Title: Improvements in or relating to friction-damped buffers
IPC: F41A25/10
Filed: 1960-07-15
Abstract: 907,408. Buffers; friction-type shock absorbers. MAIER, K. W. July 15, 1960, No. 24653/60. Class 108(3). A friction damped spring unit comprises a pair of nested helical springs 8, 9, Fig. 3, having mutual camming surfaces 14, 15 which cause the outer or inner faces 10, 11 of the springs to be radially compressed into frictional engagement with the walls 13 of the spring casing 3 or the outer surface 12 of the inner member 2. The damping unit is disposed between the load applying member 16 and a compression spring 6 which may be integrally formed with one of the springs 8, 9. In modifications the overall length may be reduced by disposing the spring 6 at least partially within the springs 8, 9 which are supported by a flanged cup. Additional resilience may also be provided by providing a thin outer casing 23, Fig. 11, which is slotted at 24 to permit radial expansion under load. The casing 23 may be reinforced by a sleeve 25 of elastic material such as circumferentially wound bonded glass fibre.

Title: Non-pigmentary titanium dioxide granular material and method of making same
IPC: C03C1/02
Filed: 1965-06-10
Abstract: The invention comprises non-pigmentary TiO2 granules having a bulk density of 0.8-1.7 g/c.c. and size - 10 to + 400 mesh (Tyler), with at least 75% + 325 mesh, and consisting of aggregated particles of 0.05-0.15 m .  The TiO2 may be prepared by hydrolysing a soln. of Ti(SO4)2 containing 100-180 g/l. of Ti calculated as TiO2, and a H2SO4:TiO2 ratio of 1.7-2.3: 1, filtering the soln., washing, bleaching and calcining the hydrated TiO2 at 800-1000 DEG  C. and sub-dividing the formed nodules into granules of size - 10 to + 400 mesh.  The nodules may be of 1/16 inch to 1/2 inch in diameter. The Ti(SO4)2 soln. is prepared by treating titaniferous material e.g. ilmenite ore, with conc. H2SO4, dissolving the residue in an aq. media, reducing Fe3+ by the addition of pig iron, and clarifying the soln.  Claims 5, 6 and 7 disclose methods of hydrolysis of the Ti(SO4)2 soln. by dilution or by adding a colloidal soln. of TiO2 and heating.  Glass compositions containing the TiO2 of the invention are described.  In example Ia, 4 parts TiO2 are dry blended with 68.7 parts SiO2, 0.5 parts Al2O3, 23.1 parts CaCo3, 13.7 parts NaNo3, 14 parts Na2Co3 and 1 part Al2O3, and heated to 1500 DEG  C. for 1 hour. Example IB is prepared as above but with 56 parts SiO2, 20 parts Al2O3, 31.4 parts MgCO3 and 9 parts TiO2.

Title: Improvements in and relating to electric transformers and other stationary electric induction apparatus
IPC: H01F27/30
Filed: 1919-10-09
Abstract: 157,521. British Thomson - Houston Co., Ltd., (General Electric Co.). Oct. 9, 1919. Transformers.-In stationary electric induction apparatus, such as transformers, the coils 14 are mounted between upper and lower supports 23, 17, and the core parts 10 are suspended from the upper support in such a manner as to compress the windings between the supports. The lower support 17 is mounted on rods 19 secured to the base 18. The upper support is constituted by the upper core clamps of the apparatus, the lower core clamps loosely engaging the rods 19. Springs 27, Fig. 2, mounted on rods 29 fixed to the base may be placed between the upper support and fixed abutments 28 carried by the rods. The weight of the core parts acts in conjunction with the springs to delay and smooth out the shock of the repulsive forces in the windings occasioned by transient disturbances, such as short-circuits. In place of springs, resistance devices may be used which allow the weight of the core to bear on the windings to keep them tightly compressed and to take up shrinkage, but which resist movement under repulsive forces. In one arrangement, Fig. 3, a pair of dogs 31 pivoted to the top core clamp 23 are resiliently held in engagement with grooves 32 on the rod 29 by a spring 33. An additional dog 34 may be carried by the lower core clamp. In another arrangement, the upper core clamps carry conical receptacles surrounding the rods 29 and containing balls which exert a wedging action to resist any upward thrust.

