Title: Improvements in or relating to regulating systems for dynamo electric machines
IPC: B60L9/04
Filed: 1928-03-20
Abstract: 313,665. Filmer, C., and Associated Electrical Industries, Ltd. March 20, 1928. Motor-generators. - The generator of a motorgenerator set particularly for use in electric traction systems has both series and separate excitation, and field control means are provided for varying simultaneously the motor speed and the generator excitation so as to maintain the generator voltage characteristic substantially unaltered at varying speeds of the set. The characteristic of the generator is defined by a set of curves each connecting generator voltage and generator load at a particular value of the supply voltage or other variable feature such as motor field connections. The motor 1 driving the generator 2 has a series field winding in two parts 7, 8, and the generator has a field winding 9 in series with the motor, and a compounding winding 10 in series with its own load. In addition to driving the generator for supplying power for control circuits, train lighting and supplying exciting current for the axle-driven exciters used during regenerative braking, for example as described in Specification 313,427, [Class 38 (iii), Electric motor control systems &c.], the motor may be used to drive an exhauster 4 for the brakes. To release the brakes, the speed of the exhauster is increased by short-circuiting the part 8 of the motor series field winding by means of the switch 12 which also short-circuits a part 11 of the generator field winding 9 whereby the excitation of the generator is reduced to compensate for the increase of speed. In order to compensate for variation in the point of operation in the saturation curve of the generator with variation in speed, a second switch 14 interlocked with the switch 12 is arranged to short-circuit a part 13 of the generator compounding winding 10. The brake control lever may be arranged to operate the motor field control means.

Title: Pushbutton keyboard code generating arrangements
IPC: B41J7/30
Filed: 1971-04-02
Abstract: 1385902 Keyboards having coded outputs PLESSEY CO Ltd 11 April 1972 [2 April 1971] 8547/71 Heading G4H In a keyboard code-generating arrangement wherein a strobe output (" valid code ") signal ST is produced when the output OP of an m-bit oscillator-driven cycling counter EC is found by a comparison circuit K to correspond with a selected key, rollover protection is afforded by the presence of a 2<SP>m</SP> stage shift register (or store performing the same function) also driven by the oscillator, and a gate G which ensure that one and only one signal ST occurs for each key selection, irrespective of the number of cycles of counter EC. Depression of a key closes a connection in circuit K (which may include a binary to decimal converter) and produces an output when the counter output first corresponds to the key selected; this output is fed into the first stage of SR, and also through gate G to trigger a monostable M which produces signal ST and temporarily inhibits oscillator OS. If the key is still depressed when the output OP again corresponds to the selected key, then counter EC will have been shifted 2<SP>m</SP> times; however, so too will SR, so that the first output from K will be shifted out via an inverter to close gate G, thus preventing the second output from K from triggering the monostable M.

Title: Improvements in apparatus for the measurement of quantities related to the dimensions of visual impressions
IPC: G01N3/42
Filed: 1941-07-10
Abstract: 549,029. Calculating device for measuring hardeners of materials &c. VICKERS-ARMSTRONGS; Ltd., CLIFTON, J. C., and RABARTS, F. W. July 10, 1941, No. 8682. [Class 106 (i)] Means for evaluating a quantity such as hardness related to a linear dimension of an impression, mark &c. comprises a number of elements movable relatively to one another and to a fixed datum each being inscribed with a scale of values of one or more of the. variables involved and one being adapted to measure the dimension. A circular transparent disc 1 is inscribed with logarithmic scales of load and hardness values shown in full lines in Fig. 4 and a transparent disc 2 is inscribed with a double-sided equiangular logarithmic spiral 3 symmetrically disposed about a circumference passed through the centre line of the impression and shown in dotted lines, Fig. 4. This spiral is formed by laying out the greatest and least values of the dimension over the range on any radius. Intermediate values are laid down radially with the angles proportional to the logarithms of these values. The datum line intersects normally with the common axis of the discs and the normal to the impression. The disc 1 is mounted on a shaft 4 which carries at its other end a magnification indicator 5 and a knurled knob 6. The disc 2 is mounted on a sleeve 7 loose on the shaft 4 and carrying a load scale 8. The discs may be locked in co-operation with a spring 10 and the discs then rotated together. A magnified image of the impression 12 on the test piece 11 is produced by a microscope objective 13, a vertical illuminator 14, a projection lens 15 and a condenser 16. This image is projected on to a viewing screen 17 by a projection ocular 18 and a prism 19. The optical system for the relevant part of the hardener scale consists of a lamp 21, condenser 22, lens 23 and prism 24. The load and magnification being known, the discs 1 and 2 are suitably coupled and both rotated until the image of the impression is callipered in the spiral 3, shown in dotted lines, Fig. 4 as the diagonal of an impression of a pyramid indentor. The hardness can then be read off at the diametrically opposed position or on the screen 20.

