Title: Hydraulic positioning apparatus
Inventor: VENNER MICHAEL
IPC: B23Q16/00
Filed: 1963-07-26
Abstract: 1,007,633. Hydraulic jacks. SPERRY GYROSCOPE CO. Ltd. July 17, 1964 [July 26, 1963], No. 29649/63. Heading B8J. [Also in Division B3] Hydraulic positioning apparatus comprises two telescopic jack units with a common outermost body 1 and two sets of jacks similar to each other. The following describes the left -hand set in the drawing. An end member 2 carries a piston head 4 working in a cylinder formed by a sleeve 5, the outer end of which communicates with a port 6. The inner side of the piston head 4 carries an extension piston rod 7 with a piston head 8 within a chamber 9 supplied with hydraulic fluid under pressure through a port 10. The exposed area of the piston head 8 is half the annular area of the piston head 4 within the sleeve 5. The space between the piston heads 4, 8 surrounding the rod 7 is connected to a port 11. The sleeve 5 has a piston head 12 at its outer end with an effective area twice that of the end of a sleeve 14 joined to the sleeve 5 and effectively forming a further piston head in the chamber 9 and acting as a cylinder for the inner piston head 8. The end of the cylinder in the sleeve 13 beyond the piston head 12 is connected to a port 15. The sleeve 13 itself forms a piston with a piston head 16 working in the body 1. The other end of the sleeve 13 is connected to a further sleeve 18 which forms a cylinder within which a portion of the sleeve 14 acts as a piston and which also serves as a piston exposed to the fluid in chamber 9. The annular area of this piston is half that of the piston head 16 and the space between the two piston heads is connected to a port 11. Application of the fluid pressure to all the ports 6, 11, 15, 17 as well as to port 10 moves all the pistons to their stop positions to the right as the left-hand areas are twice the right-hand areas of the associated pairs of piston heads. Venting one or other or all of ports 6, 11, 15, 17 to a tank (not shown) allows the pressure in chamber 9 to move one or other or all the pistons to their left-hand stop positions. The travel of the innermost piston head 4 is 3À2 inches, of piston head 12 is 0À2 inch and of piston head 16 is 0À1 inch. The righthand side of the apparatus provides a pistonrod 3 with three piston heads with travels of, from the innermost outwards, 1À6 inches, 0À8 inch and 0À4 inch. A range of sixty-four positions spaced at 0À1 inch over a distance of 6À3 inches is thus provided. A six-digit binary coded number may control the apparatus.

Title: Indicator display system
IPC: B61L25/04
Filed: 1959-09-01
Abstract: 874,670. Selective indicating devices. GENERAL RAILWAY SIGNAL CO. Sept. 1, 1959 [Sept. 26, 1958], No. 29781/59. Class 40 (1). In a rotary indicator of the kind positioned by a seeking arrangement governed by energization of a combination of certain ones of five leads, the indicator shaft carries a coded commutator and is driven by a motor until the energized leads are open-circuited. The transmitter, Fig. 1B, consists of ten relays CRR one of which is energized to register the digit it is required to transmit. Contacts such as 19, 20, 21 energize a corresponding combination of three out of the five leads. The indicators have coded commutators, two of the brush contacts of which make contact in each of the ten angular positions as shown in Fig. 2B. These contacts are represented as 1B, 2B, 3B, 4B and 5B in each of the indicators T1A, T1B, U1A, U1B, &c. The operator selects the desired indicator by pressing one of the buttons PBTA, PBTB, PBUA, PBUB, thereby to connect the motor M, Fig. 1A, to the negative supply. The selected indicator is then driven until the three energized leads are open-circuited, the selected digit then being displayed. Checking.-In order to ascertain that the equipment is working properly and that the indicator has arrived at the desired position, double coil relays IBCR-5BCR are connected to the five leads. One coil of each is connected to the negative supply and the other is connected through a resistance to the positive supply. Normally both coils are energized in opposite directions so that there is no response. When a positive marking appears on the lead the lower coil is de-energized so that the relay picks. If the leads are in order, and the signal sent correctly marks three of the leads, three of the relays pick. When the indicator reaches the selected position the other two leads are connected through the motor M to the negative supply. This prevents current flowing through the top coil of the corresponding relays and they also pick. All five relays therefore pick and the series-connected contacts energize a relay KCR. This illuminates a lamp to inform the operator that the number is correctly displayed and the next digit may then be selected. Specification 805,349 is referred to.