Title: Improvements in or relating to electrical generator systems
Filed: 1956-08-14
Abstract: 796,536. Fluid-pressure servomotor-control systems. GENERAL MOTORS CORPORATION. Aug. 14, 1956 [Aug. 29, 1955], No. 24820/56. Class 135. [Also in Group XXXV] In an electrical generating system comprising a variable-speed prime mover driving an alternating current induction generator supplying an electrical load, means.are provided connected to the generator output and responsive proportionally to the output voltage and inversely proportionally to the frequency thereof for controlling the prime mover speed. By this means the output voltagefrequency ratio is maintained constant. As shown, a self-excited squirrel-cage induction generator 10 is driven by a prime mover 12 and supplies power to induction motors 14, 141. A control voltage is derived from neutral point 46 and tap 21 of winding 20 of the stator windings and is applied to a winding 52 which is predominantly inductive and controls an armature 58, the current in winding 52 thus being a function of the line voltage-frequency ratio. The armature 58 is connected by a rod 80 with a valve 72 having a central annular chamber formed by raised portions 74, 76, and operating against a spring 86, the valve being provided with damper springs 88, 91. A piston 98 in a cylinder 64 is operated by hydraulic pressure applied via inlet 93, and valve 72. The cylinder 64 is provided with a main fluid passage 92, and a pair of restricted passages 94, 96. The valve cylinder 66 has an exhaust passage 95. A governor 104 of conventional type is adjusted by movement of the piston 98, through lever 110 and spring 116, and through speed control means 18 controls the prime mover 12. In operation, assuming that the generator is started under no load, initially the control current is zero and the valve 72 is in the left-hand position uncovering the restricted passage 96 and main passage 92, the force exerted on the piston causing the prime mover speed to increase. As the speed is increased the voltage-frequency ratio increases, thus increasing the control current and causing valve 72 to close the passage 92 followed by the passage 96. In this position the spring 116 exerts a force via lever 110 on the piston causing a slight amount of oil leakage past the piston, thus causing a slight reduction in engine speed and permitting the valve to uncover the restricted passage 96, this action being repeated at a high rate. If an induction motor 14 is connected across the generator output terminals the engine speed decreases, causing a decrease in the control current and the valve to uncover passage 96 and possibly passage 92 to permit a higher rate of correction. When the load is decreased the speed increases momentarily and the valve uncovers passage 94, permitting the pressure to be released via passage 95 and if the decrease is sufficient, passage 92 also is uncovered to give a higher rate of correction.

Title: Improvements in or relating to the formation of cakes of soap
IPC: C11D13/28
Filed: 1923-10-11
Abstract: 224,682. Jolas, O., and Weil, K. Oct. 11, 1923. Punching and perforating machines.-In the formation of cakes of transparent or other soap containing an advertisement card or slip the card is inserted in a slot in the cake before the cake is pressed to its final form. A roughly shaped cake g<1> is dropped from a magazine into an open-bottomed frame F, and is slit to the desired depth by a blade e on a carriage c reciprocated on rails b by a lever d<2>. The frame is then turned on or with a spindle f<2>, and the bottom card i in a magazine I is inserted into the slit either 'by rollers i<2> or by hand. The frame is next turned to position D, where the slit is closed and the cake shaped by a press p, a ledge a<1> on the supporting table A closing the end of the frame F. The cake is detached from the matrix p<2> by a central portion p<3> lifting with the operating lever of the press; it is then carried round by the frame F until it drops through a hole E in the table. The frame F and the slotting, card-inserting, and pressing devices may be operably connected, and cams may be used to control their movements. Reference has been directed by the Comptroller to Specifications 4936/86, 6355/90, 23137/07, and 27448/13, [all in Class 91, Oils &c.].

Title: Improvements in or relating to no-back couplings
IPC: F16B1/04
Filed: 1959-07-23
Abstract: 895,316. One-way brakes. CURTISSWRIGHT CORPORATION. July 23, 1959 [July 24, 1958], No. 25373/59. Class 103 (1). A no-back coupling has a stationary drum S, Fig. 1, relatively rotatable input and output members I, O and a helical friction spring 30 connected at end 27 to member O, having its coils O<SP>1</SP> normally in one-way self-locking contact with drum S, and at least one of its end coils I<SP>1</SP>, T<SP>1</SP> in one-way locking contact with a drum 10 on member I, so that angular movement of member I to increase the locking of spring 30 on to drum 10 tends to cause the coils O<SP>1</SP> to overrun on drum S. A stem 11 of member I projects into the sleeve 24 of member O formed of two members 15, 16 tightly fitted into a bearing 20 rotatably received in drum S, the stem 11 carrying a pin 31 projecting into slots in sleeve 24. The spring 30 anchored to members 15, 16, frictionally engages members 16, S and a drum 10 of input I. Clockwise rotation of member I causes pin 31 to engage the ends of the slots to rotate member O, the spring 30 being contracted by member 16 out of engagement with drum S to enable free drive to member O. Normally spring 30 prevents counterclockwise rotation of member O, but counterclockwise rotation of member I causes spring 30 to contract on to drum portion 10 and out of engagement with drum S to permit member O to overrun spring 30, e.g. to lower a load in a hoist. The spring 30 may be provided with a tooth to engage serrations on drum 10 to avoid the necessity of preloading the spring on to this portion. In a modified brake in Fig. 5, the input member I<SP>3</SP> has a drum 51 and carries an input member I<SP>2</SP> rotatably mounted in fixed member S<SP>2</SP>. A brake spring 54 bridges drum 51 and a drum 52 of output O<SP>1</SP> and an oppositely-wound spring 56 engages drum 101 of member I<SP>2</SP>, the member S<SP>2</SP> and the output member 16<SP>1</SP> of output O<SP>1</SP>. To raise a load fixed to output O<SP>1</SP>, a crank 44 on member I<SP>3</SP> is rotated counterclockwise, to contract spring 54 on to drums 51, 52 to drive output O<SP>1</SP>. When crank 44 is rotated clockwise the drum 51 overruns spring 54. When pin 45 of crank 44 is withdrawn and the lug and recess 42, 43 of member I<SP>2</SP> and crank 44, respectively, are engaged, clockwise rotation of crank 44 contracts spring 56 on to drum 10<SP>1</SP> and out of engagement with member S<SP>1</SP> to permit the output O<SP>1</SP> to overrun spring 56, and permit lowering of a load. Opposite rotation of crank 44 causes drum 10<SP>1</SP> to overrun spring 56.
