Title: Improvements relating to window operating mechanism
IPC: E05F11/38
Filed: 1938-02-10
Abstract: 507,352. Window regulators. WILMOT - BREEDEN, Ltd., and SMYE, A. Feb. 10, 1938, No. 4171. [Class 20 (iii)] Operating mechanism for a sliding window comprises a pair of flexible cables which are wound around a rotatable drum or drums mounted on or adjacent the window frame and which have their ends connected to different and widely separated parts of the window. The cables are fitted with means to give them the requisite tension, and handoperable means are provided for actuating the drum or drums. In the construction shown, two cords i are passed around drums h mounted on opposite ends of a shaft e and have their ends connected to brackets j secured to the upper and lower edges of the sash c. Each upper bracket slidably receives a short stem k to which the cord is secured, and the adjustment of the stem is affected by a nut m which thereby controls the tension in the cord. The drums h are loosely mounted on the shaft e and have extensions which form parts of slipping clutches adapted to prevent damage to the mechanism caused, for instance, by over-winding the operating handle b. In a modification, a single drum is provided and is arranged adjacent the operating handle. Each of the two cords passes around the drum and over a pair of guide pulleys and has its ends connected to diagonally opposite corners of the sash frame.

Title: Improvements in the manufacture of acetic anhydride
IPC: C07C51/235
Filed: 1938-02-10
Abstract: 510,959. Acetic anhydride. DREYFUS, H. Feb. 10, 1938, No. 4202. [Class 2 (iii)] Acetic anhydride is prepared by oxidising acetaldehyde by means of free oxygen in the presence of liquid aliphatic hydrocarbons in amount sufficient to dissolve all the anhydride formed and hold it in a substantially non- aqueous phase, removing the water while maintaining the anhydride in its non-aqueous phase, and separating the anhydride from the hydrocarbons, thereby reducing the loss by hydrolysis of the anhydride. As hydrocarbons there may be employed petroleum fractions, e.g. benzine and fractions boiling, e.g. up to 150-200‹C., and individual hydrocarbons, e.g. the pehtanes and hexanes. The oxidizing gas may be oxygen, air or oxygen diluted with, e.g. 5 to 30 times its own volume of an inert diluent gas, e.g. nitrogen, carbon dioxide, methane. An oxidising catalyst, e.g. copper, cobalt, nickel, manganese as acetates, 'oleates, stearates of linoleates, may be used. Pressure is preferably superatmospheric, e.g. 25-65 lb. sq. in., and the'temperature range is generally between 35-75‹C. Reaction may be made continuous by separating the aqueous andhydrocarbon layers, distilling off the hydrocarbon and returning it to the reaction zone together with fresh acetaldehyde. The oxidising gas may be led into the hydrocarbon, acetaldehyde mixture, or acetaldehyde vapour and oxidising gas is led into the hydrocarbons, the gases or vapours preferably being forced through fine jets or a series of narrow reaction tubes. Some of the hydrocarbon may be distilled off during oxidation, when part or all of the water is entrained. In examples (1) air is forced into a mixture of acetaldehyde and benzine containing .2 per cent. copper oleate heated in an autoclave under 60 lb. sq. in. pressure, to about 65‹C.; the hydrocarbon layer is separated from the aqueous layer which contains acetic acid, and acetic anhydride is recovered by distillation ; (ii) air is forced into a mixture of acetaldehyde and a petroleum fraction boiling about 80-110‹C. containing copper oleate in a number of narrow tubes heated to 60-65‹C. and under 65 lb. sq. in. pressure ; (iii) air and acetaldehyde vapour is fed into benzine containing copper oleate in a set of narrow tubes as in (ii).

