Title: Method of forming an image of an organ of a living body containing radioactive material
IPC: G01T1/29
Filed: 1972-10-04
Abstract: 1379084 Tomography RAYTHEON CO 4 Oct 1972 [1 Nov 1971] 45795/72 Heading H4D [Also in Division G2] In tomographic apparatus determining the distribution of radioactive isotope from a tracer fed body, e.g. thyroid gland and 11, Fig. 1, the radiation from a single point passes to an "Anger" type assembly of scintillation crystal 17 and detector array 18 via a Fresnel type grating Fig. 2, having concentric annular slits 16 in a radiation opaque slab 15, the areas of all the slits and intervening slab annulli being the same (radii varying as the square root of the set 1 to N). A hologram type of pattern is thus produced in the crystal and is displayed on C.R.T. 23 by means of known computer 19. The hologram pattern is transferred to a film 24, Fig. 4, and the image of the radioactive distribution produced therefrom by collimated laser light source 30, 31 prime image stop 35 and ground glass projection screen 36. By varying the distances of the laser optics, various depth planes in the distribution can be brought into focus and displayed using camera 37. The film 24, and laser decoding stages may be replaced by a transform computer acting directly on the outputs of the detectors 18, Fig. 5, (not shown). To enable low intensity radiation to be used, an image intensifier can detect the scintillator crystal display via a bunch of optical fibres, the intensified image being, viewed by a television camera and the video signal fed to the transform computer. The concentric grating Fig. 2, may be replaced by one Fig. 3, having curved slits forming a section of said concentric grating, each point of radiation producing three images on the scintillation crystal-one on the axis indicating the average intensity of the radiation, one displaced from the axis and being the real hologram image and the third further displaced from the axis and being the virtual hologram image. The three images can be separately analysed using shielding.

Abstract: 998,613. Pulse radar; radio receiving systems. RADIO CORPORATION OF AMERICA. Dec. 4, 1962 [Dec. 19, 1961], No. 45864/62. Headings H4D and H4L. A pulse receiver for use in DME equipment with ability to select pulse signals without distortion from one particular channel, comprises a wide band amplifier which passes without distortion pulses from the desired and adjacent channels, an " AND " gate to which these pulses are applied, a narrow band amplifier (or other channel) which selects (and distorts) the pulses from the desired channel and means to convert these into gate pulses for opening the " AND " gate on the arrival of the desired channel pulses from the wide-band amplifier. In an airborne DME system (Fig. 1) transmitter 11 transmits pairs of interrogating pulses 13, 14 spaced 12 microseconds apart and the selected ground station replies with similarly spaced pairs of reply pulses 1, 2 in a particular channel. These pulses 1, 2 derived at the receiver from the first detector 77, are applied to a broad band amplifier 26 with a pass-band some three channels wide and so able to pass sharp pulses without distortion. In order to eliminate pulses from adjacent channels the output from amplifier 26 is passed via second detector 27 through a delay line DL to an AND gate 28. The opening of the AND gate is controlled by selecting the pulse pairs from the desired channel from the output of broad band amplifier 26 by a narrow band amplifier 31, the distorted, i.e. broadened output pulses 11, 2<SP>1</SP> of which are converted in known manner into gate pulses 2A coincidental in time with the second pulse of the respective pairs (delay line DL is necessary to effect coincidence) by limiter 34 and decoder 36. Only the second pulses 211 of the desired sharp pulse-pairs 1<SP>11</SP>, 211 from the broad-band amplifier are thus gated and fed through limiter 20 to the known search and track circuit 21 for DME measurement. In another embodiment, Figs. 5, 6 (not shown) the wide and narrow band amplifiers are replaced by discriminators, the D.C. outputs of which are added to produce the narrow band broadened pulses corresponding to 11, 2<SP>1</SP>, Fig. 3, for application to the limiter 34.

