Patent GB-1535596-A (GB)
Title: Hydraulic controller
IPC: B62D5/09
Filed: 1976-05-17
Abstract: 1535596 Power steering valves TRW Inc 17 May 1976 [4 June 1975] 20333/76 Heading B7H A valve assembly for supplying hydraulic power steering and implement circuits comprises a first valve having a neutral position in which it supplies the implement circuit and being movable to positions in which it supplies the steering circuit, supply to the implement circuit being progressively reduced, and a second valve for supplying the implement circuit when the first valve is cut off thereof. The valve assembly is arranged in a housing 30 and is connected to a gerotor metering pump 16. The first valve comprises a bore 51 in the housing having annular grooves P, M, X, R, Y, C1, P1, AUX and P2 and an axially slidable spool 15 having grooves 62, 68. An actuating shaft 14 connected to the steering wheel moves the spool through a ball 60 and helical groove connection and is connected by a torsion bar 75 to the shaft 72 connected at 73, 74 to the gerotor pump and spool. With spool 15 in the neutral position fluid entering inlet part 13 passes to groove P and through line 52 to grooves P1, P2 and thence via grooves 67, 68 and AUX to the implement port 22. As the spool moves to the left grooves P, 62 and M and line 53 supply fluid to the gerotor. valve 77 and fluid is returned from the gerotor pump to a central bore 79 of the spool. A radial bore 80 from the bore 79 passes fluid to groove 66 and via groove C1 to one side of a steering cylinder. Return fluid from the other side of the cylinder passes to groove C and via grooves 63, X, 64 and R to return part 21. Movement of the spool to the right allows fluid to flow from groove P via line 52 to groove P, and then via bore 80, the gerotor pump, line 52 and grooves M, 63, and C to the steering gear. Groove C1 connects with groove R for return fluid. Movement of the spool in either direction cuts off the connection between grooves P1, P2 and AUX but if sufficient pressure exists a valve 90 maintains supply to the implement circuit. The valve spool 91 of valve 90 has annular grooves 100, 101 to allow flow to return 21 and, whilst spool 15 is in the neutral position, flow to the auxiliary port 22, and is provided with an end projection 93 so as to form a chamber 94 with its wall 91a when urged to the right by spring 92 in chamber 92a. The chamber 94 connects with groove P2 so that as spool 15 moves to sever supply between P1, P2 and AUX pressure builds up in chamber 94. Fluid passing through a restriction 110 in the spool 91 to chamber 111 opens a relief valve 105 and fluid in chamber 92a is spilled to exhaust through line 115, chamber 111, valve 105, line 107 and port 21, thus allowing the spool 91 to move against spring 92. As the spool moves to the left a land 101a opens the implement port 22 to groove P2 and fluid is supplied to the implement. If the fluid pressure at inlet 13 is insufficient to operate both steering and implement circuits the former is given preference since the metering pump 16 draws fluid from groove P and P2.

Title: Process for the preparation of fast dyeings or prints on cellulose materials
IPC: D06P3/68
Filed: 1962-05-28
Abstract: Materials of natural or regenerated cellulose are coloured by padding them with an aqueous alkaline solution of a coupling component, then dried and subsequently padded or printed with an aqueous acid solution or printing paste or pastes containing a reactive dyestuff and a diazonium compound and finally treating the materials with an aqueous alkaline solution.  The reactive dyestuffs may be water-soluble and preferably contain the b -hydroxyethyl-sulphone-sulphuric acid ester group.  The coupling components are preferably arylamides of aromatic or heterocyclic o-hydroxy-carboxylic acids or of acyl-acetic acids (many are specified).  As diazonium compounds there may be used those which form water-insoluble mono-, dis-or polyazo dyes with the above coupling components including tetrazonium compounds of aromatic diamines.  Since certain coupling components can react with the reactive dyes, a water-soluble aldehyde, e.g. formaldehyde, acetaldehyde or furfural, may be included in the acid solution or printing paste containing the reactive dyestuff to inhibit said reaction.  The alkaline bath for the final treatment may contain sodium hydroxide or carbonate and large quantities of sodium sulphate or chloride; this treatment may be effected by padding, slop-padding or cover-printing with an alkaline salt solution or print paste followed by a passage through air at room or raised temperature, steaming at 100 DEG C., passing over heated drums or passing through alkaline salt baths at 50-100 DEG C.  The diazonium compound and the reactive dyestuff may be applied from the same or separate printing pastes in either sequence, if desired covering each other.  Examples of dyeing and printing fabrics of cotton and regenerated cellulose are given.

