Title: An improved means for feeding tobacco leaves to tobacco stripping machines
IPC: A24B5/12
Filed: 1926-08-03
Abstract: 278,129. Phillips, M. G. P. Aug. 3, 1926. Tobacco.-Forwarding and re-arranging mechanism for stripping-machines comprises rollers 6 mounted on spindles 7 and driven from an electric motor 5. Between the rollers, bars 13 are supported on uprights 14 and are lifted and reciprocated by means of a crank connection to shafts 18, 18a, one of which is geared to the motor shaft. Also protruding between and partly embracing the rollers 6 are fixed members 22. As the leaves are lifted and forwarded by the bars 13 the rollers 6 and members 22 have the effect of re-arranging them with their butt ends in one direction, transverse movement being limited by the fence 21. Discharge takes place over the edge of an upstanding portion 24a of a plate 24 and thence to the feed belt w of a, stripping machine. The plate 24 is slotted for the passage of the ends of the bars 13. The loosely bundled leaves are placed in a hopper consisting of side plates 29, 30, and two series of downwardly inclined bars 26, 26a between which move extensions of the bars 13; these extension members 13a, 13c, 13e are hinged about spindles 13b, 13d. The inner surfaces of both fixed and movable hopper members may be roughened or otherwise treated to assist the tumbling action of the leaves, and projections may also be formed to prevent backward movement. The line of each set of bars may be inclined so that the hopper at one end is narrower than at the other. Modifications are indicated in which belts, cords, or elastic members may replace the fixed members 22; the rollers 6 may be elliptical, in which case the bars 13 or their equivalents may receive a reciprocating motion only with no up-and-down movement. The fence 21 may be movable to avoid any drag on the leaves.

Title: Improvements in or relating to a method of inoculating a liquid culture medium with mould spores
IPC: C12N3/00
Filed: 1945-07-27
Abstract: A method of inoculating a liquid culture medium with mould spores, comprises growing the spores on a sterile moist cereal-bran nutrient substratum and dispensing the resultant spore-bearing mass on the surface of the nutrient medium.  The substratum may be obtained by grinding whole grain cereal brans of maize, barley, rye, or wheat to pass a 16/64 in. screen and adding optionally oat hulls or coarse grain together with wheat flour, glycerine, molasses, distillery slop, peptone, and inorganic salts such as sodium chloride, magnesium sulphate, potassium phosphate and sulphates and chloride of iron and copper. The substratum is sterilized and incubated at 22 to 27 DEG C. for Penicillium notatum and Aspergillus flavus, 30 DEG C. for Aspergillus niger, and 35 DEG C. for Rhizopus oryzae.  Before inoculuting fresh culture medium the substratum is preferably mixed with floating agents such as finely ground oat hulls, wheat bran, wheat flour, soya bean hulls, sawdust, talc or cork to assist distribution.

Title: Improvements in or relating to actuating mechanism for implements attached to tractors
IPC: A01D76/00
Filed: 1950-08-02
Abstract: 694,048. Hay-rakes. BUTLER, J. A., and GLIDDON, A. D. S. Oct. 22, 1951 [Aug. 2, 1950; May 21, 1951], Nos. 19320/50 and 11841/51. Class 6(iii) A tractor-mounted hay-rake has a tineframe 11 raisable by hydraulic power derived from the tractor through a ram unit 27 acting on a lost motion, or a toggle, linkage 20, 21, the arrangement being such that the tines are raised and lowered during a single stroke of the ram and the return stroke of the ram occurs without displacement of the tines. The tines 10 cooperate, on raising, with clearing tines 18 secured to the main frame 13 which is mounted on the triple links 14, 15 of the tractor. The tine-frame 11 is pivoted to the frame 13 at 12 and is connected to a knee-action strut 20, 21 which is substan-' tially straight when the tines are lowered. 'The part 21 of the strut is pivoted at 33 to a link 32 having a longitudinal slot 31 terminating in a notch 34 which houses a pivot-pin 30 carried by a pivoted link 25 raised and lowered by the ram 27. A bellcrank 36, 37 is pivoted to a fixed point 35 on the frame and has one arm slidably restrained within a stirrup 39 on the part 21. Application of pressure-fluid to the ram raises the links 25 and 32 thereby forcing the toggle 20, 21 and the tines 10 into the dotted positions of Fig. 1. Continued movement of the ram causes a pin 40 to engage the hooked arm 37 of the bellcrank thereby straightening the toggle 20, 21, and returning the tines to operative position. A spring 29 returns the ram to its original position upon release of the pressure. In a modification, Fig. 5, a ram 48 rotates an arm 42 through a cable 47 and pulley 46 the arm having a cranked slot 44 which carries a pin 45 at the end of a rod 41 connected to the tine-frame 11. The arm 42 also carries a pin 56 which unlatches a locking mechanism 52, 54 as motion of the ram commences, thus per-' mitting the tine-frame to swing. When the arm 42 passes over dead-centre, the pin 45 slides idly along the slot 44.

