Abstract: 710,719. Transformers and inductors. BRITISH THOMSON-HOUSTON CO., Ltd. Sept. 17, 1952 [Nov. 12, 1951], No. 26439/51. Class 38(2) An electric induction device such as a transformer or a ballast inductor for fluorescent lighting has a shell type core composed of co-axial coils of spirally wound strips of magnetic material forming an inner portion 2, two yoke portions 4 and an outer portion 6, one or more windings 3 being arranged within the space bounded by these core parts. When two or more windings are used, magnetic shunts, constructed similarly to the yoke portions 4, may be placed between them. The inner and outer core portions 2, 6 may, if desired, be wound in two pieces and arranged with an air gap between them. Since the flux travels at right angles to the planes of the laminations in the yoke portions the magnetic circuit will contain a number of small air gaps; thus a conventionally arranged air gap may be dispensed with. The yoke portions 4 may be wound on the inner portion as shown, or directly on the former 1 and may be enclosed within the outer portion 6 or extend to the external diameter of the outer portion. The device may be completely enclosed by a cover member.

Patent GB-854339-A (GB)
Title: Penicillamine production process
Inventor: RIDGWAY FRANK
Filed: 1957-08-22
Abstract: <FORM:0854339/IV(b)/1> Penicillamine hydrohalide is prepared by hydrolysing pencillin under alkaline conditions, decarboxylating the resulting penicilloic acid to form penilloic acid, e.g. by heating to a temperature in the range of about 75 DEG  to 95 DEG C. under reduced pressure, reacting the latter acid with a mercuric halide such as meruric chloride or a mercuric salts in the presence of halide ions, separating the resulting pencillamine/mercuric halide complex, decomposing the complex with hydrogen sulphide to form penicillamine hydrohalide, reacting this hydrohalide, preferably in a dry condition, with acetone, preferably substantially dry acetone, to form isopropylidene penicillamine hydrohalide complex, and decomposing said complex.  In the above process it is preferably to separate the pencilloic acid before the decarboxylation step, e.g. by extraction into an organic solvent and crystallisation from the solvent such as n-butanol, to hydrolize the penicillin in aqueous sodium hydroxide solution at a pH value in the range of about 10 to 12, to react the acetone and penicillamine hydrohalide at a temperature in the range of 0 DEG  to 56,5 DEG C., and to decompose the complex by heating in hydrochloric acid solution at a concentration in the range of about 1 to 3 normal under an inert atmosphere.  The concentration of pencillin is preferably in the range of about 2% to 10% weight for volume (c. g. s units) for the initial step.  The reaction with the mercuric halide or a mercuric salt is preferably carried out in the presence of sufficient sodium hydroxide to convert substantially the whole of the penilloic acid into a salt.  It is preferable to react the pencillamine halide with acetone in the proportion of about 1 part by weight of the amine to about 2 to 3 parts by weight of acetone.  A preferred method of carrying out the process is shown in the drawing.  A detailed example is given.

Abstract: 442,035. Compressed air engines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(Calkins, C. C. ; 1022, North Atlantic Street, Spokane, Washington, U.S.A.) Sept. 18, 1934, No. 26771. [Classes 122 (ii) and 122 (iii)] [See also Group XXXI] In a vehiclerocking machine, a beam 20 carrying jacks S rests on and is rocked by pistons in a pair of cylinders 6, 7, operated alternately by compressed air, the cylinders being each hung by trunnions between the ends of a pair of bars 2. Compressed air is admitted by a pipe 31, Fig. 2, to a distributing-valve cylinder 30 and thence is conveyed by pipes 32, 34 to the cylinders 6, 7 alternately, the supply being controlled by a pair of pistons 38, 39, mounted on a slidable rod 40 with reduced ends 41, 42. As each piston in turn in the cylinders 6, 7, subject to pressure, rises to the end of its stroke, it opens a spring-seated valve 43 allowing the air to return through a pipe 33 or 35 to the valve cylinder, there forcing the valve pistons 38, 39 endwise to reverse the action and eventually escaping through adjustable outlets 37. The valve 43 is unseated by a thrust pin 45 subject to the action of a lever 46 normally held by a pivoted catch 47. As the piston 13 rises, it compresses a spring 49 bearing on the lever 46 and eventually releases the catch 47 through a thrust rod 48, whereon the spring 49 imparts a blow to the pin 45 through the lever 46, opening the valve 43 sharply.

