Title: Improvements in or relating to laminated springs
IPC: F16F1/18
Filed: 1923-09-26
Abstract: 204,710. Savoye, P., and Marguerite, A. Sept. 29, 1922, [Convention date]. Laminar springs.-In a laminar spring in which some or all of the leaves are composed of juxtaposed wires, the wires are assembled in a clamp, which presses them solidly together, with distortion of parts of the wires to prevent lengthwise movement and also in one or more straps which grip the leaves tightly to minimize the effect of transverse thrusts, in such a way that the number of wire leaves may be increased or diminished and wires may be replaced in case of fracture. The cross-section of the wires may be circular, oval, rectangular, &c. The ends of the wires 1, 2, 3 - -, Fig. 2, constituting the main leaf are bent to form an eye to receive an assembling bolt, or other means of assembly may be employed. The wires of the other leaves may be cut off at their free ends, or the wires 4, 5, 6 may be bent over as shown. The other ends of the wires are held by clamps 22 and are bent upwards, downwards, or to the sides beyond the clamps. Between, the clamps, the wires may be bent round a vertical axis. The wires of the spring are also held together bv straps which leave sufficient play to enable the wires to act independently, such as the strip 15, Fig. 5, which is held in position by the upwardly bent ends of one or two wires 16 fitting in a housing in the strap, or the strap 14, Fig. 6, which is secured by the clamps 22 and preferably has two strap members 20, 21. In the semi-elliptical spring shown in Fig. 5, the centres 7 of the wires are bent out of line and clamped under a stay 12 which fits the bend. In the spring shown in Fig. 6, the rear ends of the wires are bent downwards and housed in a recess 13 in a clamping plate 23, and the ends of the wires of the leaf 9 are bent into an elongated loop to engage a shaft 10, which with the shaft 11 forms part of a suitable holder, thus providing a support if the main leaf 8 breaks. Lubricating material, such as fibre or friction-reducing metal, may be inserted between the leaves, and ordinary solid leaves may form part of the spring.

Title: Improvements relating to screw-cutting lathes and the like
IPC: B23G3/04
Filed: 1923-09-27
Abstract: 220,186. Spurrell, W. Sept. 27, 1923. Turning. - A screw-cutting lathe is provided with a device for indicating the relative positions of the spindle and lead screw, so that in cutting a screw bv a series of traverses the correct instant for re-engaging the tool slide with the lead screw in order to ensure that the tool follows the same path on the work at each cut, is readily determined. The work spindle 7 or other spindle having the same angular speed as the work is provided with an indicator arm 11 adjustably secured by a nut 15 while the lead screw 8 carries a similar adjustable arm 12, the two arms being in the same plane and adjusted so that their tips almost touch when the arms are in alignment, in which position they are set before the first cut. The correct positions of engagement for succeeding cuts will thus be indicated by the alignment of the arms. In a modification, the arms may overlap and one may be arranged to obscure a conspicuous point on the other at the position of alignment. In a further modification, the arm 12 may be dispensed with, the arm 11 coacting with a reference mark on the wheel 10. In another modification, Fig. 4, the arm 12 may be replaced by a plate 17 carrying a trigger 19 which is operated by the arm 11 so that a striker 38 rings a bell 27 to give audible warning to the operator. In a modification of this arrangement the trigger may operate a visible signal such as a semaphore arm.

