IPC: B62B9/14
Filed: 1922-12-22
Abstract: 204,610. Smith, H. H., and Brettell, G. P. Dec. 22, 1922. Pivoting adjustments.-The tubular arms 1 of a folding stay, such as for the collapsable hood of a perambulator, are held in an adjusted position by a pawl 8 on one member of the joint engaging ratchet-teeth 9 or stops on the other member of the joint, the joint consisting of plate members 6 each provided with an extension 6<a> engaging the tubular arms 1, and disc members 5 mounted on a pivot pin 4 between the outer knuckle-joint plates 2 of the tubular arms. The plate members 6 are cranked or off-set from the disc members 5 so as to be in the same plane for the engagement of the pawl 8 on one member with the teeth 9 on the other member. The portion of the plate member having ratchet-teeth projects through a slot 9 of the tubular arm 1, as shown. Instead of forming the plates 6 as offset members from the discs 5, as shown in Fig. 4, a single disc 5 on one of the members 6 may be disposed on the pivot 4 between a pair of plates on the other member 6.

Abstract: <PICT:0834610/III/1> <PICT:0834610/III/2> <PICT:0834610/III/3> <PICT:0834610/III/4> An evaporating and drying or cooling apparatus comprises a housing in which is horizontally mounted a flexible endless conveyer having attached thereto material moving elements adapted to move material along an adjacent table which is heated or cooled by an adjacent heat exchanger, movably mounted conveyer guide members and resilient elements urging said guide members, the conveyer and the material-moving elements into yielding engagement with the table.  Material is introduced by conduit 24 (Fig. 1) if wet-solid or 25 if liquid and is led by the curved section 62 on to the beginning of the table 55 which is heated by elements 91 which may be of any suitable type such as electrical, oil or gas-fired, steam, hot water or infra-red operated.  The material is moved along the table by the elements 60 which stretch across the width of the housing.  They comprise scrapers 44 (Fig. 4) of resilient material such as spring steel having vapour outlets 68 and which are mounted on channels 41 which are carried each side by endless chains 39 running over sprockets and driven from one end.  An alternative form comprises a rigid or resilient strip 241 of sheet metal attached to the channel (Fig. 11). Corner scrapers 50 (Fig. 6) are also fitted. The ends of the channels 41 run under guide means which are angle-plates 59 having upturned ends 61, being pivoted at one end at 67 and spring-loaded along their lengths by springs 66 urging the scrapers against the table.  The material reaching the end of the table falls into the trough 96, from where it is continuously removed by a flight conveyer 102 having an endless belt with circular flights 113 attached thereto moving through a tube and discharging at its upper end into a conduit 109.  Pressure sealing members 110 may be used when the apparatus is used under increased or reduced pressure. In a modification having a completely sealed housing the initial material is introduced by a similar flight conveyer. In a further modification (Fig. 7, not shown) the apparatus is tiltable to raise the discharge end so that liquid accumulates at the inlet end and can be retained there in greater quantities. The apparatus can be used for drying food or chemical products.

Title: Ranging system
Inventor: SKAGERLUND LARS-ERIK
IPC: G01S17/14
Filed: 1969-07-11
Abstract: 1,271,245. Laser rangefinders. BOFORS A.B. 11 July, 1969 [12 July, 1968; 26 July, 1968], No. 35145/69. Heading H4D. Specification describes a pulsed laser rangefinder of the type wherein the transmission of a pulse 1 opens a gate 6, Fig. 1, coupling the output of a pulse oscillator 5 to a first pulse counter 7 and is arranged such that said one first counter can provide counts indicating the ranges of a plurality of targets including the selected target. Thus a plurality of registers 31, 32, 33 are connected to the counter 7, via gates 21, 22, 23 and opened in succession by the first, second and third echoes by means of distributer 40 fed by receiver terminal 2, whereby the count content of said counter is transferred to each register in turn, at the moment of echo receptions, said transferred counts thus indicating the respective plurality of ranges. So that near targets or clutter will not be received a gate 3 is placed in the line from receiver terminal 2 to distributer 40 and is opened only after an interval after the transmission of a pulse as determined by delay 4. Counter 7 is comprised of bi-stable circuits to give a binary coded decimal output. At the instant of reception of an echo, the bi-stable circuits of counter 7 may be in a state of switch over, which state if read out to a register would indicate an erroneous range. A second counter 14 may be thus provided commencing to count the oscillator 5 output on the reception of an echo pulse and also causing the simultaneous blockage of gate 6 and the stop of the count in counter 7. After a period long enough for the bi-stable circuits of counter 7 to settle, and determined by the count reached in counter 14, said counter 14 reopens gate 6 and recommences the count in counter 7 starting with a jump equal to said count reached. Counter 14 also then feeds a signal to distributer 40 such that the echo is then applied to the respective one of gates 21, 22, 23 whereby the "settled" state of counter 7 is passed to the register. In the arrangement of Fig. 2 only those two ranges of incoming echoes which bracket the suspected range of a target are stored in registers 31 and 32. Items 1 to 7, 21, 22, 31, 32 are as in Fig. 1. The suspected range Rs is fed into comparator 56 and is compared with the continually changing count in counter 7 to give an output at 58 indicating when the count range R is less than Rs and when it is greater than Rs. Said output is fed to control switch 52 such that the echoes for R<Rs are fed to gate 21 and the first only echo for R>Rs is fed to gate 22. Register 31 is cleared before the next opening of gate 21 such that the range which remains in it is that nearest to and just below Ri. The range in register 32 is that nearest to and just above Rs.

