Title: Improvements in Method of and Means for Measuring the Hardness or Softness of Eyes.
Inventor: MCLEAN WILLIAM
IPC: A61B3/16
Filed: 1916-05-04
Abstract: 103,583. McLean, W. May 4, 1916. Eye instruments and appliances. - Relates to apparatus for determining the health or otherwise of the eve by measuring its hardness or power of resisting pressure. The eye being directed upwards, a tubular frame 3, containing an axial weighted plunger 18, 40, Fig. 1, carried by a frame 1 with handles 17 for the operator, is allowed to rest vertically upon the eye ball. The lower end of the plunger passes through and is centred by guiding-screws within the tube 3, which has a flared base 5 of similar contour to the eyeball, and its upper end 24, Fig. 2, as it is forced relatively upwards by the eyeball, raises a roller 28 upon a pivoted arm 26, the roller also lifting, through an intermediate lever 30, a lever 31 carrying the index pointer 32 moving over a scale 33. An adjustable stud-and-slot connexion 36, 35 between these levers enables the instrument to be set accurately for zero. Guiding stop-flanges 20, 21 are provided, and also a sleeve 6 capable of sliding upon the tube 3 within limits determined by a flange 2 at the extremity of the frame 1 and by the flared end of the tube. The friction of the plunger within the tube is diminished by means of adjustable studs against which it bears laterally. Handles 17 attached to the slidable sleeve 6 enable the operator to lower the apparatus until the tube 3, with the whole of the rigid parts, is borne by the eyeball. The extra indentation made by the weighted plunger 18 will then be indicated by the pointer, and is a measure of the hardness.

Title: Improvements in or relating to magnetic compasses
IPC: G01C17/28
Filed: 1941-05-21
Abstract: 549,528. Flux-gate compass systems. BENDIX AVIATION CORPORATION. May 21, 1941, No. 6552. Convention date, May 21, 1940. [Class 40 (i)] [Also in Group XXXVI] An earth-inductor compass comprises a magnetic device 10 adapted to be fixed to a ship or aircraft and comprising a number of symmetrical limbs 11, 12, 13, converging on a central ring 14 having an exciting winding 18 energized from an A.C. source 21. The limbs carry windings 15, 16, 17 connected to windings 25, 27 on a "selsyn" motor 29, the rotor 30 of which carries a winding 31. In use, the inductor is arranged in a horizontal plane and preferably on a gyroscope, Fig. 3 (not shown), and the source 21 is arranged to saturate the ring 14 twice per cycle, so setting up a double-frequency alternating current in the windings 15, 17 and 25 .. 27. The resulting current in winding 31 due to a deviation # of the inductor 10 is amplified at 34 and fed to one winding-pair 37 of a two-phase induction motor 38, the other winding pair 39 which is energized from source 21 through a frequency-doubler 40, so causing the rotor 45 to drive through gearing 46 the shaft 47 carrying rotor 30 and the pointer 48, until the rotor 30 again reaches a null position. The rotor and pointer are thus caused to follow up the movement of the inductor and indicate the angular disposition thereof. With stronger fields the torque-amplifier comprising the amplifier 34, motor 38, and gearing 46 can be dispensed with, Fig. 4 (not shown), the rotorwinding 31 being connected directly to the output of the frequency-doubler 40. The latter is unnecessary if source 21 is an interrupted D.C. one, or if the A.C. source acts in opposition to a D.C. saturating bias. The material of inductor 10 may be soft iron, silicon steel, "Permalloy" or"Mumetal" (Registered Trade Mark), the latter two being preferred owing to the sharp bend in the saturation curve and resulting greater induced voltage. In Fig. 2 the limbs 11<SP>1</SP> .. 13<SP>1</SP> are connected directly to one another without the use of a ring, and the parts of the exciting winding 18<SP>1</SP> are wound on the limbs. Specification 537,514, [Group XXXVI], is referred to.

Title: Improvements in or relating to machines for slicing meat, bacon, or the like
IPC: B26D1/143
Filed: 1936-03-05
Abstract: 471,680. Slicing-machines. SIDWELL, R. R. March 5, 1936, No. 6686. [Class 28 (ii)] To enable slices to be cut on the bias, a disc knife reciprocating table machine is provided with an attachment which is secured to the feed table and comprises a sloping auxiliary feed table B, on which the bacon can be clamped and fed in an inclined position to the knife, and an extension plate G, slidable in guides g<1>, g<2> in the auxiliary table structure, which supports the overhanging piece of the bacon. The table B is supported on walls C, D, stiffened by stays C<1>, C<2> and having outstanding clips E whereby the table is engaged with the usual clamp pillars of the machine. The clamp comprises a bent metal rod F hinged at each end to the walls and having prongs f<1> and upwardly projecting parts f<2> which serve as handles. The existing clamp of the machine may be brought down on the clamp F, the projections f2 being received in the channel of the clamp bar, the rear edge of the usual clamp bar engaging the bacon and supplementing the action of the clamp F. The bacon is steadied on the table B by prongs b<1>. The front edge g<4> of the plate G is serrated and a projection g<3> holds the bacon against the cutting pressure of the knife. The edge g<4> is always close to the cutting plane to ensure a clean cut, this being effected by the sliding of the plate G in the guides g<1>, g<2> during the feed motion. This sliding is produced by an arm, attached to the plate and extending rearwardly, which carries, at its end, a roller which is constrained to move in a line defined by vertical guides secured to the reciprocating carriage. Alternatively, the plate G is secured by links to a shaft journalled in the walls C, D and operated by an arm which contacts with a cam on the reciprocating table. Specification 436,246, is referred to.

