Title: Improvements in record card controlled recording machines
Filed: 1953-11-27
Abstract: 738,956. Statistical apparatus. MAUL, M. Nov. 27, 1953 [Dec. 6, 1952], No. 33050/53. Class 106 (1). A record-card controlled machine having a group change control device is arranged so that the group change control device actuates an arranging device located between the sensing means and the recording means for the duration of the analysis of the last card of a group. The plug board is arranged so that each of the card columns or analysing brushes b<SP>3</SP> is associated with a plug socket p and s for controlling the printing means. The cards are fed in known manner by rollers past analysing brushes bl, b<SP>2</SP>, b<SP>3</SP>, from bottom to top in Fig. 3, the brushes bl, b<SP>2</SP> serving for the group control and the brushes b<SP>3</SP> for the transfer of the data to the printing mechanism. If the two cards under the brushes b<SP>1</SP>, b<SP>2</SP> have the same group number current will flow through brush b<SP>1</SP> contact u<SP>1</SP>, g<SP>I</SP>, through relay G contact g<SP>II</SP> and the brush b<SP>2</SP> to positive line. If all group relays G have responded all similar contacts will be open and current to relay H remains uninterrupted when cam contact n<SP>2</SP> closes. If, however, a group relay has not responded, i.e. there is a change of group number, one of the contacts g<SP>III</SP> will remain closed and the relay H responds, closing its contact h<SP>I</SP> and switching the contacts h<SP>II</SP>. By means of contact h<SP>1</SP> the relay H establishes a holding circuit through the cam contacts n<SP>1</SP> so that it remains energized when the cam contact n2 opens. The contacts h<SP>II</SP> switch the analysing brushes b<SP>3</SP> from the plug sockets p to the plug sockets s. The relay H will now remain energized during the next card cycle. When the next cycle has finished the contacts n<SP>1</SP> open for a short time, interrupting the holding circuit through the relay H and causing the latter to de-energize. In the meantime the two subsequent cards have been analysed by the brushes b<SP>1</SP>, b<SP>2</SP> and it has been determined whether the two group numbers are alike, in which case the contacts gIn have been opened and the circuit to relay H remains interrupted even if cam contact 22 closes as described above. To render the re-arrangement device ineffective, i.e. for single item cards, the contact u<SP>1</SP> is shifted and the contact u<SP>II</SP> is opened manually by means of a key, the brushes b<SP>1</SP> are disconnected from the group control by means of the contact u<SP>1</SP> and the brushes b<SP>3</SP> are connected thereto. The contact u<SP>II</SP> interrupts the current to the relay H so that it cannot be energized and no re-arrangement can take place.

IPC: G01P5/16
Filed: 1957-10-23
Abstract: 839,405. Electrical measuring systems. SPERRY GYROSCOPE CO. Ltd. Oct. 10, 1958 [Oct. 23, 1957], No. 33127/57. Class 40 (1). Airspeed measuring apparatus comprises a pitot head mounted at a fixed radius from an axis to rotate continuously about the axis and means to determine the airspeed in a predetermined direction by determining the pitot pressure difference when the pitot head axis is in the two positions substantially parallel to the predetermined direction. Fig. 1 shows a pitot tube 1 connected to a sealed chamber 5 which is separated from a second sealed chamber 6 by a flexible diaphragm 7. The second chamber 6 is connected by a tube 4 to the static air pressure. The diaphragm 7 carries a ferromagnetic armature 9 positioned adjacent the pole pieces of the coils 8 so that when the coils 8 are connected in bridge circuit as in Fig. 3 and bed with 400 c/s. alternating voltage from source 11 any difference in pressure in chambers 5, 6 results in a displacement of the armature 9 and an unbalance of the bridge. The unbalance voltage is amplified by a transistor circuit 12 and rectified at 21. The rectified output is fed to the rotor of a distributing switch 24 synchronized with the rotor of the helicopter. The pitot head 1 is attached to one of the helicopter blades 2. When the blade is in positions 15, 17 capacitors 32 are respectively charged to a voltage dependent on the effective airspeed in these positions. The difference in these voltages is fed via resistor 33 to one coil 34 of a ratiometer 42 calibrated in forward airspeed. The voltages in positions 16, 18 are used to charge capacitor 38 so that a voltage dependent on the sum of the voltages in these positions is fed via resistor 39 to the other coil 41 of the ratiometer. It is shown that the quotient of these voltages is proportional to forward airspeed. The coils of a further ratiometer calibrated in sideways airspeed may be respectively fed with the sum and difference of the voltages dependent on the airspeed in positions 16, 18.