Title: Improvements in and relating to snap-action devices particularly adapted for electric switches
IPC: H01H13/36
Filed: 1944-03-09
Abstract: 575,233. Snap-action switches. BRITISH THOMSON-HOUSTON CO., Ltd. March 9, 1944, No. 4403. Convention date, March 12, 1943. [Class 38 (v)] In a snap-action switch constructed as set out in Specification 564,681, the relative dispositions of the pivotal points of the compressed members and the contacts or stops are arranged so that the ends of the stressed member move separately and in sequence with a snap. In Fig. 2 the bottom pair of fixed contacts 21, 21 are of different sizes, as also are the top pair 20, 20, so that the tension members 11 of the member carrying the moving contacts 18, 19 when at rest are not perpendicular to the line of movement of the actuating member 30, 31, 32. When that member is depressed against a spring 35, the point of engagement of compression member 16 with the spring 32 on the actuating member first passes the plane in which the tension members 11 lie so that the left hand contact 18 snaps upwards, and this movement or further downward movement of the actuating member causes the end of the other compression member 17 to pass the dead centre point and contact 19 snaps upward. When pressure is removed from the knob 31 it rises under the force of the spring 35 and the contacts 19, 18 snap downwards in sequence. A switch is described in which the sequential movement of the contacts is obtained by a difference in the lengths of the springs 32, 32 of the actuating member, Fig. 3 (not shown). A switch is also described in which only the top pair of contacts aie of unequal size so that contacts 18, 19 move upwards simultaneously and downwards in sequence. Also a diagram is shown of connections in which the switch is used for reversing a motor which has a forward and reverse field windings.

Abstract: 138,446. Barnes, F. W. Feb. 25, 1919. Saddles.-In cycle saddles having the top pivoted at the rear to laminated springs secured at the other extremity to the cycle frame or a fitting thereon, the front end of the top is supported by a roller connected to the top and arranged to engage with a downwardly and rearwardly inclined guide carried by the cycle frame or a fitting thereon. As shown in Fig. 1, the laminated springs e, pivoted at d to the top c, are clamped to a cross-tube h on the frame, and the roller s is mounted at the front end of a laminated spring q clamped at its rear end to a bracket k which is angularly adjustable with respect to a bracket j upon the saddle top. The roller engages with a channel-section guide t, and the walls of this guide have upper overhanging edges, which, near the front, are cut away to clear the ends of the pin r carrying the roller, the arrangement being such that, when the saddle is not loaded, the pin and roller can be disengaged from the guide and the top turned back about the pivot d; this provides means for preventing the seating surface from getting wet when the machine is left out in the rain. Instead of forming part of the frame, the tube h may be clamped or brazed to it. In a modification, the springs e are clamped to laterally-extending parts of a cranked plate brazed to the top of a vertical saddle pin which also carries the guide t; in this case, the spring q, instead of being coiled about a pin r, may be riveted to a plate formed with ears between which the roller is mounted, the projecting heads (,f screws serving to retain the roller in the guide. According to the Provisional Specification, the roller, of solid rubber, is carried between depending lugs upon the top and may roll upon the inclined rear end of the top tube of the frame.

Class 120(2) In a weighting device, for the simultaneous loading of the top rollers of a drawing head of a textile machine by means of fluid pressure, a box-like arm is pivotally mounted at the rear of the drawing head and extends from the rear to the front thereof and the upper part of the arm is formed into a pressure chamber by means of a diaphragm with which, members for transmitting pressure to the top rollers of the drawing head are in contact, whereby the pressure in the chamber is transmitted from the chamber to the top rollers. As shown the device comprises an arm 14 having a cover 10 which holds in position a diaphragm 18 so as to form a pressure tight chamber 20. An aperture 12 is formed in the cover 10 connecting it to some pressure source. The arm 14 carries sliding blocks 24 located above the top rollers K, K\ K<SP>2</SP>, &c. and the blocks are secured in their adjusted position by screws 26. Each block 24 is formed with a passage to receive a slidable member 30 against the head 32 of which the under surface of the diaphragm 18 bears. The lower end of each member 30 bears on its corresponding roller. Each arm 14 is locked in its operative position by a catch 46. As shown in Fig. 1, a weighting device B', B<SP>2</SP>, B<SP>3</SP>, &c. is arranged over each drawing head, each pair of weighting arms being connected by a rigid tube 38 and adjacent pairs being connected by flexible pipes 16 such that fluid under pressure is transmitted through the whole system. This arrangement also permits each pair of arms to be raised from their operative position independently of its neighbours. In a second embodiment the diaphragm acts on slidable levers, one arm of each lever being in contact with the diaphragm and the other being provided with a clip for engaging a neck on the corresponding roller. Also in this arrangement the fluid pressure is transmitted through a single tube. each arm being arranged to pivot about the tube and means being provided to put the fluid chamber in the arm in communication with the tube only when the arm is in its operative position.