Title: Improvements in electric signalling systems, especially applicable to combined telegraph and telephone systems
IPC: H04B3/40
Filed: 1919-08-21
Abstract: 154,303. Western Electric Co., (Western Electric Co.). Aug. 21, 1919. Repeating systems; simultaneous telegraphy and telephony.-A two-way repeater, for a telephone line used also for Morse signalling, is balanced bv artificial lines which are related to the repeater in exactly the same way as the two sections of the transmission line, the inductive shunts which carry the Morse signals being duplicated in the same way as other features. In the arrangement shown in Fig. 1, telephone currents are repeated between the lines 1, 1<1> by repeaters R, R<1>, which may be either of microphonic or thermionic type, while earth-return Morse signals are transmitted over the conductors 3, 3<1> through an inductive shunt 27 and over the conductors 4, 4<1> through an inductive shunt 29. The line 1 and artificial line 22 are each connected to the input circuit of. repeater R' through filter circuits 5, 23, transformers 9, 16, and a transformer 14, while the out-put circuit of repeater R is connected to line 1 and artificial line 22 through a 3-coil transformer 12. The artificial lines 22, 22<1> are connected by inductive shunts 31, 33 corresponding to the shunts 27, 29. The filters 5, 23, which only transmit currents above a certain frequency, consist of series capacities and shunt inductances, the latter earthed at their middle points. A second arrangement is described in which the Morse signals, instead of passing from conductors 3 and 4 to 3<1> and 4<1>, are led aside at the repeater to local Morse instruments, which are connected through equal inductances to the conductors 3. 3<1> &c. and to corresponding points in the artificial lines. The Morse instruments can be disconnected by plug switches, equivalent .impedances being substituted to keep the circuits balanced. Apart from repeater systems, the invention is applicable to terminal telephone sets, when these are connected between the line and a balancing artificial line. Specification 142,115 is referred to.

Title: Improvements in locking means for nuts, bolts and the like
IPC: F16B39/32
Filed: 1922-07-31
Abstract: 206,217. Batchelor, H. July 31, 1922. Locking nuts and bolts. - A nut is locked to a bolt by means of a resilient L- shaped member, one leg of which is held in a seat which is parallel to the axis of the bolt while the other is obliquely directed to engage between two adjacent threads of the bolt. The free movement of the obliquely directed leg is limited by contracting the hole forming the seat for the other leg, which leg may be flattened or widened, so that beyond the limits of oscillation it is subjected to torsional strain. When excessive turning pressure is applied to the nut, the obliquely directed leg of the locking member is carried past the radial position and takes up a locking position in the reverse direction. As shown in Fig. II., the L-shaped member 12 is held and controlled by pressing in the corner of the nut, as at 16. A modification is described in which the arm engaging the bolt thread swings in a recess in the face of the nut. In another modification, Fig. VIII., the axially parallel seat is formed as a groove in a corner of the nut, and the arm accommodated therein is provided with a toe 22 above which the edges 16b of the groove are closed in onto the flattened arm. Fig. XIV., shows a similar locking member 12<c> applied to a bolt or stud B<3>, the arm 13<c> being held in an axial necess 11<c> by forming an indentation 15<c> in the end of the bolt and forcing the metal against. the arm 13<c>.

Filed: 1970-04-30
Abstract: 1310538 Multiplex transmission INTERNATIONAL BUSINESS MACHINES CORP 30 April 1970 [30 April 1969] 20895/70 Heading H4R Data signals are transmitted simultaneously with speech signals in a gap formed in the middle of the speech frequency band. At the receiver a portion of speech is synthesized, using vocoder techniques, to fill the gap in which the data was transmitted. As shown in Fig. 2a, a speech signal from a subscriber's line circuit LC is passed through parallel high and low pass filters HPF1 and LPF1 to remove the band from 1300 to 2300 Hz and replaced by data signals from a transmitter DT. At the receiver the data signals are recovered by a band-pass filter BPF7 and passed to a data receiver DR while the speech bands are recovered using high and low pass filters HPF2 and LPF3 similar to those used at the transmitter. The speech signals are fed direct to a summing unit SA4 and to a non-linear circuit NLC which derives an excitation function signal which is separated out into two synthesis channels by BPF1 and BPF3, passing respectively 1200 to 1900 Hz and 1700 to 2400 Hz, to be modulated by signals derived from an analysis and interpolation of the energy in the bands of the received speech signal adjacent the edges of the gap. BPF5 and BPF6 pass signals in the ranges 900-1300 Hz and 2300 to 2700 Hz, respectively, and the energy in these bands is detected by rectifiers R1 and R2 and low pass filters LPF3 and LPF4. The signals corresponding to the energy levels in these bands are fed to combining networks SA2 and SA3 where they are combined in appropriate proportions to provide interpolations of energy level at frequencies corresponding to the locations of the synthesis channels. The outputs of the networks SA2 and SA3 are fed to the modulators in the synthesis channels to provide signals which fill in the gap in the speech spectrum. In an alternative system, Fig. 3a (not shown), the energy level in the untransmitted band in the original speech is detected at the transmitter and the resulting signal modulates the data signal amplitude. At the receiver the energy level signal is recovered and used to control a synthesis channel in the centre of the untransmitted band and to provide a signal for interpolation with further analysis channels as previously described to provide further synthesis channels at the outer edges of the untransmitted band.
