Title: Spindle for supporting a reel
Inventor: BUNTING LESLIE JOHN
IPC: G03B17/30
Filed: 1967-11-01
Abstract: 1,209,475. Securing reels on shafts. EASTMAN KODAK CO. 1 Nov., 1967 [1 Nov., 1966], No. 49651/67. Heading F2U. [Also in Division G2] A spindle 10 for rotatably supporting a film reel 28 on a fixed shaft 18 of a projector comprises a hollow cylindrical plastics body having an integral wall 15 dividing the bore therethrough into chambers 12, 14 each open at its end remote from the wall 15, the chamber 12 being adapted to receive the fixed shaft 18 and the chamber 14 housing a spring key 20 a limb 40 of which extends from the spindle surface to drivingly engage a slot 30 of the reel 28. A spring 22 lying in a plane at right angles to the key 20 is also housed in the chamber 14 with its two limbs (54), (Fig. 4, not shown), in axial slots (58) and end portions (56) of the limbs extending from the spindle surface to retain the reel on the spindle. An end cap 24 retains the key 20 and spring 22 in position and forms a bottom surface to parts of slot 48 (58). A spring clip 66 engages a groove 72 round the fixed shaft 18 to axially locate the spindle. A damping fluid is put into the chamber 12 before the spindle is pushed on to the shaft 18 to damp torsional oscillations of the spindle. A lug (36) (Fig. 1, not shown) is drivingly engageable by a lug 34 on a pulley 32 freely rotatable on the shaft 18.

Title: Control systems for preventing swinging of suspended loads
Inventor: NEWMAN WILLIAM MAXWELL
IPC: B66C13/06
Filed: 1964-12-08
Abstract: 1,132,967. Preventing grabs from swinging. DAVY & UNITED INSTRUMENTS Ltd. 7 Dec., 1965 [8 Dec., 1964], No. 49910/64. Heading B8B. The travelling crab 4 of an ore unloader is accelerated and decelerated during traversing movements by a control device in such a manner that at the end of the periods of acceleration or deceleration the grab 3 is moving at zero angular velocity, thereby avoiding swinging relative to the crab. The movements of the grab during unloading are automatically controlled by the control system described in Specification 1,083,132. In practice acceleration and deceleration are effected in two bursts separated by a period of running at a constant velocity, or accelerating or decelerating at a different rate. The pre-selected programme is calculated and final adjustments are made by observations on the movements of the grab in use. In Fig. 4, (not shown), a motor 30 of the cross traverse winch has coupled to it a position transducer which applies to a comparator circuit 33 a position signal. This is compared with a reference signal, applied along a line 29, which represents the terminal position of the grab. An error signal representing the difference between the actual and required positions is applied by circuit 33 through contacts 34 to a swing control unit 35. The latter controls the cross traverse speed according to the preselected pattern. The output from unit 35 is applied to a control unit 36 for the winch motor 30. A similar system controls the height of the grab. A circuit for the control of acceleration and deceleration is illustrated in Figs. 5A, 5B (not shown).