Title: Hydraulic drive for reciprocatory conveyor equipment
IPC: B23Q11/00
Filed: 1958-06-18
Abstract: 867,144. Step-by-step conveyers. WISSMANN, K. June 18, 1958 [June 28, 1957], No. 19509/58. Class 78 (1). The hydraulic cylinder drive 1 for a reciprocating conveyer for swarf of the type comprising a pusher member 9 working in a trough 4 is controlled by means which bring it to rest for a period after each stroke and reverse it at the end of this period. The piston 20 of the cylinder 1 has a bore 21 with valve seatings 22, 23. Valves 24, 25 slide in the bore and their spindles project from the piston when a valve is seated. Towards the end of the movement of the piston to the right, the spindle of valve 25 meets an adjustable stop, or the end of the cylinder, and this valve is opened. Since the spindles are formed with grooves, fluid can now pass from one side of the piston to the other and the piston comes to rest and remains stationary until an hydraulic or electric time-switch causes a flow of fluid in the opposite direction to close the valve 24 and move the piston to the left. If the piston meets an obstruction, which it cannot overcome, during its stroke, it stops, but the pump continues to work against the safety-valve which continues to blow until the time switch reverses the direction of movement.

IPC: H04M17/02
Filed: 1921-07-21
Abstract: 187,689. Huntsworth, G. H., and Anderson. T. G. July 21, 1921. Hiring telephones; coin action, electric-connection and multiple-coin.-In a prepayment telephone. call apparatus, Figs 4, 5 and 6, which is adapted for calls of any value from one penny to sixpence and in which the sum can be made up in every possible way frorn six pennies and seven half-pennies, there are two pairs of inclined coin guides for pennies and half-pennies respectively, leading from insertion slots a<4>, a<5> to a cash box b, each pair comprising longitudinally grooved members, which are divided into sections separated by insulation c or air gaps. The sec. tions are connected to a series of contacts adapted to be bridged by pieces g<5>, g<6>, g<7>, on a switch arm g<1>. The circuit is completed through two contact bars 1<b>, s<1>, the contacts, the bridge pieces g<5>, g<6>, g<7>, the coin slide sections and the coins, a lamp f on the pay box being illumined each time the circuit is made. On the outside of the box there may be an indicator scale, Fig. 5, shewing the various sums which can be paid, and denoting the position to which a pointer g' secured to the spindle of the arm g<1> must be turned to complete the several circuits. When the receiver is lifted, the contact bar 1<b>, which is connected to the line through a tubular indicator T of any standard type and the lamp f, be. comes potentially alive and the telephone instrument circuit is made through a lead 1<c>, bridge piece g<7>, contact pieces 1<d>, s<3>, contact bar s<1> and leads s, 2, the switch arm being in its normal position. At the same time solenoids e are energized to attract the arms d<1> of counterweighted levers d, d<1> causing them to close the lower ends of the coin slides. When the receiver is replaced the levers move to the position shown in dotted lines, Fig. 4, and the coins are discharged into a cash 'box b. The vallue of the coins inserted is signalled to the exchange as follows. Each time the telephone instrument circuit is broken, a lamp on the operator's board glows so that, as the switch arm g<1> moves from its normal position over the contacts of the switch frcm the sixpenny to the penny division, a, series of long and short signals. is given. The arm moves over a series of contacts l<1> - - l<10>, placed between the switch divisions and operating through a lead l, to energize an electromagnet L which resets the indicator T. The discharge ends of the coin slides may be controlled mechanically, the levers d, d<1> being connected through links d<14>, d<6>, Fig. 9, to handles d<4>. A shutter d<11> pivoted on a rod connecting the pair of handles closes the coin slots when the discharge, ends of the coin guides are open. When the switch arm g' returns to its normal position it actuates the links d<14>, d<6> through a bell crank d<20>, d<19> to discharge the coins. By providing a second scale and pointer and further coin guides with suitable connections the apparatus may be adapted to take silver as well as copper coins.

Title: Improvements in and relating to electric circuits for modifying frequency response in amplifiers and the like
IPC: H03F1/50
Filed: 1935-07-09
Abstract: 459,526. Valve amplifying circuits; impedance networks. HARDWICK, J., 21, Drayton Park Avenue, West Drayton, and WHITE, E. L. C., 32, The Rise, Hilling- don, both in Middlesex. July 9, 1935, No. 19646. [Classes 40 (iii) and 40 (v)] An amplifier or other circuit is designed tc produce a desired frequency - response correction in two stages, whilst the respective stages have opposite phase-shifting effects so that phase distortion is avoided. As shown in Fig. 1, the first stage of frequency discrimination (in favour of high frequencies) is effected by a coil 7 in series with the anode resistance 8 of a first valve 3. The second stage, also favouring high frequencies, comprises a transformer 12 in series with the anode resistance 13 of the second valve 4 the output being taken from across the resistance 13 and the secondary coil of the transformer 12. In the modification shown in Fig. 2, a single valve 15 is used, and one frequency-discriminating network comprising a resistance 19 shunted bv a condenser 20 is inserted in the cathode lead whilst the other network comprising a transformer 12, and resistance 13 is in the anode lead. The output is taken off as in Fig. 1. A limiting resistance 21 may be connected across the primary coil of the transformer 12 or across both that element and the resistance 13. The Specification indicates the necessary relations between the electrical values of the elements 7, 8, 12, 13 of Fig. 1 or the elements 12, 13, 19, 20 in order that phase distortion may be avoided, whilst permitting a frequency discrimination in favour of the higher frequencies. Such discrimination is necessary to correct the fall in response at high frequencies due to the finite size of the scanning spot or aperture in a television system.