Title: Improvements in web supply mechanism for printing presses and other machines
IPC: B65H19/18
Filed: 1933-01-02
Abstract: 417,500. Feeding webs. HOE & CO., Ltd., R., 109, Borough Road, London.-(Assignees of Tomlin, J. R., Lundquist, A., and Horton, A. J. ; 138th Street, New York, U.S.A.) Jan. 2, 1933, No. 24132/34. Convention date, March 3, 1932. Divided out of 417,443. [Class 100 (i).] A web-renewing mechanism for printing-presses and other machines comprises a support carrying a running roll and a reserve roll and adjustable to suit rolls of different widths, an electrically operated web deflector for pressing the expiring web against the reserve roll, a timing device rotatable with the reserve roll, conductors completing the circuit through the timing device and the means for operating the deflector, and mechanism for taking-up or paying-out the conductors when the support is adjusted. The mechanism described is identical with that described in Specification 417,443. The running and reserve rolls 28, 29, Fig. 1, are mounted between a pair of arms 11 adjustable in accordance with the width of the rolls upon spaced shafts 8, 81 carried by members 7 having spindles 6 mounted in pedestals 5. One of the spindles 6 carries a gear wheel 16 adapted to be driven by an electric motor 22 to rotate the support to bring the rolls from loading position to the normal running position which is that occupied by the roll 29. The roll surfaces are engaged by fingers 23 secured to shafts 25 rotatable in the members 7. When a running roll in normal running position is reduced to a certain diameter, its finger 23 closes a switch to start the motor 22 to bring the reserve roll into running position. The fingers 23 are adjustable along their shafts to suit rolls of different widths. The running web is pressed against the reserve roll upon the de-energization of a magnet 48 which occurs upon the closing of a circuit which includes a timing device on the spindle of the roll and contact segments carried by one of the spindles 6. The timing device comprises a contact segment rotating with the roll spindle and adapted during its rotation to bridge a pair of brushes mounted on the roll-supporting arm 11. The brushes are connected to the contact segments carried by the spindle 6 by flexible conductors, and, to prevent slack in these conductors when the arm 11 is adjusted, the take-up mechanism shown in Fig. 25 is provided on the arm 11. The conductors from the brushes, and from a similar pair of brushes of the timing device at the other end of the arm 11, are taken to a junction box 184 from which a four-conductor cable 185 is led round lower and upper sheaves 187, 186 and thence round a guide pulley 188 to an anchorage on the adjacent member 7. The cable is also anchored near the junction box 184 by means of a clamp 189. The sheaves 186 are mounted on a fixed stud 191 and the sheaves 187 on a stud 192 carried by a head 193 slidable on guide rods 194. Springs 197 on the rods urge the head 193 in a direction away from the sheaves 186. Specification 417,499 also is referred to.

Title: Improved manufacture of transparent soap
IPC: C11D13/00
Filed: 1932-08-30
Abstract: Transparent soaps of high fatty acid content, e.g. 70-75 per cent, are made by saponifying the usual mixtures of fats of a high degree of purity with resin by means of alkali of a high degree of purity, rapidly cooling the hot fluid soap in a thin layer to atmospheric temperature, drying in air at atmospheric temperature to such an extent as to avoid supersaturation, milling cold, compressing and forming the rope into pieces as desired.  Fillers, e.g. glycerine, alcohol, sugar, soda, are preferably omitted; and the use of castor oil, palm nut oil, or castor oil is not essential.  In an example, 61 kg. of tallow, 18 kg. of coco nut oil, 11 kg. of castor oil, and 10 kg. of resin is saponified with 45,8 kg. of 39 DEG  B<\>ae soda lye; the transparent soap paste is cooled on rollers in 2-3 seconds from 90-100 DEG  C. to about 20 DEG  C., the ribbons or plates scented, milled once or twice on cold rollers, passed through a press or plodder having a cooled head and operating at about half the usual speed.

