Filed: 1924-05-14
Abstract: 234,977. Buckle, H. L. T., and Gramophone Co., Ltd. May 14, 1924. Reproducing-devices, arranging and supporting. -Relates to sound-reproducing machines in which a large diaphragm mounted in a supporting frame replaces the usual sound-box tone-arm and horn, and in which a rod substantially parallel to the diaphragm transmits the vibrations of the stylus to the centre of the diaphragm. According to the invention the stylus-holder is mounted at or near to the edge of the diaphragm, which itself is adapted to rock about a point diametrically opposite to the stylus-holder (or thereabouts) so that it is free to move both horizontally and vertically. The plane of the diaphragm may be inclined to that of the record when the machine is in use, and the mounting is preferably such as to allow the diaphragm to be moved close to and approximately parallel with the turntable when out of action. In the construction shown, the diaphragm 1 in its ring 2, to which is attached a spider 8, is pivoted on an horizontal axis formed by pivot screws 13 carried by lugs 11 on a plate secured to the spider, the screws engaging in the ends of a short transverse rod fixed at the upper end of a pillar 16. This is rotatably mounted on a stem 17, rigidly attached to a plate 18, which is pivoted between screws 19. The stylus-holder 4, which is preferably of the type described in Specification 202,488 is mounted near the part of the edge of the diaphragm-ring opposite to the pivotal support. The pressure of the stylus upon the record is variable, being determined by the position of a spring 29 upon which the diaphragmholder rests; ,the spring is mounted on an adjustable collar 28. The diaphragm can be moved from the inclined playing position shown in Fig. 1 to that shown in Fig. 2 by pulling it forward after raising the needle, the parts 16, 17, 18 swinging about the pivots 19. A leaf spring 31' serves to maintain the plate 18 and the parts carried thereby in either position. Specification 11015/09 is referred to in the Provisional Specification.

Patent GB-586164-A (GB)
Title: Improvements in control devices for the heating and crystallization of masses
IPC: C13B25/06
Filed: 1944-06-27
Abstract: <PICT:0586164/III/1> In a crystallization pan the flow of liquor into the pan is controlled according to the temperature difference between a source of constant heat emission within the pan and a point in the liquor adjacent thereto.  As shown applied to sugar crystallization, a vacuum pan 1 of the calandria type has situated in the downtake 3, a thermometer bulb 9 and an electric heating unit 8 which has a temperature sensitive element 13 associated therewith.  The two elements 9 and 13 are connected to recording instruments or alternatively to a temperature difference recording instrument 32 which may serve as the basis for manual control. The heat from the resistance will be conducted away at a rate depending on the state of the liquor, with a consequent change of the temperature difference recorded.  When the liquor is initially drawn into the pan it will be thin and the temperature difference will be high.  As the liquor is heated a steep line will result on the graph until graining takes place, after which there will be a gradual rise as the liquor thickens and the pan fills up.  An indicating arm (Fig. 4) may be arranged to make contact 33 when the temperature difference rises and contact 34 when it drops. This causes the opening and closing respectively of the liquor feed valve 5.  By this means the temperature difference would be kept constant but as a rising characteristic is required the contact arm 35 is connected to a liquor level indicator 36, which moves the contact arm 35 to give the desired rising characteristic to the control.  This indicator may be adapted to control the steam valve 7 and the vapour valve 41.  The liquor valve may be controlled by a compressed air relay and a fluid pressure motor.

Title: Improvements in or relating to timber connectors and machines for making the same
IPC: B21G3/00
Filed: 1970-03-13
Abstract: 1,269,903. Making timber connectors; bending; roller feeds. AUTOMATVE BUILDING COMPONENTS NEW ZEALAND Ltd. 13 March, 1970 [14 March, 1969; 2 Feb., 1970], No. 12162/70. Headings B3A, B3E and B3W. [Also in Division F2]  A machine, Fig. 2, for making a wire timber connector, Fig. 1, having end spikes 2 and 3 at an angle between 8 and 15 degrees, preferably 10 degrees, less than a right angle to a central portion 1 and lying in mutually perpendicular planes, comprises an intermittent wire feed 12, a shear 22 for pointing the ends 4 of the wire as it cuts it to length, a cylinder 27 carrying forming dies 35 which receive lengths of wire in a groove 36, means 44 for straightening the ends of a length of wire, spring loaded rollers 54, for bending the wire into a U shape, on each side of the cylinder 27 and means for twisting the U- shaped wire into the shape shown in Fig. 1. The shear is actuated by a cam 25 on the face 20 of a cam plate 32 which rotates a number of times equal to the number of equispaced dies 35 on the cylinder 27 for one rotation of the cylinder 27. The cylinder 27 is moved by a ratchet 28 driven from a shaft 30 which also drives the cam plate 32. A second drive shaft drives the feed rollers in timed relation to the cam plate. The feed is by a roller 12 having a raised segmental surface (13), Fig. 7 (not shown) which surface pinches the wire 7 between itself and a second roller surface (19) to produce an intermittent feed. The twisting is effected by turning the U- shaped wire workpiece so that both limbs project radially then holding one against one end of the die 35 while a roller (60), Fig. 6 (not shown) engages the other causing it to be twisted through a right angle.

