Data are also given for one example in which the surface Z21 is plane and has the plate 14 cemented thereto, for one in which the elements 14 and 15 are replaced by a plano concave lens having a cemented surface concave to the object . and for one of which such a lens has cemented to it .on the object side a plane parallel plate.

Abstract: 246,288. Ringelenstein, W. C. van, and Riel, T. Dec. 30, 1924. Measuring-devices; air, removing ; relief devices.-In a liquid measuring and delivery system wherein the liquid is drawn from a reservoir 1 by means of a pump 4 and delivered through a meter 8 to a discharge pipe 10, a float-controlled valve is provided at 11 to allow any air or vapour collecting in the supply pipes 2, 5 to pass to the reservoir instead of entering and thereby vitiating the reading of the meter. The valve consists of a seating 25, Fig. 2, held down by an adjustable spring 28 and co-operating with a lift valve 24 controlled by a float 22. If pressure in the system should be excessive the seating can rise to allow liquid to escape by the pipe 12 and thus to the reservoir.

Patent GB-1100863-A (GB)
Title: Process for the manufacture of condensed alkali metal phosphates
IPC: C01B25/42
Filed: 1965-07-22
Abstract: Condensed alkali metal phosphates, e.g Na5P3O10 and Na4P2O7, are produced from a phosphate solution obtained by (a) treating phosphate solution obtained by (a) treating crude phosphates with mineral acid, (b) purifying as desired and (c) adjusting the solution in composition so as to contain alkali metal oxide and P2O5 in a ratio corresponding to that desired to be obtained for the final product, by spray-drying the phosphate solution which contains fluorine in a proportion of 100 to 5000 parts per million, related to P2O5, in a single step in a spray tower at temperatures selected to ensure that gases issuing from the spray tower have a temperature above 300 DEG C. and contain, per kg. of issuing gas (including water vapour), moisture in a proportion of 150-400 grams of water, the said phosphate solution containing dissolved alkali phosphate in a proportion of 40-70% by weight of the solution.  Prior to spraying the phosphate solutions may be mixed with any desired proportion of a phosphoric acid or phosphate solution which has been prepared from phosphorus (e.g. by elctrothermal means). In examples steam or compressed air is passed through the spray tower along with the phosphate solution.

Title: Improvements in or relating to radio horns
IPC: H01Q19/08
Filed: 1946-03-19
Abstract: 629,151. Aerials. RUST, N. M., and RAMSAY, J. F. March 19, 1946, No. 31281/48. Divided out of 629,107. [Class 40 (vii)] In a radio horn, the velocity of propagation is differently modified over different paths from apex to aperture so as to compensate to a desired degree for the effects of the different lengths of the paths on the phase distribution across the aperture, the modification being obtained by varying the rate of flaring at different portions of the paths. As shown, a horn has normal wave-guide dimensions at. the apex C and has an aperture 10 which is wide in the direction of the electric vector. To compensate for the greater length of the outer paths from the apex to the aperture, the dimensions of the outer paths are kept down to the apex dimensions until a point 0 where flaring commences. Other paths commence flaring at progressively earlier stages, the central path flaring at C. This produces a plane wave at the aperture. In a modification (Fig. 2, not shown), the constricting effect on the outer paths is carried out by means of internal walls in the horn. For a horn which is wide in the E-direction but very narrow in the H-direction the correction may be carried out by delayed flaring down of the H dimension. The invention may be used in conjunction with the velocity modifying plates described in Specification 629,107. Also, plates at rightangles to the electric vectors may be used to reduce refraction effects.

Filed: 1974-07-16
Abstract: 1440724 Ear implants J M FREDRICKSON 16 July 1974 31447/74 Heading A5R [Also in Division H4] An implantable hearing aid comprises a permanent magnet 12 (Fig. 4) which, in use, is rigidly secured to the stirrup bone 13 (stapes) of the ear and a coil 14 located coaxially around or above the magnet 12 in close provimity. When the coil 14 is energised by audio frequency signals the stirrup bone 13 is moved in the same manner as it would be by the anvil bone (incus) to cause vibration of the inner ear fluids. The coil 14 is permanently fixed by a support 15 held by non-tissue toxic cement 40 to bone within the mastoid bowl. Connections 16 from the coil 14 are preferably taken out of the ear through a hole drilled in the mastoid tip of the temporal bone (i.e. behind the outer ear). This hole receives the threads 36 (Fig. 10) of an externally threaded socket 35. The connections 16 lead to two female terminals 34 in a receptacle 11. These terminals 34 receive three pins 33 of a housing 10 enclosing a microphone, amplifier and battery. Two of the pins 33 are connected to the amplifier output while the third pin provides stability. A cap 37, which may have its top end closed (not shown) e.g. when swimming, is threaded on to the top of the socket 35 to hold housing 10 and receptacle 11 in position. Housing 10, receptacle 11 and socket 35 are of non tissue toxic material such as P.T.F.E. Cap 37 is of this material or of stainless steel. The microphone is a condenser type and the amplifier is preferably a logarithmic amplifier. Terminals 33 and 34 are gold plated. The magnet may be encased in and attached to the stirrup 13 by a holder of P.T.F.E. Alternatively magnet 12 is secured to stirrup 13 by non tissue toxic cement such as "SILASTIC" (Trade Mark) or "CRANIOPLAST" (Trade Mark), in which case it is either non tissue toxic, e.g. of "VITULIUM" (Trade Mark) or is encapsulated in non tissue toxic material. Alternatively the holder 17 is mechanically secured to the stirrup 13 without cement, the springiness of the holder providing the connection or the holder is crimped in position. The coil 14 is of copper wire embedded in "SILASTIC" (Trade Mark). In order to implant components 12, 15 and 17 a mastoidectomy is performed, the facial triangle bone is removed and the anvil bone is removed. The holder 15 is of silver wire flattened at the coil end. The microphone, amplifier and battery, individually or in total, may be located elsewhere than behind the ear. An implanted radio receiver may feed the coil, there being an external radio transmitter and microphone.

Application of a suitable bias above a threshold level between ohmic electrodes 15, 16 produces pulse oscillations due to avalanche breakdown in the v region 13, the frequency of oscillation being determined by the period for which avalanche-generated holes in the region 13 are trapped at the deep level Fe acceptor centres. The mechanism whereby oscillations occur is discussed in the Specification.
