Title: Moulding Articles from Sheet Materials.
IPC: B29C51/10
Filed: 1967-03-15
Abstract: 1,189,685. Sheet forming. MONSANTO CO. 15 March. 1967 [15 March. 1966], No. 12197/67. Heading B5A. In a plunger assisted blow/vacuum forming machine a sheet is continuously fed between linearly reciprocable male and female die members, the female die member having a cooled web stripping plate 42. The sheet 1 is clamped about the periphery of the webstripping plate by a reciprocable ring 130 and around the periphery of a recess surrounding each individual cavity by clamping rings 120. The plungers 85 each carry a positive pressure applicator 95 comprising a conventional folded or telescopic bellows upon which is mounted a sealing ring 99. In operation, the clamping rings 120 and 130 are forwarded to press the sheet into contact with the female die member and web-stripping plate respectively, after which the plungers are forwarded to pre-draw the sheet into the cavities. During this forward movement the sealing rings engage the sheet and press it against the recesses surrounding the cavities, thereby creating a sealed space about each plunger. Compressed air is then applied to each sealed space through ducts 101<SP>1</SP> to blow the sheet from the plungers, transfer to the cavities being assisted by vacuum applied through ducts 35<SP>1</SP> located in the bore and side walls of the cavities. The application of compressed air to each space also causes the bellows to try to expand thereby pressing the sealing ring 99 more firmly against the sheet and enhancing the seal. During the drawing operation a vacuum is maintained on the underside of the web-stripping plate and prior to the separation of the die members the vacuum is relieved or reduced. After the drawing operation, the application of vacuum and compressed air is stopped and the die member separated, during the initial part of which separation the stripping plate is forwarded relative to the female die member to partially remove the shaped articles from the cavities, the plate being returned to its original position during the remainder of the separation. The articles are completely ejected from the cavities by a blast of air through vacuum ducts 35<SP>1</SP>.

Patent GB-834965-A (GB)
Title: Measuring device for radioactive fluids
IPC: G21C17/04
Filed: 1958-04-17
Abstract: 834,965. Nuclear reactors. BERGSTEDT, B. A. April 17, 1958 [April 23, 1957; Aug. 7, 1957], No. 12212/58. Class 39(4). [Also in Group XL(b)] A method for detecting and measuring the radioactivity of solids dissolved in a liquid comprises spraying the liquid into a hot gas stream to form an aerosol, filtering the aerosol in an electrostatic precipitator so that solids are deposited on a movable tape, and moving the tape past one or more detectors. The liquid, which may be the heavy water coolant of a nuclear reactor, enters the system through a pipe 10 and valve 13 and passes through a pump 12, by-passed by a valve 14, to nozzles to produce a fine spray in the chamber 25 containing hot carrier gas, which may be air or pure oxygen. The gas passes from chamber 25 to an electrostatic precipitator 28 where solid particles are precipitated on to a metal tape 29. The gas then passes to a filter 16, where fresh gas may be introduced through pipe 15, to a condenser 33 which removes the liquid and thence through an ion chamber 17 which detects any radioactive gases present and is connected to an alarm. The chamber 17 is connected to a blower 18, from which the gas passes to a junction 19 where gas may be extracted from the system through a pipe 20. After the junction 19 the gas passes to a further junction arranged so that part of the gas goes direct to chamber 25 and part goes past a heating element 26 and then to chamber 25. The tape 29, after collecting a radioactive deposit from the precipitator 28, moves past three detectors 36, 37, 38 which detect alpha, beta and gamma radiation respectively. The tape may then be fed over a long path, to allow a considerable time delay, to three further detectors for a further measurement after a known time interval.

