Title: Improvements in pile hammer operable with either diesel or drop hammer effect
Inventor: FREDERICK LEONARD LONG
IPC: E02D7/12
Filed: 1959-02-24
Abstract: 846,844. Pile drivers. McKIERNANTERRY CORPORATION. Feb. 24, 1959, No. 6369/59. Class 68(2). A diesel pile driver is provided with means operated by a single hoist line for either lifting the piston within the cylinder or alternatively lifting the piston and cylinder together for use as a drop-hammer. The machine comprises a cylinder which has an upper guide part 15 and a lower working part 16, a piston 18 and a supporting framework 17. The lower end of the cylinder is closed by a concave block 19 which forms a compression ignition chamber for diesel operation. To start the diesel action the piston is raised by a hoisting block 22, running in a guide 23, by means of a catch 25 pivoted to the block and which engages under a shoulder 28 at the top of the piston. The catch is moved into and out of engagement with the ram by a trigger 33 which engages with abutments on the cylinder. The lower abutment 34 raises the trigger 33 and through the toggle links 31 and 30 swings the catch-25 under the shoulder 28. At the top of the guide cylinder the trigger engages the abutment 35 and withdraws the catch from under the shoulder 28 to release the piston. The movement of the toggle links is limited by the pins 36 and 37. If the block is hoisted beyond the position at which the piston is released it engages a stop 40 on the frame and the piston and cylinder are then raised together for use as a drophammer. In a modification a spring-loaded detent (not shown see Figs. 12 and 13) is provided to locate the toggle links in their extreme positions. In a further modification the hoisting block 22 can be locked to the guide 23 by a pin, for convenience in transport.

Title: Light sensitive circuits
Inventor: HARTLEY HENRY FREDERICK
IPC: A23L3/26
Filed: 1961-02-22
Abstract: 1,010,201. Light-sensitive circuits. ROTAX Ltd. Feb. 7, 1962 [Feb.22,1961], No. 6436/61. Heading G1A. [Also in Division H3] A light-sensitive circuit comprises an electronic amplifier such as a transisitor 4 connected across a D.C. supply in series with an electromagnetic device 6 and a lamp 5 and having a photoelectric cell 3 such as a phototransistor connected to its control terminal, the arrangement being such that when the photo-electric cell is not illuminated the amplifier is non-conductive but when the cell is illuminated current flows through the amplifier to illuminate the lamp. The lamp 5 when illuminated, being in close proximity to the cell increases the amount of light falling on the cell, this regenerative action causing the current flowing through the amplifier to build up to a value sufficient to operate the electromagnetic device 6. When the initial source of illumination is removed the control effected by the cell reduces the current flowing through the lamp until by degenerative action the amplifier ceases to conduct, and the electromagnetic device ceases to operate. A triode may be used in place of the transistor 4. The device 6 may be a solenoid used for tilting the driving mirror of a road vehicle when the mirror is illuminated by the headlamps of a following vehicle, or it may be used as an automatic parking or dipping switch for vehicles.

Title: Improvements in or relating to automatic or semi-automatic telephone or like systems
IPC: H04Q3/00
Filed: 1933-10-06
Abstract: 426,865. Automatic exchange systems. STANDARD TELEPHONES & CABLES, Ltd., WRIGHT, E. P. G., HARTLEY, G. C., and REYNOLDS, W. J., 63, Aldwych, London. Oct. 6, 1933, No. 6533/35. Divided out of 426,790. [Class 40 (iv)] If all outlets of a wanted numerical group, e.g. junctions to another exchange are busy, a recall circuit is seized and a calling subscriber wishing to be recalled when an outlet becomes free must first dial an extra digit (1) and may then hang up. The invention is applied to the system described in Specification 426,790 in which calls to the manual board and the automatic equipment at a main exchange are routed over the same group of junctions in response to digits 0, 9, respectively, the recall feature being only available for calls to the manual board. The recall circuit, Fig. 2, is connected at the end of the group of mainexchange junctions and is marked busy except when digit 0 has been dialled. If all junctions are busy under these circumstances the recall circuit is seized, and relays A, B operate and connect busy tone BT. If the calling subscriber wishes to be recalled when a junction is available he dials the digit 1 before hanging up. Relays X, Y operate at the break and make of the impulse, respectively, and when the receiver is hung up, A, B release, X reoperates, and Y remains held over the test wire T and places battery on the a-wire to hold the selector. When a junction becomes free JA (or JB &c.) operates from ground placed on lead FL, places ground on lead TL to seize the junction, and connects ringing current back to operate a relay in the group-selector which in turn rings the calling line. When the subscriber replies, relay F responds and the connection is switched through to the manual board at the main exchange. If the calling subscriber wishes to cancel the call after hanging up and before being recalled, he may do so by lifting his receiver and replacing it when A operates to release Y and X. A modification is referred to in which the recall circuit is not used during conversation, but is associated only with the bank of a discriminating and marking switch associated with the group selector, and is released when a junction becomes available.