Abstract: 964,947. Telegraphy. TELETYPE CORPORATION. Dec. 13, 1962 [Dec. 26, 1961], No. 47065/62. Drawings to Specification. Heading H4P. In an error-detecting telegraph system in which characters are transmitted in blocks a parity check is made on each of the bit levels of the complete block. When the end-of-block character is recognized the parity check signal is sent to the receiver, where it is compared with the parity check derived from the received block, it being arranged that the recognition circuit is operative only when at least one of the parity check circuits is in a state of transition. In the embodiment described the block of signals comprises one line of characters and is therefore followed by a carriage return signal. The latter is recognized as the end-of-block signal. Five bi-stable relay circuits are provided at both the receiver and the transmitter, each circuit performing a parity check on the corresponding level of the 5-bit code signals used in each block. Each circuit is such that on receiving a space bit it remains in its present stable state but on receipt of a mark bit it passes from one stable state to a transition state which changes to the other stable state at the end of the mark bit. Since the carriage return signal is SSSMS in the coding used here, presence of this signal can be recognized by the fact that only the fourth level parity circuit is in transition. When this is determined the transmitter tape drive is stopped and the states of the parity circuits are transmitted. At the receiver the parity circuits have already set up a check signal derived from the received block of signals, and recognition of the carriage return signal causes the derived check signal to be compared with the received check signal. The check signal is punched on the receiver tape but tape feed is stopped so that the next character received, which will be LTRS and is formed of five mark bits, cancels the check signal perforations. Upon detection of an error visual and aural alarms are actuated. In addition, a sixth perforation may be made by the LTRS code which follows the erroneous block, the receiver closed down for a short period and the transmitter informed of the error. If desired, the short close-down can be extended in time to allow the operator to over-punch all the characters of the erroneous block with the LTRS code. Specification 562,551 is referred to.

In a tumbler drier, air is passed into, through and out of the horizontally mounted, perforated drum 20, Fig. 1, along a path defined by baffle walls and is heated prior to entry to the drum in a heat-exchanger 50 utilizing low-pressure steam at 15 p.s.i.g. or less, and the heatexchange is effected by restricting the area of the path in a hopper-shaped heat-exchange support 76 so as to cause eddy currents in the heatexchanger. The air is drawn through the heatexchanger and support 76 and then through vertical deflector plates 92 to an opening 93 in a baffle 94 surrounding and closely conforming in shape to the drum for passage through the drum and exit through a discharge opening 96 in the baffle under the influence of a suction fan in the form of a backward wave impeller 40. The air is finally exhausted via a resilient lint trap which, on cessation of the fan, flexes to allow the lint to fall to the lower inner floor of the drier casing for removal by hand. The heat-exchanger 50, Fig. 3, comprises a frame 52 in which the steam conduits 56 are formed with fins 70 and have no more than four parallel horizontal tube sections joined by loops 58, 60 and are connected in parallel by an inlet and outlet header 62, 64; and the fins are directed at right-angles to the inclined walls of the hopper-shaped support 76 to deflect a portion of air thereagainst to aid the heat-exchange process.

Abstract: 1475199 Suppressing contact chatter BOSSE TELEFONBAU GmbH 1 Nov 1974 [3 Nov 1973] 47312/74 Heading H3P A circuit for suppressing contact chatter comprises a D flip-flop which has its D input 24 connected to the circuit input 20 and is switched by a pulse at its clock input 23 a predetermined time after application or relase of a pulse to the input by which time contact chatter will have ceased. The input pulse at 20 is connected through an EXCLUSIVE-OR gate 2 and an AND gate 3 to reset and start a binary counter 1. When the count is complete, the output of counter 1 produces the delayed pulse to switch the flip-flop, and start an output pulse at 30. The flip-flop output 28 simultaneously changes from high to low so that the circuit is ready to perform the same switching sequence when the trailing edge of the input pulse arrives. To avoid phase uncertainty in the output pulse due to the clock cycle time, the counter 1 may be started by the input pulse after a short fixed delay instead of waiting for the next clock pulse, Fig. 2 (not shown).
