Filed: 1926-08-13
Abstract: 268,209. Marks, E. C. R., (Williams Oil- O-Matic Heating Corporation). Aug. 13, 1926. Liquid fuell supply.-Liquid fuel is pumped from a storage tank 7 to two enclosed chambers 3, 4 containing steam or hot water cylinders 15 for maintaining the fuel at the required temperature. Two pipes lead from adjacent the top of the chamber 3, one pipe 8 leading to the lower part of an open bottomed cylinder 17 arranged in the tank 7 and the other pipe 9 to the suction side of the pump 6. The chamber 4 contains three pipes, one pipe 2 leading from the bottom of the chamber to the burner 1 and the other two pipes 10, 11 leading from the top of the chamber to the top of the cylinder 17 and to the delivery side of the pump 6 respectively. The pump 6 is operated by an electric motor 5 having a float-operated switch 12 which normally stops and starts the motor when the fuel in the chamber 4 rises or falls to predetermined levels. If, however, when the fuel is at its upper limit in the chamber 4, the fuel within the cylinder 17 falls below a predetermined temperature, a thermostatic element 19 operates a switch to close an independent circuit to the motor terminals and the pump circulates the fuel through the chambers 3, 4 and cylinder 17 until it reaches the temperature at which the switch is operated to open the circuit. The element 19 may contain an expansible liquid liquid seal being provided for the pump 6. In tube apparatus 18. A small orifice in the pipe 9 adjacent the bottom of the chamber 3 ensures a liquid seal being provided for the pump 6. In a modification the heating cylinders 15 are replaced by electric heating coils in circuit with the thermostat.

Title: Improved combined ordinary latch and night latch
IPC: E05B55/06
Filed: 1949-07-21
Abstract: 655,418. Latches. PARKES & SONS, Ltd., J., and BUTTER, F. J. July 21, 1949, No. 20311/48. [Class 44] In a combined ordinary latch and night latch consisting of a single spring bolt 1 which may be retracted from either side of the door by independent knob-operated followers 6, 13, and also by a key-operated one 14 from the outside, the follower 6 which is operated by the inside handle actuates the latch bolt 1 directly, whilst the other followers 13, 14, rotate follower 6 through a lever 10 pivoted on a pin 8 thereon. The latch bolt 1 is retracted by follower 6 acting on one of a pair of lugs 3 on the bolt. Full projection of the bolt is prevented by a spring-pressed pawl 7 engaging a tooth on follower 6, but on the bolt being pressed in by the striking plate on closing the door, the rear end of the bolt tail disengages the pawl 7 to allow the bolt to project further and the pin 8 on follower 6 enters an aperture 9 in the bolt to deadlock it. On operating the outside handle, follower 13 lifts the lever 10 mounted-on pin 8 and rotates the follower 6 to retract the bolt. Similarly key rotation of an exterior cylinder lock causes follower 14 to rotate a lever 15 and lift lever 10 for retracting the bolt. On rotating the cylinder in the opposite direction the follower 14 moves a dog 16 into the path of the bolt 1 to prevent operation by the inner handle, and a link 17 which is pivoted to a crankarm of dog 16 rocks the lever 10 out of the path of the follower 13 to prevent outside handle operation. To prevent retraction of the bolt by follower 13 but allow operation by follower 6, a lever 20 is connected to a pair of plungers 18, 21, whose ends abut lever 10 to rock it clear of follower 13, and which are operable from the front end of the lock case. The invention may be applied to mortise or rim latches.

Title: Polycarbonamide from hexamethylene diamine and 2, 2-bis-(carboxyphenyl) propane
IPC: C08G69/26
Filed: 1954-07-13
Abstract: Polyamides are prepared from hexamethylene diamine and 2,2-bis(m- or p-carboxyphenyl)-propane or a mixture of the isomeric acids which contains not more than 30 per cent of the bis-meta isomer.  The 2,2-bis-(carboxyphenyl)-propanes may be prepared by the methods disclosed in Specification 753,384.  The products do not crystallize on heating in air at 150 DEG  C. for long periods.  A chain length regulator, e.g. a monocarboxylic acid, such as acetic, benzoic, naphthenic or naphthoic acid, an acid anhydride, a primary or secondary amine or a small excess of one of the reactants may be present during the reaction.  A polymerization catalyst, e.g. phosphoric acid, may also be added. Amide-forming derivatives of the acid reactants, e.g. esters, acid chloride, or anhydrides, may be used.  Stabilizers and/or antioxidants may be added to the products as described in Specifications 708,029 and 715,364.  In the examples: (1) hexamethylene diamine and 2,2 - bis - (p - carboxyphenyl) - propane were heated in a sealed tube in nitrogen to form a low molecular weight polymer which was then heated in a stream of nitrogen with removal of water with final heating under reduced pressure.  The bis-meta isomer of the acid or mixtures of the two isomers may be employed.  In Example 3 the dimethyl ester of the acid is employed and in Example 4 the salt of the diamine and acid is formed before polymerization and the effect on the final molecular weight of varying proportions of acetic acid is determined.  The physical properties of the products are compared with those of other polyamides.  The products may be obtained crystal clear and used in windows, lenses, reflectors and are also suitable for electrical insulation, kitchenware handles, decorative purposes, sheets or solid forms.  Colours or fillers, e.g. glass, colloidal silica or carbon black may be added.

Abstract: 783,366. Automatic circuit-breakers. I.T.E. CIRCUIT BREAKER CO. July 22,1955 [Oct. 11, 1954], No. 21314/55. Class 38 (5). A low-voltage, high-current, polyphase circuit-breaker has bimetallic tripping means 24 to cause the opening of the circuit-breaker contacts 12, 13 with a time delay in response to excess current up to a lower predetermined value, selectromagnetic tripping means 70 to cause the opening of the contacts without delay in response to excess current above the lower value and fusible current-limiting means 25 which immediately disconnect the controlled circuit and cause the opening of the contacts in the event of excess current above a higher predetermined value. In the arrangement shown, on moderate overloads, the bimetal 24 deflects and by means of a screw (not shown) turns a latch 78a clockwise about a fixed pivot 83. The latch 78a releases a lever 77 which under the bias of a spring (not shown) rotates clockwise about a fixed pivot 75 and forces down a member 54 to turn a trip-bar 16 common to all the phases. In the event of a higher fault current, the current in a single turn winding 64 magnetizes a core 70 sufficiently for an armature 72a carried by the member 54 to be attracted so as to turn the trip-bar without delay. Under severe short-circuit conditions, the device 25 fuses to open the controlled phase and at the same time forces out a plunger 30 which turns the latch 78a to cause tripping of the circuitbreaker. The circuit-breaker is provided with a common operating-mechanism (indicated at 20) for the contacts in all the phases and each phase has the three tripping means shown, all the means acting on the common trip-bar 16.