Title: Improvements in and relating to the feeding of flat-folded bags to a filling machine
IPC: B65B43/12
Filed: 1961-02-24
Abstract: 934,268. Feeding sheets. A. WINDMOLLER, and M. GENNERICH, [trading as WINDMOLLER & HOLSCHER]. Feb. 24, 1961 [Feb. 24, 1960], No. 6946/61. Class 100 (1). In apparatus for feeding flat-folded bags to a bag-filling machine, each bag is fed in a circular path with the base of the bag leading, the bag is arrested and located in a plane inclined to the vertical, and is then fed in a lateral direction by means which is accelerated to a predetermined speed, and the bag is transferred to further means travelling at that speed and which feeds the bag to the filling machine. As shown, flat-folded bags 1 from a stack or a bag-making machine are advanced along a circular path by a narrow cylinder 3 provided with grippers 2 and deposited, base downwards, on a stop 5 which embraces the cylinder. The stop 5 is adjustably mounted on a holder 6 to suit different lengths of bags, and each bag rests on a plate 9 which is inclined to the vertical; air jets from a pipe 10 assist in locating of the bag on the plate 9. The plate 9 is secured to bars 15, 16 which are slidably mounted in the machine frame and are reciprocated in a direction parallel to the axis of the cylinder 3 by means of a linkage operated from a cam-plate 31 (not shown). The plate 9 is accelerated from rest to a maximum speed, at which it is taken by grippers 37, 38 travelling at the same speed and in the same direction, then decelerates to zero, speed, and thereafter returns to starting position. There are several sets of grippers 37, 38 carried on an endless chain 36 mounted on two sprocket wheels provided with means for closing and opening the grippers, respectively, and the bags are released at the bag-filling machine.

Title: Control valve assemblies for air braking systems
IPC: B60T8/46
Filed: 1973-02-13
Abstract: 1460146 Valve assemblies; anti-skid compressed air systems; valves GIRLING Ltd 21 Jan 1974 [13 Feb 1973] 6958/73 Headings F2F and F2V A pneumatic anti-skid braking system incorporates a control valve assembly comprising a normally closed first valve 7, 12 controlling communication between an inlet 5 and a first outlet 6 connected to the high pressure side of an actuator 34; a second valve 16, 12 controlling communication between the first outlet 6 and a second outlet 10 connected to the low pressure side of the actuator 34; and a diaphragm 19 whereof a chamber 20 at the upper side is exposed to braking pressure from the reservoir 32 when a valve 33 is operated whereby the diaphragm 20 is moved down to close the second valve 16, 12 and open the first valve 7, 12 to connect the reservoir 32 to the high pressure side of the actuator 34 to apply the brake. The lower side of the diaphragm 19 is then exposed to the pressure from the reservoir 32 but the effective area of the upper side of the diaphragm 19 including head 18<SP>1</SP> is larger when valve 16, 12 is closed so that there is a nett downward force to keep valve 7, 12 open: in the event of the deceleration of the braked wheel exceeding a predetermined value, however, a solenoid device 30 is actuated by a skid signal to vent the chamber 20 to atmosphere whereby the diaphragm 19 moves upwardly to close valve 7, 12 and to open valve 12, 16 to connect outlets 6, 10. The high and low pressure sides of the actuator 34 are thereby connected to reduce the braking pressure, the pressure in the low pressure side decaying via a restrictor 35 to atmosphere. When the skid signal terminates, the pressure in reservoir 32 is again applied to chamber 20 but this pressure now has to oppose the pressure remaining in the actuator 34 acting over the under-side area of diaphragm 19 and the area of head 17 whereby the second valve 12, 16 will close relatively quickly but the first valve 7, 12 will open less quickly and less fully than normal, and the pressure supplied to the high pressure side of actuator 34 will have to act against the pressure remaining on the low pressure side; thereby a greatly reduced braking pressure is applied on the second cycle of antiskid operation. In the embodiment of Fig. 1 passages 24, 21 connect inlet port 5 to chamber 20 but when solenoid device 30 is energized a valve 23, 28 is closed to disconnect passages 24, 21 and to connect passage 21 and hence chamber 20 to atmosphere via a passage 31 in a plug 25. In the embodiment of Fig. 2 (not shown) the reservoir (32) is connected directly to the inlet (5) and via the pedal valve (33) with a further inlet (37)-passage (24) is omitted.

Abstract: 1388829 Crimping fibres IWS NOMINEE CO Ltd 6 March 1972 [16 March 1971] 7007/71 Headings DIF and D1S A method of crimping fibres comprises forwarding and flattening a strand or layer of fibres 100 between a feed roller 10 rotating at a first surface speed and a curved guide plate 11 closely spaced from and conforming to the surface of the roller 10, and discharging the flattened layer from the opening defined by the roller 10 and the end of the plate 11 into a folding zone where the layer is unsupported and thence directly between a pair of spaced substantially parallel conveyor belts 20, 21 driven at a second surface speed slower than the first speed, whereby the layer of fibres becomes folded at least in part normal to the plane of the layer, the amplitude and pitch of the folds being dependent on the spacing between the conveyor belts and the relationship between the first and second speeds. The folded fibrous layer is preferably subjected to a steam treatment, at the intake to the conveyor belts, by means of steam pipes 26, 27 having orifices for the ejection of steam. The folded layer may be subjected to a steam treatment at 28 and hot-air drying treatment at 29 while held between the conveyor belts. The position of the guide plate 11, which is preferably S- shaped, is adjustable relative to the roller 10, and also the roller 10 is made adjustable relative to the intake of the conveyor belts 20, 21. The guide plate 11 and feed roller 10 may be mounted on a frame for movement together into and out of the operative position; or may be separately mounted for independent movement. The conveyor belts 20, 21 are preferably permeable e.g. wire mesh belts. The fibres are preferably wool fibres and may have a setting agent applied before folding. The fibres are supplied in the form of a sliver 100 which is flattened between the roller 10 and guide plate 11 to produce a layer of fibres. Folding in the plane of the layer may also occur.