Patent GB-1211838-A (GB)
Title: Focusing device for an optical instrument
Inventor: KOEBER HENRY JACOB JR
IPC: G03B13/20
Filed: 1969-05-28
Abstract: 1,211,838. Focusing devices. BELL & HOWELL CO. May 28, 1969 [June 7, 1968], No.27019/69. Heading G2A.  In the device of Specification 1,208,388, in  which, when a camera is pointed at the foot of a subject to be photographed, the movement of a freely suspended pendulous member automatically adjusts the focus of the camera objective, means are provided for compensating for variations in the height of the operator. Since this height forms the vertical of a right-angled triangle, of which the optical sighting axis forms the hypotenuse, and the subject-to-camera distance the base, accurate determination of the latter will depend on accurate determination of the height. Since this will vary according to the height of the operator, the invention provides compensating means for this variation. The pendulous member 44 swings on a pivot 46, which is itself secured to an elevator member 106. Member 44 can be disabled, if required, so that focusing adjustment can be made manually Fig. 5. A control lever 66, mounted on a shaft 62, is pivoted upwards into the position of Fig.5. With it moves another lever 72 having a tang 74 at one end, the tang now coming out of a cut-out portion 76 in an actuator member 60, also mounted on shaft 62. Lever 72 engages against a stub 80 staked to pendulous member 44, so pushing it out of engagement with a positioning pin 48 which controls the axial position of the lens cell 24. This can now be adjusted manually, by a knob 84 reading against a distance scale Fig.1 (not shown), which, by means of a rack and pinion arrangement 88, 90, 92 pivots member 60 about shaft 62, a cut-out portion 78 engaging and moving pin 48. To set the device for automatic focusing, levers 66 and 72 are pivoted clockwise from the Fig.5 to the Fig.4 position. Lever 72 disengages from stud 80, and tang 74 re-enters cut-out 76, pushing it clockwise, and hence pin 48 is pushed by cut-out 78 to one end of its range of movement. Pendulous member 44 can now swing freely under gravity, on its axle 46, in response to the inclination of the lens cell 24. Positioning pin 48 is pushed across (to the right, as seen in Fig.4) by a spring 52, until it engages a cam surface 50 of member 44, thus positioning the lens cell according to the orientation of member 44. Vertical adjustment of member 44 to compensate for height variations is accomplished by rotation of a height adjustment knob 30. This is supported in the main support plate 56 by an axle stud 98, which passes eccentrically into a bearing 100, the bearing rotating within a carrier ring 102 of elevator member 106. Thus as knob 30 is turned, elevator 106, and hence axle 46, and hence pendulous member 44, is raised or lowered.

Title: Camera with focusing mechanism using triangulation principle

IPC: G03B13/20
Filed: 1969-05-28
Abstract: 1,218,697. Camera focusing. BELL & HOWELL CO. May 28, 1969 [June 7, 1968], No. 27023/69. Heading G2A. A camera contains a free-swinging pendulous member 50, which remains in its original position, under gravity, when the optical axis is sighted at the foot of a subject to be photographed Fig. 2 (not shown), the angle it then makes with the optical axis being indicative of the distance of the subject, and being used to set the focus accordingly. As shown, the pendulous member 50 is semi discshaped, having a cam surface 58 and is pivoted on an axle 52. The objective lens 24 is mounted in a housing 14 which engages by screw-threaded means Fig. 1 (not shown) with the camera housing, and so can be given an axial focusing movement by rotating it. The rear (inner) part of housing 14 ends in a cam surface 40. A spacer rod 72 is slidably supported in two ears 74 extending from a fixed bracket 76, and is urged by a spring 80 so that its forward end 82 abuts against cam surface 40. Cam 40 is normally set to allow rod 72 to move sufficiently far forward for its rear end 90 to be out of contact with member 50 Fig. 3 (not shown), so that member 50 can swing unimpeded. When the camera is tilted into its sighting position Fig. 4, pendulous member 50 swings under gravity to the relative position shown. The lens housing is now adjusted axially so that cam surface 40 pushes rod 72 in a rearward direction, against the spring, until its rear end 90 abuts cam surface 58. This is so fashioned that the objective is now in focus for this particular inclination of the optical axis, i.e. the corresponding subject distance. Although it is not necessary to ascertain the distance as an actual numerical value, this may be read off on a scale marked on the lens housing. Since the height of the observer's eye above the ground is a parameter in the calibration of the arrangement, this is assumed at an average value of 5' 8". Since the rod 72 is aligned with the axle 52, its abutment against member 50 has at the same time a locking effect.
