Abstract: 774,689. Deunatomes. CONCENTRIC MANUFACTURING CO., Ltd., and BURKE, H. March 21, 1955 [Feb. 16, 1954], No. 4469/54. Class 81(2) A deunatome comprises a frame having a handle and supporting an oscillatable knife, a base-plate to bear upon the skin and a pressure member pivotally attached to the frame and angularly adjustable relative to the knife-edge by a single micrometrical screw device. The knife 20 having a cutting edge 22 is supported on a carriage 4 and is reciprocated transversely, relative to the frame, on bars 5 by means of a crank-pin 12. The crank-pin 12 is arranged eccentrically of a shaft 9 which is in the handle 7 and is connected with an electric motor by a flexible shaft (not shown). A ribbed base-plate 3 which bears upon the skin when the deunatome is in use is secured to the frame. A pressure member 23 is provided with rearwardly directed arms 24 by which it is pivoted to the frame. A screw 27 engages in a boss 28 arranged centrally of the pressure member 23 and passes through a cross-bar 26 against which its head 29 bears. Rotation of the head 29, which carries a micrometer scale used in conjunction with an index on the cross-bar 26, adjusts the position of the pressure member 23 relative to the cutting edge 22 to determine the thickness of the skin to be. cut. After adjustment of the pressure member 23, the screw 27 is held in position by a spring-pressed plunger 31 secured to the cross-bar 26 bearing against a serrated wheel 32 fixed to the screw 27. Guide plates 33 are provided at each side of the frame to determine the width of the skin to be cut. These guide plates may be adjustable to increase or decrease the distance between them. In an alternative construction, the device is powered by an air motor housed in the handle.

Abstract: 874,896. High-frequency discharge tubes. ASSOCIATED ELECTRICAL INDUSTRIES Ltd. May 13, 1959 [Feb 13, 1958], No. 4782/58. Class 39(1). In a multi-cavity magnetron, magnetron or other type travelling wave tube, or in a particle accelerator, the resoncavities are formed by slotted laminae, as in Figs. 1 and 2, which are superimposed, as in Fig. 3, so that portions of adjacent slots overlap. This is in order to obtain improved mode separation arid a dispersion characteristic such that the group velocity for the fundamental component is in the same direction as the phase velocity. The invention has particular application to amplifiers. The resonant structure may form a complete ring, a portion of a ring, or may be linear. The laminae are connected together at or near the open ends of the slots, but may also be connected together at their outer peripheries.More than two laminations can be used, inverted alternately or in packets and the number of laminations of Fig. 1 form may be different from those of Fig. 2 form. The resonant structure may comprise two coaxial annuli each .consisting of a stack of similarly shaped and positioned laminations.

Abstract: 1,035,763. Ultrasonic testing. UNITED KINGDOM ATOMIC ENERGY AUTHORITY. Feb. 1, 1963 [Feb. 7, 1962], No. 4793/62. Heading H4D. In an arrangement for measuring a physical characteristic of a body which is related to the velocity of sound in the body, such velocity is determined from the echoes produced by two spaced echo producing regions D and E in the body when ultrasonic waves are launched into the body in the form of pairs of pulses the pulses of each pair being separated by time intervals which, alternately, are greater than and less than a variable time interval To which is adjusted to equal twice the transmission time T for ultrasonic waves between the echo producing regions, i.e. To=2T. In operation, the echo from the second region E produced by the first pulse of a pulse pair of spacing To + # precedes and combines with the echo from the first region D produced by the second pulse of said pulse pair to form a first composite echo and the echo from the second region E produced by the first pulse of an adjacent pulse pair of spacing To - # lags and combines with the echo from the first region D produced by the second pulse of the adjacent pulse pair to form a second composite echo displaced from the first composite echo, the required condition of To=2T being obtained by adjusting the value of To to equalise the amplitudes and shapes of the first and second composite echoes as displayed on an oscilloscope 17. The physical characteristic may be temperature or physical phase (e.g. liquid or solid). In the case of temperature measurement the body comprises a molybdenum or rhenium probe 5, 7, of known sound velocity/ temperature characteristic, the two echo producing regions of which are constituted by a shoulder D and by the end E respectively. The probe is acoustically matched by a tapered rod 4 of graphite or alumina to a magnetostrictive member comprising a nickel tube 1 in which the ultrasonic pulse pairs are induced by means of a coil 2 and from which echo pulses are derived by means of a coil 3. Various alternative forms for the probe are described with reference to Figs. 3A to 3D (not shown).

Abstract: 220,340. Barber, S. H. Feb. 21, 1923. Thermostats.-In an arrangement for controlling the temperature of incubators or similar chambers heated by means of circulating hot water or air of the kind employing a heater 2 traversed by vertical flue 3 below which a lamp or other heating means is disposed, an openended auxiliary flue 9 depends into and is spaced apart from the wall of the flue 3 and is movable under the action of a thermostat towards or away from a damper 34 located above the upper end of the auxiliary flue. The position of the auxiliary flue may be regulated either by a single thermostat influenced by the temperature in the incubator or by the temperature of the heating- fluid, or partly by one of these methods and partly by the temperature of the external atmosphere. Similarly, the damper 34 may be fixed, or it may be movable and its movements thermostatically controlled by any of the methods referred to in connection with the auxiliary flue. In the construction shown the heating of the incubator 6 is effected by means of hot-water circulated from the heater 2 by connecting-pipes 7, 8. Disposed in the pipe 7 is a metal vessel 20 covered by means of a thermostatic capsule 25, above which is located an insulating washer 26 and a further capsule 27. Another capsule 33 is supported on rods 16, and the movements of the capsule 25 exposed to the temperature of the heating-fluid, and' of the capsules 27, 33 exposed to the atmospheric temperature are communicated by means of rods 29, 32 to a counterbalanced lever 21 pivoted at 13 and carrying the auxiliary flue, 9. The damper 34 as shown is not thermostatically controlled, but is carried by a pivoted arm 35 which normally abuts against a stop 37, but is permitted an upward movement when the auxiliary flue 9 engages its under surface. The auxiliary flue is preferably made of a non-conducting material, such as fire-clay or asbestos, or of two concentric metal tubes having between them an annular space packed with asbestos or slag-wool.