Title: Improvements in or relating to electrical circuits including automatic switches
Inventor: SCOWCROFT JOHN
IPC: H04Q3/00
Filed: 1952-11-26
Abstract: 742,185. Automatic exchange systems. GENERAL ELECTRIC CO., Ltd. Nov. 3, 1953 [Nov. 26,1952], No. 29897/52. Class 40 (4). A bi-directional switch is caused to hunt over a selected level by self-interruption of the rotary magnet circuit at contacts mechanically operated by the rotary magnet until a test wiper engages a bank contact which is connected to a suitable potential of predetermined polarity, bringing about the operation of a test relay which holds itself operated, prevents further rotary stepping of the switch, and extends the calling loop to the associated switch wipers. The switch shown has two sets of wipers with corresponding test relays HA and HB. The application of a calling loop to leads 1 and 2 brings up relays A, B and C, and incoming dial impulses are repeated by relay A to the vertical magnet V which raises the switch wipers to the wanted level. Off-normal contacts N1-N3 operate, so that relay C falls back at the end of the impulse train and completes a circuit for the rotary magnet R over its interrupter contacts R1 which are operated mechanically by the magnet armature. Thus the switch wipers are stepped over the selected level, operating rotary off-normal contacts NR1-NR2. Free outlets are marked in bank P1 or P2 by negative battery potential. If test wiper P1 encounters this marking, the associated test relay HA operates, locks, opens the rotary magnet circuit, seizes the free outlet by extending earth over wiper P1, and connects the calling loop to the seized outlet over wipers 13 and 15. Relays A and B fall back and relay C is re-energized to disconnect the test windings of relays HA and HB. If wiper P2 is the first to find a free outlet, the sequence of operations is the same except that relay HB replaces HA and extends the calling loop over wipers 14 and 16. If both test wipers P1 and P2 find free outlets simultaneously, P1 takes precedence since the operation of relays HA and C brings about the release of HB. If all outlets are engaged, the wipers move to the 11th step position where the operation of contacts S1-S3 applies busy tone from lead BT and brings up relays HB and C to stop the switch and operate an overflow meter (not shown) over wiper P1. When the calling subscriber hangs up, relays A, B, HB and C fall back and the release magnet Z restores the switch to normal. The magnet interrupter contacts may be of the kind described in Specification 657,410.

Title: Improvements in or relating to the production of ammonium salts
IPC: C01C1/22
Filed: 1930-10-10
Abstract: Gases containing ammonia and non-oxygenated sulphur compounds, such as hydrogen sulphide, are passed with oxygen or gases containing oxygen at a temperature up to 400 DEG  C. and at ordinary or raised pressure over a catalyst comprising an oxide of nickel and/or cobalt mixed with a subexcess of a water-insoluble or difficultly soluble compound of calcium, barium, magnesium, and/or silicon.  The ammonium salts so produced are separated by cooling or in an electrofilter. Industrial gases such as coke-oven gases or distillation gases may be treated directly, or the ammonia may be washed out from the gases and then subjected to the treatment together with hydrogen sulphide obtained either from the gases or in any other way: for example, the hydrogen sulphide in the gases may be converted into iron sulphide and the latter then decomposed.  According to the examples (1) a mixture of coke-oven gas with 10 per cent of air is passed at 190 DEG C. over a mixture of gypsum with 2 per cent of cobalt oxide; (2) a mixture of coke-oven gas with 9 per cent of air is passed at 245 DEG C. over a mixture of magnesium oxide with 4 per cent of nickel oxide; examples are given also of the treatment of coke-oven gases in the presence of mixtures of lime with 2 per cent of nickel oxide or with 1,5 per cent of cobalt oxide.  The Specification as open to inspection under Sect. 91 (3) (a) refers to the conversion of non-oxygenated sulphur compounds, such as hydrogen sulphide, into sulphur oxides with the aid of the catalysts described above.  This subject-matter does not appear in the Specification as accepted.

[Also in Group XXXIV] A motor driven actuator or thruster device, particularly adapted to the control of spring applied brakes is characterised in that the load spring 21 for applying the brake is contained within the casing 32 of the device. In Fig. 4, the actuator, which is of the type operated by centrifugal effect on a rotating linkage 36, 37, 38, is shown in the operative condition for compressing the spring 21 and releasing the brakes. If the motor is de-energized, the collar 49 falls and the spring 21 expands moving downwardly the connection 46 coupled to the brake levers. The drive includes an auxiliary brake, comprising a friction disc 41 that is pressed by a collar 45 against a flange 43 upon a sleeve 42, which rapidly decelerates the device when power is cut off. During an acceleration period, the disc 41 is lifted clear of the flange 43 and after the lost motion has been taken up, the sleeve 42 is raised to compress the spring 21 against the resistance of an adjustable brake shoe 44. As shown in Fig. 1, the leverage may be varied by adjusting the position of a nut 18 connecting the slot 25 in plate 16 with a rod 15.
