Title: Improvements in or relating to perambulators and like vehicles
IPC: B62B9/04
Filed: 1945-08-17
Abstract: 597,369. Rest bars for perambulators and like vehicles; perambulators &c. convertible into sledges. UPTON, W. J., TOZER, S., and BROOK, W. H. Aug. 17, 1945, No. 21009. [Classes 108 (i) and 108 (ii)] Movement of a perambulator or like vehicle up and down stairs is facilitated by the provision of runners 28 normally held in the raised inoperative position (shown in broken lines) and adapted to be lowered to afford slidable supports in such a manner that the vehicle body 3 is maintained substantially horizontal while negotiating the stairs. The runners 28 which are preferably of wood are connected to the front and rear axles by two pairs of pivotally mounted links 13, 22 respectively. A transverse member 35 bridging the front links 13 carries a nut 38 which engages the thread of a spindle 39 having an operating handle 52 and supported by a bearing 40 mounted centrally on the rear axle by trunnions. In an alternative construction, Fig. 8 (not shown), the front links 13 have short upward extensions connected by a transverse member coupled to the end of a push rod which is supported in a bearing adjacent its other end and is provided with an operating knob: A projection on the rod cooperates with the end surfaces of the bearing to limit its two positions corresponding to the operative and inoperative positions of the support The push rod may be operated by a flexible cable control. In both constructions the runners are arranged when in their operative position to lie substantially tangential to the periphery of the rear wheels and they are long enough to contact two successive stair treads.

Title: Improvements in or relating to driving arrangements for rotary printing machines
IPC: B41F13/00
Filed: 1923-08-22
Abstract: 204,311. Maschinenfabrik Augsburg- N³rnberg Akt.-Ges. Sept. 20, 1922, [Convention date]. Gearing for starting and stopping machinery. -Rotary printing-machine are driven at the start by an auxiliary slow speed drive which is cutout when the main drive attains a speed greater than the low speed, the arrangement being such that the auxiliary drive takes place through a gear wheel which is mounted so as to be released automatically from the wheel it drives. As shown, the printing-machine is geared to the shaft 11<a> of the main motor, and the auxiliary motor 1 is geared by a wheel 17 to a countershaft 5 geared by a wheel 13 to a wheel 10 mounted in a quadrant lever 9 pivoted about the shaft 5. The lever 9 is moved to bring the wheel 10 into gear with the wheel 11 when the axuiliary motor is started ,by a pawl 7 on a three-armed lever 4 which is actuated to release the machine brakes 2 by an electromagnetically-operated rod 6 acting through a spring 14. When the main motor is thrown in, the lever 9 is returned to its inoperative position on the wheel 11 attaining a greater speed than wheel 10 by the action of the teeth of the whee 11, which act to move the lever 9 in a clockwise direction, and so moves the wheel 10 out of gear. A stop 12 limits the motion of lever 9, and a spring 8 causes the pawl 7 to re-engage notch 9<1> when the brake is put on. The machine may also be driven by hand in either direction by moving wheel 17 axially into gear. The lever which changes the gear energizes the brake-magnet to release the brake and throw in wheel 10. A bolt 21 is also operated to lock the lever 9 in position, and allow the machine to be driven in either direction by the hand-drive.

Filed: 1974-05-14
Abstract: 1466369 Shutter-diaphragm POLAROID CORP 14 May 1974 [22 May 1973] 21291/74 Heading G2A A shutter-diaphragm is opened and closed in discrete steps by a stepper motor 60. As shown, a shutter-diaphragm comprises blades 26, 28 having apertures 30, 32 which overlap to form an exposure aperture, and apertures 46, 48, which overlap to form an aperture for a photo-cell of a light sensing circuit, (136), Fig. 7 (not shown). As described, pulses are fed to motor 60 which drives a pinion 34 engaging racks on the blades to open the exposure aperture until an exposure terminating signal is received from the light-sensing circuit. The motor is stopped and, after a one pulse delay to allow for inertia, is reversed to close the shutter. If full aperture is reached before receipt of the exposure terminating signal, a pulse counter (154) stops the motor and the aperture is held open until the terminating signal is received. Preferably the shutter is closed by pulses of higher frequency than the opening pulses. Logic controlling the whole sequence of operations in an SLR camera is described.

