Title: Improvements in locks for the gates of railway level crossings, and the like
IPC: B61L29/02
Filed: 1925-11-13
Abstract: 265,694. Fraser, J. H., and British Power Railway Signal Co., Ltd. Nov. 13, 1925. Electrically operated or controlled fastenings; sliding bolts. - Locking mechanism particularly adapted for railway crossing-gates comprises a hand-operated bolt which is shot into the lock casing and then turned and is automatically locked by a catch controlled by an electromagnet that is required to be energized before the bolt may be retracted and the gate opened. The catch is carried by the armature of the electromagnet, and the circuit of the magnet is controlled by a contact closed by a lever that is associated with the signals for the passage of the train through the gate. The member 7 carrying the armature is pivoted at 8 and has a catch 9 for engaging with a shoulder 10 in the periphery of a rotatable disc 11. The disc is carried by a spindle 12 formed at each end with an axial hole and a radial slot for engagement with the end 30 and lug 28 of the bolt 25 when the bolt is moved by a handle 26 into engagement with the lock casing. By then turning the bolt in a clockwise direction, Fig. 2, the lug 29 moves in the slot in a plate of the casing, and by means of the lug 28 the disc 11 is moved to cause the catch 9 to fall behind the shoulder 10. In this position of the member 7, a conducting strip 31 contacts with a pair of spring contact members 32. Fig. 7 shows the diagram of circuits for the gate lock and for the control lever in the signal box. When the gate is to be opened, the gateman advises the signalman by telephone or bell-signal and then places his control switch 45 into the dotted line position. The signalman actuates the king-lever and the catch 41 drops and is engaged and locked by the member 42. The contacts 43 are also closed, and on the gateman actuating his push-button 39 the circuit of the magnet 5 is completed, the catch 9 lifted, and the contacts 32 broken. The bolt 25, is then free to be withdrawn and the gate opened. On the gate being closed and bolted, the circuit of the magnet 40 is closed at the contacts 32, the magnet 5 being de-energized as the switch 38 is normally open, and the gateman actuates his switch 45 to the full-line position. The signalman moves his switch 44 to energize the magnet 40 and lift the catch 41, and the king-lever is freed for permitting rail traffic to be resumed. When the catch 9 engages behind the shoulder 10 of the locking mechanism, a spring 19 engages in a notch 17. A hand-operated release for use in emergencies may be provided for the lock.

Title: Improvements in or relating to record-card-controlled statistical machines
Filed: 1925-11-18
Abstract: 243,362. British Tabulating Machine Co., Ltd., (Assignees of Bryce, J. W.). Nov. 22, 1924, [Convention date]. Statistical sorting machines.- In a sorting machine for Peirce Code cards there is a card-reading device at each sorting-box consisting of one or two brushes 104, each device being arranged according to a particular one of the ten numbers of the code as shown in Fig. 5. For any one reading device the brushes are connected in parallel, Figs. 7, 7<a>, to one winding of a magnet 107 operating the deflector 108. This magnet has two windings and resistances are arranged in these circuits so that the windings are only energized equally to allow the deflector to rise when all the brushes of the particular reading device make correct contact simultaneously. The card-feeding rollers and the card-feed picker-blade mechanism are as described in Specification 242,654. By traversing the brush holder 101 across the machine each reading device may co-operate with any desired column. The brush-operated magnets 107, Fig. 3, have each two opposed windings which when unbalanced attract the armature 118 pivoted at 120 and maintain raised an arm 119 latching the deflector arm 110. When a correctly-perforated card is read, the windings are energized equally, the armature is raised by spring 122 and the deflector is raised by spring 111 to divert the card. The numerals 10 and 20 on Figs. 7, 7<a> represent' the units of current allowed to pass by each resistance, so that if all the parallel circuits are not made when the card is in the correct reading position and the cam contacts 126 give a momentary closure of the main circuit, one winding of the magnet is energized more than the other and the armature is maintained lowered. A special arrangement of two brushes is provided for the " 5 " sorting deflector in order that it may take its correct place in the sequence 0 - - 9 without operating for " 1 " and " 3 " cards. Once per card-cycle, a bar 113 and pins 117 return all unlatched deflectors. In addition to sorting machines, the invention is applicable to other record-card-controlled machines. The Specification as open to inspection under Sect. 91 (3) (a) included switches 130 for cutting out any desired reading device. This subjectmatter does not appear in the Specification as accepted.

Title: Improvements in grain oriented ingots
IPC: B22D27/04
Filed: 1957-09-17
Abstract: <PICT:0822533/III/1> <PICT:0822533/III/2> Grain-oriented ingots are cast in a mould cavity 18 (Fig. 1) formed in rammed pulverulent moulding material 13, and lined with a compacted mass of pulverulent material 16 which emits heat by an exothermic reaction when contacted with the molten metal, the ingot being formed by removing heat through a base-plate 10 to coolant flowing through a heat-exchanger 11.  The material 16 is thicker towards the top to ensure that solidification of the melt progresses from the bottom to the top to obtain an ingot composed of elongated columnar grains.  The material 16 may be a mixture of crushed fired clay, powdered aliminium, iron oxide and sodium nitrate.  When the ingot is grown on a seed slab 25 (Fig. 4) at the bottom of the mould, the slab 25 is insulated from plate 10 by being supported on spacing elements 26, so that the surface of the seed slab may melt before solidification begins.  A limited flow of molten metal passes through a space 28 and fills the insulating space under the slab 25 and solidifies therein, so that heat is then extracted from the melt in the mould by the heat exchanger.

One line delay line 2 and diode switching device 4 controlled by flipflop 9 combine to provide one output at terminal 6 having one R-Y modulation axis and another output at terminal 13 having the opposite R-Y modulation axis. The output from terminal 6 is supplied to a burst gate 10, continuous wave generator 11 and oscillator 12 to produce a sub-carrier frequency reference signal in phase with the bursts in the signal from terminal 6. The output from terminal 13 is fed to a similar arrangement 14, 16, 17 to produce a reference signal in phase with the bursts in the signal from terminal 13, this signal being inverted in phase at 18 and fed to demodulator 8. The outputs from demodulators 7 and 8 are fed with the luminance signal to a matrix 19 to give red, green and blue component signals. The outputs from oscillators 12 and 17 may be added to give a signal of -(B-Y) phase which is then inverted and fed to demodulator 8. In addition the output of oscillator 12 and the inverse of the output of oscillator 17 may be added to give a signal in phase with the R-Y modulation axis of the signal at terminal 6, which is then fed to demodulator 7. Alternatively the outputs of continuous wave generators 11, 16 may be added and the resulting signals used to control the oscillators. Delay line 2 may alternatively have a delay period equal to an odd multiple of one line period.
