Abstract: 1,144,215. Preparing erythrocytes for immunochemical use. ORGANON LABORATORIES Ltd. 28 June, 1966 [28 July, 1965], No. 28963/66. Heading B1X. An aqueous suspension of erythrocytes treated with one or more tanning agents, is dried and heated at above 30‹C, to provide a product which can be compressed into tablets for storage and use in immunochemical determination. The erythrocytes may first be sensitized with an antigen or this may be done subsequently. Other materials may be present in the suspension, e.g. tableting auxiliaries such as fillers (saccharose, mannitol, lactose, urea), lubricants (boric acid, starch, carbowax (Trade Mark) and magnesium stearate), disintegration agents (starch, alginic acid) and substances used in the determination e.g. buffers (monopotassium and disodium phosphate), sodium chloride, EDTA and albumin. Alternatively, these auxiliaries may be mixed individually or as a spray-dried mixture, with the treated ethythrocytes before tableting. The drying may be performed by lyophilisation, and the heating by fluidisation in a dry gas stream at 50- 120‹C for 1-10 mins, but preferably drying and heating are performed simultaneously by spray drying e.g. at 75-140‹C. In the Examples the erythrocytes were tanned with formalin with or without tannin, but the use of inulin, hydroquinine, bis-diazo benzidine, acetaldehyde, pyruvic acid aldehyde and glyoxal as tanning agents (mordants) is mentioned. In the Examples, the erythrocytes are sensitized with HCG, but serum gonadotrophin, growth hormone, serium albumins, gamma globulins, insulin, luteinizing hormone and tetanus toxoid are other antigens mentioned.

Title: Improvements in x-ray apparatus for measuring stress in metals
IPC: G01N23/205
Filed: 1939-10-30
Abstract: 533,337. R÷ntgen-ray apparatus. PRISTON H. R., and THOMAS, D. E. Oct. 30, 1939, No. 28979. [Class 98 (i)] In X-ray apparatus for determining stress in metals a film-holder is carried by a tubular fitting adapted to set the distance between the film and specimen accurately by means of a removable distance-piece carried by it. As shown, an X-ray tube a of the continuouslyevacuated type is carried by a bracket b which is adjustably attached to the frame f by parallel links e and a second rod g engaging a nut h on the frame. The tube is hinged to the bracket b and secured in adjustable angular position by means of a slotted quadrant c. It is evacuated by a flexible tube i. A tubular fitting l is secured to the front of the tube by screws passing through diametral slots in its flanged base and engaging a ring k secured into the tube, so that by rotating the ring and sliding the fitting in the direction of the slots the axis of the fitting may be made to pass through the focus of the rays. Before mounting the film-holder on the fitting a sleeve o, in which a distance-piece p is slidably mounted, is slid or screwed on to its front end and the X-ray tube is adjusted until the tip of the distance-piece touches a feeler q inserted between it and the specimen c. Alternatively, the adjustment may be made by completion of an electric circuit including the distance-piece and the body when contact occurs. The sleeve and distance-piece are then removed, and the film-holder is placed on the tubular fitting. This comprises a tray r in which the film is held by a mask t secured by springs u. It is held in position by a spring l compressed by a cap z screwed on to the nose of the fitting and apertured for the passage of the rays. In cases where the incident rays are obliquely directed on to the specimen the position of the axis of the rays in relation to the film is determined by a device comprising a plunger fitting into the tubular member l and carrying a cross-bar on which two prickers are mounted, by which two pin-holes are made in the film, equidistant between which the desired point lies.

Title: Improvements relating to colliery and like winding gear
IPC: B66B5/08
Filed: 1923-11-17
Abstract: 220,521. King, H. J. H. Nov. 17,1923. Overwinding and overspeeding, preventing.- In apparatus for the prevention of overwinding and overspending of colliery and like winding-gear which is fitted with dash-pot mechanism operable to ensure the gradual application of the brake during the main part of the wind, but cut-out automatically at a danger-zone point near to the end of the wind so that from this point onwards the brake will be applied rapidly, a separate bypass having a release valve of large diameter is opened in the dash-pot mechanism at the dangerpoint, either by the bridle mechanism used in known forms of overwinding-gear or by cammechanism. Figs. 1 and 3 show the invention applied to overwinding gear of known construction in which sliding nuts F, G are moved correspondingly to the cages, and in the event of an overwind, the nuts F contact with and rotate with collars J thus operating the lever K to rotate the shaft L, and releasing the catch M which frees the shaft O and enables the spring R to operate the bell-crank P. Movement of the bell-crank P operates a second bell-crank T which is connected to the brake-operating shaft a. In the event of excessive speed during the main wind, the bell-crank T is operated directly from the stepped member g which is positioned by the governor and is operated by the second nut G. This nut G also lifts a lever k positioned by the governor to rotate the shaft L in the event of excessive speed towards the end of the wind. To prevent the brake being applied by unintentional movement of the lever K, the latter is normally locked by a bridle member f which is released by the nut F shortly before it operates the lever K. The shaft L also is operated by the falling of a weight p in the event of failure of the power supply causing a release of the pressure in the cylinder n. In accordance with the present invention a dash-pot cylinder 7 is fitted to the apparatus and connected to the brakeoperating systems at the bell-crank P. Normally the fluid is bye-passed through a small hole 11 which ensures a gradual application of the brake, but when the bridle f is tripped at the entering of the danger-zone, an arm 17 opens the valve 13, so that in the event of the shaft L being rotated at this point by any of the previously-described mechanisms, the piston 8 is freed to allow the rapid application of the brake. Fig. 5 shews the invention applied directly to the brake-eng.no of colliery winding-gear. In this case the falling of a weighted brake arm 33 rotates the shaft 34 to apply the brake, and the governor controls the movement of an arm 35 which releases latching-mechanism normally supporting the weighted brake-arm. The dash-pot cylinder 31 normally prevents the rapid application of the brake, but near the end of the wind a cam 23, geared to the winding-drums. allows the spring 44 to depress the lever 43 and swing the pivoted lever 26 to open the by-pass valve at the end of the stem 29.

