Title: Improvements in and connected with containers
IPC: B65D5/70
Filed: 1955-10-04
Abstract: 773,129. Cardboard containers. MILLAR, A. L. Dec. 2, 1955 [Oct. 4, 1955 ; Oct. 11, 1955 ; Oct. 13, 1955 ; Oct. 24, 1955], Nos. 28171/55, 28870/55, 29135/55 and 30286/55. Class 18. In a container having a push-in flap 8 adjacent a closed end, the closed end has a line of weakness 11 intersecting the hinge 6 of the flap so arranged that by squeezing the sides of the container after the separated flap has been pushed inwardly the closed end and flap assume an outwardly arched formation to maintain the flap in a position to afford an unobstructed pouring aperture. A rectangular container has sides 1, 2 having extensions forming flaps 3, 5 adapted to fold inwardly on fold lines 4, 6, the flaps 5 have central slots 9 and weakened lines 10, the flaps 3 have weakened lines 11 and the semi-circular push-in flap 8 is formed by a weakened line 7. In forming the closed end one of the flaps 3 is folded inwardly on line 4 and the flaps 5 are then folded down on it and secured with adhesive, the other flap 3 is then folded inwardly on line 4 and secured onto the other flaps. After pushing in the flap 8 pressure applied at 12, causes the container top to arch outwardly in an inverted V-formation. The flap 8 is caused by this action to fold inside the inverted V-formation and to be maintained in such position out of the way of the pouring opening. The flap 8 may have a weakened line down the centre. In a modification the slots 9 are replaced by a continuation of the weakened lines 10, and the flaps 5 are secured beneath the lower flap 3.

Title: Radiation imaging devices
IPC: G01T1/164
Filed: 1971-06-16
Abstract: 1358318 Scintillation camera PICKER CORP 16 June 1971 [19 June 1970] 28270/71 Heading H4F [Also in Division G4] A radiation imaging device includes a detector for resolving scintillations received into analogue electrical signals, these signals then being converted in an analogue digital converter to digital form and stored in predetermined storage channels of a computer from which they are read out to derive for example a visual representation of the stored signals. As described the detector receives incident radiation at a plurality of discrete positions each corresponding to one of the computer storage channels and a coded signal address is produced when either one of the discrete positions receives an incident stimulus to control the feeding of the resulting digital signal into the corresponding storage channel. The storage data which may be fed to a magnetic tape recording console is also fed via a digital/analogue converter comprising parallel weighted resistances switched in under the control of the stored data, to X and Y terminals of two oscilloscopes, a memory oscilloscope and a camera oscilloscope. The image on the camera oscilloscope is recorded on photographic film plate. The camera mechanism includes a shutter solenoid C2 (Fig. 32) which when energized draws a cable C36 around a pulley C40 to rotate shutter plate C26 against the bias of a spring. A colour filter disc C44 having different coloured windows in its four quadrants is mounted on a shaft (C46, Fig. 35, not shown) driven by a stepping motor (C3) so that visual energies representative of scintillation intensities corresponding to the different colours are successively recorded on the photographic plate. Information from the computer is decoded in oscilloscope interface circuitry to control the memory oscilloscope, the camera oscilloscope, the operation of the camera stepping motor and the shutter solenoid.

Title: Method for the preparation of 2-(amino-carboalkoxy-methyl)-4-carboalkoxy-5,5-dimethyl thiazolidine and hydrohalide salts thereof
IPC: C07D277/06
Filed: 1947-10-23
Abstract: Deacylated penicilloic esters of the formula <FORM:0670493/IV (b)/1> (R=alkyl) are obtained as hydrohalide salts by partially hydrolysing their N-formyl derivatives with alcoholic hydrogen halide.  When the alcohol used is not ROH, some ester-interchange may take place.  The starting materials are obtained from N-formyl-glycine esters by treatment with alkyl formate and an alkali alkoxide to give the alkyl derivative of the formamido-glyoxylic ester which is then treated with the mineral acid salt of a penicillamine ester.  For the latter step, the formamidoglyoxylic ester may be condensed with benzylamine to give the Schiff's base which is then reacted with the salt of the penicillamine ester.  The products of the invention when transformed into free bases and treated with a mineral acid salt of a phenacetimino ether give a mixture of G-perillic and G-isoperillic esters.  Examples show the above steps where R is methyl and the acid is hydrochloric throughout.  Ethyl, propyl and butyl esters are also mentioned and the penicillamine ester salt may be a sulphate.