Filed: 1960-04-07
Abstract: 957,862. Xerographic developers. RANKXEROX Ltd. April 7, 1960, No. 12331/60. Heading G2H. An apparatus for producing a suspension of finely divided xerographic developer powder particles in a gas or gas mixture comprises means to transfer the powder from a supply point to a pick up point where it is intrained in a gas, and a coarse metering means and a fine metering means, the arrangement being such that the particles not metered by the fine metering means are diverted to the supply point. In the apparatus shown a casing 20 is provided with an aperture covered by a plate 66 for passing powder into a rotatable container 28. The powder rests on a surface 32 and is passed under a blade 35 which allows only a thin layer to pass which is subsequently fluffed up by a brush 37 and passes under a second blade 36 which may be curved and is positioned so that (a) it meters the powder and directs a certain amount under a brush 38 to a position under receiving nozzles 76. (b) deflects the excess powder back to blade 35. The blades and brushes are fixed to plates 42, 44 and their height above the surface 32 may be varied. Compressed gas is forced through an inlet 55 and the outlet nozzles 76 are so positioned above the surface 32 as to establish a zone of pressure which is less than the average pressure in the enclosure so that the powder is sucked off the support and can be transferred to the xerographic plate.

Title: Improvements in or relating to apparatus for traversing a body along and between opposed walls or for anchoring a body to said walls
IPC: E21C29/02
Filed: 1944-06-29
Abstract: 594,400. Mine creepers. SPRAGG, H., and HALL, W. E. June 29, 1944, No. 12431. [Class 79 (iii)] [Also in Group XXX] An arrangement forming part of a machine which moves with a stepping motion, which machine is used for moving objects along and between opposed walls such as a roof and floor of a mine and which can also be used for anchoring an object to the walls, comprises a strut of length greater than the distance between the walls, a carriage on which the strut is pivoted resilient yielding means between the strut and the carriage to move it and the carriage into engagement with the opposed walls and means for connecting the strut or carriage to the object. As shown there are two struts side by side each comprises an H-section member 16 carrying at its lower end blocks 18 by which it is pivoted to a sledge-like carriage 10, a pin 21 passing through holes in the blocks and in the side members 14 of the carriage. At the upper end of each strut is a shoe 37 pivoted to blocks 50 by a pin 35. The length of the struts is adjustable by sliding the blocks 50 with respect to the member 16 the blocks being attached to this member by a bolt engaging in registering holes 32 on the block and in the strut. Mounted on each carriage is a shuttle member 27 which can reciprocate on a bar 29 mounted in lugs on the carriage. Springs 30 or pneumatic or hydraulic means tend to hold the shuttle in the middle position. The shuttle engages the lower end of the blocks attached to the strut and the action of the springs &c. tends to move the strut into a position at right angles to the carriage and will thus tend to move the strut and the carriage into engagement with the opposed walls of a mine. Attached to each block 18 by a pin 23 is a connecting rod 22 which is reciprocated by a compressed air motor 43 carried either by a unit as shown or by the object to be moved. The motor 43 drives an eccentric 44'which reciprocates a connecting rod 47 pivoted to a framework 48. The framework carries a pawl co-operating with a ratchet wheel 51 and is pivoted about the axis of the ratchet.wheel. As the connecting rod reciprocates the framework is oscillated and the pawl rotates the ratchet wheel in one direction of movement only. The ratchet operates a crank shaft 49 which has two cranks each connected to one of the connecting rods. When the machine is used for moving an object, reciprocation of the connecting rods causes the struts to be alternately pivoted about the shoes 37 and then on the opposite movement the strut is jammed between the walls and the object or unit moved forward. When used for anchoring a unit the strut is jammed between the walls and held by the resilient yielding means. It can be used for a haulage anchor.