Title: Variable speed control device
IPC: H02P29/00
Filed: 1961-03-10
Abstract: 928,826. Variable speed gear and control; clutch control. O. KRUMMEL. March 10, 1961 [March 21, 1960], No. 8784/61. Class 80 (2). A continuously variable speed gear comprises a massive clutch driving member 4 intermittently axially displaced to engage a clutch driven member 5 by an electromagnet 3 controlled by a microswitch 9 by an electromagnet 3 controlled by a microswitch 9 actuated by a variable centrifugal governor to provide a substantially constant predetermined output speed. As shown, the member 4 is an armature journalled in rotatable pole members 3, 5 respectively fast on an input electric motor shaft 2 and an output shaft 5c. A variable centrifugal governor 8, output shaft driven through gears 6, 7, energizes and de-energizes, through a blade 9c and contacts 9b, 9a of the microswitch 9 and slip rings, respectively, the windings of the pole members 5, 3 when the output speed falls below a predetermined level, and vice versa. For starting, assuming the motor to be running, and the output shaft stationary so that the blade 9c engages the contact 9b and the pole member 5 attracts the member 4, a manual switch 11 is closed, whereby the winding of the pole member 3 is energized for a short period sufficient to rotate the member 4 and hence the pole member 5 and the output shaft until the latter reaches the desired speed, whereupon the governor actuates the microswitch to energize the winding of the pole member 3 independently of the switch 11 which can now be opened, and to de-energize the winding of the pole member 5. In Fig. 2 (not shown), the pole member 3 is dispensed with, the member 4 being splined of the input shaft and spring-urged to disengage from the driven shaft pole member.

Title: Improvements in Self-fitting and Ventilating Means for Hats and the like.
IPC: A42C5/04
Filed: 1916-06-23
Abstract: 103,425. Hawkes & Co., and Bensley, W. C. June 23, 1916. Helmets; ventilating.- For fitting and ventilating purposes, the inner band b of a hat or helmet, supporting the leather c, is connected by rubberjacketed tongues f to a ring h, which fits the outer shell and is connected to it by lugs k and crown bands n, or by either of them alone. The chief feature of the invention consists in connecting the ring tongues and band by rivets e, g so as to form a uniting structure. A cork or like packing-strip i is used between the ring and shell to absorb shocks. The tongues may be of inverted U-formation, and each is preferably in a vertical plane. In a modification, the bands n are shortened, and their looped ends are laced to a central crown fitting. In either case, the bands form a resilient false crown, against which the head of the wearer bears through the lining d.
Patent GB-199172-A (GB)
Title: Improvements in the springing of motor vehicles
IPC: B60G15/06
Filed: 1922-03-28
Abstract: 199,172. North, O. D. March 28, 1922. Dash-pots and fluid-friction vibration-dampers.-The oscillations of a vehicle on its springs are damped by displacement of fluid which is caused by pistons or vanes connected to the axles or wheel-carrying members to pass through an orifice controlled by a spring-balanced member which practically closes the orifice in the normal position, but is able to pass therethrough without making contact with the sides; alternatively, the orifice may be in the spring-balanced member. In one form of the invention, a shaft 6, Fig. 2, passing into an oilfilled chamber 8 on the chassis 9 is connected to the axle by a lever arm 5. A pinion 10 on the shaft engages a rack 11 attached to a hollow piston-rod 12 of a piston 13 moving in a cylinder 14 and pressed by a strong spring 15. Slidably mounted on a rod 19 secured within the rod 12 is a disc member 20 normally held by springs 21, 22 within an orifice 26<a> in a projecting ring 26 on the piston rod 12. On upward movement of the axle, the piston 13 is moved against the spring 15 and causes oil to pass through ports 18 into the piston rod and move the member 20 to the left against the spring 21, thus allowing oil to pass through the orifice 26<a>. If the fluid becomes more viscid, the member 20 moves farther to allow a freer passage. On downward movement of the axle, the member 20 passes through the orifice against the spring 22, and, if the downward movement is great, the rod 12 encounters a spring buffer 16. By suitably shaping the surfaces a, b of the member 20 and the surfaces c, d of the piston-rod bore adjacent the ring 26, the resistance in either direction may be varied. In a modified form, the member 20 is replaced by a spring-balanced piston slidable between two sets of ports in a tube communicating with the fluid displaced by the piston or vane. In another form, the control member 51, Fig. 4, is fixed to a rod 50 in a cvlinder 40 and an annular piston 43 is normally held by springs 44, 45 in such a position that the member 51 closes its orifice 47<a>, the displaced fluid entering and leaving the cylinder through ports 41, 42. This form may be modified by connecting the rod 50 to the wheel-carrying member, the composite piston 51, 43 then acting as the fluid-displacing member.