[Also in Groups XXI, XXIX and XXXII] In an earth boring rig pipe sections are removed from or supplied to the drill string by hangers 100 running on a railway 10. The railway comprises an endless rail 107 having a removable section 116 forming part of a batcher 12, adjustable stops being provided for the rail at either end of the section 116. A number of hangers in excess of those loaded is carried by the railway, each hanger having a support arm 105 with roller 106, and a spring-loaded, projection 108 which is engaged by a conveyer chain 110 co-extensive with the rail. As each pipe section is removed from the string the spinning-off mechanism 44 swings the section so that its upper end enters a hanger and is held therein by catches 101. The loaded hanger is moved to the section 116 by the chain, the stop at the discharge end of the section 116 being operative. When the batcher is full the other stop becomes operative, and the section 116 together with the batch of loaded hangers is lowered by a cable 117. The lower end of the pipe sections are received in a trolley 6 running on rails 121. The trolley carries pipe separators 127 and has racks 123 engaged by pinions 124 mounted on the rig frame. If the trolley is loaded as shown in Fig. 12, the lower ends of the batch of pipe sections passes between separators 127<SP>A</SP>, 127B. As the pipe sections engage the bottom of the trolley, cams 130 are lowered to move the separator 127<SP>A</SP> into contact with the batch of pipe sections suspended from the hangers. The hangers are released from the batch of pipe sections by pressing rods 103, the batch of hangers is raised, and the cams move upwardly to move the separators 127<SP>A</SP>, 127<SP>B</SP> and the batch of pipe sections to the right to rest against the previously stacked pipe sections. During this movement a rack 132 on the cam moves a ratchet wheel 122 driving the pinions to move the trolley into position to receive a further batch of pipe sections. The section 116 is returned to the rail 107, the stops at the ends of the batcher are released, the empty hangers are removed from the batcher by the chain, and the stop at the discharge end of the batcher is operated so that the batcher is ready for the next batch of loaded hangers. When used for supplying pipe sections to the string, the ratchet on the wheel 122 is reversed and means over the string are provided for the operation of the rods 103.

Title: Improvements in transistor amplifying circuits
IPC: H03F3/04
Filed: 1949-11-15
Abstract: 692,352. Transistors. RADIO CORPORATION OF AMERICA. Nov. 15, 1949 [Dec. 30, 1948], No. 29239/49. Class 40 (iv). [Also in Group XL (c)] An amplifier comprises a semi-conductor body having a large area electrode and two further electrodes of smaller area, the input being applied between the large area electrode and one of the further electrodes, and the amplified output being taken from between the two further electrodes. Fig. 2 shows a transistor arrangement comprising a block of N- type semi-conducting material with base electrode 4, emitter electrode 2 and collector electrode 3, and bias sources 5 and 6. The circuit is arranged in "grounded emitter" form, in which the input signal is applied between base and emitter electrodes, and the amplified output appears in the load resistance R L  connected between collector and emitter electrodes. This arrangement provides an increased input impedance which may be infinite, so that a power gain may be achieved which is greater than that provided in the normal " grounded base " circuit. Under certain conditions, the input resistance may be negative. In Fig. 8, a network 32, 28, 30 is provided in parallel with the input signal source 8, and the direct current flowing to the base electrode due to the collector bias source 6 provides a means of biasing the base electrode relative to the emitter electrode. The parallel circuit 32, 28 may be resonant at the signal frequency to provide increased impedance in the shunt circuit. Modified forms of emitter and collector electrodes are described in which either or both may consist of a group of contacts. The elements of each group may be connected together, or may be separately biased. The elements of one group may surround the element or elements of the other, or alternatively one of these electrodes may consist of a point contact surrounded by the other electrode in the form of a cylinder. These electrodes may be rounded or may consist of small areas instead of points, the collector and emitter electrodes having different areas, which may be evaporated on to the crystal surface.