Title: Improvements in or relating to thermally-operated electrical instruments
IPC: H01H37/52
Filed: 1931-10-13
Abstract: 383,017. Thermal switches. ELECTRICAL IMPROVEMENTS, Ltd., Carliol House, and POYNDER, H. B., 14, Haldane Terrace, both in Newcastle-on-Tyne. Oct. 13, 1931, No. 28400. [Class 38 (v).] A thermallyoperated instrument has two bimetallic strips connected together at one end so as to be movable towards or away from each other under the influence of heat, a pointer being pivoted to the free end of one strip and linked to the end of the other strip, so that relative movement of the two ends causes the pointer to move approximately about a centre fixed in space. In the construction shown, two bimetallic strips A, B, each of tapering width, are rigidly attached at their wider ends to the upper end of a metal tube C, the strips-being arranged so that they move apart when heated. Wound around the tube C and insulated therefrom is a heating resistance D connected to the terminals of the instrument and surrounded by heat-insulating packing C3 within a supporting tube C<4>. At their lower ends, the strips A, B carry brackets A<1>, BI to which are attached pins A<2>, B<2>. A pointer F is pivoted on the pin A<2> and has a slot in its end within which the pin B<2> engages. The lower end of the pointer moves over a scale F<1> and carries a pin F<2> which engages a frictionallyheld pointer G indicating the maximum reading. The instrument may be corrected for varying ambient temperature by arranging for the scale F<1> to be moved about the centre of rotation of the pointer by means of another bimetallic strip. The pointer F may be arranged to operate contacts at any. desired point on the scale for controlling an alarm or other circuit. As shown, one or more mercury switches J, connected by flexible leads to terminals J<2>, are carried by a freely suspended metal frame H which also carries a curved rod H<3> normally abutting against a fixed stop E<4>. The rod H<3> has clamped to it a block H<4> having a projection which lies in the path of the pin F<2> on the pointer F and may have an index mark to indicate on the scale F<1> the scale reading at which the switch contacts are opened. According to the Provisional Specification, the pointer may be pivoted to one end of a bimetallic strip and linked to the other end of the same strip.

Title: Improvements in or relating to radio direction finders
Inventor: MOON JAMES HARDWICKE
IPC: G01S3/42
Filed: 1951-12-04
Abstract: 729,309. Radio direction-finding. MARCONI'S WIRELESS TELEGRAPH CO., Ltd. Aug. 7, 1952 [Dec. 4, 1951], No. 28434/51. Class 40 (7). A direction-finding system comprises a directional aerial, for example a loop, means for producing azimuthal variation in its directivity, a ferromagnetic core within the aerial the real or effective positioning of which may be periodically varied to give a zenithal variation of the directivity and so modulate the received signals, and means for comparing in phase the modulation produced with a reference voltage synchronized with the periodic variation. In a first embodiment the loop aerial 1 is mounted on a column 2 which may be rotated by motor 3 and which carries a bearing indicating scale 5 co-operating with a fixed pointer 6. Mounted obliquely on a spindle 10 passing concentrically through the loop 1 is a high permeability iron core 11. Spindle 10 is rotated by motor 12 and also carries A.C. generator 13 providing the reference signal which is fed to motor 3. The loop aerial output is fed through slip rings 14 to receiver 15 and the modulation signal obtained amplified at 18 and also fed to motor 3 which effectively serves to phase compare the two inputs and automatically aligns the aerial loop and column 2. An open aerial 16 and switch 17 is used initially 'to ensure that the loop aligns itself in the correctly sensed position and thereafter the position is maintained in accordance with loop aerial signals only. In a modification (the Complete Specification Figure, not shown) three symmetrically located oblique iron cores are arranged through the loop and pairs of these are saturated in circular sequence by coils energized through a distributer to provide an equivalent to the moving core of Fig. 1 without the necessity of having to move parts of the aerial arrangement.

Abstract: 957,602. Mixing powders and gases in proportions. W. E. STANTON, and V. J. COPAS Ltd. Nov. 21, 1960 [Aug. 20, 1959], No. 28441/59. Heading B1C. In a method of supplying a constant ratio mixture of powder and gas the powder is contained in a flexible bag 14 enclosed in a container 10 having a movable bottom or piston 12, and the gas is directed in a jet 51 at the powder surface forming a crater 53. Powder is taken into suspension in the gas in the mixing chamber 17 and is discharged through the pipe 22. The powder surface is maintained in contact with the top 11 of the container and hence at a constant distance from the gas nozzle 19 by means of the tension of the springs 23 and the weight of the container, which move the latter downwards over the movable bottom 12. Alternatively the container may be fixed and the bottom urged upwards thereinto. The ratio of powder to gas may be altered by adjusting the intrusion of the nozzle 19 into the mixing chamber 17.

