Title: Improvements in altimeters for use in aircraft
IPC: G01L19/08
Filed: 1935-04-06
Abstract: 454,931. Altimeters. WRIGHT, G. M., Broom Hall, Woodham Ferris, Essex. April 6, 1935, No. 10687. [Class 106 (ii)] A boss 3 on the evacuated capsule 1 is provided with a contact 4 working between contacts 5, 6 on the frame 2 the contacts 4, 6 being connected in circuit with a battery 13 and the primary of a transformer 12. The secondary of the transformer is in circuit with a neon lamp 14 adapted to illuminate a scale 11 over which moves a pointer 10. Attached to the spindle 8 of the pointer is a flat spring 7 the other end of which is pivoted to the boss 3. The spindle 8 is rocked constantly so that the pointer oscillates between the highest reading on the scale and zero the contact 4 just touching the contact 5 and 6 in these positions. During every oscillation, the force exerted by the spring 7 will just balance the force exerted by the atmospheric pressure at some point during its movement and immediately after this balance, the contact 4 will flip suddenly from the contact which it is engaging to the other contact there to remain until balance is achieved in the next oscillation when it will flip back. This flip causes a sudden momentary current to pass through the primary of the transformer and therefore a momentary current will be induced in the secondary causing the Neon lamp to strike and illuminate the needle.

Abstract: 107,029. Naletoff, M. May 10, 1916. Discharging and feeding devices for endless chain and rope conveyers; driving-gear; screw and worm conveyers.-In a conveyer system, the speed and distance apart of the articles carried are varied without shook at certain points of the system by dividing the system into several sections so arranged that before any article is disengaged from any section, it will be engaged by the next section, and connecting the driving-gear of adjacent sections by non-circular wheels so arranged that when an article is passing from one section to another, the speed of the latter section will be the the same as that of the former. In the arrangement shown in Figs. 5 and 6, the articles P<1>, P<2> are connected by teeth to screw conveyers B<3>, B<4> which are connected by a worm wheel F, non- circular wheels C, C', bevel-gearings D, D<1>, and gears D<2>, D<3>. The screw B<4> is rotated at a periodically changing speed, but is moving at the same speed as the screw B<3> when an article is being transferred to it. Instead of two screw conveyers, two endless rope or chain conveyers may be connected by similar mechanism, or a screw conveyer may deliver to an endless-chain conveyer. The non-circular wheels may be of spiral form instead of the shape shown, and more than two such wheels may be employed.

Title: Rubber and plastic formulations and process
IPC: C08K9/12
Filed: 1960-03-28
Abstract: Curable natural or synthetic resins, e.g. comprising natural, nitrile, or neoprene rubber, polyurethanes, polyvinyl chloride, incorporate a small amount, e.g. 1-3 parts per 100 parts by weight of resin, of an activated crystalline zeolitic molecular sieve material for absorbing undesirable and detrimental contaminants, e.g. hydrogen sulphide, hydrochloric acid, moisture, in the resin which cause pitting and discolouration in the final product.  The activated zeolitic material is produced by heating a natural or synthetic zeolite to remove water of hydration, preferably under reduced pressure, until the water content is less than 5% by weight. Suitable synthetic zeolites include sodium, potassium, or calcium zeolite A, zeolite B, and zeolite T, whilst natural zeolites include erionite, chabazite, mordenite, and clino-ptilolite.  The activated zeolitic molecular sieve material may be incorporated in curable resin compositions comprising a crystalline zeolitic molecular sieve loaded with a curing accelerator, e.g. piperidine, pyrocatechol, or a peroxide catalyst, e.g. ditertiarybutyl peroxide, for the purpose of absorbing impurities, e.g. moisture, in the resin, which would otherwise displace the adsorbed accelerator, &c., with disadvantageous results, e.g. premature vulcanization or scorching.

