Class 122(1) [Also in Group'XXXII] A shock absorber piston 11 has an annular oil sealing chamber 15 between it and the cylinder wall 10 supplied through an inlet 60 and a relatively movable .free piston 20 presenting one face to a chamber 12 and having the opposite face open to the chamber 15; the inlet 60 being supplied with pressure fluid e.g., oil from an extraneous reservoir 65 and the chamber 12 being charged with compressible fluid e.g., air through a non-return valve 24.

The return stroke is damped by oil pressure in a chamber 61. In a modification the chamber 15 is supplied with oil from a source separate to the chamber 61 and reservoir 65, and in a further modification including said separate supply the pressure responsive member comprises a pair of spaced rings between the piston and cylinder. Compressed air instead of oil may be supplied to the chamber 61.

Title: Improvements in or relating to photographic tanning developer
Inventor: WILLEMS JOZEF FRANS
IPC: G03C5/315
Filed: 1958-09-04
Abstract: 862,615. Photographic developers. GEVAERT PHOTO-PRODUCTEN N.V. Sept. 4, 1958 [Sept. 5, 1957], No. 28424/58. Class 98(2) The rate of aerial oxidation of a tanning developer is retarded by the presence of an ascorbic acid borate or a water-soluble salt of an ascorbic acid borate. Since the borate competes little with the tanning developer in developing the silver halide, higher concentration of ascorbic acid borate can be used, than can ascorbic acid, without producing insufficient tanning of the gelatine. The alkali salt of ascorbic acid' borate is obtained by heating boric and ascorbic acids in alkaline aqueous solution. In the examples a developer composition includes sodium or potassium ascorbic acid borate, sodium carbonate or potassium hydroxide, pyrocatechol or pyrogallol and a calcium ion sequestering agent. The developer may be compounded as a powder. Specification 560,731 is referred to.

Title: Improvements relating to electrical musical instruments
IPC: G10H5/10
Filed: 1932-10-12
Abstract: 408,645. Electrical musical instruments. ALLGEMEINE ELEKTRICITATSGES., 2, Friedrich Karl-Ufer, Berlin. Oct. 12, 1932, No. 28488. Convention date, Oct. 12, 1931. [Class 88 (ii).] In electrical musical instruments, particularly of the kind employing a grid-controlled thermionic tube with a discharge tube such as a neon lamp in the anode circuit, and wherein the frequency of the oscillatory circuit is controlled by means of a potential obtained by manually tapping a resistance, this resistance is included in a network of resistances which is such that above a certain frequency the desired exponential increase of the frequency is produced by a linear change in a resistance of the network and thus equal musical intervals (geometrical) are associated with equal playing intervals (arithmetical) on the manual resistance. In Fig. 2, the frequency-controlling potential f is obtained from the network of resistances R1, R2, R3 with the manual resistance wire M, the lower limit of voltage obtainable depending on R3 and the upper on R2, R1 being a high resistance. Resistance R2 is made adjustable for correcting the characteristic of a tube or to account for its aging, or to suit different tubes. In order to avoid interference frequencies that may occur even when not playing, a very high resistance may be connected in parallel with the neon lamp, or the lamp may be exposed to light, or oxides of the rare earths may be introduced therein.

Title: Equalizer
IPC: H03H19/00
Filed: 1977-07-07
Abstract: 1536113 Setting transversal equalizers INTERNATIONAL BUSINESS MACHINES CORP 7 July 1977 [8 July 1976] 28504/77 Heading H4R In an arrangement for determining the initial values of the multiplier coefficients of a transversal equalizer in a synchronous data transmission system, a reference signal, comprising a periodic sequence of elements, is transmitted over the transmission channel and the signal received from the channel is modulated by a time domain window the Fourier transform of which has a relatively flat central peak and low values in the vicinity of those frequencies which are multiples of the inverse of the period of the transmitted sequence, the discrete Fourier transform of the resulting signal is calculated and divided into the discrete Fourier transform of the transmitted sequence in order to provide a signal whose inverse Fourier transform provides the values of the coefficients of the equalizer. Using the particular time domain window makes the derivation of coefficients relatively insensitive to frequency shift in the channel. As described, the system uses double sideband quadrature carrier modulation and the transmitted reference, or test, signal is a CAZAC periodic pseudo random sequence having a periodic autocorrelation function only the first term of which is non zero and all the complex numbers in the sequence having a constant amplitude. At the receiver the received signal is split into in-phase and quadrature components by a Hilbert transformer and, during setting up, applied via lines 16 and 17, Fig. 4, to modulators 21, 22 where the signal is modulated by the time domain window which is preferably a triangular window of duration twice that of the transmitted sequence and of maximum amplitude unity. The discrete Fourier transform (DFT) is derived at 24 according to the expression to provide real and imaginary components, i.e, amplitude and phase, of the weighted spectrum. at K sampling points. These components are multiplied in 27 by stored DFT of the transmitted sequence Z K  to provide the quantity G K , while multiplier 26 produces W K <SP>2</SP>. Unit 28 provides the quantity 1/W K  from the value W K  and this quantity multiplies G K  in multipliers 29 and 30 to provide the quantity F K  = G K /W K <SP>2</SP>. The quantity F K  is applied to an inverse DFT generator 32 to provide the coefficients to set into the multipliers of the transversal equalizer.

Moulding celluloid.-Sheets, slabs, or moulded articles are produced from celluloid and like materials by welding together, under the action of heat and pressure, thin sheets from which the greater part of the volatile solvent has been removed. Any solvent remaining in the moulded articles is removed by drying for a short time at a high temperature. The thin sheets may be cut from a slab prepared in the usual manner and are, for example, half a millimeter in thickness.

IPC: F02M7/06
Filed: 1922-10-23
Abstract: 187,630. Lange, P. Oct. 22, 1921, [Convention date]. Spray carburettors.-Excessive flow of fuel is prevented by feeding the main nozzle g and the nozzle h supplying the slow-running passage s through an orifice e which is too small to feed both nozzles simultaneously at full capacity. The orifice h<2> of the nozzle h communicates through openings h<3> with a well k into which the slowrunning passage s opens. The nozzle h is also provided adjacent the top of the well with a passage l communicating by a conduit m with a second passage n regulated by a screw o. The passage n and an aligned passage p fitted with a regulating-screw t place the float chamber a in communication with the mixing-chamber below the throttle j, the suction transmitted through the passages further retarding the fuel flow. During slow-running, the fuel in the passage s is mixed with air drawn in through the passages p, n, m, and during acceleration the fuel in the well k passes through the orifice h<2> and augments the supply to the main nozzle.
