Title: Mechanical pyrethrum picker
IPC: A01D45/00
Filed: 1955-07-19
Abstract: 796,351. Gathering flowers. BASKETT, R. Feb. 28, 1956 [July 19, 1955], No. 20836/55. Class 6(3). A flower picking apparatus comprises a casing 1 movable over the crop and open only at its lower part 14, a perforated drum 6 being rotatable about a horizontal axis within the casing at a circumferential speed equal to the translatory speed of the casing, a fan 2 being rotatable within the drum to cause flower-heads to adhere by suction to its perforated surface and to be carried around by it, after severance by a fixed knife 16, to a point where the suction is cut off by a baffle 17 within the drum whereby the flower-heads are released. The drum is driven by a land-wheel 12 through a belt 9 and the fan is driven by a belt 4 from the towing tractor (not shown). Crop guides 15 project in front of the casing to raise the flower-heads.
Patent GB-781524-A (GB)
Title: Improvements in or relating to therapeutic compositions for the treatment of mastitis
IPC: A61K31/65
Filed: 1955-07-19
Abstract: A composition effective against mastitis comprises calcium dioxytetracycline in an aqueous vehicle containing a non-toxic alkaline earth metal (including magnesium) alginate as a thickening agent and a pharmaceutically acceptable suspending agent.  The alginate thickening agent may be prepared in situ by reacting sodium alginate with alkaline earth metal salts of hydroxy carboxylic acids of low molecular weight and low toxicity such as calcium lactate, magnesium lactate and calcium tartrate. Specified suspending agents include polyoxymethylene derivatives of fatty acid esters of anhydro sugar alcohols such as sorbitan. Stabilizing agents such as sodium bisulphite and sodium formaldehyde sulphoxylate and germicides such as parahydroxybenzoic acid esters, phenol and benzyl alcohol may also be present.  The compositions may also include polymyxin in minor proportion.  The preparation is preferably prepared by forming an aqueous suspension of the alginate thickening agent, adding the suspending agent and stabilizers, and homogenizing.  A small quantity of this is added the antibiotic or antibiotics, and the germicides, and the remainder gradually stirred in and the preparation again homogenized.  In an example, a preparation comprising calcium lactate, sodium alginate, a suspending agent, sodium bisulphite, calcium dioxytetracycline, polymyxin B sulphate, methyl p-hydroxy benzoate and propyl p-hydroxy benzoate is described.  Specification 732,751 is referred to.

Abstract: 1504893 Fluid-blast interrupter WESTING- HOUSE ELECTRIC CORP 19 May 1975 [20 May 1974] 21157/75 Heading H1N A fluid-blast circuit interrupter has provision for varying the sequence of movements of the current-interrupting and arc-extinguishing components by arranging them to be separately movable and actuated by a variable cam device. The fixed and moving arc-carrying contacts 32 and 30 respectively are bridged, when closed, by a conductive sleeve 34 which carries the steady-state current and is slidable on the movable contact 30. Extinguishing gas is supplied to the chamber 10 but is excluded from the contact area by the nozzle mouths 18, 24 which have a gasket 28 and act as a valve in the closed position. Rigid links connect the movable contact 30, steady-state contact sleeve 34, and movable nozzle 22 via pins 56 to a cam having contoured grooves 40, 42, 44 which determine the sequence and timing of the opening movements of the aforesaid movable members. Thus the point at which the nozzle mouths 18, 24 part to introduce a blast of gas to the arcing zone may be altered relative to both the length of arc and its duration. Preferred dimensions for the nozzle geometry are given.

The work rolls 7 and 8 in a four-high roll stand are balanced by means of hollow pistons 12 moving in bores in the backing roll chocks 3 and 4. The pistons 12 each have a projection 13 engaging in a recess 9 in a work roll chock so that movement of the pistons urges the work rolls towards or away from one another. Movement of the pistons 12 is controlled by fluid pressure which is introduced to one or other side of counter-pistons 15, slidable in the pistons 12 and fixed to the chocks 3 and 4. Passages 17 and 18, passing through the stem 16 of each counter-piston 15, serve to convey pressure fluid. According to whether the end of the work rolls are urged towards or away from one another, the rolls exhibit a concave or convex profile towards the opposite roll.

Title: Improvements in and relating to integrating mechanism for meters
IPC: G01F1/37
Filed: 1926-08-31
Abstract: 266,616. James, R. W., (Brown Instrument Co.). Aug. 31, 1926. Integrating.-In mechanism wherein a control element associated with the indicating pointer determines the extent of movement of a counting mechanism controlled by a motor or other driving means the actuating mechanism of the counter is retained by a latching means out of engagement with the driving means and is released to permit of engagement at an interval following each latching dependent on the position of the control element. As shown in Fig. 1 applied to a fluid flow meter as described in Specification 279,977, [Class 106 (ii), Dynamometers &c.], a magnetic core e of a pair of solenoids f, f<1> receives movements in accordance with the rate of flow and transmits the same through a lever K and link to an arm H<1> on the shaft H of the indicating pointer I and recording arm J<3>. The shaft H carries a control arm S formed as a flat flexible blade, the position of which determines the amount of rotary movement imparted to a disc U controlling the actua tion of a counting mechanism X. The disc U is journaled in an arm T pivoted at G<2> and is moved into and out of engagement with a constantly rotating cam disc M<1> driven by a timing motor L by means of a lever P pivoted at G<1> and oscillated by a link O connected to a crank pin M<2> on the disc M<1>. On the pivot G<1> is supported a tripping member Q which co-operates with a latch R pivoted at P<1> to the lever P and provided with a pin R<1> working in a slot in the arm T. On the downward movement of the lever P the parts Q, R remain interlocked until the end Q<3> of the member Q strikes the control arm S whereupon the latch R is released and the disc U engages the raised part m of the disc M<1>. A roller P<2> on the lever P at the same time engages the arm S to prevent it being displaced. The disc U through worm gearing drives a shaft W having an arm W<1> actuating the counter X. In a modification shown in Fig. 8, the shaft W carries the lowest counting wheel W<4> and each revolution of the shaft is transmitted to the counting mechanism X by a power driven shaft Z. This shaft has secured thereto a ratchet wheel Z<1> and loosely mounted thereon a cam disc Z<2>. A spring controlled pawl Z<3> pivoted to the cam disc is held free of the teeth of the ratchet wheel by a plate W<2> on the shaft W until a peripheral notch W<3>. Fig. 10 thereon permits the pawl to engage the ratchet teeth whereby the cam rotates for one revolution so as to rock a lever Y actuating through a link Y<1> the counter X. A spring controlled arm Z<6> is provided to give the cam disc a sudden movement to disengage the pawl Z<3>. The wheel W<4> is connected to the shaft W by means of a. spring W<5> and an arm on the wheel co-operates with a stop proiection X<3> on the actuating arm X<1> to ensure that the arm X<1> is actuated before the wheel W<4> reaches its zero position. In a. further modification the arm Y may be dispensed with and the arm Z<6> be utilized to actuate the counter arm X<1>.
