Title: An improved date-indicator for time-pieces
IPC: G04B19/253
Filed: 1938-11-18
Abstract: 522,781. Date indicators. HARRISON, T. H. Nov. 18, 1938, No. 33546. [Class 106 (iv)] A date indicator comprises two rotatably mounted members 1, 2 bearing date numerals and the names of the months respectively, a date feed lever 16 movable by means, e.g., the clockwork mechanism of a timepiece, adapted to impart an intermittent rotary feeding movement once in every twenty-four hours to the rotatable date member 1, said date lever 16 having two fixed arms 20, 21 adapted to co-operate with a pair of surplus feed cam tracks 9, 29 (one track 29 moving with the rotatable month member 2 and the other track 9 stationary), a month feed member 33 movable by means associated with the rotatable date member 1 and adapted to impart intermittent rotary movement to the rotatable month member 2, and an element 43 on the date member 1 adapted on the last day of a twenty-eight day month and of a thirty-day month to engage with one arm 20 of the date lever 16 to advance the date member 1 through an angular surplus feed movement corresponding to three days and one day respectively. The hour hand pipe 4 of a clock carries a pinion 14 which drives a gear 15 a pin 19 on which oscillates trident lever 16 once each day, an arm 25 of this lever bearing a claw 26 which engages teeth 27 to advance a member 3 bearing the names of the days of the week. The two outer arms 20, 21 carry claws 22, 23 to engage with a row of thirty-one teeth on the inner periphery of dial 1. A fixed circular wall 9 having a gap 28 separates dials 1 and 2 while the month dial 2 has a flange 29 with four gaps 30 corresponding to the thirty-day months and a longer gap 31 corresponding to February. Normally claw 22 which is wide is kept clear of the teeth 24 of dial 1 by engagement with flange 29, and claw 21 moves dial 1 one step after coming to the gap 28 in wall 9. At the end of February, long gap 31 on flange 29 is so placed that claw 22 drops down immediately behind a high tooth 43 and moves dial 1 a distance of 2¢ divisions before riding over the crest of wall 9. Claw 23 completes the movement by advancing dial 1 one-and-a-half divisions. For the thirty-day months, shorter gaps 30 are so disposed that claw 22 moves dial 1 half a division and claw 23 the remaining one-and-a-half divisions. For the other months no gaps are provided in flange 29 and claw 22 does not engage tooth 43. At the end of each month, pin 32 on dial 1 contacts the toe portion of month lever 33 which has a claw 34 which by engaging one of twelve teeth 35 moves forward month dial 2 one step. Small rubber rollers 39, Fig. 9, are used for adjustment of the dials in leap years, springs 42 preventing backward rotation and holding the rollers 39 against their apertures to keep dust out of the case.

Title: Improvements in or relating to the production of metal sheets or plates
IPC: C22F1/05
Filed: 1964-08-19
Abstract: 1,015,280. Making sheet metal; working at specified temperatures. KAISER ALUMINUM & CHEMICAL CORPORATION. Aug. 19, 1964 [Sept. 6, 1963], No. 33910/64. Headings B3A and B3V. A method of producing aluminium sheet comprises solution heating an aluminium body, rolling the body at solution heating temperature, maintaining the rolled body at this temperature and passing the sheet through further rolls wherein the thickness is reduced to the required value and the temperature is reduced to below 450 F. The term " aluminium " includes alloys thereof and clad aluminium and the term " sheet " includes plate and foil. In one example described in the Specification a magnesium silicide aluminium alloy ingot was heated for three hours at approximately 930 F., rolled into a slab and maintained at a temperature of approximately 940 F. During further rolling to plate thickness the temperature was reduced from 940 to 920 F. and at this temperature the plate was introduced to a quench rolling mill. In this mill the plate was reduced to sheet while the temperature was lowered to 360 F. Following quench rolling the sheet was cold rolled and finally artificially aged, which process left the finish of the cold rolled sheet unaffected.

