Patent GB-1547689-A (GB)
Title: Locomotive brake system
IPC: B60T13/66
Filed: 1977-11-02
Abstract: The brake arrangement has a first brake circuit (8, 1, 3, 4, 5, 6), which feeds compressed air for the direct braking of the locomotive and is vented in order to release the brakes of the locomotive. In addition, a second brake circuit (8, 2, 9, 14, 15) is provided, which vents the brake circuit of the train in order to produce indirect braking of the train, if one is coupled up, and which delivers compressed air for releasing the brakes of the train. The arrangement has a main compressed air reservoir (8), an auxiliary compressed air reservoir (15) and a double main brake valve (1, 2), which has two jointly operated parts. One (1) of these parts is arranged in such a way that on braking, it connects the main reservoir tank (8) to the brakes (6, 7) of the locomotive in order to brake the locomotive directly. The other part (2) is arranged in such a way that it causes the brake circuit (12) of the train to be vented in order to brake the coupled train indirectly. A second valve (14) is arranged in order to keep the brake circuit of the train connected to the auxiliary reservoir tank when the brakes are released. This increases the operating reliability compared to known brake devices. <IMAGE>

As shown, books carried through a casing in machine on saddles 3 carried by a chain conveyer are finally moved vertically downwards on the saddles. A cylinder 17 with openings 18, 37 spaced 60 degrees apart and a diametrically opposite opening 19 extending over 60 degrees is situated in the path of the saddles 3, so that a saddle can pass through one of the openings 18, 37 (the opening 18, Fig. 2) and the opening 19 to deposite a book on the cylinder. A rake device 32 and a plate 30 form with the cylinder 17 a pocket to receive the book.

Abstract: 1,109,109. Tool-clamping. CHARLES CHURCHILL & CO. Ltd. 27 Oct., 1966 [3 Nov., 1965], No. 46566/65. Heading B3B. A machine tool spindle 2 comprises a tapered socket 20 and spring-loaded jaws 5 for engaging an arbor end (6A) and means for positively clamping the jaws. The spindle has splines 23 to engage a driving gear (25) and is fed by a screw 4 rotated by gearing 24.

Abstract: 1329515 Blasting INTERNATIONAL BUSINESS MACHINES CORP 14 Oct 1971 [25 Nov 1970] 47817/71 Heading B3D [Also in Division H1] A machine for abrading a resistor 1 which may be bonded on a ceramic substrate, with the use of grit in an air-stream through a nozzle 3 comprises a Kelvin Bridge network 30 for monitoring the resistance value to control the rate of removal of the resistive material in response to the monitored value such that as the predetermined value of the resistor is approached the nozzle is slowed down and finally stopped at which time the eroding particle stream is switched off. The apparatus may abrade eight resistors at eight abrading stations under control of an eight-way logic circuit. The apparatus may be arranged to trim resistors on opposite sides of a substrate and may reject substrates for reasons other than excess value of the resistor thereon. The apparatus may be arranged to adjust the ratio of the values of resistors on the same substrate. When it is not convenient to isolate the resistor to be trimmed, compensation circuitry can be included in the bridge network.

IPC: B65B11/12
Filed: 1965-11-12
Abstract: 1,113,753. Packaging machines. D. S. O. BLOMET, and G. COINDREAU. 12 Nov., 1965 [19 Nov., 1964], No. 48043/65. Heading B8C. In a machine for wrapping an article having a cylindrical or prismatic cross-section, which is initially rolled up in a wrapper, the projecting ends of the wrapper are folded in against the ends of the article to form radial pleats by a system of circular sector-shaped fingers, radially disposed with respect to the axis of the article, which swing radially inwards against the wrapper to form the pleats between their adjacent straight sides, the adjacent fingers then presenting a complete circular formation of juxtaposed sectors, Fig. 3 (not shown). In the embodiment, a wrapper 15, Fig. 1, is cut from a web fed by rollers 6a, 7 and 9, 10 under the control of a detector 5. A roll of butter 6 is then deposited on the wrapper, situated over an arcuate recess 13, by means of, e.g., a claw-type handling assembly (not shown). A pair of pincers 16, 17 then rises to fold the wrapper round the sides of the roll. After which the partially wrapped roll is conveyed to a further recess 23, where the wrapper ends are formed into pleats 18, 19, 20 &c. by fingers 54, 55, 56 &c. illustrated in their open position in Fig. 2. These fingers, e.g. 55 (58), Fig. 4 (not shown), are pivotally connected at (61) to a piston (64), whose rod (63) extends coaxially with the fingers and is in the form of a toothed rack which co-operates with toothed sectors (59), (60) on the fingers. Finally, the roll is conveyed to a recess 24 where discs 68 are simultaneously rotated and moved axially into contact with the end faces of the roll to fold down the pleats to form a star-shaped closure 21, Fig. 1. The recesses 23, 24 are surmounted by a recessed block 16a, which holds the roll in contact with the lower recesses during the pleating operation.

