Title: Rivet inserting machine
IPC: B21J15/32
Filed: 1952-05-09
Abstract: 740,749. Riveting. KELSEY-HAYES WHEEL CO. May 9, 1952 [July 18, 1951], No. 11817/52. Classes 83 (2) and 83 (4). [Also in Group XXX] Making wheels.-Means for automatically inserting rivets in preassembled work is described with reference to the manufacture of wheels. A spider and rim assembly are supported on a table 1 and located by a pin 2 that enters one of the bolt holes for securing the spider to the hub. Rivets are supplied from a magazine 29 fitted with an escapement having fingers 30, 31, Fig. 7, carried by a bar 33 having a cam slot 34 engaged by a pin 35, Fig. 3, on a reciprocating push-rod 7. Rivets are separated from the stack and allowed to fall singly through a shaped opening in a tubular holder 6 surrounding the push-rod and terminating in three resilient jaws 14. The pushrod is connected to a piston-rod 19 of a pneumatic cylinder 20 and transmits movement to the right in Fig. 3, through a spring 24 to the holder 6. The rod and holder are further connected by a pin-and-slot 22 that permits a limited amount of lost motion but ensures positive retraction from the fully advanced position. The holder is prevented from rotating by a fixed key 17 engaging a slot 16. Operation. When the push-rod 7 is retracted by the pneumatic cylinder 20, the bar 33 is rocked to allow a rivet to drop into the holder 6. On the next forward stroke of the push-rod the holder is advanced with it by the spring 24 until the holder engages the work W, after which the rod 7 advances further to push the rivet out of the spring fingers 14 of the holder and insert it in a hole in the work. If the rivet should remain in the holder, due to misalignment of the work &c., the rivet is positively ejected from the holder on the return stroke by a pivoted finger 44 which drops through a slot in the holder during the advance of the latter and lies behind the rivet head. The finger 44 is free to swing upwards over the rivet, as shown dotted in Fig. 3, during advance of the holder. Specification 740,741 is referred to.

Patent GB-639565-A (GB)
Title: Improvements in or relating to pulse producing in radio-pulse transmitter systems
IPC: G01S1/24
Filed: 1947-05-05
Abstract: 639,565. Pulsing carrier frequencies. RADIO CORPORATION OF AMERICA. May 5,1947, No. 12134. Convention date, June 10, 1946. [Class 40 (v)] [Also in Group XL (b)] Carrier wave pulses of low power are amplified and clipped to form high-power pulses of rectangular carrier which are passed to an aerial without further amplification through a bandpass filter network to produce an envelope of predetermined shape. In this way the shape of the pulse envelope is independent of changes in valve voltages or of valve replacements, rendering the pulsing system suitable for certain types of radio navigational or position-determining systems. As shown in Fig. 2, the carrier is fed to the inner grid of a valve 19, which is normally blocked by negative voltage on its middle grid but is rendered operative by recurrent positive pulses applied through a capacity 37 and across a diode 38 and resistor 39. The pulses of carrier output are amplified and clipped at 28 to produce pulses of rectangular carrier 29 of high power. These are passed through a transformer 46, band-pass filter 31 and coaxial line 51 to the radiating aerial; whilst a low-pass filter 32 and high-pass filter 33 each terminating in a resistor R1, R2 are connected in shunt to the band-pass filter 31. The effect of the filters is to produce a rounded pulse envelope 34 as shown in Fig. 5. The limits of the bandpass filter 31 may be 10 kc/s on either side of the carrier frequency, and these limits are also the respective cut-off frequencies of the filters 32, 33. The Specification states the electrical dimensions of the filter elements. Both the carrier frequency and the pulse recurrence frequency may be derived from a single master oscillator.

Patent GB-1205843-A (GB)
Title: A filling device for filling the magazine of a machine manipulating cigarettes
IPC: A24C5/356
Filed: 1968-03-13
Abstract: 1,205,843. Feeding cigarettes. HAUNI-WERKE KORBER & CO. K.G. 13 March, 1968 [21 June, 1967], No. 12184/68. Heading B8S. Trays of cigarettes 9 on platform 6 are fed to magazine 4 by frame 14 and the empty trays 9 are dropped down on to platform 7 for discharge. Each tray is placed in frame 14 being secured therein by flaps 26 and 27, the frame being reciprocable along shaft 17 and pivotable thereon so that the frame receives the tray in its right-hand position and moves leftwards into the position shown in Fig. 1 at which the frame together with tray pivots upwardly into a position vertically over the hopper 4 as shown in Fig. 3. The space between the now-vertical frame 14 and the magazine 4 is taken up by flexible walls 41, 42, 43 which are rolled upon and extend from shafts 41a, 42a, 43a. The upper part of the flexible walls is carried by frame 46 which itself is carried by rods 47, 48 moving in fixed guides 51, 52. The position of frame 46 is governed by a level device formed by source 63 and sensor 64 and carried by the frame. When the level of the cigarettes falls blow that of the source 63 the sensor 64 operates to energize motor 57 which drives frame 46 via pinion 58 and rack 59 fixed to bar 49 forming part of the frame 46. Accordingly frame 46 together with flexible walls 41, 42, 43 move upwards and as the cigarettes fall downwards (cover 36 having been removed from tray 9) the frame 46 engages and pushes upwards the tray 9 which empties its cigarettes. Frame plus tray moves upwards until the tray is completely empty. The level of cigarettes continues to fall and when it falls to the level where sensor 63 now in its upper position operates, two things happen. Firstly frame 14 together with tray 9 pivots downwardly and rightwardly, into the position shown in Fig. 1, the tray being pressed downwards in this movement by fixed guide 66. Additionally the motor 57 is reversed and the frame 46 descends to its lowermost position. Cigarettes then fall again below the level of source 63 and operate motor 57 to recommence the cycle. The empty tray is deposited by frame 14 into drop box 13.