Title: Electronic watch
IPC: G04C3/00
Filed: 1970-10-30
Abstract: 1313010 Electronic watches HAMILTON WATCH CO 30 Oct 1970 [13 Aug 1970] 51799/70 Heading G3T A battery powered electronic wrist watch comprises a crystal controlled oscillator circuit the high frequency output (262, 144 Hz) of which is fed to a frequency divider which produces therefrom low frequency (16 Hz) timing impulses to drive an electro-mechanical resonator which is coupled via a gear train to hour, minute and second hands and to a date indicating ring. The natural frequency of the resonator is adjustable to correspond to the output frequency of the divider. Setting means is also described. The oscillator circuit 12 (Fig.4) comprises a quartz crystal 76 connected between gates and drains of complementary M.O.S. field-effect transistors 78, 80. Fine tuning is by capacitor 84. Complementary output signals on lines 86, 88 from the oscillator are applied to a first stage 90 of a 14-stage integrated circuit frequency divider 16 comprising a chain of flip-flops. The output of stage FF-14 is fed to a driver 20 including an RC differentiator 94, 92. The differentiated pulses are applied to gates of a complementary pair of field effect transistors 96, 98 the output of which is fed via resistor 100 to a switching transistor 104. Thus transistor 104 will supply drive current pulses, derived from the battery at 68, 70, to a coil 30 of the electro-mechanical resonator causing the coil to oscillate in a permanent magnet field at 16 Hz. In a modification Fig.4A (not shown) the complementary pairs of transistors are also included in the integrated circuit. The electro-mechanical resonator comprises an armature coil 30 (Fig. 2) on a core (not shown) journalled by 'balance' staff sections 34, 36 in bearings 38, 40 for oscillatory movement in the field of magnets 26, 28. The staff drives an eccentric 54 on which is pivotted one end of a lever 56 which transmits oscillatory movement of the staff to an index wheel 58. A hairspring 42, the effective length of which is adjustable in a conventional manner to adjust the natural frequency of the resonator, has six times the stiffness of lower hairspring 48. The springs carry current from the drive circuit to the coil. A setting stem (148) Fig.7 (not shown) has two positions. In its innermost position the watch will run normally and rotation of the stem causes a rapid set assembly to rotate a calendar ring (218) having radially inwardly facing teeth (222). At its outermost position the stem acts to positively brake the gear train and open a switch Fig. 9C (not shown) in the battery circuit, and rotation of the stem acts through a setting wheel to set the hands and the date indicator. Electrical inter-connections are formed on a printed circuit board. The back of the watch is electrically conductive and bears resiliently against a 3 volt circular battery to form a negative pole terminal thereof.

Abstract: 1371465 Optical sample holders UNITED STATES ATOMIC ENERGY COMMISSION 16 Nov 1972 [9 Dec 1971] 52878/72 Heading G2J [Also in Division B2] In a photo-metric analyzer for use under conditions of weightlessness a rotor 1 having a ring of sample analysis cuvettes 7 is removably supported on a motor driven housing 2 and held there by a key and a magnet. A light source 6 sends a beam through the cuvettes 7 to a photo-multiplier tube 9 via an adjustable filter selector 11. The housing 2 is braked by a solenoid disk brake assembly 14 and controlled by a pick-up head rotor position indicator comprising photo-diodes. The rotor 1 comprises an opaque plastics disk sandwiched between two transparent plastics disks. A sample is injected through a centrally located part 21 to a sample distribution chamber 20 from where it flows under centrifugal pressure down capillary passageways 22 to overflow collection cavities 24 and to the first arm, but not the second, of passageways 25 which terminate in the cuvettes 7.

Abstract: 1415680 Mechanical interrupters BUNKER RAMO CORP 17 Nov 1972 [8 Dec 1971] 53259/72 Heading H1N [Also in Division G3] In a clockwork mechanism driven by a helical mainspring 8 one end of which is fixed to a driving shaft 17, e.g. by means of a disc 22 locked on the shaft, and the other end of which is fixed to a winding wheel 9 whereby the spring is wound when a rotary electric motor 13 is energized, the motor is supplied via a switch 24 comprising a pair of resilient contact blades 27, 28 which are biased together and a switch operating member 41 which is mounted for rotation about the shaft 17 and includes a plurality of insulating arms 40, the member 41 being driven alternately by the wheel 9, during winding, so that one arm 40 is eventually brought between the contacts to stop the motor, and by the mainspring, while the motor is idle, eventually to remove the arm from between the contacts and energize the motor. As shown the wheel 9 has an extended hub 43 mounted on a fixed pipe 14 which also supports the shaft 17. A wheel 18 on the shaft 17 drives clock movement 7 and a lug 48 on the disc 22 drives the switching member 41. A lug 45 fixed to the hub 43 likewise drives the member 41. The lugs 45, 48 lie in a peripheral notch (47, Fig. 1, not shown) of the member 41 and alternately overrun each other, the one bringing an arm 40 between the contact blades and then the other driving the arm 40 right through. Each arm 40 is wedge shaped and has slightly abrasive sides to clean the contacts. If supply battery 13a fails or is removed, complete unwinding of the spring 8 is prevented by a fixed resilient finger (50) which blocks a switching arm 40 to stop the shaft 17 but which is light enough to be deflected by the motor drive.