Title: Improvements relating to arrangements for the generation of control impulses
IPC: D01H5/36
Filed: 1957-07-31
Abstract: <PICT:0818809/IV (a)/1> In spinning machinery, a mechanism for supplying the impulses controlling a pump supplying the additional spinning solution for the slubs or knops on artificial threads having a fluctuating count comprises a driven disc 14 driven at a constant mean speed of rotation from a driving shaft 3 but at a cyclically varying speed of a predetermined frequency.  Gears 8, 9 on the shaft 3 drive gears 11, 12 respectively freely mounted upon a shaft 10, at different speeds.  Pivoted at 25 on the gear 12 is a disc 13 having a follower pin 26 engaged in a cam groove 27 of the gear 11 and a coupling by means of a slot 30 with a pin 28 secured to the driven disc 14, the pin 28 passing through an arcuate slot 29 in the gear 12.  Thus the disc 13 is oscillated due to the difference of the speeds of gears 11, 12, which oscillation is imparted to the driven disc 14 about the mean speed of rotation thereof which is determined by the gears 9, 12.  Coupled to the disc 14 is a contact disc having a part 31 adapted to convey a pump controlling impulse electrically, magnetically or mechanically.  The impulse may be further transmitted through relays or hydraulically or pneumatically.  A number of such devices may be operated in parallel for generating an irregular succession of impulses having the same average frequency over a long period.
Patent GB-710290-A (GB)
Title: Improvements in or relating to methods of making silica-alumina catalysts
IPC: C10G11/04
Filed: 1951-10-18
Abstract: Silica-alumina catalyst is prepared by forming a silica hydrosol by contacting a dilute solution of sodium silicate with an acid regenerated cation exchange material, raising the pH of the hydrosol to hasten its gelling and form small hydrogel particles suspended in water, mixing the suspension with a water slurry of alumina, and removing and drying the silica-alumina particles.  The slurry of alumina may be obtained by hydrolysis of an aluminium alcoholate solution as described in Specification 663,128; part of the slurry may be filtered and the filter cake mixed with the rest of the slurry.  The sodium silicate solution is passed upwardly or downwardly through a bed of the exchange material which is periodically regenerated with dilute acid; suitable exchange materials are made from sulphuric acid-treated coal, wood, waste petroleum sludge or lignite; synthetic resins or "Amberlite" (Registered Trade Mark) resins may be used.  The silica hydrosol is mixed in a mixing nozzle with ammonium hydroxide to anhydrous ammonia to bring the pH to between about 4 and 7, and agitated to form small hydrogel particles.  After mixing with the alumina, the slurry may be sprayed into the top of the tank containing a petroleum oil fraction at 150 DEG -200 DEG F. in order to form spherical particles; alternatively the slurry may be spray dried or may be filtered and the cake dried and ground.  The catalyst is suitable for use in cracking hydrocarbons. Specification 645,703 also is referred to.

Title: Improvements in reversible share ploughs
IPC: A01B3/16
Filed: 1934-08-24
Abstract: 438,746. Implements for working land. RANSOMES, SIMS, & JEFFERIES, Ltd., CHALLACOMBE, A., and BROWN, R. A., Orwell Works, Ipswich. Aug. 24, 1934, No. 24481. [Class 6 (i)] In a reversible plough having right and left hand plough bodies mounted on a beam structure adapted to turn about an axis to effect reversal of the plough bodies, the rotation being utilized to raise the beam structure relatively to two wheel standards which are independently movable vertically under control of latches, so as to cause the appropriate wheel to move into position to act as a furrow wheel for right or left hand ploughing, means are provided for operating the two latches manually by a single chain, cord, or lever, the same means being adapted to operate a stop to release the beam structure ready for reversal of the plough bodies. The beam structure 3 is mounted on an axle 4 on a draught frame 5 and is normally prevented from turning by a stop 6. The wheel standards 9 slide in sleeves 10 on the frame 5. Each pivoted latch 11 has two hooks 12, 13 to engage a pin 15 carried by arms 16 pivoted on a bracket 18 on the sleeve 10 and adjustably connected by links 19 and a lever 20 to a bracket 22 on the standard 9. The hooks 12, 13 engage the pin 15 when the wheel 7 is acting as furrow wheel and transport wheel, respectively. When the wheel 7 acts as a land wheel the pin 15 engages a bell-crank lever 24 which is adjustable, to regulate the depth of work, by means of a screw 26. Both latches 11 are tripped by pulling on a cord 43 and thus moving a ratchet lever 34 which rotates a cam shaft 30 through spur gearing 39, 36, each pull movement of the lever rotating the shaft 30 through 90‹. There are two unequal cam arms 31, 32 for each latch, the short arm for one latch coming into operation simultaneously with the long arm for the other latch and vice versa. The lever 34 passes through a slotted guide and is controlled by a spring. The stop 6 for the beam structure is pivoted and normally held in place by toggle levers and a spring. It is moved by the engagement of one of two cam arms on the shaft 30 with one of the toggle levers. Backward rotation of the beam structure is prevented by a pivoted latch above the stop 6. Each standard 9 may be connected to the draught frame 5 by a spring 56. It may normally be prevented by a key from rotating in the sleeve 10, being however free to castor when the wheel 7 is in transport position. In a modification the latch-pin 15 is adjustably connected to the bracket 22 by an adjustable screw connection.