Title: Machine for covering and nailing the heel-breasts of shoes having louis xv heels
IPC: A43D25/12
Filed: 1928-03-24
Abstract: 318,181. Beaugeard, J. March 24, 1928. Loose-nailing.-In a machine for applying heel-breast facings to shoes with Louis heels, the facing is bent into conformity with the shape of the breast and automatically fixed in position by fasteners. The breast flap is held in position by members 35, the rear of the heel being supported by a number of independently slidable plates 29. While thus held, the work is intermittently moved in a path corresponding to the curvature of the heel breast while a succession of pairs of nails are driven by nail drivers 60 reciprocating in a substantially horizontal plane. The work support comprises a last pin 19 adjustable angularly and longitudinally of the machine, and an adjustable toe-rest 24. The members 35 are adjustable towards and away from each other by inclined slots 40 in a vertically adjustable plate 41. The members can slide along but rotate with a spindle 45 on which is a ratchet wheel 46 cooperating with a pawl for maintaining the facing pressed against the heel. This mechanism is carried bv slides 34 adjustable longitudinally of the machine by ramps 48 and maintained in operative position by pivoted spring pressed stops 36. The plates 29, after being caused to engage the rear of the heel, are clamped in position by a bolt 31. The heel holding mechanism is adjustable longitudinally of the machine by a hand wheel 27. The whole work support is mounted on a member 10 formed with curved slots 9, 11 respectively engaging pins 8, 12 on supports 2, 3 adjustable longitudinally of the machine by a cam 4. To cause the work to be intermittently moved between the insertions of successive pairs of fasteners, the member 10 is secured to one end of a chain 101 secured to a rack formed with teeth 98 normally engaged by a pin 103 on a double lever 95 oscillated by an eccentric 90. On the work support reaching the end of its travel, pins 105 on the rack engage slides 106 and depress the pin 103 so that it is below the teeth 98. The pair of nail containers 72 each have false bottoms 71 jerked upwardly by pins 70 and cam slots 69 moving with the hammers. The upward jerk throws nails on to a trough 73 leading to a raceway 77 at the end of which is a separator 78 urged by a spring 79 against a member 80 lifted by a cam 82 on a shaft 83 moving with the hammer. As the member 80 is lifted, a recess therein allows the separator to operate, and simultaneously, a groove in the member 80 moves into alignment with the raceway. Also simultaneously, a pivoted stop 86 is lifted to allow the nail to drop down the nail guide. This mechanism is actuated by an eccentric 64. The hammers are spring-pressed towards each other, the tubes in which the driver bars 67 reciprocate being guided by the members 35. These tubes carry projections 59 which shape the leather on the outer edges of the heel.
