Title: Pipe racking apparatus
IPC: B65G47/84
Filed: 1970-09-04
Abstract: 1292708 Storage device BYRON JACKSON Inc 4 Sept 1970 [22 Oct 1969] 42564/70 Heading A4T [Also in Division B8] Pipes S are fed along selected storage racks 39b, 39c, 39g and 38, Fig.2, by a conveyer 103, Fig.4. There is a series of each of the vertically spaced assemblages of racks shown in Fig, 2, laterally spaced horizontally, Fig.1 (not shown), and there is a single conveyer 103 respective to each assemblage. Each rack 39b, and a member 39a, are vertically slidable on a post 22 under the action of a fluid cylinder 49. This enables the racks to be progressively spaced and makes room for the conveyer 103 to be inserted between the racks. A roller (67), Fig.3 (not shown) on a mounting boss 51 of an associated rack normally coacts with the periphery of the next lower boss. The roller is connected so as to operate a valve 66, the action being such that when the associated rack is raised, the roller runs off on to the periphery of the post and causes a fluid cylinder 59b to bring about retraction of a seat 56 which otherwise is positioned to receive a pipe S. The conveyer 103 consists of an endless chain 122 carrying pipe-engaging  elements 140. The chain is reciprocated in steps by the action of a fluid piston-and-cylinder unit 152. This carries dogs 165, 166, Fig.11, which respectively drivingly engage links of the chain for movement of the chain 122 in left or right directions, as viewed in Fig.11. Each pipe is drawn into the zone of travel of the conveyer elements 140 by the action of a retractable finger 212, Fig.20. This is extended and retracted by the action of a fluid cylinder 201. A friction brake acts against a sprocket (123), Fig.9 (not shown) of the conveyer 103 to prevent its inadvertent movement. Change in elevation of the conveyer 103 is adjusted by the action of a fluid cylinder 109 and associated haulage tackle 115. (for figures see next page)

Abstract: 1409752 Numerical control SPERRY RAND CANADA Ltd 15 Sept 1972 [17 Sept 1971] 42886/72 Heading G3N In a numerical control system, in which data from sources 10 or 12, in the form of data words comprising letters corresponding to a location in core memory 34 in which the word data is to be stored, the data can be called up from the memory in a sequence derived by comparing the letters with a predetermined (alphabetical order) sequence of letters. The data words, see Fig. 3 (not shown) can thus be read in, in any order. The magnetic core memory 34, see Fig. 2 (not shown) comprises addressable sections (56, 58, 60, 62, 64, 66) in which data appertaining to U or X axis tool offset; W or Z tool offset; feedrate and spindle speed overrides and supplemental co-ordinate data can be stored, as well as active and buffer sections (52, 54) The buffer section (54) enables tool control to continue as fresh data is read in, sections (52 and 54) being used to combine incoming data with offset and over-ride data to provide command data. Incoming data words include a buffer bit, which is changed when the word is processed to provide command data, thus ensuring that such data is not reprocessed. The command data may control, as well as positioning, tool change, feedrate, spindle speed and coolant supply. Offset data appertaining to U or X, W or Z contains information defining that one of axes U or X; W or Z resp. to which the offset is to be applied. Position control. The command data has actual position data derived from a member driven resolver subtracted from it in arithmetic unit 28 to derive an error signal applied under control of unit 30 to machine drives via d/a converters. Distance-to-go signals which can be displayed at 50 are updated until all of them are zero corresponding to the completion of a move, whence a hold mode is instituted.

