Title: Improvements in or relating to selective amplifiers particularly suitable for wireless reception
IPC: H03H7/01
Filed: 1928-01-03
Abstract: 314,884. Marks, E. C. R., (Vreeland Corporation). Jan. 3, 1928. Thermionic amplifiers. - A multistage valve set is designed to give a selective and substantially-uniform amplification over a definite narrow band of frequencies, with a sharp cutoff outside this band, the arrangement being such that the selective limits of the circuits can be varied up and down a wide frequency-range. The frequency-amplification characteristics of successive stages may vary from valve to valve, as shown in the curves 1, 2, 3 of group A in Fig. 4, so long as the overall amplification results in a flat-topped curve 4 with a sharp cut-off. The curves of groups B and C show similar frequency-amplification characteristics at different points in the frequency scale. This effect is secured by utilizing coupling transformers T, Fig. 1, in which both primary and secondary coils p, s comprise reversely-wound portions in combinations with fixed shunt condensers 10 and variable band-shifting condensers 8 ganged together on a common control spindle. The inductance values of the transformer windings, their inherent capacity represented by the capacity C, and the parallel capacities 10, 8 together determine the band amplificationcharacteristic of each stage, whilst the ganged condensers 8 are utilized to shift the selected band of amplification up and down the frequency scale. The capacity values of the condensers 10 may be fixed or graded from stage to stage, or this variation may be introduced by means of the ganged condensers 8, through the flexible couplings 12. The condensers 10 may be inserted in parallel with either the primary or secondary windings of the transformers instead of bridging both as shown in Fig. 1. Alternatively, inductance elements may be added to the transformer windings in place of the condensers 10. The loosely-coupled input circuits L1, CA, C1 and L2, Cx, C2 are similarly designed to have a bandamplification characteristic, the band being shifted to any desired part of the frequency scale, simultaneously with the setting of the intervalve couplings, by means of the tuning or control condensers 8. Local disturbances external to the set are minimized by the astatic windings of the transformers T. Specification 294,939 is referred to. Reference has been directed by the Comptroller to Specifications 147,853 and 198,052.

Title: Improvements in and relating to saddles for motor cycles
IPC: B62J1/02

Abstract: 605,670. Saddles for motor cycles. BIRMINGHAM SMALL ARMS CO., Ltd., POPPE, E., and NEEDHAM, V. E. Jan. 3, 1946, No. 219. [Class 136 (iii)] [Also in Group XXXII] In spring supports for saddles of the kind in which the peak is pivoted to the cycle frame, while the cantle is supported by one or more springs, a coiled spring is housed within the top tube of the cycle frame, one end of the spring being held relatively to the top tube and the other end being operatively connected to link mechanism acting between the spring and the cantle part. The spring 49, Fig. 1, is disposed within a sleeve 50 which is housed within the top tube 19 and has the end 51 flanged outwardly to bear on the end of the tube and the end 52 flanged inwardly to engage a ring 53 against which one end of the spring bears. The other end of the spring bears against a cylindrical member 48 which is slidably mounted in the tube and is formed with a depression to receive the hemispherical end 47 of an arm 46. An extension 55 of the member 48 extends into a tube 54 which is disposed within the spring and contains an oil wick 57. Oil passes from the wick to lubricate the spring through apertures in the tube and through a passage 56 to lubricate the member 47. A tubular lug 45 formed integral with the arm 46 is pivoted on a pin 44 which connects the arms 43 of a pair of bell-crank levers 38. These levers and a pair of links 21, Fig. 2, are pivoted on a pin 22 which is carried by lugs 24 extending from the part 18 of the frame. Stops 59 integral with the lugs 24 co-operate with lugs 48 on the arms 43 to restrict the upward movement of the cantle part. The arms 37 of the levers 38 are connected by a tube 42 which surrounds a pin 41. The ends of the pin are inserted in any opposite pair of a series of holes 40 formed in the links 21. A tube 25 secured rigidly to the links 21 carries a pivot pin 26, Fig. 3, the ends of which are threaded and carry between nuts 28 a disc 29. Hollow bushes 33 of rubber or like material are bonded to the disc and to side plates 31 which are supported by a pin 34 mounted in a lug 36 depending from the cantle plate 10. A lug 17 integral with the part 18 houses a cylindrical rubber bush 16 which surrounds a sleeve 15. This sleeve receives a pivot pin 14 which connects the side members 11 of the saddle.

Abstract: 1,208,692. Wrappers for cigarettes &c. REYNOLDS METALS CO. 2 Jan., 1968 [16 Jan., 1967], No. 317/68. Heading A2C. Wrapper material for cigarettes, cigarillos or small cigars comprises porous combustible sheet material such as paper, tobacco leaves or reconstituted tobacco sheet, having a metal (e.g. aluminium or aluminium alloy) coating thereon which is not so thick as to impair the porosity or combustibility of the material but which on combustion yields an ash which is less permeable than the uncoated material, the coating being applied to one or both sides of the material to a total thickness amounting to not less than 0.5 micrograms of metal per square millimeter. The effect of the coating is to increase the peak combustion temperature of the burning tobacco in the wrapped smoking article.

Title: Improvements in or relating to circuits for repeating square shaped wave forms
IPC: H03K5/02
Filed: 1944-01-15
Abstract: 581,011. Valve amplifying circuits. STANDARD TELEPHONES & CABLES, Ltd., and GLOVER, W. F. Jan. 15, 1944, No. 817. [Class 40 (v)] In a pulse amplifier, the iron cored output transformer has a primary, a secondary and a bias winding, the last being fed by a steady current so that its flux opposes the flux produced by the pulse, so that the whole range of the hysteresis loop of the core may be utilized to enable the amplitude of the pulse to be increased. Fig. 1 shows a two-valve amplifier with the output transformer T in the cathode of V2 feeding the load R2. The biassing coil 5, 6 fed by the steady current from the decoupled cathode of valve V1 produces flux opposite to that produced by pulse current in coil 1, 2. The core of the transformer T thus becomes saturated by the pulse much later than if the bias current were absent, so per-. mitting a larger pulse amplitude. The transformer T may also be in the anode of V2 and the bias coil fed from any other suitable electrode.

A small-diameter tube 13 is provided on the outside of the spring 12 so as to cover the spring 12 to smooth the contact area with a coolant and to decrease pressure drop. Further, a solid rod 14 is provided in the spring 12 to improve the joining to the tie plate 7 and mechanical strength. On the other hand, the spring force of the expansion springs 11A of the fuel rods 2 can be decreased and, therefore, the space A for absorbing the axial expansion difference between the fuel rods 2 can be widened by a decrease of the number of turns, etc. An increase of the length of the fuel rods 2 by decreasing the assembly length is possible as well.

IPC: C12N9/28
Filed: 1981-01-06
Abstract: A recombinant bacteriophage, a method for producing and selecting the recombinant bacteriophage and a method for heterologous cloning of DNA are disclosed. The recombinant bacteriophage is produced by ligating genetic fragments encoding a desired genetic trait with DNA from a bacteriophage, incubating with DNA from a second Bacillus microorganism prototrophic for a growth requirement, incubating with a host Bacillus auxotrophic for the growth requirement. Transformed host Bacillus are selected by growing the mixture on a growth medium which does not contain the growth requirement and determining the presence of the genetic trait. The recombinant bacteriophage containing the desired genetic trait is recovered from the host Bacillus by induction. Heterologous cloning can be accomplished by incubating a host Bacillus with the recombinant bacteriophage.
