Title: Improvements in or relating to a system for facsimile transmission and reception
IPC: H04N3/08
Filed: 1935-05-10
Abstract: 461,417. Copying telegraphy. PRIESS, W. H. May 10, 1935, No. 27919/36. Convention date, May 11, 1934. Divided out of 461,128. [Class 40 (iii)] [Also in Group XXXVI] Relates to a scanning system for the transmission and reception of facsimile of the type in which the material to be scanned is moved at a uniform speed across a fixed screen and in which a scanning beam reflected from a single oscillating mirror is caused to move transversely of the direction of the material and longitudinally along a slit formed in the screen. According to the invention, the mirror is adapted to be vibrated torsionally through a determined angle and at its natural frequency by electromechanical means. Fig. 1 shows a transmitter in which light from a source 5D passes through a lens 6D on to a mirror 1D carried by a torsionally vibrated rod 1F, the light reflected from the mirror passing through a slit 4D in an opaque screen 3D on to the moving film 2D, the light being subsequently focused by the lens 7D on to a photo-electric cell 8D. A similar scanning system, in synchronism with that at the transmitter, is employed at the receiver, where the light from a suitable source is modulated by a Kerr cell. The film after exposure at the receiver may be passed progressively through its developing, washing, fixing and drying processes and, if desired, a duplicate printing process. Endless rolls of film are preferably employed both at the transmitter and receiver. Fig. 3 shows a means for vibrating the mirror 5B torsionally on its rod 4B. The rod, which is clamped at its lower end, carries at its upper end a shortcircuit conducting loop 2B on which is mounted the mirror. The loop 2B is located between the poles 1B of a permanent or electromagnet and surrounds a stationary magnet core 3B with which are associated the alternating current coils. The natural frequency of vibration of the system 2B, 4B and 5B may be adjusted, e.g. by means of a small weight movably mounted on the rod. The Specification as open to inspection under Sect. 91 comprises also an arrangement in which the mirror is mounted on the free end of a tuned reed adapted to vibrate in the air gap between a pair of magnet pole-pieces. The film at the receiver may be replaced by sensitized paper. This subject-matter does not appear in the Specification as accepted. Reference has been directed by the Comptroller to Specification 356,363.

Title: Improvements relating to traffic controlling apparatus
IPC: B61L5/06
Filed: 1920-10-02
Abstract: 151,948. McKenzie, Holland, & Westinghouse Power Signal Co., (Assignees of Snavely, C. S.). Oct. 2, 1919, [Convention date]. Miniature signals and indicators; hand levers.- The setting of the points A to one or other of their extreme positions reverses the direction of current supplied from battery F to the magnet E, which operates a polarized indicator 24 and a non-polarized locking-armature 7 which locks the spindle 6 of the hand-lever 13, the circuit including a track circuit formed by the track rails 28 adjacent to the points, a snap-action reversing switch G operated by the cam-plate 38 connected to the points, and a resistance 45 which is shunted by contacts 46, 47, 49 in the extreme positions of the points. The inclusion in the circuit of this resistance causes the pointer 24 to assume a mid-position, but the armature 7 is not released. A train on the rails 28 de-energizes the magnet E and the armature 7 then looks the spindle 6. The switch G is operated by the bar 43 under the action of springs 42, 42a fitted in the yoke in the bar 43 and engaging a bar 40a which is moved by the cam-plate 38. The bar 44, movable with the camplate, has a projection 44a which engages a projection 43a on the bar 43 except in the extreme positions of the bar 44, and thus allows the bar 40a to compress one or other of the springs 42, 42a until the movement of the cam-plate is completed. The compressed spring then reverses the switch G. The pointer 24 of the indicator is mounted on a long horse-shoe magnet P, the poles of which move between the poles of the magnet E.