Title: Control system for a building heating/cooling system
IPC: F23N5/14
Filed: 1974-03-20
Abstract: 1468394 Temperature control MAXITROL CO 20 March 1974 [4 April 1973] 42948/76 Divided out of 1468393 Heading G3R [Also in Division H3] In a building temperature control system, a first switch SW2 selects between heat H, cool C and off O positions and a second switch SW3 controls a blower. A temperature sensor RT causes circuit 16 to operate a coil MR and relay K1 to effect heating, as described in the parent Specification, provided the switch SW2 is in the H position and the sensed temperature is too low. In the C position, the same circuit effects cooling if the temperature becomes too high. In the 'auto' position of switch SW3, the blower comes on automatically with the cooling means. Cooling and blowing are switched on by the respective relays KC1 and KB. The invention provides for a positive feedback, via the components K1a, R12 and CR7, to the gate of SCR2. As soon as the relay K1 is operated by initial triggering of SCR2 to effect, as described in the Parent Specification, energisation of the coil 14c of the on - off gas supply valve (14) Fig. 4 (not shown), contact K1a of that relay closes to complete the feedback path and so reinforce the triggering of SCR2.

Abstract: 1,253,908. Moulding carbon electrodes. VEREINIGTE ALUMINIUM-WERKE A.G. 28 Aug., 1969 [4 Sept., 1968], No. 42996/69. Heading B5A. In the moulding of a crumbly carbon mass to form green carbon electrodes for the electrolytic production of aluminum, the density and porosity of the moulding are respectively increased and decreased by evacuating the mass and the mould before and/or during compaction by vibration under a covering weighted plate 9. In the Fig. 3 embodiment, the mass 8, which may include binding agent, is contained in a mould box 5 which is clamped by means 6, and sealed by means 7, to a table 1 which is supported on springs 4 and vibrated by contra-rotating eccentric masses 2 and 3. The covering weight 9 is rigidly suspended by tubes 26, 29 from a beam 11, which may be raised and lowered by a hoist 12. A plate 13, which is sealingly slidable on the tubes 26, 29 closes the open upper end of the mould 5, against a seal 14, to define a sealed mould enclosure 19 with a plate 17, which is fixed to the tubes 26, 29 and slidingly engages the mould interior at a seal 18. A further sealed mould enclosure 20 is defined beneath the plate 17 and includes the mass 8, via a peripheral clearance 31 around the plate 9. After lowering the plate 9 into the vibratory mould above the mass 8 the enclosures 19 and 20 are evacuated through a connection 22, the former via valve 23, flexible pipe 25, and an outlet 27 from the interior of tube 26, and the latter via flexible pipe 28 and an outlet 30 from the interior of tube 29. At a vacuum of e.g. 50 torr, the plate 9 is lowered to compact the vibrated mass 8, whereafter the valve 23 is closed and a valve 24 is opened to replace the vacuum in enclosure 19 by atmospheric pressure to provide additional loading on the plate 9, during further vibratory compaction of the mass 8. In the Fig. 1 embodiment (not printed), the plate 17 is omitted to define only a single sealed enclosure in the mould, which is evacuated by a direct connection to the side of the mould above the plate 9.

Abstract: 1,227,364. Pilot gain control. SIEMENS A.G. 13 Sept., 1968 [15 Sept., 1967], No. 43556/68. Heading H4R. In a pilot controlled line communication system including controlled repeaters and intermediate repeaters the output signal level of the controlled repeaters is controlled by means in which it is compared with a dynamic reference voltage which is varied in a manner inversely proportional to the variations of the amplifier input voltage by means of a control voltage proportional to the amplifier input voltage. The pilot in the input U E , Fig. 2, is extracted and rectified in a unit 4 to produce a voltage V stor  from which a fixed voltage U soll  is subtracted to obtain a residual signal #U stor  representing the change in input level. The residual signal is compared with a voltage U ist  derived from the output pilot to the following section to produce a signal #U which controls a resistor R which may be an indirectly heated one through a regulator 6, and reduces the signal #U to zero. In a modification, Fig. 3, the pilot is tapped only at the output side of the amplifier, and a voltage portional to the input signal V e  is obtained from the product of the output voltage V a  and a value proportional to that of the control resistor R developed in a transistor mixer 8.
