Title: Electro-sonic apparatus
IPC: A61N1/32
Filed: 1958-01-24
Abstract: 881,837. Electromedical apparatus. DE GROFF, M. E. Jan. 24, 1958 [Jan. 31, 1957], No. 2487/58. Class 81 (2). Electromedical apparatus by which a patient may be treated simultaneously by ultrasonic mechanical vibrations and low-voltage oscillations comprises a lower voltage generator and an ultrasonic generator and applicator means connected with each generator. The low-voltage generator includes an oscillator tube 46 (Fig. 6) and an electric timing motor 48 energized through an input transformer 81 from a mains supply to which the device is connected by a plug 16 (Fig. 7). Pairs of electrode pads 40, 42 (Fig. 6) for applying low-voltage oscillations to the patient are connected to the oscillator tube 46 through a transformer 50, a selector switch 64 (Fig. 7) and microswitches 56, 58, 62, 70, 72, (Fig. 6) which are controlled by cams 52, 54, 60, 66, 68 respectively, the cams being rotated by the motor and being shaped so that the frequency of opening and closing of each microswitch differs from the others. According to the setting of the selector switch the microswitch and other components of the apparatus are selectively brought into the pad circuits so that one or both pairs of pads are supplied with electrical oscillations in pulses of 1 second or 3 seconds duration, as " tetanise " current (i.e. audio-frequency oscillations superimposed on rectified half waves), as " surge " current (i.e. " tetanise " current interrupted for periods of 4 seconds in every 10 seconds) or as pulses, " tetanise " and " surge " current successively in 3-minute cycles. The ultrasonic generator includes a full-wave voltage doubler 20 (Fig. 8) and an oscillator 18 which are energized by the mains supply through a transformer 24. The output of the ultrasonic generator is applied to a quartz crystal 22 (Fig. 9) in a sound head 12 through a coaxial cable 26. The sound head easing may be connected through the casing of the apparatus to one pad of one pair of pads and used with the other pad of that pair to apply electric oscillations to the patient. Either generator may be switched off so that the patient may be treated with either electrical oscillations or mechanical energy alone.

Abstract: 646,122. Subaqueous signalling-apparatus. STEVENS, A. H. (Submarine Signal Co.). Feb. 10, 1944, No. 2517. [A Specification was laid open to inspection under Sect. 91 of the Acts, April 23, 1946.] [Class 40 (iv)] [Also in Group XL (b)] A subaqueous signalling device for transmitting or receiving compressional waves comprises a number of piezo-electric crystals of the Rochelle salt type with end surfaces perpendicular to the compressional axis and side surfaces perpendicular to the end surfaces, the crystals being mounted on a backing-plate within a casing and arranged to support the crystals at points on opposite side surfaces and also serving to provide spatial separation of the crystals of the assembly. The crystals are cut from rectangular crystals of polyhedral cross-section so that the diagonal axis at. right-angles to the electric axis which exhibits maximum elongation and contraction becomes the compressional axis in the cut crystal. The single unit, Fig. 1, formed by a composite crystal 1 has end-plates 6, 7 perpendicular to the compressional axis and electrodes 2, 3 extending along opposite side surfaces. The crystal unit shown is clamped by members 4, 5 and the effective vibration is in the direction of the tierods 9 connecting the plates 6, 7. As shown in Fig. 2, rows 18 ... 25 of crystals are mounted in grooves 11 ... 17 in the backing plate 10, the individual crystals having electrodes 29 and the rows being provided with spring plates 26 forming connecting members between the rows and the source of electrical supply. The rows of crystals, which are separated by the ribs formed between adjacent grooves, can be connected in series, parallel or in series-parallel. The casing, Fig. 3 (not shown), has a rubber diaphragm clamped between a wall integral with the plate 10 and a flange on the casing 33 which is mounted in the wall of the vessel and is provided with a rear cover-plate. In a modified arrangement, Figs. 4, 5, the crystal units 42 are arranged radially on the backing-plate 43 with their ends fitted into notches 47, formed in a central boss 45 and in notches 50 in a ring 48 which may be integral with the plate 43. Electrode members 51 and 52, engaging the sides of the crystals, act as supports for the crystals, and the leads are taken through a stuffing-box 55 mounted in the closure-plate 54 of the casing. The diaphragm 40 is clamped to the casing 33 by a threaded ring 41. When the ends of the crystals do not contact the diaphragm 40, castor oil or other suitable liquid is introduced into the casing through an opening in the plate 54, and the plate 43 is provided with suitable holes for the passage of the liquid to the crystal enclosure.

A flying-spot scanning system of the kind in which the object to be examined is scanned by two scanning beams scanning adjacent lines (e.g. in particlecounting apparatus employing a " guard beam " technique) comprises a flying-spot light source S (which may be a cathode-ray tube) and a first optical system including a lens system L1 and a refracting element R the latter being arranged to refract light from spot S which enters the lower half of L1 in such manner that a light spot S2 is produced (in plane IP1) which is displaced from the light spot S1 (also in plane IP1) due to light from spot S which passes through the upper half of L1. When the apparatus is employed for particle counting a slide containing the latter is positioned in plane IP1 and the emergent light gathered by a second lens system L2 which produces discrete illuminated areas in plane IP2 due to the light spots S1 and S2. This illumination is then directed selectively by means of mirrors M1, M2 on to photo-electric cells PE1, PE2 respectively the signals generated by which may be employed to obtain a count of the particles.

Title: Improvements in or relating to casting
Inventor: BEECH SAMUEL ROBERT
IPC: B29C33/00
Filed: 1959-01-28
Abstract: 915,523. Moulding lenses. COMBINED OPTICAL INDUSTRIES Ltd. Jan. 28, 1960 [Jan. 28, 1959], No. 3044/59. Class 87(2). A lens casting mould assembly comprises a jig arranged to receive a first lens die in predetermined position, a mounting member accurately locatable on the jig and arranged to support a second lens die for axial movement relative to the first die, means for biasing the second die against the mounting member to define accurately the position of the second die initially, and guide surfaces on the jig to determine the position of the second die transversely of its axis during its axial movement. In a preferred embodiment, Fig. 4, the jig 35 has two die-carrying parts 36, 37 upstanding from a base 38. Part 37 has a large circular hole 40 to receive a first lens die 39 which is held in place by a cap 41 and a clamp 42, the die being held to the cap 41 by a threaded bolt 43 passing into the die while a shoulder 44 on cap 41 engages with the outer surface of part 37. Part 36 is formed with a cylindrical recess 47 which is machined to receive accurately the second die 48 so as to face die 39. Die 48 can move axially within recess 47 but is normally held against the back of the recess by a spring 51, the ends of which abut against part 36 and the head 52 of a bolt 50 which passes through part 36 and is threaded into die 48. A rubber band 54 overlies the edge of the mould cavity formed between the die surfaces 53 and is either pulled back when the cavity is to be filled, or pierced by means of a hypodermic needle. Polymerization of the casting material, e.g. di-ethylene glycol bis (allyl carbonate) is affected by placing the filled mould in an oven. Where the lens to be cast is required to have a primatic component, one of the parts 36, 37 may be adjustable angularly with respect to the other, e.g. by hinging one part to the base 38. The bias applied above by spring 51 to restrain die 48 against part 36 may alternatively be provided by having part 36 magnetised, or by gravity with the axes of the dies 39, 48 vertical instead of horizontal as shown.
