Title: Feeler for examination or treatment of solid bodies by pressure waves
IPC: B06B1/06
Filed: 1948-12-07
Abstract: 665,744. Supersonic inspection devices. ATELIERS DE CONSTRUCTIONS ELECTRIQUES DE CHARLEROI. Dec. 7, 1948. [Dec. 19, 1947] No. 31600/48. Class 118 (ii). [Also in Group XXXIX] Relates to means for coupling an electro-mechanical transmitting or receiving transducer, e.g. a piezo-electric crystal, to the rough surface of a solid undergoing test or treatment by pressure waves of the type disclosed in Specification 613,239 in which the transmitting or receiving surface of the transducer is in contact with an enclosed body of liquid under pressure, a portion of the fluid-containing wall comprising a flexible elastic membrane, e.g. sheet rubber, which assumes the shape of the surface when brought into contact therewith. The liquid must be a good conductor of pressure waves and the contact with the surface is improved if the membrane is permeable by the liquid so that a liquid film forms on the outside of the membrane. The form of coupling described in the specification referred to is not suited to movement over the surface and this is achieved in the present invention by enclosing the liquid 13 in a barrel-shaped container comprising end plates 7 and a side wall 12. formed by the membrane, the container being rotatably mounted on a hollow axial shaft 1 by means of bearings 8 and fluid-tight packings 10, the end plates may be rigidly interconnected. Four piezo-electric crystal transducers 2 are insulatedly mounted in recesses on the outside of the shaft and the electrodes 3 and 4 of the crystals are connected to apparatus outside the container by leads 5 and 6 passing through the hollow shaft. The liquid is supplied to the container through the hollow shaft and the hole 14 in the shaft. In operation the container is rolled over the surface so that the membrane makes intimate contact therewith, the shaft being held so that the free surfaces of the crystals are directed towards the surface. The Specification as open to inspection under Sect. 91 states that the end plates may be rigidly connected to the shaft 1 which is then rotatably mounted in a support external to the container the transducers being rotatably mounted on the shaft. This subject-matter does not appear in the Specification as accepted.

Title: Improvements relating to the manufacture of alcohol
IPC: C07C29/06
Filed: 1930-10-21
Abstract: In the preparation of alcohol from ethylene by absorption in sulphuric acid of less than 80 per cent strength under elevated temperature and pressure, as described in Specification 360,492, the absorption is carried out in the presence of chemically inert solid or liquid materials capable of increasing the surface of inter-contact between the reacting substances.  The solid material may be pumice, procelain chips, finely divided carbon, silica gel, and may be packed in a tower down which the acid passes while the ethylene ascends.  The liquid material may be a refined mineral oil which may be emulsified.  The simultaneous use of both solid and liquid surface extenders is particularly advantageous.  The surface extender may be mixed with the acid, and the ethylene passed through in countercurrent, or one extender may be mixed with the acid and another contained in a tower down which the acid flows.  The preferred temperatures and pressures are below 200 DEG  C. and 250 atmospheres respectively. Ethylene or gas mixtures rich in ethylene, e.g. ethylene fractions from the gases obtained in cracking hydrocarbon oils, may be used. Examples of the process are given.

Filed: 1952-12-18
Abstract: 758,250. Ice-making. FRENCH, A.A. and McGREGOR, A. N. Nov. 23, 1953 [Dec. 18, 1952], No. 32113/52. Class 29.  In apparatus for making ice-blocks in moulds 10 similar to that described in Specification 699,404, the blocks are thawed off in series by water circulated through a mould jacket 14 by a pump (not shown) from a tank 38 beneath the moulds, the water being heated during the ice-making phase by a coil 45 through which flows the compressed refrigerant gas. When the pump is started for thawing off, a valve supplying refrigerant to the evaporator 15 is automatically closed. The pump supplies water through a pipe 30 to the part of the jacket 14 adjacent the right hand mould 10 and, when this part is filled, the water passes through an aperture 35 in a partition 24 to fill the middle part of the jacket and then through an aperture 36 in a partition 23 to fill the lefthand part of the jacket. Excess water flows back to tank 38 through an aperture 37. The moulds are thus thawed off in series. When the pump stops, the water leaves the jacket through pipe 30 and apertures 32, 31 which are of less area than the apertures 35, 36. The partitions 23, 24 may be of inverted V-shape to reduce the effective volume of the jacket.

The means 18 is in the form of a baffle which encloses a space 26 through which oil, fed through apertures 25 in the housing, passes and is directed by the baffle onto the surface of the web 20. The cavity inlet 33 is defined between the lower end 19 of the baffle and the gear surface. The means 21 is a second baffle which is secured to the toothed portion 15 of the gear and which has an inwardly directed lip portion 22 the free edge 24 of which defines the cavity outlet 34 with the baffle 18. In a modification, Fig. 3 (not shown), the gear is rotated about a horizontal axis and the oil issuing from the apertures (25) in the housing, instead of flowing through a space such as that shown at 26 in Fig. 1, passes through a series of annularly arranged pipes (29) secured at one end to the housing and having their free ends spaced from the web 20 and surrounded by an annular flange which is parallel to and spaced from that surface and defines therewith the inlet 33 to the cavity 23.

Abstract: 466,415. Valve circuits for wireless reception. ROBINSON, J. Nov. 22, 1935, No. 32397. [Class 40 (v)] In a superheterodyne receiver a portion of the beat frequency output from the frequency changer is applied directly or indirectly to the oscillator to change the amplitude of the signals applied to the frequency-changer. The Figure shows a superheterodyne receiver in which intermediate frequency energy is passed through a selective circuit 38, and phase control 41 to a control valve 42, which injects intermediate frequency energy to a tuned circuit 44 in series in the oscillator grid circuit and is controlled by automatic volume control potentials over lead 45. Intermediate frequency energy may be taken from the output instead of the input to the intermediate frequency amplifier, Fig. 2 (not shown). A separate mixer or detector may be associated with the oscillator to effect the re-conversion of the intermediate frequency to signal frequency, Fig. 3 (not shown), and a filter may be interposed in the feed-back circuit to suppress the intermediate frequency. A separate oscillator may be used in addition to a separate detector for producing signal frequency from the intermediate frequency. Specification 337,049, [Class 40 (v)], is referred to.

The piston is connected in a detachable manner as by a thread 20 with a rod 7 operated by an outside handle 16. The piston - rod is continued by a rod 8 which, when the rod 7 is disconnected from the piston, is passed into a passage 4 in the brush head so as to close the passage and prevent caking of paste &c. The passage 4 communicates with an outlet 6 surrounded by a circular or other setting of bristles in the middle of the brush. The reservoir can be filled by a flexible tube 14, Fig. 2, of paste. The piston 5 has projections 19, Fig. 1, which engage other projections 18 on the end of the reservoir so that it can be held while the rod 7 is disengaged from the piston. The brush head is detachable from the reservoir and may have a detachable cover. The device may be used with tooth or shaving brushes.
