Title: Improvements connected with relieving mechanism for use with analytical balances
IPC: G01G1/00
Filed: 1951-05-17
Abstract: 720,271. Weighing apparatus. OERTLING, Ltd., L., and HODSMAN, G. F. May 16, 1952, [May 17, 1951; Feb. 16, 1952], Nos. 11510/51 and 4155/52. Class 143. In an analytical or chemical balance provided with an arrestment frame for relieving the balance and scale pan knife edges means are provided for automatically reducing the velocity of impact of the knife edges on their bearing surfaces when the weighbeam is returned, under gravity, to its operative position. As shown, a knob operated outside the balance casing rotates a shaft p, cam o and lever f pivoted about an axle g, which lever raises a rod e operating to raise the relieving frame and lift first the scale pan supports, then the weighbeam off their respective knife edges. The axle g is connected through a cranked lever h and linkage n, m to a dashpot j with carbon cylinder and piston (for self-lubrication) so that on the relieving frame being released by rotating the shaft p the mechanism and knife edge bearings return slowly to the operative position. The link n comprises a block adjustably mounted in a recess in the lever h by means of a rod n<SP>1</SP> screwed in the block engaging in a tapped bush q having a screw head for permitting adjustment locked by a leaf spring r. This adjusts the setting of the dashpot piston relative to a second air vent near the closed end of the cylinder so that an ultimate increased speed of descent is permitted after a slow commencement to prevent the arms of the released weighbeam, after its knife-edge has been deposited on its plane, having sufficient time to swing and lift the scale pan supporting stirrups off the relieving frame. Link m consists of a flexible strip. The foot of the rod e is also adjustable. An aperture in the piston with flap valve permits of a quick return stroke of the piston when relieving the weighbeam. The dashpot main inlet vent may also have an adjustable flap valve.

Title: Improvements in fuel valves for internal combustion engines
IPC: F02M61/10
Filed: 1922-04-25
Abstract: 192,971. Day, C., April 25, 1922. Leakage, preventing; spindles. -Leakage of injecticn air from a fuel-spraying device for an internal-combustion engine is prevented by forming the valve stem in two parts, the upper part A<2> having a valve portion E which prevents leakage in the intervals between successive injections when the valve is seated. The joint between the upper portion and the lower part A<1>, is such as to allow a slight degree of relative movement of the two parts both laterally. According to a modified construction, the injection valve may open towards the combustion chamber in which case the outer member acts as a tappet to open the injection valve, the two portions being entirely disconnected from each other.

Filed: 1941-09-19
Abstract: 549,746. Supply meters. BRITISH THOMSONHOUSTON CO., Ltd. Sept. 19, 1941, No. 12044. Convention date, Sept. 21, 1940. [Class 37] Side thrust on the bearings is reduced by arranging the driving and braking magnets in the same plane or in parallel planes on the same side of the spindle. The driving and braking magnets may be incorporated in a single structure as shown in Fig. 6. The E-shaped voltage core 26 and U-shaped current core 28 are held in fixed relation between a pair of non-magnetic side plates, between which are also clamped the lower ends of two small permanent braking magnets 34, 35. The magnetic circuits of the braking magnets are completed by U-shaped laminations 37, 38 which may be, as shown, integral with the voltage magnet laminations. Between the current magnet and the brake magnets are gaps 50, in which are placed non-magnetic clamping bolts or rivets. The permanent magnets 34, 35 are preferably arranged with their upper ends of the same polarity and are surrounded by copper bands 51 to prevent demagnetization. The brake magnets are of high coercive force material, for example, as described in Specifications 179,306, [Class 82 (i)], 423,897, 423,994 and 424,746, [all in Group II]. The current winding 27 consists of a single turn. The rotor may be magnetically suspended by the repulsion between a disc-shaped magnet fixed to the lower bearing and a similar magnet carried by the lower end of the shaft. The braking torque is adjustable by screws 52 of magnetic material forming magnetic shunts. Alternatively the brake magnets may have axial threaded holes into which soft iron screws are fitted. Two similar complete driving and braking units may be arranged on opposite sides of the spindle for measuring polyphase energy. The armature disc may be built up of overlapping insulated sectors. In a modification, Fig. 11, the driving and braking fluxes cut the meter disc between the same pole pieces, the permanent magnets 71, 72 magnetically connecting the voltage core 65 and the current core 68. In another construction the driving and braking magnets are arranged along the same radial line of the armature and on the same side of the shaft but at different distances therefrom. The brake magnets consist of two horseshoe magnets on opposite sides of the disc with their poles facing one another, the magnets being arranged outside the driving magnet. Specifications 247,248, [Class 37], 462,443 and 516,128 are referred to.

