Title: Technetium-dimercapto aliphatic complexes and their use in kidney imaging
IPC: A61K51/00
Filed: 1976-04-20
Abstract: A radioactive pertechnetate is reduced in the presence of an aliphatic C2-C15-dimercapto compound which contains a particular number of hydroxyl, carboxyl and sulpho groups for every 3 C atoms, e.g. dimercapto-succinic acid, -glutaric acid or -adipic acid, at pH 1 to 3. The resulting complex compounds of technetium-99m accumulate in the kidney and remain there considerably longer than when they are prepared at neutral or alkaline pH; this means that scintigraphic investigation can be carried out with a conventional gamma camera in place of a high-performance instrument.

Title: Improvements in or relating to return devices for the bogies of rail vehicles
IPC: B61F5/24
Filed: 1944-08-22
Abstract: 589,699. Centring devices for bogies of rail vehicles. SCHWEIZERISCHE LOKOMOTIVUND MASCHINENFABRIK. Aug. 22, -1944, Nos. 16015 and 16016. Convention dates, July 10, 1943, and June 27, 1944. [Class 103 (vi)] A device for returning the longitudinal axis of a rail-vehicle bogie into alignment with the longitudinal axis of the body exerts a centring force decreasing substantially to zero beyond a predetermined angular movement of the bogie. The Y-lever 12 is pressed against two studs 13 fixed to a box-girder 2 on the truck frame by the spring 14 through a cap piece 23 and a block 25 sliding between jaws 22 and pivoted at 24 to the lever 12. On slight deviation of the bogie from alignment the lever 12 pivots on one of the studs 13 and the restoring pressure of the spring 14 is transmitted through a rod 16 to the bogie frame to which the rod is pivoted at 17. On further deviation, such as occurs when the vehicle enters a curve, the rollers 27 on the cap piece 23 engage guide tracks 28 fixed to the girder 2, so preventing or reducing the action of the spring 14 on the rocking lever 12 which is then retained on one of the studs 13 by a spring 33 which provides a slight centring force. In a further embodiment the lever 12 is replaced by a pivotal arm whose forked end slides on a block pivoted to the girder 2, while the outer portions of the guide track 28 form circular arcs about the pivot. 21 as centre, so that when the roller 27 is on these portions no centring force is applied to the bogie. A central depression, against the flanks of which the roller 27 bears in its median position, is formed in the guide track 28 and is of such a shape that as the bogey moves out of alignment the restoring force first increases and then decreases to zero. The device is preferably applied at each side of the truck, and the studs 13, guide track 28 and pivot 21 may be on the bogie while the pivot 17 is on the truck frame. Slide blocks pivoted to the lever 12 at 15 and engaging transverse slot guides on the bogie frame may replace the links 16. The invention may be applied to a bogie as described in Specification 587,321.

Abstract: 672,493. Television. WESTERN ELECTRIC CO., Inc. June 27, 1950 [June 30, 1949], No. 16017/50. Class 40 (iii). [Also in Group XL (c)] In a scanning circuit for a cathode-ray tube blanking pulses are produced from the flyback voltages of the horizontal and vertical scanning waves and are applied to the cathode or control grid of the C.R. tube via a rectifier to cut-off the electron beam during the fly-back periods. The Figure shows a portion of the scanning circuit of a C.R. tube in which the frame and line deflecting coils are fed from windings 41, 44 of output transformers T1, T2, respectively. Two additional secondary windings 42, 45 are connected in series with a diode rectifier 46 to the cathode circuit of the C.R. tube so that during the presence of the high level positive going pulse which is produced across windings 42, 45 during the frame and line fly-back periods respectively, diode 46 conducts to apply a positive blanking pulse to the cathode of the C.R. tube to suppress the electron beam. In a modification, Fig. 3 (not shown) the auxiliary secondary windings are connected in parallel to the cathode of the C.R. tube via separate diodes. In a further modification, Fig. 4 (not shown), the fly-back pulses are produced from across tappings on the normal secondary windings of the output transformers or the pulses may be produced across coils associated with the frame and line deflecting coils of the C.R. tube, Fig. 5 (not shown). Crystal diodes such as germanium may be used instead of valve rectifiers.

Abstract: 515,390. Distilling and cracking hydrocarbons. HOUDRY PROCESS CORPORATION. June 1, 1938, No. 16390. Convention date, July 10, 1937. [Class 32] Composite vapour mixtures produced by the high temperature conversion or distillation of hydrocarbon materials, e.g., petroleum, shale oil, bitumen, coal, lignite, and distillates or residues thereof, are separated into fractions of high and low boiling point by passing them in the vapour phase through a mass of solid porous contact material, which has little or no catalytic activity but a preferential absorption for the higher boiling fraction, so that the lower boiling fraction passes through the separation zone while the heavier fraction is absorbed by the contact material and subsequently ejected therefrom by a hot gaseous medium and preferably recycled to the first or a further conversion zone. The contact material comprises synthetic or natural porous material, e.g., silica or alumina gel in the form .of bits, fragments, or moulded pieces, and any catalytic activity maybe reduced by prolonged treatment at high temperature. The contact material is charged into separators 3 maintained at 750-950‹F. and preferably provided with distribution means as described in Specifications 414,779, 346,967, 345,511, and 345,496.

Abstract: 581,531. Permutation locks. ROSENFELD, P. W. Aug. 30, 1944, No. 16447. [Class 44] A permutation lock which includes a retractable bolt or the like comprises at least two rotatable coaxial cylindrical elements having recesses adapted to be brought into register by the operation of a central spindle, which is then moved axially to cause an arm thereon to enter the registering recesses and so move into a position to engage the bolt to withdraw it. The lock comprises a casing 5, Figs. 2 and 6, having a bush 12 fixed in the back plate, through which passes the operating spindle 1, carrying a handle 2 and pointer 4. Mounted to rotate on the bush are two cylindrical elements 7, 8, having pins 17, 19, 21, by means of which they can be set successively by the operation of a lever 6 on the inner end of the spindle 1. Recesses 18, 20 in the cylindrical elements are thus brought into register opposite a notch 22 in the bolt 23. The lever 6 is then set to the same position, and caused to enter the recesses by pulling in the handle ; the end of the lever enters the notch 22, and the handle is then turned to retract the bolt. On continued rotation the lever leaves the notch 22, rides up a ramp 28 formed on a fixed collar 25 concentric with the cylinders and is thus withdrawn from the recesses in the cylinders, which are thus left in such a position that they must be reset to operate the lock again. At the same time the bolt is shot to its locking position by the action of the spring 24. Means for locking the bolt in either shot or retracted position are provided in the form of a lever 35, fixed to a pin 31, operated by a knob 32, which may be turned to engage on one or other of two pins 40, 41, Fig. 4, on the bolt 23. A spring 36 normally holds the lever 35 in midposition out of engagement with either of the pins.