Title: Kinematograph projection apparatus with a continuously moved film
IPC: G03B41/10
Filed: 1931-12-07
Abstract: 376,172. Kinematograph apparatus. I. G. FARBENINDUSTRIE AKT.-GES., Frankfort-on-Main, Germany. Dec. 7, 1931, No. 33920. Convention date, March 16. [Class 97 (i).] The return movements of a rocking compensating mirror in a continuous-feed apparatus are controlled by the passage of a light beam through the film on to a photo-electric or selenium cell. As shown, the perforated margin of a film is blackened, and light from a source 7 and condenser 8 passes through the perforations as they pass an opening over a photoelectric cell 9. An electromagnet 11 is thereby caused to attract a spring-pulled contact plate 12 in the circuit of an electromagnet 14. The mirror 4 is frictionally connected to a constantly driven gear wheel producing its forward movements, and the magnet 14, when energized. attracts a lever 15 secured to the mirror to produce a return movement of the mirror, such movements being permitted by the frictional connection to the gear wheeL If the film has more than one perforation per picture, a shutter moved synchronously with the film covers all except one of the perforations for each picture. In unperforated films, light spaces in a blackened margin control the light beam.

Title: Device for measuring the diameter of thin fibres
Inventor: FONTANEL ANDRE
IPC: B65H63/06
Filed: 1969-07-04
Abstract: 1280211 Photo-electric measurement of thickness INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 4 July 1969 [4 July 1968] 33929/69 Heading G1A [Also in Division G2] Fibre diameters are measured by locating a fibre O on a support M in a beam of coherent light, the support M being rotatable about the longitudinal axis of the fibre and movable parallel to or perpendicular to the optical axis X-X<SP>1</SP>, the illuminating beam being made convergent by a lens L 3  either before or after the fibre O, and recording the diffraction pattern of the fibre. Preferably the lens L 3  is located before fibre O so that the fibre is illuminated with a convergent beam. An adjustable diaphragm D 2 , comprising two pairs of adjustable blades at right angles to each other and at 45 degrees to a third pair, is located in a collimated beam from source 5 but before lens L 3 . The fibre is fixed at its ends in two parallel rotatable discs 4 mounted on a frame 12, Fig. 5, movable on a base 13. Rotational movement is obtained by turning a rod 8 which drives disc 4. Movement parallel to the optic axis is achieved by means 14 and perpendicular to it (i.e. vertical movement) by means 15. In an alternative mount, Fig.15 (not shown), the frame is mounted on the base through a cup to enable the inclination of the fibre to be adjusted. The diffraction pattern is recorded on means P which may be a photographic plate, viewing screen or photo-electric detector. The recorder P is located in the back focal plane of lens L 3 . Undesired diffraction patterns are removed by a spatial filter F. In an alternative embodiment, Fig. 9, for measuring the elliptical nature of a fibre the convergent beam from the lens L 3  is split at 25 and the two beams, via mirrors 26, 27 illuminate fibre O. Only part 30, 31 of each beam is diffracted. Mirrors 32, 33 reflect, for each beam, a portion 36, 37 of diffracted light and a portion 34, 35 of undiffracted light to recording means. But the mirrors 32, 33 are so located that only half of each diffraction pattern, starting from the centre, is reflected to detector P. The two reflected halves are caused to be adjacent in the recording plane, with their respective centres in exact coincidence. To assist in measuring the fibre diameter a photograph may be taken of the diffraction pattern. The fibre is then replaced by a screen having a linear array of holes of known diameter, which is less than the mean diameter of the fibre being measured. The diffraction pattern from this is superimposed on the photograph. Alternatively the screen may comprise transparent concentric circles the radius of each of which differs by a constant amount, equal to the radius of the smallest circle, from that of the next largest circle.

Title: Rack and pinion power assisted steering
IPC: B62D5/087
Filed: 1972-07-20
Abstract: 1380360 Power steering CAM GEARS Ltd 10 July 1973 [20 July 1972] 34039/72 Heading B7H In an hydraulic power assisted steering system including a valve spool 17 actuated axially in response to relative rotational and axial movement of two members 13, 22 interconnected by helically disposed resilient elements 24, the valve spool 17 is adapted to be urged against the actuation by a servomotor pressure resulting from the actuation. In a preferred embodiment steering torque from splined connection 21 is transmitted via helical spring wires or beams 24 to lower element 22 coupled by a pin 23 to column part 3. Relative rotation between connection 21 and part 3 causes rod 15, locked with element 13 and connected by pin 16, to move valve spool 17 axially. The ends of the spool 17, i.e. 17A and 17B, are sealed by 0-rings in body 18 thus forming pressure chambers 18A, 18B connected by ducts 20 to connections 19C, 19D which supply one or other ends of the servomotor cylinder 8 formed on a rack bar 6. The part 3 has a pinion which engages a rack on bar 6. When one of the connections, e.g. 19D, is pressurized from an accumulator via connection 19A, like pressure is applied in chamber 18B to the end of the spool which is urged in this case upwards tending to return the spool to its centre position. The rod 15 having a slot 15A is screwed in element 13 and locked by a grubscrew 15B which arrangement affords adjustment of spool 17 in its body 18. Parallel pins 14 act as cotter pins to provide torque between parts 13, 3 in the event of hydraulic failure. In an alternative arrangement an open centre valve arrangement, in which the supply of pressure fluid is of continuous nature such as an engine driven pump, is employed.

