Title: Improvements in or relating to synthetic resin products
IPC: C08G8/28
Filed: 1935-09-30
Abstract: A synthetic resin is prepared by heating together a natural resin (e.g. colophony, gum rosin, or run Congo), cresylic acid having a m-cresol content of not less than 50 per cent, and an anhydrous polymer of formaldehyde (e.g. paraformaldehyde or trioyxmethylene), until condensation of the three ingredients has taken place, and subsequently, preferably after a vacuum distillation, heating the product with a polyhydric alcohol (e.g. glycerol or polyethylene glycol) in the presence of a small quantity of a compound of an alkaline earth metal soluble in the reaction mix (e.g. lime, calcium acetate or magnesium borate) as catalyst.  The final product may be vacuum distilled.  It is preferable that condensation be carried out under a reflux condenser so adjusted so that the most volatile constituent may escape; that the conditions of time and temperature be so adjusted during the final step that the product has an acid number of about 15; that the m-cresol content of the cresylic acid used be between 50 and 60 per cent; and that the formaldehyde polymer be employed in slightly more than two molecular proportions relative to cresol.  In examples, (I) pale green rosin, cresylic acid (m-cresol, 60 per cent) and paraformaldehyde are condensed under reflux, and then vacuum distilled, the residue being condensed with glycerol in the presence of lime and then vacuum distilled; (II) WW rosin, cresylic acid (m-cresol, 50 per cent) and paraformaldehyde are treated as in example I.  It is stated that the mixed distillates obtained in example I may be used as a disinfectant.  British Specification 259,030, [Class 2 (iii)], and French Specification 592,584 are referred to.ALSO:In a process for preparing synthetic resin by heating pale gum rosin, cresylic acid, and paraformaldehyde under reflux, vacuum distilling, adding glycerine and lime, and again vacuum distilling, the mixed distillates, containing rosin acids, cresylic acid, formaldehyde, glycerol, and water, are stated to be of use as a disinfectant.

Title: Improvements in and relating to light ray projectors and reflectors
IPC: F21V5/00
Filed: 1924-07-30
Abstract: 246,192. Halsbury (H. Goulburn), Earl of. July 30, 1924. Testing-apparatus, auxiliary.-In a vehicle headlamp or other light ray projector, the amounts by which the elementary beams issuing from a series of horizontal elements of the lamp front must be deflected in order to make their axes substantially horizontal and to bring them substantially within the main horizontal beam from the lamp are determined by placing in front of the lamp a diaphragm having a narrow horizontal slit and by measuring, for different positions of the slit, the amounts by which the rays of light projected through the slit deviate from the horizontal. In one form, a diaphragm 3, Fig. 5, having a slit 4 is placed in front of a lamp 1 and the distance 8 on a screen 5 and the distance between the diaphragm and the screen are measured so as to determine the angle of deviation # between the projected ray 6 and the horizontal line 7. The refracting angle a which should be given to each of the horizontal prisms d', d<2>, &c., Fig. 1, in order to bring the ray 6 into coincidence with the horizontal line 7 is then calculated from the formula Á=sin(alpha+#)/sin a where Á is the refrective index of the glass &c. from which the prisms are made. The series of prisms d<1>, d<2>, &c. may be replaced by a single composite prism with either a curved front or rear face, the other face being plane, or with both faces curved. In another form, a downwardly directed lamp 9, Fig. 6, has a plane mirror 11 hinged at 12 so that by measuring, for different positions of a slit 14 in a diaphragm 13, the angle of inclination of the mirror 11 necessary to bring the rays of light projected through the slit on to a screen 16 into a horizontal direction, the angles of inclination of the different portions of a curved mirror f, Fig. 3, can be determined. The mirror f instead of being curved may comprise a series of three or more plane surfaces. A certain amount of diffused light for general illumination is provided by rays of light which diverge upwardly from the horizontal axes R of the elementary beams, and, in order to illuminate the roadway a short distance ahead of the lamp, some of the lower prisms d<1>, d<2>, &c. or the lower portion of the mirror f may be arranged to give a somewhat greater downward deflection to a portion of the elementary beams, as shown at R<n> in Figs. 1 and 3.