Title: Improvements in and relating to laundry ironing machines
IPC: D06F65/08
Filed: 1945-10-26
Abstract: 602,205. Ironing-machines. MACHINEFABRIEK REINEVELD N. V. Oct. 26, 1945, No. 28390. Convention date, Sept. 17, 1943. [Class 138(ii)] Relates to a laundry ironing-machine of the type in which each of the end bearings 7 of a clothcovered roller 4, which is rotatably supported in a stationary heated bed 3, is movable in a guideway 8 and is associated with a resilient telescopic rod for lifting the roller from the bed in the form of two members 10, 11 with an interposed spring 16, one member 11 being directly connected to the actuating gear of the lifting device and provided with an abutment 17 normally engaging the second member 10. According to the invention, means are provided for actuating a signal or restoring normal conditions whenever the abutement 17 fails to exercise pressure on the member 10. The member 10 is pivoted to the bearing 7 and is in the form of a strap in which the member 11 is guided. The spring 16 engages between a nut 15 on the upper end of the member 11 and the lower end of the strap. The lower end of the member 11 is rotatably mounted on the pin 12 of a crank which is mounted on a longitudinal shaft extending beneath, and lengthwise of the bed 3. The abutment 17 on the member 11 is provided with a projection, and secured to the strap is a contact box 19 comprising a spring-loaded pin 20 which exerts pressure on the projection when the abutment 17 engages the strap 10. Should the axis of the roller 4 become out of parallel with the bed 3, the strap 10 at one end of the roller is disengaged from the abutment 17 so that the pin 20 opens or closes an electric circuit for operating an acoustic or other signal. The signal' may be replaced by a motor which is controlled by the plungers at opposite ends of the machine so that, when the strap at one end of the machine is disengaged from its abutment, the motor drives through gearing the longitudinal shaft so as to re-align the roller. Alternatively, both the electric signalling device and the motor may be replaced by any suitable pneumatic, hydraulic or mechanical means. If desired the failure of the abutment 17 to exercise pressure on the member 10, may both actuate a signal and operate the device for restoring normal conditions. When the end bearings are mounted in circular guideways, the roller is carried by substantially horizontal arms, with one end of each arm hinged to the frame and the other end engaging the corresponding bearing so that the roller when lifted from its bed, follows an arcuate path.

Title: Improvements in the braking of gravity driven machines
IPC: H02P3/18
Filed: 1932-10-13
Abstract: 399,656. Brakes ; control of A.C. motors ; driving dynamos. ENGLISH ELECTRIC CO., Ltd., 28, Kingsway, London, and KIRKWOOD, J., Thendon, Radford Bank, Stafford. Oct. 13, 1932, No. 28599. [Class 103 (i).] A brake for a gravity-driven hauling or like machine comprises a regenerative polyphase asynchronous dynamo-electric machine mechanically coupled to a speed responsive frictional braking device adapted to be brought into action by its speed responsive means when the speed exceeds some predetermined value above the synchronous speed of the machine, and then to apply over a range of speeds a braking torque which is a direct function of the speed. Gearing 2 connects hauling sheaves 1 to a shaft 3 coupled to the brake 5 and to the machine 4 which is connected to a generating station 7 through a circuit-breaker 9 with overload release coils 10 and a no-volt release coil 11. The haulage system may be set in motion by the machine 4 acting as a motor drawing power from the station 7, a resistance 6 connected to the sliprings of the machine being inserted during starting and gradually cut out. Regenerative braking is obtained when the load on the haulage system drives the machine above its synchronous speed, the machine then generating power to the station 7. This braking may be regulated by the reinsertion of part of the resistance 6. If the station 7 fails or the circuit-breaker 9 is tripped, regenerative braking ceases and the consequent rise in speed causes a centrifugal governor 12 or like speed-responsive device to bring the brake into action by opening the inlet valve 13 and closing the outlet from the brake to the cooler 15. Normally when the inlet is closed and the outlet is open water drains to the cooler 15 and is returned by a pump 16, connected to the water mains, through a pipe 17 to a tank 14 overflow from which returns to the pump through a pipe 18. Other apparatus 8 is connected to and forms a load on the supply station 7 and any power not absorbed by this load tends to drive the generators in station 7 thereby increasing the periodicity of the system and the synchronous speed of the machine 4 which thus brings the brake into partial operation.