Filed: 1932-12-05
Abstract: 410,230. Electric transformers. GAKLE, W. F., 2153, 5th Avenue, Bay City, Michigan, U.S.A. Dec. 5, 1932, No. 34435. [Class 38 (ii).] In the construction of a loop-shaped magnetic core member for a transformer by arranging a plurality of strips of sheet metal of different widths in superimposed relation and thereafter bending them to locate intermediate portions of the strips in position to form an inner core leg and the end portions to form an outer core leg which can be opened, the strips are annealed after they have been so bent. The arrangement of the strips is preferably such that their width, and therefore the cross-section of the legs, decreases from the inner to the outer perimeter of the core. The strips are suitably obtained by cutting a trapezoidal sheet metal plate 1, Fig. 3, into parallel strips of widths successively increasing from the longer parallel edge 2 to the shorter parallel edge 3. In assembling the core member, the strips may be piled on one another with the shortest and widest strip at the bottom, fastened together by wires or the like, and bent to loop form, the longest and narrowest strip being at the outer perimeter of the loop and the ends 10 of the individual strips overlapping as shown in Fig. 1. In this condition the strips are secured by clamps or wire and annealed. The complete core is made by assembling a number, e.g. four, of such core members as shown in Fig. 2. To facilitate the winding of the coil 12, Fig. 1, on the assembled core, the ends 10 are opened and held against spaced disc members 13, Fig. 8, by clamps comprising spaced adjustable bolts 15 with hook-shaped ends engaging cross members 16, a crank (not shown) being provided for turning the whole device in winding. After winding, the ends 10 are returned to closed position. The reduction of the cross-section of the core toward the centre results in better and more uniform radiation of heat.

Patent GB-486842-A (GB)
Title: Improvements in or relating to machines for the manufacture of glass articles
IPC: C03B9/24
Filed: 1937-12-14
Abstract: 486,842. Glass manufacture. BRITISH BOTTLES, Ltd., and HUNT, S. Dec. 14, 1937, No. 34561. [Class 56] Relates to a glassware-forming machine of the kind in which mould units move through an endless path and in which means are provided for partly opening each parison mould for a desired period before the full opening. According to the present invention, means are provided in connection with each mould unit for adjusting the position in the cycle of movement at which the preliminary opening occurs, the arrangement preferably being such that the time of opening can be adjusted independently for each parison mould. Fig. 1 shows the invention applied to a suction-gathering machine of the rotary type in which the mould units are supported by parallel columns 22 on the mould table 20. The parison moulds 23 are opened and closed by a fixed cam. 28 which moves a slide 31 having a yoke 32 that embraces a rod 33 connected to the mould arms. The inner portion 30 of the slide 31 slides within the outer portion, and is connected to it by springs 37 which are compressed when the mould is closed. If the slide 30 is then moved towards the centre of the machine, the springs 37 will be compressed further and the mould will be opened slightly. For this purpose, arms 39 pivoted on the inner sides of the columns 22 have their lower ends connected by a slotted crossbar 41, and a cam roll 43 can be secured in any position in the slot. The cross-bar co-operates with a rocking bar 40, pivoted to the columns 22, which has on its upper side a projecting lug that bears against the lower end of the yoke 32. The cam roll 43 can be positioned upwards or downwards in order to engage either of two cams 49, 50 which are suitably attached to portions of the main cams. When the roll engages either of the cams 49, 50, the bar 46 is rocked and presses the yoke 33 slightly inwards, thus partly opening the mould. The time of opening of any of the parison moulds can be altered, without altering the main cam 28, by adjusting the position of the cam roll 43 in the slot in the bar 41, and arranging the roll to make contact with either of the cams 49, 50.
