Title: Process for the production of prints and prints produced thereby
IPC: G03F1/88
Filed: 1962-09-04
Abstract: 955,643. Pictures. D. G. DOUGHTY. March 22, 1963 [Sept. 4, 1962], No. 33893/62. Heading B6X. [Also in Division G2] A process for the production of a negative grid from which prints having enhanced or highlighted details in the form of iridescent effects can be produced, comprises the steps of photographical production of the negative grid by placing over an original picture a transparent carrier material provided with parallel, closely spaced lines, e.g. 200 lines per inch, masking all but a selected portion of the original and photographing the selected portion of the original with the lines superimposed thereon. The operation is repeated by changing the orientation of the original or carrier, marking all but the selected portions of the original and rephotographing to produce a plurality of lined images which are combined to form the said negative grid. Subsequently conventional printers' blocks or plates of identical size are made from known metals used, e.g. zinc or copper, for both negative grid and the original picture whereupon the picture is printed by letterpress, lithography or gravure in ink, which may be transparent, on thin metallic foil having a waxed paper backing, thus providing a mouldable, resilient surface. The finished print of the original is then letterpress printed " blind " by superimposing the negative grid block in exact register with the original to produce on the latter minute, closely spaced ridges extending in different directions in accordance with the images to conform with the selected portions, which are to be highlighted or enhanced by means of light reflected from different parts of the finished print in the form of iridescent effects. In another embodiment a second adhesive transparent carrier having openly spaced lines, e.g. 50 or 60 lines per inch, is superimposed on the first transparent carrier, with the adhesive side facing the latter. The negative grid is then produced by initially cutting around a selected portion of the adhesive carrier and thereafter successively changing the orientation of the adhesive carrier and cutting around other selected portions to produce a negative grid adhering to the first transparent carrier. The following step comprises reduction photographically of both the original picture and the negative grid to about “ or<SP> </SP>1/3 of the original size thus increasing the density of the lines on the negative grid to about 200 lines per inch, thus rendering them imperceptible to the eye. Subsequent steps of production of the finished print are identical with those of the first embodiment.

Title: Improvements in and relating to polysiloxane resins
IPC: C08G77/06
Filed: 1946-11-15
Abstract: A polysiloxane resin is prepared by partially hydrolysing a mixture of chlorsilanes, including a major proportion of methyl chlorsilanes and having a hydrocarbon to silicon ratio between 1 and 2, by addition of less water than is required for complete hydrolysis, heating the partially hydrolysed product to remove dissolved HCl and then adding sufficient water to complete conversion of chlorosilanes to polysiloxanes.  Hydrolysis may be performed in a medium of an ether, e.g. diethyl ether, dioxane, or diethyl "Cellosolve" (Registered Trade Mark) or diethyl carbitol.  The invention is particularly concerned with methyl and methyl phenyl polysiloxanes prepared from mixtures containing major proportions of methyl trichlorosilane, phenyltrichlorosilane or mixtures thereof.  In example (1) water was added drop-wise with agitation to a mixture of methyltrichlorosilane and dimethyldichlorosilane in dioxane and mineral spirits.  The product was refluxed to remove HCl, cooled and more water added.  Refluxing was then restarted.  Dioxane was then removed and a resin solution recovered.  It may be neutralized and filtered.  In example (2), a mixture of methyltrichlorosilane, dimethyldichlorosilane and diphenyldichlorosilane in diethylcarbitol was used.  The product was freed from solvent and dissolved in toluene.  In example (3), a mixture of methyltrichlorosilane, dimethyldichlorosilane and silicon tetrachloride in diethyl cellosolve was employed. Specifications 542,655, 585,627 and 590,736 are referred to.

Title: Improvements in or relating to electric chiming and/or striking clocks
IPC: G04C21/10
Filed: 1937-12-15
Abstract: 507,489. Electric clocks. STUART, J. F. W., and NORTON, F. D. Dec. 15, 1937, Nos. 34677/37 and 2351 /38. [Class 139] Striking-mechanism ; chiming-mechanism.- The motor of an electric synchronous motor clock imparts regular motion to one element of a separable clutch, the other element of which is connected to a chime or striking drum, one of the elements or an associated part functioning as a counter to govern the number of chimes or strikes in combination with a locking member actuated by or from the time indicating mechanism and also maintaining the clutch elements in operation until the locking member enters a notch or depression. The hands 2, 3, Fig. 2, of the clock are driven from a synchronous motor 1 through suitable reduction gears which also drive a pinion 6 and clutch member 7. Before each quarter a tappet wheel 22, Fig. 1, on the minute hand spindle rocks a lever 20 and depresses a bell-crank 17, Fig. 2, a projection 15 being then withdrawn from a recess 14 in the chiming drum 9, and allowing a slight rotation of the latter due to frictional engagement of the member 7 and spring 8, but limited by a peg 27 engaging a stop 28. When the bell-crank 17 is released, the chiming drum 9 is pushed laterally to engage clutch members 7, 12 whereupon the drum rotates to effect the chimes until the projection 15 enters the next recess 14. A snail 47, Fig. 1, on the chiming drum initiates striking. A lever 45 is rocked and depresses an arm 40b of a bell-crank 40, Fig. 3, and a peg 42 is withdrawn from a slot in a counting disc 33. Moreover, a projection 57 depresses an arm 56 to rotate slightly a shaft 55 carrying the striking hammer 54, and this allows a slight rotation of the pinwheel 51 and. a slight movement of the disc 33 out of register with the peg 42. Upon release of the bell-crank 50 the disc 33 is pushed laterally to engage the clutch members 34, 38 and effect striking. The chiming mechanism is self-correcting and the striking mechanism -may be also. The invention may be adapted to a striking- clock without chiming mechanism.

Abstract: 906,476. Turbine and compressor blades. FAIRWEATHER, H. G. C. (Westinghouse Electric Corporation). Oct. 11, 1960, No. 34843/60. Class 110 (3). A turbine or compressor rotor comprises blades 11, a blade supporting member 10, having recesses 16 and arcuate grooves 23 in endwise communication therewith, blade-retaining means 14 having a groove 20, the grooves 20, 23 being open-ended and facing each other, and a spring member or clip 25 received in the grooves and locking the retaining means against axial movement, the spring member 25 being deflectable radially to permit insertion and removal from the grooves and having means co-operating with the retaining means 14 to lock the spring member 25 against longitudinal displacement in the grooves 20, 23. The ends 26 of the spring member 25 are the same width as the groove 23 and the width of the central portion 27 is reduced to that of the groove 20. Shoulders 28 on the spring members abut side faces 18 on the blade roots to provide locking means against longitudinal displacement. In one method of assembly the spring member 25 is placed in the groove 23 before the blade is inserted (Fig. 1), When the root portion contacts the member 25, the central portion 27 is deflected radially inwardly and when the grooves 20, 23 are in alignment, the clip is released. The blade may be removed by applying a suitable tool to either or both ends of the clip, thereby deflecting it clear of the groove 20. By varying the width of the clip if desired, a limited degree of axial movement of the blade is possible. Since the ends 26 of the clip are visible after assembly, inspection of the blade locking components is facilitated.
