Title: Improvements in or relating to bobbin-changing devices
IPC: A24C5/20
Filed: 1967-12-15
Abstract: 1,213,980. Feeding webs. MOLINS MACHINE CO. Ltd. and W. C. LONDON. 13 Dec., 1968 [15 Dec., 1967], No. 57040/67. Heading B8R. A bobbin-changing device comprises a carrier 5 pivotally mounted at 11 on a movable member 14 pivoted about a spindle 23, the carrier 5 having spindles 3, 4 supporting respective bobbins 1, 2 symmetrically on either side of the pivot 11 so that by rotation of the carrier the positions of the two bobbins may be interchanged, the movement of the carrier being governed by a guide so that one bobbin moves in a shorter path than the other during the interchange. As shown, the guide is constituted by a fixed cam 22 co-operating with cam followers in the form of rollers 20, 21 carried by the spindles 4, 3. The carrier 5 is connected by way of a sprocket 6, chain 7, sprocket 8 and gearing 10 to a handwheel 9, so that when the handwheel is turned anti-clockwise the carrier 5 also turns anti-clockwise about its pivot 11; since the roller 21 is constrained by the cam 22 and cannot therefore move to the right, the member 14 is caused to rotate about its pivot 23 and this motion continues until the bobbins have interchanged, positions, the straight path taken by bobbin 1 being shorter than the arcuate path taken by bobbin 2 (Figs. 2 and 3, not shown). The device may be used in a machine producing cork-tipped cigarettes, the bobbin being a full bobbin of cork strip which is moved from a loading position to an operative position when the running bobbin 2 is exhausted at the operative position.

Title: A Fog Simulator and Method for Accomplishing Airborne Simulation of a Fog.
IPC: G09B9/32
Filed: 1967-12-18
Abstract: 1,197,750. Fog simulator for aircraft. BENDIX CORP. 18 Dec., 1967 [23 Dec., 1966], No. 57316/67. Heading B7W. An airborne simulation of fog is produced by superimposing (e.g. by a partially reflecting mirror 31) on an attenuated true view (e.g. directly in the line of sight of the pilot 33 through screen 131) rays of light from a fogpattern-strip 21 which is illuminated, the rays of light passing through a collimating lens 29 so that the illuminated strip appears to be at infinity. The strip 21 is illuminated from behind, either by a lamp 23 for daytime use, the brilliance of the lamp being adjustable to match the ambient illumination, or by the outside illumination (e.g. via mirrors 125 and 128) for night-time use. The opacity of the strip 21 varies across its width from zero at a nominal horizon, and also along its length, from zero to infinity. The strip 21 may be moved along its length by a motor 1 via gearing 3 in response to a signal corresponding to the product of altitude h and a fog density a from an analogue computer 8, incorporating logarithmic potentiometers 87, 91 and receiving an altitude signal from an altimeter 73. There may be a pitch sensor 42, producing signals from which a motor 37 adjusts the tilt of the mirror 31, and for night-time use the mirror 125, so that the horizon position on the strip 21 always appears to coincide with the true horizon. The attenuation of the true view may be by a fixed screen for daytime use, or by a diffusion screen 131 and an attenuator strip 129 of varying opacity, movable by the motor 1 via shaft 136. The brightness of the lamp 23 may be adjusted manually by a potentiometer 67 to produce a zero reading on a null meter 55 which forms the bridge of a Wheatstone net, the aims of which are two photo-cells 46, 47 measuring the lamp brightness and ambient brightness respectively, and two resistors 48, 50. The position of the strip 21 (and of the strip 129, where used) is adjusted by the motor 1 whose position is controlled by a servo loop in the computer 1. In this loop the sum of the signals from the potentiometers 87 and 91, which is log a h and represents the desired strip position, is compared with a signal from a potentiometer 106 representing the actual strip position and the error is fed back via an amplifier 120 to the motor 1.

Abstract: 1,191,947. Programmed electric control of stage lighting. BROWN, BOVERI & CIE A.G. Dec. 18, 1967 [Dec. 20, 1966], No. 57386/67. Heading G3N. In a control system for stage lighting each lamp circuit 8 together with its regulating unit 7 is provided with a digital store 5 connected by individual selector keys 10 to the output of an adjustable pulse counter 4 the inputs of the pulse counter being connected to a pulse generator 1 by setting keys 2, 3 for selective subtraction or addition. The digital store values are converted in evaluators 6 into analogue values. An auxiliary converter 11 provides a visual indication of the count in the counter 4, and pilot lamps unreferenced repeat the brightness of lamps 8. The frequency of pulse generator 1 may be varied by a means which may be incorporated in a rotary switch such that the angle of rotation from a determined point determines speed of variation of brightness, and the direction of rotation determines the direction of variation i.e. increase or decrease of brightness. The system may be program controlled by means of punched cards. The pilot lamps may be in the same housing as the appropriate selector key 10.

Title: Controlling dynamic and fluid pressure brakes
Inventor: DEMAREZ R
IPC: B60L7/24
Filed: 1970-12-09
Abstract: 1323609 Fluid pressure brakes COMPAGNIE DES FREINS ET SIGNAUX WESTING- HOUSE 9 Dec 1970 [12 Dec 1969] 58438/70 Heading F2F In a train braking system having with regenerative and fluid pressure brakes a torque motor is provided with a first winding energizable in accordance with a brake control electric current corresponding to the desired braking effect and a second winding energizable with a current representative of the effective regenerative braking, the output shaft 1 of the motor being connected to a self-lapping valve 5 controlling the fluid pressure braking to transmit a force thereto proportional to the torque effective at the shaft. When the control current causes a torque to appear on shaft 1 a connecting part 2 pivots about a spindle 3 and moves a lever 9 via a fixed stop 8, corresponding movement of a further lever 12 taking place through a spring 13. The latter lever 12 causes pivoting of lever 20 via the outside ring of a bearing 17 so that a rod 4 of valve 5 is moved upwardly seating an end 27a of a hollow piston 27 on valve member 28 to isolate a chamber 25 from atmosphere, through piston 27. As the torque on shaft 1 rises vlave member 28 is unseated at 34 allowing compressed air to pass from inlet 33 to outlet 6 and the brakes via chambers 26, 25 and passage 35. When the fluid pressure on piston 27 balances the mechanical torque valve 28 is again seated until the torque is further increased. The magnetic fields produced by the first and second windings act in opposite directions so that the resultant torque force represents the deficiency of the dynamic brake in providing the desired braking effect. Changes in load of the vehicle may be compensated for by provided further levers 36, 37 moving under the action of an abutment 38 responsive to a load pressure in a chamber 48 to cause-bearing 17 to be displaced along levers 12, 20 thus changing the transmission ratio of the effort therebetween. A back-up valve 41 is provided for use when the control circuit is not functioning properly. Lowering the pressure in a train pipe 40 causes a push-rod 43 to be moved upwardly to displace a bearing 7 and act on lever 9 under an effort in the same direction as the torque produced by the control current to give in combination with the rheostatic braking effect, a total braking effect proportional to the pressure reduction in train pipe 40. The free travel left in a chamber 44 for piston 42 equals the travel of the outside ring of bearing 7 as a result of the maximum control current in the absense of rheostatic current and when chamber 25 is under maximum braking pressure. As a result, if pneumatic braking is initiated via train pipe 40 and via the control electric current, the maximum braking pressure delivered will not exceed that controlled by the control current.
