IPC: H02K47/00
Filed: 1920-08-04
Abstract: 170,965. Glaser, W. H., and Glaser, Ltd., W. H. Aug. 4, 1920. Commutator switching-arrangements.-A combination of apparatus designed to furnish direct current and motive power when connected either to alternating or direct current mains comprises a synchronous motor 14 which will lock in a definite position when supplied with direct current, coupled to a rectifying commutator 24 and a second motor 10 to yield the motive power. If the synchronous motor is not self-starting the second motor is a series machine which will run equally well on alternating or direct current; it is connected in parallel with the synchronous motor and drives it up to synchronism through a slipping coupling as shown in Fig. 1. If a self starting synchronous motor is used the power motor is a direct current machine connected in parallel with the rectifying commutator 24. In both cases if the terminals 28, 29 are connected to direct current mains the synchronous motor is held stationary in such a position that current passes through the commutator to the current consuming devices and the second motor furnishes motive power. The apparatus is preferably used with that described in Specification 172,055 [Class 37, Electricity, Measuring &c.], so that it may be connected to mains of any voltage.

The different temperatures are measured by thermocouples. Alternatively if the coefficient of expansion of the sample is known the change in its length may be computed from which the difference in temperature may be calculated.

The racks form part of a cross-slide 95 operated by a fluid motor 110. The carriage 70 is supported at one end on a lever 72 reciprocated by a motor-driven cam 56 and at the other end on rollers 76 supported on a non-linear track 75. This track ensures substantial horizontal movement of the bar 14 when the latter is moved by the crank arms. Initially, due to the combined movements of the carriage 70 and of the crank arms 90, 92 the bar 14 follows a diagonal path 16 to move the articles across the conveyer 10 on to a deadplate 20 and then on to the lehr conveyer 22. The bar 14 then retracts horizontally to a position 14a clear of the articles after which a camming device 60 causes the crank arms 90, 92 to be raised to stored positions 90b, 92b such that the bar 14 is clear of articles on the convever 10. The carriage 70 then returns to its starting position with the bar 14 following a lateral course above the articles on the conveyer 10.

Title: Improvement in low-pass network
IPC: H04J1/04
Filed: 1944-11-28
Abstract: 584,769. Low-pass filtering systems. MARCONI'S WIRELESS TELEGRAPH CO. Ltd. Nov. 28, 1944, No. 23737. Convention date, Nov. 29, 1943. [Class 40 (iv)] [Also in Group XL] In a variable cut-off low-pass filtering system, a carrier frequency having side-bands equal to the required band-width is obtained in two stages, by modulating a first variable frequency with the input frequencies, filtering to restrict one side band, and using the resulting frequencies to modulate another variable carrier frequency and filtering to restrict the other side band, the final output being then rectified. By this means fixed band pass filters of simple construction may be utilized. In the filter, Fig. 1, designed to have a cut-off frequency f2, an input band of frequencies 0-f1 modulates a carrier frequency fc1 and the band pa.ss filter 1 restricts the output to frequencies below fc2+f2. The output of filter 1 modulates a higher frequency fc2 and band pass filter 2 restricts the output to frequencies above fc1+fc2-f2, thereby producing a frequency fc1+fc2 with two side bands of width f2 which on detection produces a frequency band 0-f2. The cut-off frequency can be varied by simultaneously varying the frequencies of the oscillators 1 and 2, to restrict both side bands appropriately. The filter networks may also be made adjustable if desired.

Abstract: 857,235. Fifth-wheel couplings. DYSON & CO. Ltd., R. A. July 25, 1958, No. 23951/58. Class 103(5). A fifth wheel coupling comprises jaws 13, 14 pivoted at 15, 16 and adapted to pass through slots in a Vee gap 11c to grip a king pin 12, toggle links 17, 18 pivoted together at 19 and eccentrically pivoted at 17a, 18a to extensions of the jaws, and a block 21 urged against the pivot 19 by a spring 20, which block may be moved upwardly or downwardly through a lost motion linkage 30, 31 by rotating an arm 23 about a pivot 22. The operating handle 24 may be held in an inoperative position, Fig. 3, by a peg entering a hole in a block mounted on the casing, and may be locked in this position by tilting a U-shaped member 28 until portions 28a, Fig. 2, engage the supporting arm 23. To unlock the coupling the member 28 must first be moved to disengage the abutting portions 28a from the arm 23, then the handle 24 must be pivoted about the pin 25 to release the peg from the block on the casing. If now the arm 23 is moved in an anti-clockwise direction it will lift an arm 30 rigid therewith, and through a pin and slot lost motion connection, lift a link 31 which is pivoted to the pin 22 and also to the block 21. The block 21 will then lift, and a spring arrangement 32 pivoted at one end to an arm 34 will be compressed and move a part 33 upwardly until a surface 33b thereon disengages from a toggle bridge 18b. The spring 32 then moves the arm 34 to engage the long finger of the part 33 with the bridge. If the handle 24 is now moved clockwise the surface 33d will engage the bridge and break the toggle. The handle 24 may then be pivoted in the original direction to complete the unlocking movement. Curved plates on the handle 24 indicate by their disclosed or shielded markings whether or not the handle is in an operative position, and jaw return springs 36 and shock absorbers 37, 38 are provided.

[Also in Division F2] A wheel bearing or like reverse drive wrench comprises an air motor 10, Fig. 1, a handle 13 having clockwise and counter clockwise control switches 14, 16 thereon, a clutch assembly 20, and a spanner portion 21. Clutch 20 comprises a housing 23, Fig. 2, having stepped walls 24, 26, Fig. 3, a sleeve 28 keyed to motor shaft 27, a spring 31 seated in a portion 29 of the sleeve, and a bush 32 rotatable in housing 23 and having ears 33 which co-operate with steps 24, 26 on the housing. In operation, a switch 7 is actuated by the operator pressing a plate- 8, switch 14 is depressed, and air motor 10 rotates shaft 27, sleeve 28, and spanner 21, to thus tighten a bearing. Bush 32 is rotated due to the frictional engagement of spring 31 with the bush, until ears 33 abut walls 24, 26. Shaft 27 continues to rotate sleeve 28, and wind up spring 31, until the bearing being tightened stalls motor 10. Switch 16 is depressed, shaft 27 rotates in an anticlockwise direction to thus unscrew the bearing, and spring 31 rotates bush 32 until ears 33 engage the opposite sides of walls 24, 26, the spring locks shaft 27, and motor 10 stalls. In a modification the spring clutch is replaced by a cam clutch 40, Figs. 4, 5 (not shown). Shaft 27 is keyed to wrench drive 41 and the inner race of the clutch is an interference fit on drive 41. The outer race has a key 43 which moves in an arcuate keyway (44) in housing (45). In operation, drive (41) is rotated and carries the inner and outer races in a clockwise direction until the outer race is stopped by key (43) engaging the end of keyway (44). The inner race continues to rotate until the motor stalls. Under counter clockwise movement to unscrew the bearing a required amount, the races rotate together until key (43) engages the opposite end of keyway (44), and the motor again stalls. In a further modification, Figs. 6, 8, the clutch assembly comprises a housing 50, having an end projection 50a, a sleeve 53 rotatable in the housing and having a dog 53a thereon, a cam clutch 63 having its outer race keyed to sleeve 53 at 65, and an end cover 58 having a stop 62 in the form of a pin, the cover being adjustable on the housing so as to vary the position of the pin relative to projection 50a. In operation during clockwise rotation the clutch rotates until dog 53a engages pin 62 and the bearing is tightened. The bearing is loosened during counterclockwise rotation until dog 53a abuts projection 50a and the motor stalls.