In a method of air treatment of wire emerging directly from a rolling mill as described and claimed in Specification 1,121,870, cooling air is introduced tangentially in individual flow paths at several positions on the shaft circumference and at an upward angle. The cooling air passages are formed in a duct 16 by a number of channel walls 31b, which are shaped to form a horizontal constriction 31a and to direct air tangentially on to the coils of wire. The cooling air is also upwardly directed by intermediate plates 32 at an angle α which increases with respect to the horizontal towards the top of the duct 16, but the width of the passages remains constant in the vertical plane.

Abstract: 1303932 Feeding screw extruders BOHLER & CO AG Gebr 19 April 1971 [10 Feb 1970] 21481/71 Heading B5A [Also in Division B8] Apparatus for supplying flowable material e.g. coating composition for welding electrodes to a screw extruder (not shown) comprises a feed hopper 20 whose opening 27 is adjacent to the extruder, a conveyer (10), Fig. 2 (not shown), which supplies the material to the hopper 20, two driven feed screws 21, 22 located within the hopper 20 and mounted on a beam 30 which is pivotally movable about a pin 32. When the feed hopper 20 contains a small amount of material the axial thrust exerted by the feed screws 21, 22 is small so that a switch 41 is closed which causes current to flow from a motor 11 to drive the conveyer (10). When the hopper 20 contains a large amount of material the axial thrust of the feed screws 21, 22 raises the beam 30 thus opening switch 41 thereby stopping the conveyer (10) and the supply of material to the hopper 20.

[Also in Groups XXX and XXXVI] A current collector for use with a slip ring or commutator comprises a roller 1, Fig. 2, shown engaging a slip ring 2 and having a shaft 26 supported in bearings 5, 6 between side plates 7, 8 said shaft having an extension 25 received in a stationary cup 27 containing mercury and having a connecting cable 28 attached thereto, the shaft and the cup carrying concentric sleeves 30, 31 respectively of steel or other material which is not wetted by the mercury and between which there is a small running clearance to prevent egress of mercury from the cup. The framework of which the side plates 7, 8 form part is spring biased towards the slip ring 2. Fig. 3 shows an alternative construction wherein the roller 1<SP>1</SP> is hollow and a stationary spindle 39 having the conductor 28 attached thereto passes through a bush 35 closing one face of the hollow roller and has a head 40 located in said hollow which contains the mercury. A steel sealing sleeve 41 is fitted to the rod. To reduce the speed of the contact roller where it engages a large slip ring, an intermediate dumb-bell shaped roller 47, Fig. 5, may be interposed between the slip ring 2 and the contact roller 46, the large diameter portion 48 of the roller 47 engaging the slip ring and the small diameter portion 49 engaging the roller 46. Fig. 7 shows an arrangement wherein two contact rollers 51, 52 constructed according to Figs. 2 or 3 and displaced round the periphery of the slip ring are connected in parallel to reduce sparking in the event of temporary impairment of contact at one of the rollers. A sliding brush may replace one of the rollers (Fig. 8, not shown). Selfcleaning of the contacting surface of the roller and slip ring may be provided for by setting the axis of the roller at a slight angle to the axis of the slip ring so that a small amount of slip occurs, and concentration of the contact pressure may be obtained by crowning the surface of the slip ring and/or the roller. Where the contact roller is used with a commutator, the bars 67, Fig. 11, of the latter may be set at an angle or each bar divided into two circumferentially offset parts 69, 70 as shown in Fig. 12, so as to ensure that the roller engages an oncoming bar before breaking contact with a receding one. Suitable materials for the contact surfaces of the roller and slip ring are referred to, e.g. copper, steel, silver, stainless steel, rhodiumplating. Specification 777.335, [Group XXXVI], is referred to.
