Title: A combined weighing and vending machine
IPC: G07F17/04
Filed: 1930-09-13
Abstract: 362,989. Coin - freed weighing and article delivery apparatus. SALTER & CO., Ltd., G. and ROGERS, E. R., 144, High Street, West Bromwich. Sept. 13, 1930, No. 27359. [Classes 27 and 143.] In a mechanically - operated coin-freed weighing and vending machine in which the weighing mechanism and vending mechanism are self-contained and separate from one another and are so disposed that they may be successively operated by the same coin, the weighing mechanism comprises an angularly-movable arm carrying a coin receptacle or holder, the coin first falling into the latter and actuating the arm and then dropping into a shoot leading to the vending mechanism. Articles stored in piles ; coin action, weight and mechanical connection.-The two mechanisms are contained in a vertical casing 1 surmounted by a weight-indicating dial. An inserted coin passes down a shoot 19, Fig. 8, to a receptacle 18 and after actuating a lever 16, toothed sector 15 and indicator pinion 14 to indicate the weight of the load, falls down a shoot 22, Fig. 5, and is deflected by a throw-over switch 24 to one or other of two branch shoots 23a, 23b each leading to a common operating slide 26 which may be pulled forward along guide-bars 27, by an external knob 28a, Fig. 2, and retracted by a spring 29. Above the operating slide are two ejector slides 34 arranged near the bottom of two packet magazines 36. After passing down a branch shoot, the coin is received in a vertical slot in the operating slide and rests with its lower edge on a stepped bracket 31. When the knob 28a is pulled out the slide 26 carries the upper edge of the coin against the corresponding ejector slide which is then pushed forward to eject the lowermost packet and deliver it down a shoot 37, the coin then falling from the stepped bracket 31 into a collecting receptacle 38. The slide 26 on returning carries back the ejector slide. A gravity catch, liberated by the initial movement of an ejector slide, locks the slide 26 in its rearward position. Empty machines, locking.-When the last packet in the magazine has been delivered, a loose pin carried by a weight resting on the pile of packets, drops into a hole in the ejector slide and prevents the knob 28a from being pushed in again. In this condition, weighing only is permissible, the coins being diverted from the vending mechanism by a throw-over flap 69, Fig. 5, operated by an arm 60 (positioned by the inoperative vending slide), spring- pressed lever 64 and rod 67, and the coins then pass down a shoot 71 leading directly to the collecting receptacle 38. "Empty" notices, displaying.-In assuming the outermost position, the operating slide 26 permits a lever 57, 59, 60 to turn under the influence of a spring 56 and cause an indicator 46 to notify the operator that the machine no longer weighs and vends but weighs only.

Title: Amine salts of herbicidal organic acids
Inventor: FURNESS WALTER
IPC: A01N39/02
Filed: 1965-06-29
Abstract: 1,148,387. Amine salts of herbicidal organic acids. FARM PROTECTION Ltd. 29 June, 1966 [29 June, 1965], No. 27379/65. Heading C2C. [Also in Division A5] The invention comprises salts of 2-methoxy- 3,6-dichlorobenzoic acid (dicamba) with an aliphatic amine containing at least 8 carbon atoms. The amine is preferably one of the general formula R.NA[(CH 2 ) y NA] x A, where R is an aliphatic hydrocarbon chain of from 8 to 21 carbon atoms or a mixture of such chains, the nitrogen atom being linked to the alpha or beta carbon atom when R is an unbranched chain, y is 2, 3 or 4, is 1 or 2, A is a hydrogen atom or the group (C 2 H 4 O) n H, in which n is an integer from 1 to 5 or (C 3 H 7 O) m H in which m is an integer from 1 to 4. Specially preferred amines are those of the type (a) RNHC 3 H 6 NH 2 , wherein R is a mixture of C 16  and C 18  chains such as are found in oleic acid or a hydrocarbon chain derived from coconut oil, (b) where p+q+r is statistically equal to 3 and R is a hydrocarbon radical derived from tallow acids, and (c) RCH(CH 3 )NH(CH 2 ) x NH 2  wherein x is 3 and R is a straight chain aliphatic hydrocarbon radical having 15 carbon atoms. Other aliphatic amines having at least 8 carbon atoms which may be used include primary, secondary and tertiary mono-amines, ethoxylated amines and amines having an amino group on a betacarbon atom. In preparing the salts it is preferred to use enough acid to react with each nitrogen atom of the amine (when more than one nitrogen is present) and reaction is normally effected by warming a mixture of the amine and acid or by adding the acid gradually to a solution of the amine in a hydrocarbon solvent and allowing the temperature to rise, e.g. up to 70‹ C. The dicamba salts have herbicidal properties and may be used alone or in admixture with salts of aliphatic amines having at least 8 carbon atoms with 4-chloro-2-methylphenoxyacetic acid (MCPA) or the corresponding 2-propionic acid (mecoprop) or -4-butyric acid (MCPB), 4-chloro-phenoxyacetic acid (4- CPA) or 2,3,6-trichlorobenzoic acid (2,3,6-TBA).

Title: Improvements in the control of gas lights for beacons and the like
IPC: F16K31/48
Filed: 1954-09-24
Abstract: 752,428. Visible signalling apparatus. ETABLISSEMENTS H. LEPAUTE. Sept. 24, 1954 [Sept. 25, 1953], No. 27628/54. Class 118(2) An occulting device for gas lights of beacons and the like comprises a mechanical movement driven by a spring which is rewound automatically by the gas serving to feed the burner. To avoid leakages and frictional losses due to stuffing boxes the mechanical movement operates in the gas at the pressure for feeding the burner. A spring-driven mechanism M of any known type operates within an enclosure A through which gas passes to the burner (not shown) via a valve I controlled by the mechanism M. A diaphragm or piston B is coupled to a pawl G on its upper side and to a rocker valve C on its underside. The piston B moves in enclosure A to operate the valve C only at each end of its stroke I by virtue of a sudden-action device E. A spring Fr is provided to return the piston B from the position shown in Fig. 2 to the position indicated by a broken line, expelling gas via one side of valve C to the reducing valve D 2  and enclosure A. When piston B reaches its lower position valve C suddenly rocks to close the outlet to valve D 2  and open the inlet from valve D 1 . Gas at a relatively high pressure then forces piston B upwards causing pawl G to wind the driving spring R of mechanism M. At the top of its stroke piston B causes valve C to change-over and the cycle repeats. A pawl H prevents the spring R unwinding when the piston B descends and a known frictional device or means for disengaging the pawl G is provided to avoid locking the piston when the spring R is fully wound. In a modification (Fig. 3, not shown) an extra valve controlling a passage connecting the two sides of piston B is opened when the spring R is fully wound and thereby stops piston B working more than is required to wind spring R. This valve is governed by the translational movement of a non-rotating nut running on the spring spindle.