Patent GB-181303-A (GB)
Title: Improvements in and relating to automatic weighing machines
IPC: G01G21/00
Filed: 1921-01-24
Abstract: 181,303. Boulogne, B. Jan. 24, 1921. Automatic-feed weighers.-In an automatic weighing-machine for liquids or granular materials, of the kind in which after each discharge from the weighing-receptacle a residue is left behind, the weigh-beam consists of a bent lever provided with a counterbalance weight for restoring the receptacle to filling position with the requisite residue therein. In the Figure is shown a machine for weighing liquids, the weighing receptacle 1 being arranged to rotate in a counterclockwise direction for the purpose of discharging its contents. In the operation of the machine, the liquid from the supply chamber passes through valves 20, 30 and enters the weighing receptacle 1. The rise of the liquid in the receptacle causes the receptacle to rotate in a clockwise direction until arrested bv contact of a stop 72 against a suspension rod 3. Further filling of the receptacle rocks an intermediate lever 4, 5 through which the receptacle is siispended from the bent weigh-beam 8, 9. The curved end 54 of the intermediate lever is withdrawn from beneath a lever 52 which falls on to a stop 56, whilst the arm 5 of the intermediate lever pushes back and liberates a rod 24 connected by a bell-crank lever 23 to the main valve 20 and to a lever 47 on the lever 52. The main valve 20 then closes under its own weight. When the weight of liquid is completed through the small valve 30, the bent weigh-beam 8, 9 rotates and an arm 57 integral with the beam knocks up and liberates a rod 39 connected to a pivoted catch pan 38 which falls to a position beneath the feed valves. The movement of the catch pan allows a counterweighted lever 33 to fall and push up the valve 30 to stop the feed. Owing to the rotation of the weighbeam 8, 9, a pin 15 on the receptacle 1 engages a fixed guide 16 and causes the receptacle to rotate into the lower position shown in dotted lines and allow the liquid to run out at the nozzles 11, 12, until the receptacle is returned by the counterweight 10. The return movement resets the parts in the position shown in Fig. 1. The arm 57 is connected by a pin 60, loop 62, and lever 63, to a dash-pot 69 for absorbing shock. The pin-and-loop connection 60, 62 leaves the weigh-beam free of the shock-absorbing device in its extreme positions. In a modification, the shock-absorber is coupled direct to the weighbeam arm 9.

Title: Improvements in or relating to centrifugal borehole pumps and apparatus, using thrust bearings
IPC: F04D29/04
Filed: 1925-05-04
Abstract: 254,832. Stocks, C. H. May 4, 1925. Arrangement of bearings; casings.-Centrifugal pumps for boreholes are supported by an ordinary thrust bearing and have, in addition, extra ball or roller thrust bearings acting on the shaft under the reactive force of a non-rotary spring to assist in supporting the weight. These bearings are enclosed in a two-part casing supported on the usual surface water-exclusion pipe a by a tubular flange b<3> on the lower half of the casing which also has fins b<4> to steady and centralize it. The upper part b<1> of the casing is bolted to the lower part when all the mechanism is in position, and the driving motor d is mounted on the top of the casing, its shaft being connected by a flexible coupling f to the shaft e which is in turn coupled to the pump shaft i. An internal extension b<5> of the tubular flange b<3> supports a boss k<1> which carries the pump riser pipe j and the delivery nozzles l<1>, l<2>. A spider m is also carried by the boss k<1> and it supports a bearing with an indiarubber bush off the type described in Specification 159,473, the inner face of the bush being spirally grooved to permit grit to escape. The annular passage o through the bearing is of double-cone or hour glass section so that grit in the rising stream is directed into the more rapid part of the stream and projected beyond the bearing. The upper part of the casing supports a container b<6> for the usual radial and thrust bearings. Beneath this container is a conical enlargement e<1> or flange on the shaft; this fits into a collar e<2> which forms the upper part of a ball bearing e<5>. The lower race of this bearing engages a coned ring e<6> carried by the inturned flange of a sleeve e' which is supported by a heavy helical spring e<8> in a box b<7> bolted to the container b<6>. The spring thus helps to support the pump. Extra spring-supported bearings may be added if desired. Lubricating oil is led to the top of the container b<6> by a pipe, q from a tank q<2>. The oil passes through the bearings and is led by the pipe q' to the tank q<4>. It can be returned to the tank q<2> by means of the hand pump q<5>.