Title: Improvements in or relating to pistols to be used for slaughtering purposes said improvements being also applicable to other weapons
IPC: A22B3/02
Filed: 1929-09-07
Abstract: 339,671. Accles, J. G. Sept. 7, 1929. Addition to 322,439. Breech actions, movable barrel other than dropdown; firing-appliances.-Relates to the pistol for slaughtering or other purposes described in the parent Specification, which pistol is adapted to be opened by turning the barrel g about a vertical pivot x, and is fitted with a special form of slip-lock trigger mechanism comprising a rearwardly extending sear b, released from the bent i by striking a fixed pin d. According to the present invention, the firing pin e is retracted, prior to opening the weapon, by withdrawing a barrel-locking pin f, and the sear does not engage the bent until the firing pin is so withdrawn. The firing pin cannot therefore be repeatedly snapped by operating the trigger a. If the trigger is accidentally operated when the weapon is open, the firing pin is cocked by the bolt f riding up an incline on the face of the barrel during the closing movement. The barrel is locked at the instant of firing by the engagement of the trigger a in a recess p in the barrel. Specification 139,284 is referred to.

Abstract: 880,829. Controlling aircraft. DOWTY ROTOL Ltd. Aug. 16, 1960, No. 28391/60. Class 4. [Also in Group XXIX] A fluid-pressure operated system, which may be used to operate the wing flaps, undercarriage and the like of aircraft, comprises a first selector valve 17 connected by a first non-return valve 25 to a pump 13, a second selector valve 18 connected by a second non-return valve 26 to a second pump 14, the selector valves being normally connected downstream to a first or normal service line 20 but being disconnectible therefrom and connectible to, by movement of the selector valves, a second or emergency service line 22, and third and fourth non-return valves 27, 28 connected between the emergency service line and the first and second selector valves 17, 18 respectively. The pump 13 is electrically controlled by a float switch 39 in a tank 15 connected to the pump by a line 11, and the pump 14 is similarly controlled by a float switch 40 in a tank 16. In the event of the line 11 bursting between the tank and the non- return valve 25, the drop in level of the fluid in the tank 15 actuates the switch 39 to stop the pump 13. Similarly, a burst in line 12 causes the switch 40 to stop the pump 14. If both lines 11, 12 burst, or if a burst should occur downstream of the selector valves in the service line 20, both switches 39, 40 on actuated to stop both pumps and to move the selector valves to disconnect them from the normal service line 20 and connect them to the emergency service line 22. Further operation of the system is then only possible by manual operation of emergency switches which override the switches 39, 40. The non-return valves 27, 28 prevent loss of fluid from the emergency line 22 if a burst occurs between the valves 25 and 27 or between the valves 25 and 28. The valves 25-28 may be incorporated into the construction of the selector valves 17, 18. The pumps may be driven by electric motors or engines connected to the pumps by disconnectible clutches. Excess pressure in the lines 11, 12 is relieved by valves 32, 33 connected to a return line 36.

Annular bearing members comprising carbon filaments disposed in a resin matrix are made by winding organic filaments on to an annular former which consists of two concentric graphite annuli located in one plane by graphite spacing rods, graphitizing the organic filaments, cutting the filaments adjacent to the inner and outer peripheries of the former, either before or after the graphitization step, removing each array of carbon filaments into a layer of resin or resin precursor and curing the resin with the filaments embedded therein. The organic filaments are preferably of polyacrylonitrile and are graphitized by first heating at 200-300‹ C. in an oxidizing or inert atmosphere, carbonizing in an inert atmosphere by heating above 1000‹ C., and graphitizing by heating above 2000‹ C. in an inert atmosphere. Each array of filaments may be removed from the former by applying a plate coated with resin or resin precursor to which the filaments adhere. The plate is made of a material to which the resin does not bond e.g. PTFE, or metal coated with a resin release agent. Further resin may be applied to the filaments on the plate, and resin at least partly cured while the layer is in position on the plate. A plurality of annular layers may be piled together to form a laminate after removal from the plates.
