Title: Method and apparatus for surfacing glass
Inventor: DAVIS CURTIS WOODWARD
IPC: B24B7/26
Filed: 1957-06-24
Abstract: 841,955. Surfacing glass sheets. LIBBEYOWENS-FORD GLASS CO. June 24, 1957, No. 28289/59. Divided out of 841,954. Drawings to Specification. Class 60. Individual glass sheets are surfaced by means identical with those described in Specifications 841,954 and 841,956, but the claims are concerned with means (e.g. supports 61,Fig. 3 (not shown)), for supporting each of the individual sheets so as to lead each sheet into alignment with the space between the tools of each pair of surfacing tools, and the effecting of a positive spacing of the sheets as they pass between the tools to prevent the sheets working against the adjoining edges of adjacent sheets.

Title: Improvements in the manufacture of sequestering agents
Inventor: WOMERSLEY PETER
IPC: C11D3/33
Filed: 1953-10-15
Abstract: A sequestering agent comprises the tetra sodium salt of ethylene diamine tetra acetic acid enclosed in a network of silica gel.  To 40 parts sodium silicate diluted with 100 parts water there are added 33 parts of a slurry made up of 11 parts ethylene diamine tetra acetic acid and 22 parts water.  The addition is made as quickly as possible and with the maximum stirring possible without undue aeration.  The mass quickly sets to a solid and a considerable proportion of water separates within a short period by syneresis.  The product is then dried.  The proportions of reactants may be varied from the above to give a product having excess of acid or one having an excess of sodium (and thus of sodium silicate).

Title: Improvements relating to gear wheels
IPC: F16H55/14
Filed: 1929-09-19
Abstract: 319,289. Associated Electrical Industries, Ltd., (Assignees of Peterson, R. E.). Sept. 19, 1928, [Convention date]. Toothed wheels. - To prevent noise, particularly in railway vehicle drives, a gear wheel 3 has rings 16 of cast iron, lead, babbitt metal, or like non-sonorous material secured to the inner sides of its rim. The rings are fitted accurately and secured in place by welding metal 20 into recesses in the rim and ring. In a modification, the rings may be split and forced to gripping- position by wedges between their ends, that position being maintained by welding metal into the gaps. Alternatively, fibrous material is placed between the rim and ring, which are welded together at one or more points.

A fertilizer composition which is continuously released over a long period is produced by mixing components having various release times. The granules have a diameter of 0- 10 mm. The fertilizer is urea, calcium cyanamide, a nitrate or Thomas meal. The granulating agent is fatty alcohol polyglycol ether, alkyl phenol polyglycol ether, fatty acid alkylolamide, fatty acid alkylolamine ester; glycerine monostearate or monoricinoleate, trimethylolpropyl monocaprinate, pentaerithrite monocaprylate, anhydrosorbite monolaurate; pentaerithrite tristearate, glycerine di- and tri-stearate, octyl alcohol, ricinoleic acid, 12-oxy-stearic acid; cetyl palmitate, stearyl stearate, stearyl alcohol, stearic acid, paraffin wax, stearic acid amide, or distearyl ether.

Title: Improvements in means for controlling two-speed polyphase motors for lifts
IPC: B66B1/08
Filed: 1926-11-13
Abstract: 281,851. Smith, Major, & Stevens, Ltd., and Stevens, P. H. Nov. 13, 1926. Electric plant..-In a control system for a two speed pole-changing polyphase motor A<6> working a lift A, the control apparatus includes a highspeed switch F and a low-speed switch E mechanically interconnected so that one opens as the other closes, the two being operated in common by an electromagnet F<1> against a retracting weight F<2> or an equivalent spring. The apparatus also includes up and down directional switches G, H operated by electromagnets G', H', and a lift cage master switch J whereby the directional and speed-changing magnets are energized. The motor is geared to a counter-shaft B which through automatically engaged friction clutches C, D actuates interlock switches, L, L' and switches M<2> for varying resistance M. In the arrangement shown the resistance M is inoperative until the connections are changed from high-speed to low-speed, whereupon the clutch D is released and a weight D<4> turns a cam-shaft M<1> to cut-out the resistance. In a modification the resistances are arranged as accelerating resistances short-circuited during the high-speed stage.

Title: Improvements in or relating to methods of plating crystals
Inventor: DRAKE CYRIL FRANCIS
IPC: C23C18/44
Filed: 1953-10-16
Abstract: Conducting silver coatings are formed on non-metallic crystals by immersing the crystal first in a surface-activating bath and then in a solution of silver nitrate in pyridine to which has been added a small quantity of phenylhydrazine dissolved in pyridine. The activating bath may be of stannous chloride in ethyl alcohol. The crystal may be repeatedly immersed in the silvering solution with intermediate washing in ethyl alcohol to increase the coating thickness or, after the first layer has been deposited, the thickness may be built up by electrolysis, using a solution of silver and potassium cyanides in anhydrous ethyl alcohol with a silver or stainless steel anode.  Crystals of ethyl diamine tartrate and barium titanate are referred to.

Class 38(v) In a switch-fuse assembly, the switch and fuse are arranged one behind the other on opposite sides of a panel, so as to save panel space. As shown in Fig. 2, the fuse and switch are arranged directly behind one another, but in Fig. 1 (not shown) they only overlap to a'certain extent. Each assembly may be mounted on a separate panel, or groups of assemblies may be arranged on a common panel. Alternatively, the assemblies may be on horizontal or vertical strips which form a composite panel. In each case, the switch comprises a pivoted blade 15 having an arcing contact 15c and co-operating with fixed main resilient contacts 13a, 14a, and arcing contact 13b. The operating lever 19 is pivoted at 18 and has a forked part 17 engaging a rod 16 interconnecting two or more poles for simultaneous operation, the other end of the lever 19 extending to the front of fuses 12 through a slot in the base 11. In the form shown, a hinged cover 20, having a slot through which the lever passes, is provided, the lever and cover preferably being arranged so that the cover can be lowered only when the lever is in the "off" position 19a. In Fig. 1 (not shown), the lever has a lateral projection which prevents removal of a fuse when the switch is "on".

Abstract: 721,360. Removing waste thread from spools. REINERS, W. Dec. 12, 1951 [Jan 18, 1951], No. 29068/51. Addition to 721,359. Class 120 (3). The apparatus of the parent Specification is modified in that cutting means are arranged adjacent the suction nozzle 8 and a support 22 is arranged for supporting a spool 1 exteriorly of the nozzle so that the thread end 2 located within the nozzle is in a position to be cut by the cutting means which, as shown, are formed by scissor blades 20, 21. The spool end 3 is first inserted in the inner nozzle tube 6, the thread end being sucked between the inner and outer nozzle tubes 6, 7 ; an ejector 12 is then moved to the left by rotation of a cam 32 to eject the spool onto support 22 where it rests against a stop member 23, the thread end 2 remaining in the suction nozzle. Rotation of a second cam 38 causes blades 20, 21 to sever the thread end and lowers a stop 40 for member 23 which then pivots at 39 under the weight of the spool and allows the spool to slide down support 22 to a collection box. Member 23 is so weighted as to swing back to the position shown.