A plurality of saturable magnetic elements 1a-1d, Fig. 1, having the same dimensions and formed of material with a rectangular hysteresis loop each have a driving coil 2a-2d with a different number of turns, the application of a driving current I of increasing amplitude causing each element to reverse its magnetic state in turn so that a train of pulses d-a, Fig. 3, is produced in a common read-out coil 5, while a separate pulse is produced sequentially in each of further and separate read-out coils 4a-4d associated with the elements. The elements may comprise separate toroidal cores or apertures in a common structure. The interval between successive pulses depends on the difference in the number of driving coil turns on each element, if this difference is slight the pulses overlap and a single output pulse of prolonged duration is obtained in coil 5 as shown in Fig. 4b. In Fig. 5, a further read-out winding 6 is provided which is loaded by a resistor 7 so as to extend the duration of changeover of each element in turn. A modification is to have the same number of turns in each driving coil and a different number of turns in each section of the loaded read-out winding 6 associated with respective elements. It is stated that reversal of state of the cores may be further influenced by relative dimensions and material of each core.

Filed: 1976-08-12
Abstract: Water-soluble azo dyes which in the form of the free acid conform to the formula I <IMAGE> where R<4> is hydrogen, optionally substituted alkyl or arylsulphonyl and the other substituents are as defined in Claim 1, are obtained by reacting appropriate diazotised amines with coupling components of the formula C6H3(R5)(R6)(OH) and then optionally alkylating or arylsulphonating. The new dyes are suitable for dyeing and printing natural and synthetic amido-containing fibre materials, for example those comprising wool, silk and polyamide, such as polyepsilon -caprolactam or the reaction product of hexamethylenediamine with adipic acid. The dyeings obtained, in particular those on polyamide materials, are notable for good fastness properties, in particular for good wet fastness properties and good light fastness properties. Similarly, the neutral-dyeing capacity and the compatibility with other suitable dyes for this material is in general good. The dyes of the formula (I) are normally used for dyeing either in the form of the free acid or in the form of an alkali metal or ammonium salt.

Title: Improvements relating to bituminous materials
IPC: C10C3/00
Filed: 1936-12-11
Abstract: Self-emulsifiable asphalts are obtained by distilling an asphalt-containing petroleum crude oil up to 400 DEG  F. and then mixing the residual oil under suitable pressure with a low-boiling solvent, preferably ethane, propane or butane, at a temperature of about 250 DEG  F. whereby the asphalt is precipitated and separated from the oil and solvent.  Excess solvent can be stripped with natural gas or steam up to 400 DEG  F.  If desired, the hydrocarbon solvent can be mixed with phenol, cresol, aniline or furfurol. The softening points of the asphalts may be varied by variation of the solvent, the amount used and the temperature of precipitation. The products may be used to reduce the amount of added emulsifying agent necessary for slowsetting emulsions or may be mixed with other asphalts, preferably not self-emulsifiable, to produce quick-setting emulsions.  For example, (1) 20 per cent of solvent-precipitated asphalt obtained by reducing a Venezuela crude oil up to 400 DEG  F. is blended with 80 per cent of asphalt fire-reduced at 620-650 DEG F. 55 Pts. of this mixture was heated and added to 44,8 pts. hot water containing 0,13 pts. caustic soda and 0,07 pts. bentonite.  (2) A slower-breaking emulsion was obtained by blending 60 per cent of solvent precipitated asphalt with 40 per cent of asphalt reduced up to 650 DEG  F. 52 Pts. of this mixture were added to a solution of 0,15 pts. caustic soda in 47,85 pts. water.  Less than 1 part of soap may be added as a stabilizer.