Filed: 1960-08-17
Abstract: 921,888. Phase-sensitive circuits. CURTISSWRIGHT CORPORATION. Aug. 17, 1960 [Aug. 27, 1959], No. 28555/60. Class 38 (4). [Also in Groups XXXVI and XL (c)] In a non-linear circuit for alternating signals the signals are fed to the input of an amplifier A via a conductance g 1 , and also via conductances g 2  and first and second diodes 22, 24, respectively, the cathode of the first diode 22 and anode of the second 24 being connected to the input of the amplifier. To the anode of the first diode 22 and cathode of the second 24 there are applied via conductances g 4 , respectivley negative and positive-going full-wave rectified bias signals derived from a voltage of the same waveform as the input signal via transformer 32 and full-wave rectifying network 36, 38, 40, 42, the bias signals being in synchronism with the input signals. The diodes 22, 24 are biased to the bend in their characteristic by means of a D.C. bias applied over conductances g 3 . Negative feed-back is applied to the amplifier by means of conductance g 0 . It is shown in the Specification that various non-linear characteristics (Figs. 1A-1G, not shown) can be obtained according to the relative values given to, or omission of, the conductances g 1 , g 2 , g 3 , g 4 . The response is unchanged if the phase of the input signal is reversed but may be made unsymmetrical by omission of the rectifiers 40, 42. In a modification (Fig. 2, not shown) the diodes 22, 24, conductances g 2  and associated biasing network are placed in the negative feed-back path of the amplifier. Further characteristics may be obtained by opposing to the amplifier output that of a parallel-fed linear amplifier, which in the limit may comprise a resistor (Fig. 3, not shown). This latter arrangement may be modified (Fig. 4, not shown) to give an arrangement of which the output is linear with respect to the input signal but whose sign is the same whether the input signal is in phase or antiphase, but in which quadrature signals are rejected.

Title: Improvements relating to motors for electric meters
IPC: G01R11/36
Filed: 1932-10-13
Abstract: 408,935. Supply meters; power meters. MARTIN, A. J., 5, Milton Crescent, Ilford, Essex. Oct. 13, 1932, No. 28603. [Class 37.] In an induction disc driving motor for indicating and integrating watt meters having the potential core 1 mounted between two current cores 10, the line joining the centres of the polepieces of these cores being perpendicular to a radius of the disc 21, a limb 2 of the potential core is closely adjacent to one face of the disc leaving room for the current winding or windings on a part of the current cores more remote from the disc and a limb 11 of each of the current cores is closely adjacent the other face of the disc 21 leaving room for the potential winding on a part of the potential core more remote from this other face of the disc. The cores are formed with enlarged pole -pieces adjacent the disc and are bolted together by non-magnetic bolts 18, distance pieces 20 separating the adjacent faces of the cores. The poles of the current cores are provided with overload bridges 22 and a similar overload bridge 23 consisting of a strip of magnetic material is provided for the potential magnet. To ensure a good contact of large area the ends of the strip 23 are bent round the ends of a non-magnetic strip 24 which wedges them into depressions formed in the limb 4 and pole-piece 8 respectively. Other forms of bridge and modified core shapes may, however, be employed, Figs. 3 and 4 (not shown). Instead of each current core carrying a separate winding a common winding embracing both cores may be employed. Plates of non-magnetic but high conductivity material may be placed between the cores and outside the assembly for the purpose of concentrating the fluxes by reason of the induced eddy currents where such concentration is desired.

Title: Combined synchronizing pulse separator and direct current reinsertion circuit
IPC: H04N5/18
Filed: 1953-10-16
Abstract: 733,294. Televisioncopying telegraphy. RADIO CORPORATION OF AMERICA. Oct. 16, 1953 [Nov. 8, 1952], No. 28647/53. Class 40 (3). [Also in Group XL (c)] A single transistor is employed in a television or facsimile transmission system to reinsert the D.C. component in the image signal and also to separate out the synchronizing impulses from the image information. In Fig. 1, the base emitter path of a P-N-P junction transistor 27 is connected between the transmission path and a point of reference potential, earth as earth as shown, and functions as a conventional D.C. restorer to stabilize the image signal 12 with the peaks of the synchronizing pulses 12a just negative of the reference potential. During the image portions of the signal when the base 33 is driven positive with respect to the emitter 31 and the base-emitter path present a high impedance, only a small current flows to the collector 35, but during the synchronizing impulses when the base-emitterpath presents a low impedance, an increased current flows to the collector resulting in corresponding impulses 42a across collector resistor 37. Impulses 42a may be of increased amplitude due to the amplifying action of the transistor in the base input arrangement. In a typical television receiver, Fig. 2 (not shown), terminals A, A feed a conventional synchronizing signal separator supplying outputs to line and frame scanning generators. An N-P-N junction transistor may be employed in an emitter input arrangement, i.e. with the emitter connected to the transmission path and the base connected to the reference potential. With image signals of reverse polarity such that the synchronizing signals extend in a positive direction, an N-P-N transistor is employed connected in the base input arrangement or a P-N-P transistor connected in the emitter input arrangement. Point contact transistors may be employed in place of junction transistors.