Title: Supply current modulation device

Abstract: 1413312 Automatic exchange systems COMPAGNIE INDUSTRIELLE DES TELECOMMUNICATIONS CIT-ALCATEL 20 Oct 1972 [20 Oct 1971] 48322/72 Heading H4K Transistor circuity is used to modulate the D.C. line current, without the use of a transformer, so as to provide a false call howler tone to a subscriber that fails to hang up at the end of a call. Fig. 1 shows a known arrangement in which, if either party fails to hang up at the end of a call, a relay F is held operated via the path:- negative supply transformer T, contacts f1, cr2, wire b1-b2, the loop in the sub-set of the subscriber who failed to hang up, wire a1-a2, contact cr1, positive supply. A false call tone is superimposed on the D.C. holding current of relay F via transformer T so as to supply an audible tone to the sub-set in the false call condition. A line circuit in the false call condition can be identified by the presence of positive battery on wire if. Fig. 2 shows the circuit of the invention which replaces the transformer T of Fig. 1. A continuous negative going square wave having a frequency in the audible range is supplied to input E1 and a negative going square wave having a mark to space ratio equal to the on-off periods of the required intermittent false call tone as applied to input E2. Transistor T1 acts as an OR gate and conducts when either input is present, i.e. during the "space" intervals of either input (Fig. 3, not shown). Transistor T2 is switched on when transistor T1 conducts to short out diode D. Because the impedance of transistor T2 when conducting is lower than that of diode D, there is produced at the point S, which is multipled to the line circuits, an intermittent tone signal having a mean D.C. level sufficient to hold on the relay F, the amplitude of the tone being constant and equal to the voltage drop across diode D with transistor T2 non-conducting. This voltage drop may be of the order of 0À775 volts. Diode D may be replaced by a suitable Zener diode.

Abstract: 1400739 Vibratory conveyers REX CHAINBELT Inc 24 Oct 1972 [22 Nov 1971] 48906/72 Heading B8A [Also in Divisions F2 and B1] A vibratory conveyer 1 which is mounted on isolating springs 2 and vibrated by an eccentric weight 3 is provided with at least two spring- tuned inertia weight vibration dampers 8, 9 which can be adjusted to restrict the vibratory motion of the conveyer 1. Each vibration damper consists of an inertia weight 10 mounted by two sets 11, 12 of air springs in a frame 13 attached to the conveyer 1. The circular orbit of the conveyer 1 produced by the eccentric weight 3 acting alone is modified to an ellipse or to straight lines along the axes of the air springs, by varying the air pressure in the sets of springs to tune the dampers 8, 9. For example, to convey to the right the air springs 12 are inflated to such a pressure that the damper is resonant at the drive frequency along the axis of the springs 12. The damper therefore counterbalances the force of the eccentric weight 3 acting in that direction, leaving the conveyer 1 free to vibrate along the axis of the springs 11. The amplitude of vibration is controlled by adjusting the pressure in the springs 11. In Fig 2 (not shown) each inertia weight is hexagonal in cross-section, and there are again two sets of air springs, variation of the pressure of which can result in vibration which is wholly in a vertical plane, or wholly in a horizontal plane. One of the air springs of each set may be replaced by a rubber spring or a coil spring.
