IPC: H05B1/02
Filed: 1923-09-29
Abstract: 207,507. Guy, A. Nov. 25, 1922, [Convention date]. Thermally-actuated valves.-Relates to temperature regulators for electrically-heated appliances of the kind in which a retaining member is normally held in position by solder but releases a spring-actuated member to break an electric circuit when the solder melts. Fig. 1 shows a construction in which an arm 3 is held set by solder in a recess round the pivoting screw 14. A spring-actuated rod 4 carrying a contact 8 and an apertured plate 15 is held in the circuit-closed position by the engagement of a shoulder 5 on the arm 3 with a spring 17 on the plate 15. When the solder melts the arm 3 rotates slightly, allowing the rod 4 and plate 15 to move up and break contact. At the end of the movement the left side of the aperture 16 moves the arm 3'back to its original position where it is re-soldered. The apparatus is re-set by depressing the rod 4, the spring 17 slipping over the shoulder 5. The Specification as open to inspection under Sect. 91 (3) (a) comprises also the modifications shown in Figs. 2 (Cancelled) and 5 (Cancelled), and it is stated that all the regulators may be applied to closing valves in gas-heated appliances. According to the construction shown in Fig. 2 (Cancelled), two members 3, 3<1> are fixed to the sides of a thin metal container 1 containing solder and grip a rod 4 resting in notches 5. When the solder melts the members 3, 3<1> become more resilient and allow the rod 4 to move to the right under spring actuation to break a circuit &c. In its final position the rod 4 is still gripped by the jaws 3, 3<1> which taper so that their distance apart is the same as above. After the solder has solidified, the apparatus is re-set by pressing the rod 4 into its original position. Fig. 5 (Cancelled) shows a modification in which the rod 4 is gripped by a spring-pressed member 3 inserted into the container. This subject-matter does not appear in the Specification as accepted.

Title: Improvements in and relating to lathes, boring mills and the like
IPC: B23Q5/04
Filed: 1944-12-05
Abstract: 587,965. Lathes ; face-plates ; chucks. TAYLOR, S., and REYNOLDS, J. P. Dec. 5, 1944, No. 24317. [Class 83 (iii)] [Also in Group XXIII] A lathe or vertical boring machine in which work is mounted on a rotary faceplate of large diameter adapted to be revolved with respect to a cutting, grinding, or polishing tool has the large diameter work plate formed with a central recess in which is located a coaxial smaller plate, the drive to the larger plate being through a peripheral gear on said plate while the drive to the smaller plate is effected through the inner one of a pair of coaxial spindles on which the plates are mounted. The application of the invention to a lathe headstock comprises an outer spindle 1, Fig. 1, carrying a faceplate 2 with a circular recess for a further faceplate 8 carried on an inner concentric spindle 7. The outer faceplate is provided with an internal ring gear 2a which is driven by a pinion 13 when the dog clutch 24 is engaged with either the low-speed or high-speed driving wheels 28, 29 respectively. A sliding pinion 21 on the end of the driving shaft 16 may be engaged with a wheel 22 driving the inner spindle 7 through the gears 22, 25. Engagement of both the inner and outer spindle drives at the same time is prevented by an interlock 31 for the cluth control levers. The gear wheel 25 is slidable on the shaft 26 and when not in use for driving the inner spindle is moved to engage the gear wheel 10 on the outer spindle for feed drive through the gear wheel 27 and further train (not shown). The shaft 26 is also driven when the inner spindle is in drive and thus drives the feed train through the gear wheel 27. The spindles may be locked together and the drive obtained from the outer spindle gear train by the use of coupling pieces 18, Fig. 2, placed in locking slots 17, 17a provided in the faceplates. When the faceplates are in alignment for the coupling pieces to be placed in position the slots for the jaws are in registration and the jaws may be moved across from one plate to the other. The application of the invention to the spindles and drive of a vertical turning and boring machine is described. The drive for the two faceplates is taken from a single layshaft, a pinion at one end of the layshaft driving an internal ring on the outer faceplate while a pinion at the other end is geared to a pinion on the end of the inner spindle, the driving pinions being coupled selectively to the layshaft by a sliding clutch sleeve.

Abstract: 714,347. Hydraulic intensifiers. DUNLOP RUBBER CO.. Ltd., and TREVASKIS. H. W. Oct. 3, 1952 [Oct. 19, 1951]. No. 24413/51. Class 69 (2). [Also in Group XXXIV] A fluid-pressure operated booster device, e.g. for incorporation in a conventional hydraulic braking circuit, allows normal braking pressure to be led to the brakes via an inlet 4, a supply chamber 8, a spring-loaded inlet valve 14 controlling a passage through a differential piston 7 and normally kept open by its stem 12 abutting a plate 11, a high pressure chamber 6 and an outlet 38. This pressure also acts in a medium-pressure chamber 5a between the ends of the differential piston via a normally open spring-loaded valve 40 controlling a fixed-stem passage 23, a chamber 22 and passage 39, so that a spring 45 maintains the piston in its lower position. When a higher pressure is supplied at 4 and acts in the chamber 6 and outlet 38, it moves a plunger 24 loaded by a spring 34 over the stem 23 to allow the spring 41 to close the valve 40 and the plunger then opens an exhaust valve 27 through stem 26 so that pressure is exhausted from the space 5a and the higher pressure in the supply chamber moves the piston upwardly to close the inlet valve. The piston then moves upwardly still further until a very high boost pressure is produced in the chamber 6 and outlet 38 which acts on the small end of the piston to balance the supply pressure acting on the large end of the piston.

Title: Synthetic resinous products and process for making the same
IPC: C08G12/42
Filed: 1937-09-08
Abstract: In preparing cast resinous products of the urea-formaldehyde type by reacting the components in aqueous solution, removing volatile unreacted material and volatile reaction products in the vapour phase, casting and heat curing, sorbitol is added to the reaction mixture prior to the final vapour phase removal of volatiles.  An addition of 2-20 per cent of the weight of the finished product is suitable.  The concentration may be altered one or more times by vapour-phase elimination of volatiles.  The final vapour-phase removal of volatiles may be effected by adding excess of another solvent and boiling off under atmospheric pressure, spraydrying, or by aspirating with a rapid stream of inert gas.  Urea may be wholly or partly replaced by thiourea or products giving rise to urea or thiourea, e.g. ammonium cyanate may be employed.  Aqueous or gaseous formaldehyde, paraformaldehyde, or hexamethylene tetramine may be employed.  In an example, aqueous solutions of urea and formaldehyde are reacted by heating and the reaction mixture is evaporated under vacuum while air is bubbled through the mixture; after further refluxing, sorbitol is added and a final evaporation under vacuum is effected, after which the liquid is allowed to stand to allow bubbles to rise out of the liquid, cast into porous moulds and cured.  Clear, hard products are obtained which can be turned, cut, sawn and polished.  Waterproofing agents such as castor oil, dyes, pigments &c. may be incorporated.