Title: System of distant electric control by synchronised distributors
IPC: H04Q9/04
Filed: 1928-04-26
Abstract: 289,443. Blondel, A. April 27, 1927, [Convention date]. Synchronous movements. - In a remote control system employing synchronized rotating members at the transmitter and receiver the arrangement is such that short impulses are sent and repeated periodically and distributed by the receiving member to relays controlling a motor or the like. Fig. 1 shows insulating discs 1, 2 carrying brushes 3, 4 connected to slip rings 5, 6, and rotated by synchronous motors 23, 24. The brushes rub on members 11, 12, which can be moved mechanically or by hand to adjust angularly the position of contacts 13, 14 to determine the point at which impulses are sent from the sources 9, 10. The receiving station comprises discs 1<1>, 2<1> and brushes 3', 4', driven by synchronous motors 23<1>, 24' co-operat- 11<1>. 12<1> and connected to relays 32a - - 32f and 32<1>a - - 32<1>f respectively. Narrow segments 31<a>, 31<1a> may be provided for svnchronizing and the motors 24. 24<1> may be dispensed with, the second discs 2, 2<1> being driven through gearing 26 - - 29. Fig. 3 shows control members 11, 12 and controlled member 39 and a differential gear 54 controlled by a motor 56 for correcting synchronism. Alternatively an electrical differential may be employed constituted by motors with relative phase displacement between the stator and rotor adjusted either by varying the phase of the supply or by displacing the stator which is mounted in bearings. Primary or a secondary control of synchronism may be effected by tele-motors. Reference has been directed by the Comptroller to Specification 245,135, [Class 40 (i), Electric signalling systems &c.].
Patent GB-162621-A (GB)
Title: Synchronising systems particularly applicable to printing telegraphs
IPC: H04L7/00
Filed: 1921-04-29
Abstract: 162,621. Western Electric Co., Ltd., (Assignees of Bell, J. H.). May 1, 1920, [Convention date]. Synchronous movements and synchronism indicators.-Synchronism indicators, particularly for use with printing telegraphs, are arranged to give indication of the relative phase displacement of distributors at the sending and receiving stations. The diagram shows the equipment of a receiving station to which impulses come over the line L from a pace-setting sending station. A phonic or other synchronous motor 30 drives the shaft 31 carrying brush-contact arms of three distributors C, R, S. Distributor S is for sending purposes by a keyboard or other transmitter T, only one being shown. The contact segments of receiving distributor R are normally connected to the selecting magnets of printers P, through a switch device 35, 56, by which, for testing purposes, the printers are disconnected, and the segments connected to corresponding lamps 1 - - 20 of a synchronism indicator. Distributors R, S have each a pointer 34 whereby the ring and segmental contacts can be angularly adjusted with respect to the brush contacts. The pace-setting -station sends repeatedly a single positive impulse followed by four negative impulses. The positive impulse operates polarized relay 50 to connect a battery 52 through distributor R and switch 35, 56 to one of the indicator lamps, which is thereby lighted, the particular lamp depending upon the segmental contact on which the distributor brush happens to be at the time. Intermittent illumination thus occurs, and if the distributors at the pace-setting and receiving station are isochronous, the illumination is confined to one lamp. If not, the illumination travels over the bank of lamps. By prearrangement, the positive impulse is sent so that if the distributors at the pace-setting and receiving stations are in phase, some predetermined lamp, say 1, should be intermittingly illuminated. If some other lamp, say 5, is found to be illuminated, angular adjustment of the segmental distributor contacts is made by means of pointer 34 to bring the illumination to lamp 1. The distributors are then in phase, and switch 35, 56 is thrown to disconnect the indicator, and connect the printers P. Distributor C controls local circuits such as those of tape-feeding magnets of the transmitters T, or of printing magnets of printers P.

Title: Improvements in pressure-sensitive regulator devices
IPC: F02D1/00
Filed: 1937-04-30
Abstract: 479,988. Regulating. DAIMLERBENZ AKT.-GES. April 30, 1937, No. 12352. Convention date, May 4, 1936. [Class 7 (vi)] Pressure -sensitive capsules, particularly for controlling aircraft engines, are so adjusted and coupled to the device for regulating the .richness of the mixture that, in the event of equalization of the pressures inside and outside the capsule due to a leak, the capsule influences the regulating - device to assume a position which is a mean between the two extreme positions of adjustment. The Figure shows a capsule 1 connected to an air - controlling throttle 8 and provided with an air-venting screw 10 whereby the internal and external pressures may be equalized when the aircraft is in the vicinity of the ground. The screw is then closed, and when the aircraft rises, the capsule adjusts the throttle to give a weaker mixture. If a leakage occurs in the capsule when the aircraft is at a considerable altitude, the throttle assumes the normal or ground-level position, which, although giving too rich a mixture for the altitude, will prevent the dangerous condition arising of too poor a mixture when the aircraft descends to lower levels. In a modification, the capsule is given an initial amount of expansion by means of a screw stop in its normal position. Again, the base of the capsule, instead of being fixed, may be connected to a temperature-sensitive capsule.
