Title: Apparatus for handling components
IPC: B23P19/06
Filed: 1975-03-03
Abstract: 1489180 Dispensing articles; rotary conveyers PLESSEY CO Ltd 3 March 1975 [19 Dec 1973] 58937/73 Headings B8S and B8A In apparatus for handling components a disc 32 has holes (40) formed therein in a spiral configuration, Fig. 3 (not shown), into which holes (40) the components may be fed from feeder means (2), Fig. 1 (not shown), and the components may subsequently be removed from those holes (40) by remover means comprising a head 42, the disc 32 being connected by a central shaft 34 to an indexing plate 36 which is rotated in order to rotate the disc 32 relative to the feeder means (2) or to the head 42 by one hole at a time. The indexing plate 36 has holes 41 formed therein in the same configuration as those in the disc 32, and rotational movement of the plate 36 is effected by means of indexing apparatus 62 which comprises a pin 70 (Fig. 5) which is locatable in each of the holes 41, the pin 70 being movable from left to right in a slot 72 and also being vertically movable downwardly against the action of a spring 74. When pin 70 is engaged in a hole 41 compressed air is fed through a passage 64 to move the pin 70 to the right and thus index the plate 32 (and thus disc 32) one position on. Compressed air then forces pin 70 downwardly and compressed air fed through a passage 66 causes pin 70 to return to its initial position where it enters the next hole 41 under the action of spring 74. The head 42 comprises an air passage (46) in a suction tube (44), Fig. 4 (not shown), which sucks the components out of the hole (40) in the disc 32 located therebelow, the head 42 being mounted on an arm 78 for both vertical and rotational movement relative to disc 32. In Fig. 1 (not shown), the disc 32 is represented by the numeral (4) and the indexing means (6) comprises an indexing plate (36).

Title: Tubing swage utilizing explosives
IPC: B21D26/08
Filed: 1972-12-20
Abstract: 1406499 Explosive shaping DRESSER INDUSTRIES Inc 20 Dec 1972 [12 Jan 1972] 58951/72 Headings B3Q and B3J A swaging device 2 is lowered through a well tube 1, to a point below the tube end 22 which has been flared outwardly during cutting of the tube, in the form shown in Fig. 1 in which a ring 3 of explosive material is held in loops by a spring cage 14 and located in a sleeve 4 while a spring 6 is compressed against a mandrel 8 in the sleeve by an electrical squib 9, The squib is fixed to an upper housing 10 and electrically connected to equipment on the surface by a lead 11. Mounted on the cage 14 is a blasting cap 16 connected to surface equipment by a lead 17 passing through a tube 18. On firing of the squib 9 the spring 6 forces the sleeve 4 upwards, releasing the cage 14 and thus the explosive ring 3 and allowing springs 5, 51 &c. to open out flat. The device is then raised until the springs 5 &c. abut, and the ring 3 surrounds, the deformed end 22 of the tube 1. The blasting cap 16 is detonated and the explosive force of the ring 3 is transmitted via a steel band 21 lining the ring to the end 22. The mandrel 8 and the sleeve 4 prevent excessive swaging. Should the sleeve, mandrel or bull plug 15 become stuck in the tube 1, the relatively weak tube 18, of e.g. aluminium, is severed by drawing the housing 10 upwards, the housing then being repeatedly dropped on the sleeve &c. to dislodge the obstruction. To swage an inwardly-deformed tube outwardly the swaging device (not shown) includes a collapsible anvil which is passed through the tube in collapsed condition and then expanded to surround the tube end, and the explosive charge is placed within the tube end.

Title: Tone transmission system
IPC: H04Q1/45
Filed: 1969-12-11
Abstract: 1,254,230. Automatic exchange systems; voice frequency signalling. INTERNATIONAL BUSINESS MACHINES CORP. 11 Dec., 1969 [15 Jan., 1969],No. 60451/69. Headings H4K and H4R. In a system for transmitting alpha-numeric characters over a telephone system, each character is transmitted in the form of two tones transmitted in series and within the duration of a third transmitted tone. The system described can be used for transmitting punch card data to a central punch. The Specification refers to prior art system which transmit characters as three simultaneously transmitted tones each selected from a group of four tones and states that additional frequencies (e.g. bent frequencies) generated during transmission over a telephone network cause errors. By employing transmission of only two tones at a time, one from each of two groups of four tones, the tone frequencies can be selected to avoid such errors and the tone present throughout the transmission of a character is longer than any simulated signal due to speech. As described, a keyboard sender has one key for each character. When a key is depressed it closes a bank of contacts. One contact pair enables one of four inputs on an oscillator causing it to generate a tone from one group, a second contact pairsimilarly enables a second oscillator to generate a tone of the second group and a third contact pair enables a timer which after a short interval operates a changeover switch to disconnect the second contact pair and to cause a fourth contact pair to enable a different input on second oscillator, causing the tone of that oscillator to change. The Figure shows a detector. Actuators 47 to 50 respond to tones of the first set giving outputs on corresponding lines 55 to 58 and actuators 67 to 70 similarly provide outputs on lines 75 to 78 in response to tones of the second set. OR gates 59 and 79 connected lines 55 to 58 and 75 to 78 to an AND gate arranged to respond while one tone of each set is present resetting bi-stables 81 to 84 and enabling a timer 66 which provides an output if its input is enabled for a predetermined time. Resetting of the bi-stables enables AND gates 90 and 85 to 88 such that one bi-stable is set corresponding to the detected tone of the second group. The timer times out while the second transmitted tone of the second group is being received and enables and gates 61 to 64, 91 to 94 and 95 to 98 to provide three simultaneous output (each a marking on one out of four lines) one for each tone of the character.

Title: Analogue to digital converter
IPC: H03M1/00
Filed: 1969-12-24
Abstract: 1282729 Analogue to digital converters INTERNATIONAL BUSINESS MACHINES CORP 24 Dec 1969 [15 Jan 1969] 62808/69 Heading G4H A dual ramp analogue to digital converter for converting an input analogue signal 12a ... 12n to a digital representation of the magnitude of the input signal comprises an integrator including an amplifier 10, the integrator being subject to an initial step in output after which it integrates the applied analogue signal over an interval determined by a control 16 and being subject to a second step in output equal and opposite to the initial step on removal of the applied signal, the integrator then integrating a reference signal E R . An address signal applied to the control 16 causes a channel select 23 to select one of the analogue inputs which is fed to the non-inverting input 26 of the amplifier 10. The control also closes a gate 38 to earth a resistor 20r, thus producing a non-inverting feed-back integrator which generates a ramp output voltage by integrating the analogue input. An oscillator 34 is started simultaneously with the start of the integration and supplies pulses to a counter 18 via the control 16 until the counter is full. The control then switches off the gate 24 associated with the selected input and closes a gate 22 to generate the second step referred to above. The gate 38 is opened and the reference voltage E R  of appropriate sign is applied to the inverting input 32 of the amplifier. The reference voltage is integrated as the counter 18 steps at the same rate as before until a comparator 14 senses that the output of the amplifier has reached the initial level, the counter then displaying a digital representation of the unknown analogue voltage. In a modification, the amplifier is provided with a selectively variable gain control.
