Title: Improvements in and relating to the production of hydrated sodium metasilicate
IPC: C01B33/32
Filed: 1933-10-25
Abstract: Hydrated sodium metasilicate with 5--6 molecules of water of crystallization is obtained by cooling a hot concentrated solution of sodium metasilicate containing an excess of NaOH of from 20--35 grams per 100 c.c. of solution to a temperature between 60 and 25 DEG  C. The minimum permissible excess of NaOH increases as the crystallizing temperature decreases at the rate of about 2 grams per 100 c.c. for each 5 DEG  C.  A suitable initial solution contains 35--40 per cent by weight of sodium silicate calculated as Na2 SiO3.5H2O.  According to an example, the initial solution contains 40 per cent of sodium silicate and an excess of NaOH of 30 grams per 100 c.c.  It is cooled gradually with agitation to 40 DEG  C. to yield crystals corresponding substantially to the pentahydrate.  The crude crystals may be treated with sodium silicate solution containing an excess of SiO2 equivalent to the excess of HaOH in the adherent mother liquor, and if the correct amount of water is present the desired sodium silicate hydrate is formed giving a substantially dry product.  A solution containing about a 100 per cent molecular excess of SiO2 is preferred.  Specifications 921/08, [Class 1], 388,041, and 427,497 are referred to.

Title: Improvements relating to fluid pressure braking apparatus
IPC: B60T15/16
Filed: 1922-10-31
Abstract: 205,356. Winter, H. J., and Westing- house Brake & Saxby Signal Co., Ltd. Oct. 31, 1922. Fluid-pressure.-In a straight air brake wherein a valve automatically connects the operative driver's valve to the brake cylinder when the brakes are to be applied, a conductor's brake valve by which an independent application may be effected is provided, and is so constructed that the brakes so applied may be released by the driver from the opposite end of the vehicle by suitable manipulation of his valve, whether the conductor's valve be closed or open. In the form shown, a driver's valve 1 is provided at each end of the vehicle, and communication with the brake cylinder 3 is controlled by a double-check valve 5, which comprises a piston chamber 8 in which a piston 9 works, and valve chambers 10, 11, each containing a slide valve 12 operated by a stem 13 on the piston to control exhaust ports 14. When the right-hand driver's valve is operative and is moved to application position, the piston 9 is moved to the left, the brake cylinder is charged from the chamber 11 and the chamber 10 exhausts through its port 14. Similarly, when the lefthand valve is operative, the chamber 10 charges the brake cylinder, and the chamber 11 is vented. The conductor's brake valve 7, which comprises a cock 16 and a pressure-limiting valve 19 controlled by a spring 20, by-passes the driver's valve. When the cock 16 is opened, fluid passes from the reservoir 4 to the pipe 6 and the piston 9 is moved to the right, but the pressure with which the brakes are applied is lower than main reservoir pressure, because of the reducing action of the valve 7. To release the brakes at the opposite end of the vehicle the driver first moves his valve to application position, when fluid at main reservoir pressure entering the chamber 11 overcomes the lower pressure in the chamber 10 and moves the piston 9 to the left, thus venting the chamber 10. By moving his valve to release position the driver may now release the brakes, as the piston 9 will remain in its left position.