Title: Improvements in and relating to electric variable-speed powertransmission systems
IPC: F16H61/00
Filed: 1929-11-21
Abstract: 341,201. Electromechanical power transmission. JEFFCOTT, H. H., Storth Holme, Ashley Park Road, Walton-on- Thames. Nov. 21, 1929, No. 35660. [Classes 35 and 38 (iv).] A variable-speed power-transmission system comprises primary and secondary rotary elements on different axes and associated with one or more magnetic fields and means for altering the speed ratio between the elements by varying the effective action of the field or fields. The field or fields may be provided in small-power systems by help of permanent magnets. A driving shaft 3 may carry a primary member 2 in two parts embracing three secondary members 4 on separate axes 5 geared to a driven shaft 22 with provision for interchanging gears 21, 23 for reversal. The primary may have two sets of windings 8, 9 at different effective radii each producing a ring of alternate poles. The secondary members may carry windings or a shortcircuited winding 16 coacting with the magnetic fields. By varying the relative strength of the exciting current applied through slip rings 12 to the coils 8, 9 respectively the torque and speed ratio between primary and secondary elements may be varied. This may be done automatically according to desired conditions for example by mechanism centrifugally operated from the driving and driven shafts 24, 25 and sliding and rotating respectively a suitably formed compound cam 28 on a spindle. Rheostats 35 in the circuits of the field windings may be operated by a bell-crank lever one end of which rides upon the cam. Heavy pattern speedometer mechanisms may be used to actuate the cam. The rheostats may be directly operated from the centrifugal mechanism. According to modifications of the induction fully energized fields may be maintained and the magnetic flux moved radially by iron pieces between primary and secondary elements. The amount of overlap between the elements may be changed by moving the axes of the secondaries about a third centre. The energizing currents may be generated in the mechanism as by a winding or windings on the secondary elements connected to a commutator or slip rings. Alternating current or direct current may be used for excitation and a rotating magnetic field may be produced by the use of the former. The secondary windings may be omitted and eddy currents relied on.

Abstract: 807,555. Supports for photographic cameras. VINTEN Ltd., W., and VINTEN, W. P. Nov. 28, 1956 [Dec. 14, 1955], No. 35882/55. Class 97(1) In a tilting mounting especially for a camera, a supporting plate is pivoted on a vertically movable guide and, the guide is constrained by a cam to move by an amount such that the centre of gravity of a camera mounted on the plate can move, on tilting the plate, only in a horizontal plane. As shown in Fig. 1, camera supporting plate 21 is carried on a pair of bars 18 guided for vertical movement by ball bearings 16 mounted between a frame 10 and external plates 15. Frame 10 is rotatable about a vertical axis. On tilting plate 21, the co-operation of the edges of a pair of cam plates 22 with fixed rollers 23 constrains bar 18 to move vertically upwards so that the centre of gravity of a camera for which the apparatus is, designed remains in a fixed horizontal plane. In another form, Fig. 3, the cam plates 30 are fixed and co-operate with rollers 37 carried on bell crank levers 31 pivoted at 32 to bars 18. Pivoted links 34 rotate levers 31 about pivots 32 as plate 21 is tilted. Bars 18 are thus constrained to move vertically upwards as before Levers 31 may be pivoted in either of holes 38 in bar 18 and connected to link 34 by either of holes 39 to adjust the apparatus for cameras having centres of gravity at different heights above plate 21. According to the Provisional Specification, the rollers which co-operate with the cam plates may alternatively be fixed to the supporting plate. Adjustable resistance to movement or locking of plate 21 in a given position may be effected by making pivot 33 screw threaded and providing a wing nut and friction washers. Similarly, in Fig. 1, the rotation of rollers 23 driven by the cam plate may be controlled by braking means and a separate locking plate provided.