In an hydraulic vehicle brake installation in which a pressure limiter is provided in the feed circuit for the rear wheel brakes, a by-pass is arranged in parallel with the limiter and includes an inertia member such that the by-pass is automatically opened for rearward travel and closes for forward travel as soon as the deceleration exceeds a minimum value. As described, the pressure limiter L, Figs. 1, 2 (former not shown), which may be controlled by the vehicle load, and by-pass D are arranged between conduits a<SP>2</SP>, a<SP>3</SP> connecting conduit (a) from the master cylinder (M) to the rear wheel brakes F<SP>2</SP>. The front wheel brakes (F<SP>1</SP>) are connected directly to the master cylinder via conduits (a<SP>1</SP>), (a). The by-pass comprises an inertia valve including a cylindrical body 3 connected via conduits 1, 2 to conduits a<SP>2</SP>, a<SP>3</SP> respectively and provided with a valve seat 6 closable by ball 8. The body is inclined rearwardly at an angle of about 5 degrees to the horizontal so that for all rearward motion the ball remains at the lower end of the body so that the limiter L is bypassed. For forward motion as soon as the deceleration exceeds a preset minimum, e.g. 4 m/s/s, the ball rolls up the surface of the body 3 to close the valve so that the braking pressure is controlled by the limiter. The limiter comprises two chambers 10, 11, connected respectively to conduits a<SP>2</SP>, a<SP>3</SP>, and in communication via aperture 12 closable by valve element 13. The element 13 is connected to a piston 14 which bears against a pivoted lever 15 connected via a spring 17 to the pivotal lever b of the rear wheel assembly. The valve element 13 will close the aperture 12, to isolate the rear wheel brakes from the rest of the braking system, when the pressure in conduit a<SP>2</SP> exceeds the thrust of the spring 17 which depends on the vehicle loading.

Abstract: 329,785. Western Electric Co., Ltd., (Electrical Research Products, Inc.). April 18, 1929. Preparing synchronous picture and sound records; sound-recording in association with kinematographs; records, preparing and duplicating. -In the production of a picture film and a sound record in synchronism, all the pictures of the film representing one location or scene, together with the corresponding sound records, are made to follow one another consecutively regardless of the order necessary in the finished film, and the picture film and sound record so produced are cut up and assembled in the required order, and a copy of the sound record made on a record of impressionable material, such as a record disc or cylinder, from which reproduction is effected in synchronism with the finished picture film. The original sound in any desired order may be recorded on a phonographic record which is copied on to a film to permit of editing into desired order as described. Fig. 1, with the switch 2 connected to the microphone 1, shows the arrangement for recording the sound on the picture film 9, or on a separate film, simultaneously with the taking of the pictures. After all the pictures representing that location have been made, the apparatus is transferred to another location to be represented on the film for continuation of its production. When completed; the film or the separate films are cut up and edited into correct order, and the sound record film is traversed between a light source and a photo-electric cell, the output from which operates an electromagnetic recorder to cut a record in a disc to be used for the reproduction of the sound in synchronism with the edited picture film. In a modified method, the original sounds may be recorded simultaneously with the making of the original picture film by means of a microphone and electromagnetic recorder on a. wax disc to produce a record 33, Fig. 6, in which the sections a, a', a<11> --- correspond with the sections of the picture film. This record 33 is then copied as an optical record on the side of the picture film in the apparatus shown in Fig. 1, and the combined record is then edited and a disc record made from the edited sound record in the manner already described. Reference has been directed by the Comptroller to Specification 340,566, [Group XXXVIII].