Patent GB-708934-A (GB)
Title: Improvements relating to dyeing of animal textile fibres
Inventor: KILBY WILLIAM
Filed: 1951-05-25
Abstract: In the dyeing of wool and other animal fibres with vat or sulphur dyestuffs, the fibres impregnated with the dyestuff and an aqueous alkaline reducing liquor are heated in the presence of an organic ester, the ester being hydrolysed by the hot alkali, and the acid so produced serving to neutralize the caustic alkali on the fibres.  The dyeing operation is preferably continuous, heating being effected by passing the impregnated fibres through molten metal, as described in Specification 620,584, or through hot oil, or steam.  The ester, e.g. n or isopropyl acetate, ethyl lactate or diethyl tartrate, may be added to the cold alkaline reducing liquor containing the dyestuff. Alternatively, the fibres may be impregnated with the ester, dried and then impregnated with the heated alkaline reducing liquor containing the dyestuff, or the fibres may first be passed through a pigment liquor containing the ester, dried and then passed through the heated reducing liquor containing the alkali.  In examples, additions to the dye liquor are sodium silicate, glucose and wetting agents, and in one example a wool-cotton union fabric is treated.

Patent GB-1479094-A (GB)
Title: Ring trip detectors
IPC: H04M3/22
Filed: 1975-03-25
Abstract: 1479094 Ring trip circuits STANDARD TELEPHONES & CABLES Ltd 25 March 1975 12370/75 Heading H4K A ring trip circuit utilizes a Hall effect device and may be combined with a loop supervision circuit. The ring trip arrangement, Fig. 2, is similar to the loop detector of Specification 1,478,219 in that a micro processor MP supervises a plurality of Hall Effect devices HED. When a subscriber is rung, ringing current is supplied via the winding HED of a Hall effect device individual to the subscribers line. The output of a Hall Effect element HS, positioned in an air gap of a magnetic circuit on which the winding HED is wound, is coupled via a threshold circuit OP 1  OP 2  to the microprocessor. A pulsed control current is supplied to the control inputs of the Hall effect element via transistor T and with only A.C. ringing current present in the winding HED, the threshold circuit produces a zero output. When D.C. flows in the winding the output of the element HS is increased and an output signal is supplied via the threshold circuit to the microprocessor each time the pulsed control current is applied to the element. An up-down counter is used to count the number of successive applications of pulse control current for which the line is found looped and a valid loop is assumed after a predetermined count is reached. Fig. 4 shows a multi-winding Hall effect device which is used for both ring trip and loop supervision. To apply ringing, relay RN is operated to connect the upper winding of the device into the loop. A continuous control current is applied to the element HS and when the threshold circuit OP 1 , OP 2  produces an offhook indication relay RN is released to couple a pair of balanced windings of the device HED to the respective line wires. Threshold circuit OP 1 , OP 3  then produces a line looped indication until the subscriber goes on-hook. The three winding arrangement of Fig. 4 is only necessary in systems where D.C. polarity reversals occur. It is also said to allow an intercept circuit elsewhere in the system to perform a ring trip function without causing the loop supervision circuit to operate, by its applying a- 50V signal via a resistor to the negative wire of the speech pair. Fig. 3 (not shown) illustrates a combined ring trip and loop supervision circuit for use where polarity reversals do not occur, the operational amplifier OP 3  and one of the windings of the device HED being omitted. The processor may be as described in Specification No. 1,448,041. Integrated circuits may be used for the threshold circuits. Attention is directed to Specification No. 1,450,743 and Specification 1,478,219 which claim similar arrangements.

Title: Improved vehicle braking means
IPC: B61H1/00
Filed: 1926-05-14
Abstract: 275,347. McMahon, J. May 14, 1926. Actuated by relaxation of pull; actuated by springs; band or coil. - Brakes for railway vehicles and the like adapted to be released on the vehicles being hauled and also adapted to be manually operated comprise a rope 12 encircling the brake bands 4 of drums 1 mounted on the wheel axles, the rope being connected to the ends of the vehicle and adapted to be tightened by a sliding bar 10, to apply the brakes. Slidable racks 23<a> are connected to the rope 12 by ropes 23 and to the bar 10 by springs 16. The brakes are set by moving the bar 10 by manual operation of a rack 25 so that a pin 40 can be passed through the bar to hold it in position. By this means one of the springs 16 is extended causing the rack 23a to which it is connected to slide and tighten the rope 12 and apply the brakes. On the commencement of hauling a connection 21 to the vehicle in front moves an arm 20 and turns a toothed wheel 18 meshing with the rack 23a so as to slide the rack and release the brakes. A pinion 26 operating the rack 25 is mounted on a shaft extending across the vehicle and having a handle at each end, one of which carries a tooth adapted to be held when the brakes are set by a toothed quadrant on the end of a transverse slidable bar 31. A keyway in the bar 31 and pins passing through the quadrant prevent turning movement. This bar is provided with handles at each end so that it may be moved against spring pressure to disengage the tooth so that the brakes may be returned to inoperative position by the spring 16, when the pin 40 is removed. The brake bands 4 are provided with wooden blocks 4a and are normally expanded by springs encircling a member 6 having a U-shaped cross section, inserted in the ends of the bands 4 or blocks 4a and secured by pins passing through slots in the member 6. The weight of the band is borne by a loop 9 of coiled spring formation passing round the bar 10 and the member 6. A guide roller 14 keeps the ropes clear of one another. In a modification the ropes are connected directly to the sliding bar upon which the racks are fixed and a rigid coupling is provided between the arm 20 and the preceding vehicle. Springs attached to a cross member of the vehicle retain the bar 10 in central position. Foot levers at each corner of the vehicle are connected by ropes to arms on a cross shaft carrying a pinion meshing with a rack on the bar 10. This cross shaft carries an arm and a tooth adapted to engage the tooth quadrant. A hook is provided to hold the quadrant inoperative when necessary. A turnbuckle 15 provides adjustment.