Abstract: 465,124. Photographic projection-printing apparatus. KODAK, Ltd. Oct. 31, 1935, No. 30050. Convention date, Nov. 2, 1934. [Class 98 (i)] Photographic projection - printing apparatus comprising a printing table having a printing panel therein and a platen movable to and from the panel is furnished with an elongated negative holder adapted to hold a strip of film and which can be set to extend in either of two directions at right angles to each other and parallel to the plane of the panel. As shown in Fig. 9, the platen 11 is carried on the upper arms 12 of four bell-crank levers, the lower arms 14 of which carry a registering screen 16 disposed over the printing panel 8. Pivoted to the platen 11 are four hooks 10. A sheet of printing paper P is laid over the screen 16 and positioned by the three fixed stops 71 and 73 and the stop 74 carried by the screen, and the platen is depressed and the exposure effected. The hooks 10 pass through the openings 9 in the plate 7 and engage the paper P, which is carried up on raising the platen and released on to the slide 24 by engagement of the rear hooks 10 with stops 22. The paper P passes from slide 24 to a shoot leading either to a receptacle or to developing apparatus. The platen is moved by a lever 81, Fig. 7, operating also through the link 79, and crank 77 and cam 97, a mercury switch 93 controlling the printing lamp. Depression of the platen depresses a knob 86 on a rod 87 rocking a.lever 90 to move the shutter 92 out of the path of the light beam. A button 100 enables the switch 93 and the shutter 92 to be operated for registering purposes independent of the movement of the platen. The negative holding carriage 27, Fig. 2, which is adapted for use with a short strip of negatives, comprises a fixed lower and a movable upper glass plate 29, held together by a latch 32, and is movable over the table 1 on rollers 33. The carriage 27 is positioned against a guide rail 36 held at one end by the engagement of an aperture therein with either of two pins 38, 39 carried by the table 1, and guided at the other end by either of two adjustable cams 40. In use, the negative holder is adjusted until the image reflected by the registering screen 16 and seen in an auxiliary mirror is registered with respect to the printing panel 8, the lamp being switched on by the button 100. A sheet of printing paper is taken from the container provided and placed on the panel 8, and the platen depressed and the light switched on by operation of the lever 81. A stamp 105, Fig. 7, passes through an opening in the platen and prints a number on the paper. After exposure, the lever 81 is released and returned by the spring 84, Fig. 7, the paper is lifted and sent down the shoot, the shutter 92 cuts off the light beam, and the light is switched off.

Filed: 1967-06-29
Abstract: 1,179,909. Fluid blast switches. WESTING- HOUSE ELECTRIC CORP. 29 June, 1967 [1 Sept., 1966], No. 30088/67. Heading H1N. In a fluid blast switch of the puffer type the movement of the flow producing piston 40 during heavy current interruption is assisted by attracting coils 41, 55 which carry the load current passing through an arc electrode 66 during the interruption. The piston 40 moves between concentric insulating cylinders 37, 38 and is coupled by rods 51, 52 to a moving contact 32 to which a connection is made through fingers 31a. The arcing electrode 66 is insulated from fixed contact segments 34 by a bushing 64 and connected by flexible lead 69 to one coil 41 mounted in the piston 40. The coil 41 is connected through one rod 51 and a flexible lead 61 to the other coil 55 mounted in the fixed end of cylinder 37; the coil 55 is finally connected by flexible lead 62 to the fixed contact structure. The initial opening movement of contact 32 and piston 40 is by a mechanical linkage (Fig. 1, not shown). The initial blast 49 transfers the arc 63 to the electrode 66 connecting the coils into the circuit to assist the action. The electrode 66 is well spaced from the moving contact 32 during closing preventing an arc striking between them so that attraction of the coils tending to prevent closure of the contacts is avoided. The switch is mounted in a sealed envelope filled with SF 6 .

Title: Method of loop doubling on a double needle bed rib end knitting machine and such a machine operable to carry out a loop doubling operation
IPC: D04B15/00
Filed: 1973-06-27
Abstract: 1399579 Knitting machines FABRIQUE NATIONALE HERSTAL SA 27 June 1973 [29 June 1972] 30550/73 Heading D1C In a double-bed flat knitting machine, after the knitting of a rib end on both beds some of the loops are transferred from the first bed 1 to the second bed 2, the beds are racked relative to one another and the remaining loops on the first bed 1 are transferred to needles in the second bed 2 which already carry loops thus producing doubling after which the groups of stitches are lifted on a transfer comb 7 so arranged that the gaps between the groups can be closed so that the stitches are all separated by one needle space only. The needles of bed 1 have long butts apart from those carrying the loops which are to be doubled which have short butts. The U- shaped section catch bar 5 of the needle raising device 3 for needle bed 1 has grooves 11 in its wall at positions corresponding to the positions of the short butt needles while the rib is being knitted so that operation of bar 5 during the first loop transfer does not affect the needles with short butts. When bed 1 has been racked one needle space, the short butt needles can be engaged by the wall of bar 5 away from the grooves so that these needles are then raised. When doubling is completed as shown the loops are arranged on groups of seven needles, one at one end of each group carrying two loops, separated by an empty needle. The transfer comb 7 has sets of seven points carried on blocks 12 slidable between members 14, 15 and connected together by hook members 21, 22 and engaging stop members 24 so that when jack 23 pulls the end member 21, 22 in the direction of the arrow F the blocks 12 move so that the end points 13 of adjacent groups are two needle spaces apart whereas movement of the jack in the opposite direction reduces this separation to one needle space. Needles in bed 2 are raised by catch bar 6 for transfer of the loops to comb 7.