Title: Rotor of an open end spinning device
IPC: D01H4/12
Filed: 1971-06-18
Abstract: 1363481 Open end spinning; mounting spindles MASCHINENFABRIK RIETER AG 18 June 1971 [19 June 1970] 28691/71 Heading DID  An open end spinning device comprises a by-pass path for air past the rotor shaft bearings 11, 12 whereby very little air flows through the air passages in the bearings when the device is in operation. The rotor is disposed within a housing 5, from which air is withdrawn during operation, with the rotor shaft 4 extending therefrom. The rotor shaft bearings 11, 12 are supported on the housing and comprise a body member 13 having the bearings fitted therein. The bearings 11, 12 have a first face directed towards the rotor and a second face directed towards the drive means 14 for the rotor shaft, the by-pass path for air being effective between these two faces. As shown, the air pressure at adjacent the ends of the bearings is maintained equal by making the air duct leading to the low pressure housing 5 larger than the free space through the bearings. This arrangement prevents air flowing through the bearings and thereby prevents oil &c being carried into housing 5. In alternative embodiments, the air flows in ducts around the bearing supports (Figures 2 and 3 not shown), and the air by pass path is applied to an electrostatic open-end spinning tube (Fig. 4 not shown). The rotor shaft bearings may be mounted on a vibration damper. Specification 1,363,482 is referred to.

Abstract: 1,173,947. Tape cassette apparatus. STAAR S.A. 21 June, 1967 [24 June, 1966], No. 28734/67. Heading G5R. A cassette is shifted against a first spring to an operative position, in which tape drive elements extend perpendicularly into the cassette, and may be latched in an intermediate position for fast winding, a second stronger spring biasing the latch towards the operative position. A machine generally similar to that in Specification 1,080,082 has a plate 2, carrying spindles 23, 94 and capstan 12<SP>1</SP>, coupled to the frame 1 by parallelogram links 27/30 so as to move upwards and inwards against a spring (108, Fig. 1, not shown) when tubular elements 78 on the plate are engaged by the leading edge of an inserted cassette 71. Alternatively, the plate slides parallel to the frame in arcuate guide slots (Figs. 4-6, not shown). The assembly is retained in the operative position by engagement of a lug 40 on the plate with a latch 39<SP>1</SP> on a lever 32<SP>1</SP> pivoted at 37<SP>1</SP> to a lever 132 itself pivoted at 133 and biased by the second spring 139. Depression of a button 136 moves lever 132 from stop 141 to stop 142 thereby allowing the plate and cassette to move to the intermediate position under force of the first spring (108). Depression of STOP button 150, or operation of an electromagnet 155 at the end of play, pivots latch 39<SP>1</SP> away from lug 40 allowing ejection by spring (108). In a modification, depression of either one of two control slides (182, 183, Figs. 7-8, not shown) cams a link (173) to the right or left so as to operate the lever 132 via a V-notch and roller and to carry a rod (186) controlling fast wind in opposite directions (not detailed).

E.] Oct. 8, 1934, Nos. 28775 and 28776. Addition to 440,182. [Class 94 (i)] [See also Group VI] In an arrangement for forming a continuous tobacco filler for making cigarettes, or for cutting into sections to be inserted in packages, as described in the parent Specification, in which the tobacco is fed towards a conveyer at a higher speed than that of the conveyer and is confined as to its cross-sectional size where the change in speed occurs so that the particles of tobacco are compacted axially of the filler, means are provided for feeding the tobacco towards the conveyer in the form of separated particles. In the particular forms described, the tobacco is separated into particles by being blown forwards by an air blast, or thrown forwards by a picker roller, at a higher speed than the conveyer. Figs. 1 and 2 show the air-blast form, in which the tobacco is showered down a hopper 11, 12 on the advancing paper web 10 travelling in a trough 16, the tobacco being blown forwards by jets 14 of compressed air supplied through conduits 15 at the sides of the trough. In this way, the particles of tobacco are blown forwards, before settling on the paper web, into a confining-passage formed by a plate 17 and a moving band 18, so that the compacted filler is built up and taken forward by the band 18 and the paper web, both moving at the same speed, which is less than that of the projected particles of tobacco. The tobacco may be given a forward component in the hopper by inclined plates 13, arranged as described in Specifications 325,265, [Class 1301], and 436,091. The band 18 may be replaced by a series of rollers or by a fixed plate, and both band and rollers may be roughened. Fig. 4 shows another form with a picker roller 28 throwing the tobacco particles forwards from a carded band 27 on to a conveyer 19 over which are arranged confining-rollers 20. The paper web 10 is inserted after the conveyer 19, which may move faster than the paper web, so as to give a second slowing-up in the advance of the tobacco. Air jets may be used in addition to the picker roller. Specification 387,632, [Group VI], also is referred to.
