Patent GB-109475-A (GB)
IPC: B21J7/12
Abstract: 109,475. Morris, A. W. Sept. 12, 1916 Casting-machines; castings, extracting; moulds. - Casting-machines of the compression-after-charging type, particularly adapted for carrying out the process described in Specification 109,476, are so controlled by a pyrometer that when the metal in the mould has cooled to a predetermined temperature, a one-revolution clutch device is actuated to move the mould under the press cam, skim off the dross, apply pressure, eject the casting, and return the mould to the filling position. The shafts 9, 23, Fig. 1, are geared to the mainshaft 50. The press head 2 is actuated by an eccentric and a toggle. The mould 14 is moved by cam linkage 19 and carries a cam 37 which raises the frame 38 to lift the pyrometer 39 clear of the mould. As the mould moves forward a scoop-like skimmer 45, Fig. 3, is depressed by a spring 43. The hinge 46 is constructed to yield when the mould returns. The ejector 26, Fig. 1, is located by a collar 27 and is operated by a cam lever 28. As the indicator 76, Fig. 7, reaches a predetermined temperature, contact is made at 80 and a relay 82 closes the circuit of a solenoid 67, thus tripping a detent 62, Fig. 4. A spring 68 then rocks a three armed lever 61 to rotate a cam ring 58 in a one-revolution clutch 53 and release dogs 54 for engagement with teeth 52, Fig. 5, on the continuously rotating element. After one revolution, a tappet 70, Fig. 4, returns the lever 61 with-drawing the dogs, and the detent 62 having been returned, the parts are again locked in the initial position. The return of the detent 62 is effected as soon as the indicator leaves the contact 80. In order that the clutch may not be operated as the indicator rises past the contact 80 on the introduction of a fresh charge, a contact 91, Fig. 7, is provided. When the indicator reaches this, a solenoid 94 is energized to raise a latch 96 and permit a spring 97 to open the circuit of the solenoid 67 at 85. The switch 86 is reset by a solenoid 101 energized when the indicator reaches a contact 98.

The plate 8 is connected to a lug 22 on the carrier by toggle levers and the pin 25 is secured to a link 31 operated by the handle. The fixed contacts are supported by a panel 13 which also carries the hold-on magnet 36, the magnet armature 37 being hooked to engage the pin 38 in the running position. When the handle is moved to raise the toggle pin 25, the weight of the carrier and the action of the frictional roller 20<a> on the spring plate 21 keep the carrier down and the contact fingers 1 - - 5 therefore rotate to engage the contacts 1<a> - - 5<a> to connect the motor M to the line through the transformer windings 40, 41. Further rotary movement of the toggle levers is stopped by a pin 32 so that, as the handle continues to move, the carrier and contact fingers are lifted bodily until the fingers 3, 4, 5 engage the contacts 3<b>, 4b, 5b to connect the motor directly to the line.

Title: Radio navigation system
IPC: G01S1/30
Filed: 1956-04-12
Abstract: 837,913. Electric analogue calculating. SEISMOGRAPH SERVICE CORPORATION. April 12, 1956 [May 26, 1955], No. 11199/56. Class 37. [Also in Group XL (c)] A radio navigation system (see Group XL (c)) producing two A.C. voltages of amplitude proportional respectively to the perpendicular distances E R L R  and E G L G , Fig. 2 of a fixed reference point T from two position lines 150 and 75 which intersect at the position P of a moving craft and are relatively inclined at an angle #, comprises means for computing the distance r and bearing C of T from P. It is shown that the quantities c and r are defined by (E R L R  + EaLa cos #) sin C - E G L G  sin # cos C = e1 = 0 and r sin # = e2, where e2 = (E R L R  + E G L G  cos #) cos C + E G L G  sin # sin C. As shown in Fig. 5 the voltages E R L R  and E G L G  are produced by potentiometers 99 and 97, the output E G L G  from potentiometer 97 being applied to ganged sine and cosine potentiometers 102, 103 (adjusted manually by hand wheel 106) to give outputs E G L G  sin # and E G L G  cos #. The output E G L G  sin α is applied to the stator 108a of a resolver 108 and the output E G L G  cos B is added to E R L R  in an amplifier 109 and applied to the other stator 108b. The output from the rotor coil 108c is thus equal to e1 as defined above and this is applied to an electromechanical servo 111, 112, 113 which rotates the rotor until e1 = 0. When this obtains the angular position of the rotor shaft 124 is equal to the required bearing C and the output from the other rotor coil 108d is equal to e2. This output is applied to a differential amplifier 115 together with a voltage y sin # from potentiometers 116, 104, the potentiometer 116 being adjusted by a motor 118 energized by the amplifier 118 to establish the condition e2 = y sin; when this obtains y = r and the magnitude of y is displayed on the range indicator. The true bearing A = C + E and relative bearing G = A - F, Fig. 3 (not shown), may be indicated at 123 and 132 by manually setting in the bearing E of the position line 75 and automatically setting in the craft heading F as derived from a heading gyro 131 and compass 127.

Abstract: 1,235,571. Ciphering machine. TRANSVERTEX A.B. 5 March, 1969, No. 11766/69 Heading G5X. A ciphering machine for ciphering text in clear produced in binary form by superimposing every text in clear character signal kl with a variable ciphering signal ov, comprises a number of electric devices, stepped in parallel, with cyclic operations viz shift registers Sa-Sd said devices being formed by rows of mutually different numbers of bi-stable flip flops a 1 -a 1 , b 1 -b 12  etc., the initial states of which are set so that the states of the flip flops stepped in parallel in every column k 1 -k 10  in the different shift registers together define a ciphering character which changes its nature as soon as a register has completed a cycle, and comprises an arrangement whereby signals corresponding to the flip flop states of one or more automatically selectable flip flop columns are transferred to an adding device SA for forming said ciphering signal to be superimposed to the text in clear. As shown, the arrangement for automatically selecting at least one certain flip flop column comprises a number of character selectors T 1 -T 4 , each with a number of inlets i1-i4, corresponding to the number of flip flop rows the inlets being connected in parallel to corresponding outlets L 1 -L 4  on the flip flops in a reference column viz k1 and each with its outlet U 1 -U 4  being connected to an inlet of two AND-gates O 1 -O 8 , the second inlet of each gate being connected to an outlet on an adding circuit A 1 -A 8 . The adding circuit inlets are connected with outlets on the flip flops in the corresponding column whereby for a certain character in said reference column only one character selector gives an output signal to its AND-gate for effecting a signal from the adding circuits representing said ciphered signal. Every character selector itself comprises a system of AND- gates (Figs. 2 and 3, not shown). A switch V makes possible shifting of the connections between said flip flop columns and the character selectors.