Title: Improvements in or relating to coke oven door operating mechanism and methods of operating same
IPC: C10B25/14
Filed: 1937-05-01
Abstract: 496,755. Screwing-up machines. KOPPERS CO. May 1, 1937, No. 12489. Convention date, May 1, 1936. [Class 83 (iii)] Screw-operated devices for actuating the door latches of a battery of coke ovens comprises a carriage movable from oven to oven to positions opposite the doors the carriage supporting a reversible electric or other motor driving crank mechanism which is connectible to the screw devices for opening or closing the doors. In the application to a coke oven battery embodying a number of side-by-side chambers the coal is charged through openings 23 and each oven is closed at each end by a refractory-lined door 24 fitting loosely on the door frame 25. The door is sealed by means of a flexible metal frame 28 secured to the door by bolts 30 and engaging a frame surface 31. Bolts 33 are provided to adjust the flexible member to any irregularities in the surface 31. To force the door into the sealed position a pin 32 screws into a bracket 35 attached to the door and carries a loose latch member 26 which may be swung on the pin so that it engages under latch hooks 27 secured to the frame. When the pin is turned so that it unscrews from the bracket 35 the latch is first brought into engagement with the hooks and the bracket 35 is then forced forward to close the door. For the extraction of the coke the pin 32 is rotated so as to relieve pressure on the latch rods which are then turned clear of the latch hooks. A hook 38 is raised to engage with a plate 41 and break the seal after which the door is moved away and the charge pushed from the oven by a pusher mounted on the other side of the oven battery. Electric motors 42, 43, mounted on the door machine 39 in positions opposite the latch screws, drive through speed reducing gears 44, 45, cranks 46 having spring pins 53 engaging star wheels carried by the pins 32. The drive of the pins 32 is interrupted when the bracket 35 exerts the required pressure against the door. Alternatively, limit switches may be employed for this purpose. An electric circuit including a cut-out device to stop the motor when a predetermined closing pressure is reached is described in the Specification.

Title: Process of treating vegetable or animal oils obtained by extraction by solvents
IPC: C11B3/00
Filed: 1929-04-23
Abstract: 311,730. Metallges. Akt.-Ges. May 15, 1928, [Convention date]. Fats and fatty oils, purify. ing.-Animal or vegetable oils are purified before removal of the solvent used for extraction by (1) mixing the solution of oil in the solvent with dilute acid, (2) treating the separated solution with a bleaching earth or charcoal, and (3) separating the adsorbent material and removing residual solution from the latter by washing with fresh solvent. For example, the solution is agitated with dilute hydrochloric acid in a vessel b, separated from the acid, washed with water, settled out, run into a vessel e and treated with fuller's earth or charcoal forced by a pump f through a filter g to separate the adsorbent, and heated in a still i to remove the solvent. The oil is then heated to a higher temperature in vacuo in a vessel o to remove free fatty acid. Treatment with acid may be omitted replaced by treatment with an oxidizing agent, or combined with the treatment with adsorbent. Removal of fatty acids may be effected in the still i. The adsorbent is regenerated by pumping solvent from a reservoir k through the filter g and removing residual solvent by blowing with steam.

Title: Digital data processing unit
IPC: G06F9/48
Filed: 1974-03-21
Abstract: 1435671 Data processing interrupt handling INTERNATIONAL BUSINESS MACHINES CORP 21 March 1974 [30 April 1973] 12734/74 Heading G4A A control data storage area 13-16 is provided for each priority level of operation, the area corresponding to the highest priority current service request being used to control the processing system while lower priority areas store control data relating to points at which processing of other operations were interrupted, and each area is addressable by an instruction at a currently active higher priority level to transfer the stored control data to another location and replace it at the addressed area with other control data. The arrangement allows a task, which requires execution of a subroutine, for example, at a lower priority level for completion of the task, to pre-empt an interrupted operation at the lower level by storing the state of the interrupted level and replacing it with control data for performing the subroutine needed to complete the task. In a time-slicing system, a timer interrupt handling routine can be used to transfer control data relating to a lower priority user program in a first in first out storage queue, the data from the front of the queue being transferred to the appropriate area 13-16 to replace the data which is transferred to the end of the queue. Requests for service accepted by logic 29 are stored in a buffer 30 and interrupt request latches 31 are set, there being one latch 31 for each priority level. Latches 22, 23, one for each priority level are also provided to denote the priority level of the current operation in process of being executed and of any operations which may have been interrupted before completion. When a higher level interrupt request is accepted by logic 20, information from buffer 30 is transferred to the appropriate storage area 13- 16 for the new level, the corresponding latch 22 is set and the latch 23 corresponding to the interrupt level is set. The storage area 13-16 for each level includes an instruction address backup register, accumulator, conditions and indicators storage and a plurality of index registers and status backup registers. Instructions are provided to enable transfer of information between a main storage location or specified register in the storage area 13-16 of the current level and a specified register or indicator location in another level specified by the instruction. The locations and registers may be specified directly by the instructions or by the contents of current level registers specified by the instructions.