Title: Improvements in and relating to shaping machines
IPC: B23F5/12
Filed: 1943-04-28
Abstract: 570,490. Attachments for shaping curved surfaces. CALDWELL, F., and METROPOLITAN-VICKERS ELECTRICAL CO., Ltd. April 28, 1943, No. 6724. [Class 83 (iii)] In a shaping attachment for lathes or other machines which permit the work to be indexed about an axis, a saddle 3 is provided for adjustable attachment to the machine bed 4, two pedestals a being mounted on the saddle and provided with guides c for rams d carrying tool assemblies l, m. The pedestals are angularly adjustable to enable the rams to reciprocate in paths inclined to the axis of the work y<1> for the formation of surface grooves or slots x, y therein and, for producing dovetailed slots, two tools are arranged on each ram, one being carried by each of the tool boxes j, k which are fed periodically along inclined guides on a bracket g to generate the required cross-section of slot. The tools l, m are set one behind the other so as to cut freely and may be fed individually or by a common ratchet feed n. The bracket g is slidable on guides e on the end of the ram perpendicular to the direction of reciprocation thereof to provide for withdrawing the tools from the work before the return stroke of the ram. The bracket g and ram are reciprocated by cams driven from an electric motor p flange-mounted on the pedestal a, the cams being designed to give a pause at each end of the ram stroke whilst the tools are being advanced or withdrawn and to maintain the bracket stationary on the ram during the cutting and return strokes of the latter. For setting-up the cams may be rotated by a handle q and when the desired depth of groove has been cut the motor p is stopped by an adjustable abutment r on the bracket g engaging a switch t. The machine may produce slots in frusto-conical surfaces of the work, as shown in Fig. 1, or in flat surfaces formed on frusto-conical work, or the guides c may be curved so as to produce curved slots in the work.

Title: Improvements in or relating to pulse code modulation decoding systems
IPC: H03M1/00
Filed: 1957-03-01
Abstract: 815,536. Pulse code modulation circuits. WESTERN ELECTRIC CO. Inc. March 1, 1957 [March 28, 1956], No. 6912/57. Class 40(5). In a pulse code demodulator of the kind disclosed in Specification 657,251, each code pulse circulates 2 (or more) times round the feedback loop, or up and down the delay line in order to increase (or decrease) its amplitude the required 2, 3, &c., times according to whether the code is binary, ternary, &c. The additional journey through the circuit produces pulses of opposite polarity to the original interleaved with the original. These extra pulses are not included in the final sampling; but by substantially eliminating the D.C. component of the pulse train they simplify the circuit requirements. In one embodiment, incoming binary code pulses, regenerated at 7, are passed by a biased varistor gate V2, V3 to a grounded emitter transistor amplifier 27 having a feedback loop R6, R2 and delay device 5. The delay is half the interval between code pulses, and the loop gain is #2 of 1/#2 according to whether the code pulses are in descending or ascending denominational order. Each pulse then circulates twice to change its amplitude by 2, by which time it is sufficiently delayed to coincide with the next code pulse, and the combined pulse circulates until all the pulses of the code group have been similarly handled. The final pulse amplitude is sampled by a transistor 26 controlled by a timer 8, which also biases the amplifier 27 to cut-off to prevent uncontrolled regeneration. In a second embodiment, Fig. 4 (not shown), the incoming code pulses are applied to a delay line and are repeatedly reflected from end to end of the line with a phase reversal at the far end of the line. The delay line introduces a loss of #2 and a time delay of half a code pulse interval for each to and fro journey. At the end of each code group the resulting pulse amplitude is sampled. It is stated that in the general case of m-valued 1 pulses the transmission characteristic is -, m2r T and the time delay is -, where r is any integer, 2r and T is the interval between pulses. Specification 815,535 also is referred to.

Abstract: 701,751. Colour television. PYE, Ltd. March 27, 1952 [March 27, 1951], No. 7071/51. Class 40 (3) In a colour television system employing field sequential transmission, the colours are repeated in the sequence red, green, blue, green, red, &c. and the line scanning is effected in an eight-fold interlace as indicated in Fig. 1 whereby the green image is reproduced with twice the definition of the red or blue image. If the total number of lines is 801 and the field frequency is 200 cycles per second, each field contains 100# lines and there are 25 frames per second, 400¢ lines of each frame being green 20 being red and 200 being blue. At the transmitter and receiver, Fig. 2 (not shown) colour separation is effected by rotating colour discs driven in correct phase relationship with the scanning. At the receiver at 20 Mc oscillation keyed on and off at half field frequency is applied to the cathode-ray tube so as to elongate the scanning spot in a direction normal to the lines during red and blue fields and mask the line structure. The reproduced green image is subjected to twice the attenuation of the red or blue image to equalize the brightness. When received on a monochrome receiver, the green image appears twice as bright as the red or blue giving an overall system characteristic similar to the human eye.
