processing machinery, e.g. extrusion, injection or blow moulding machines, a strand 24 of the material is fed between a knurled capstan 15 driven by motor 14 and a roller 19, through a position-adjustable guide tube 25 and thence to co-operating knives 2 and 6 which slice the strand into pieces of required size. These pieces travel to the processing machine via a funnel (52), Figs. 1 and 2 (not shown), and may be led either through the hopper which contains the bulk of the material to be processed or directly to an inlet in the machine barrel or cylinder. Knife 2 may be one of a number attached to rotary cutter 1 and a number of anvils, 5, only one shown, each of which support a knife 6, may be provided together with associated feed mechanism 15, 19 secured around a circular base-plate 7. The clearance between knives 2 and 6, e.g. 0À004 inch, is adjustable by rotation of an eccentric sleeve 12 whose end projects through a slot 13 in anvil 5. Guide tube 25 is biased by a spring 28 attached to the anvil against the end of an adjustable screw (33), Figs. 1 and 2 (not shown). When several anvils are used it is preferred to guide each strand 24 to a different point along the vertically disposed length of knife 6. Fig. 7 (not reproduced), shows the mounting of blade 6 which is held within a slot by a grub-screw (40) bearing on a disc-spring (41). Furthermore, a pressure pad (37) may be provided to prevent backlash between anvil 5 and sleeve 12. Figs. 4 and 5 (not reproduced), show an alternative cutter 1 where blades (44) are supported between side-plates (45) biased against pins (48) by springs (50). Instead of strip feed by capstan 15, feeding may be accomplished by means of a reciprocating chuck. A visual or audio alarm may be actuated when there is no strand between capstan 15 and roller 19 by consequent movement of motor 14, pivoted at 21, against a microswitch 53.

Abstract: 856,738. Electric analog computing. PENLEY, W. H., and GENERAL ELECTRIC CO. Ltd. Oct 29, 1953 [Oct 31, 1952], No. 27513/52. Class 37 A computer for guiding an aircraft I on one of two types of pursuit interception manoeuvre compares (i) the time taken by the target T on its present course to reach a point Q <SP>1</SP> further along that course by a predetermined " inbehind" distance QQ 1 than that point Q at which the interceptor I will fly on to it with (ii) the time taken for the interceptor I to reach this point Q. With 'the simple manoeuvre, Fig. 2, the interceptor moves from I to P along a line at an angle (# I  1-# T ) to the target course and then along an arc PQ of minimum flying radius r. If the interceptor is already too close to the course of the target, it crosses this course, following two arcs IP and PQ, both of radius r, the second arc subtending an angle #, Fig. 3. The " in-behind distance c is applied at P 20  and T 7 , the minimum flying radius r at P 3  and Ts, and the target velocity V T  and heading # T  adjusted to align the target marker spot on the echo on a P.P.I. display. North and east components (N I ,E I ) of the interceptor's velocity are applied at T 1 , T 2 . When a switch S 1  is closed, a relay X closes contacts X  1 . . . X 4 and a clutch EC is energized. Outputs -6=N T -N I ) cos# T  + (E T -E I )sin# T  and a=(E T -EI) cos # T - (N T -N I ) sin# T  are produced at T 3,T 4 and at T  5 , T  6  by multiplying elapsed time at P  1  by V T  at P 2  and then by cos# T  and sin # T  at SCP  1 , to produce N T , E T , adding the integrals -N I , -E I  of N<SP>I</SP>, E<SP>I</SP> at the inputs to amplifiers A  4 , A  5  providing four outputs from sine-cosine potentiometers SCP 2 , SCP  3  representing the four terms of a and -b. A resolver R M  1  controls the three sine-cosine potentiometers SCP 1  ....  3  according to # T . Outputs of cos # T , sin # T  at T 13 , T 12  control the target marker spot and one of two sets of resistors R 2 , R 3  is used according to the P.P.I. range employed. Referring to Fig. 5, a relay Y operates according to the sign of a to provide lal at Y 1  and # I -#T on the shaft of a resolver RM 2 . The term |a|- r = rcos(# I -# T ) as part of the simple tan(# I -# T ) manoeuvre, is obtained by adding the terms of the numerator at the input to amplifier A i o and dividing with a feedback of -sin(#I-# T ), the output being multiplied by cos(# I -# T ). When lal<r-cos(# I -# T ), a diode V1 conducts and voltages from A 10  are suppressed as the terms derived therefrom are not required for the crossing-course manoeuvre. Similarly the terms - 2rsin# and 2# are suppressed by one part or the other of a double-diode V  3  unless 0‹ < # < 90‹, see Fig. 3. The (# I -# T ) shaft of there solver RM2 is driven by a motor M  1  until a balance is achieved wheninterceptor course is then indicated by outputs of cos# I <SP>1</SP>, sin# I 1 at T 16 , T 17 .
