Title: Improvements in the processing of brewers' wort
Inventor: SHORE DAVID TEIGNMOUTH
IPC: C12C7/20
Filed: 1959-11-20
Abstract: <PICT:0947515/C3/1> In filtering and hopping brewers' wort, the wort is passed through a first quiescent bed of hops which has previously had wort passed through it, and is then passed through a second quiescent bed of fresh hops.  Preferably, after the bed of fresh hops has become vitiated, the wort flow is switched to flow first through this vitiated bed and then through a third quiescent bed of fresh hops. Fig. 2 shows an arrangement in which three hop extraction vessels 12, 13 and 14, are used with control valves enabling any one of the vessels to be used as the primary hop extraction vessel and the others to be used, after being employed for the primary hop extraction, respectively for filtering and re-charging with fresh hops.

Title: Automatic vending machine
IPC: G07F11/50
Filed: 1962-10-22
Abstract: 981,465. Coin freed vending apparatus. H. THRONER, and W. SCHNEIDEREIT. Oct. 22, 1962 [Oct. 27, 1961; March 17, 1962], No. 39821/62. Heading G4V. In a vending machine having a multi-storey stack of radially disposed goods compartments 3, Fig. 1, the stack is rotatable about a vertical axis to view the goods through a window 11 as they are transported towards access hatches 7, such rotation being effected by a purchaser after insertion of coinage in a slot 8 and by pressing a pushbutton 9, the access hatches 7 being locked while the stack rotates. As shown in Fig. 5 the access hatches 7 pivot about their bottom edges and each have a notched side plate 24, pins 23 on a locking bar 25 engaging the notches. Vertical movement of the locking bar 25 is prevented by a solenoid operated detent for as long as the motor rotating the compartment stack is energized. Opening of a hatch 7 is further prevented until a compartment is in line with the hatch when a lever 27 connected to the top of locking bar 25 enters a notch on the top edge of the stack. The position of the stack with a column of compartments in line with the hatches 7 is also defined by a solenoid actuated locking member which engages one or other of a ring of projections from the base of the stack, Figs. 7 and 8, not shown. The stack rotates on a large diameter ball race and is driven by a geared motor and a chain drive, Figs. 3 and 4, not shown. In place of a chain drive the bottom of the compartment stack may be encircled by and be fast with a roller chain driven by a sprocket wheel on the motor shaft, Figs. 10, 11, 12, not shown. Control circuit Fig. 9. Passage of a coin through a testing device results in actuation of contacts 33 and the operation and locking up of relay 34. A pilot light 35 shows the apparatus is now ready for use and the user presses button 9. Solenoids 37 and 21 energize to lock the locking bar 25 by means of detent 39 and to release the stack 2 for rotation by withdrawal of detent 38. With solenoid 21 operated contacts 22 operate relay 36 and connect drive to motor 12. The stack rotates with a cam roller 41 breaking contacts 13 in parallel with the button 9 each time the compartments are in line with the hatches 7. When the desired goods move behind a hatch 7 the button 9 is released and contact 13 maintains drive until the cam roller 41 indicates that the compartment is in line with the hatch. Solenoids 21, 37 and relay 36 restore, with the stack locked by detent 38 and the locking bar 25 released by detent 39. A hatch may now be opened and, as the locking bar 25 rises, contacts 28 operate to release relay 34. Once a hatch 7 is opened the deposited coin is encashed. Should no goods of the kind sought be available in the machine, the deposited coin can be regained by a coin-return button 10 actuation of which breaks contacts 43 to release relay 34. To rotate the stack when loading the machine with goods a switch 44 is provided within the casing.

Abstract: 1,099,897. Escapements. UNITED STATES TIME CORPORATION. Sept. 7, 1966 [Sept. 29, 1965], No.40058/66. Heading G3T. An escapement mechanism for a watch comprises an index wheel 60 and a helical gear 26 mounted on a staff 32, means being provided to axially move the helical gear once every second from an initial setting position to a rapid indexing motion. A seconds hand 22 and a seconds wheel 14 are mounted on a shaft 20 pivoted between bridges 16, 18. A curved arm 80 attached to a frame plate 10 is biased into engagement with one of four spokes 78 which define slots 84 in the index wheel 60. The index wheel is rotated through one revolution in four seconds by a lever 48 which is oscillated by a pin 68 attached to a roller 66 fixed on a balance staff 70. Rotation of the index wheel 60 causes the arm 80 to enter one of the slots 84 so that a spring 42 cams the staff 32 and the helical gear 26 upwards. The teeth 28 of the helical gear thus cause a sudden intermittent rotation of the seconds wheel 14 and the arm 80 engages the edge 87 of the following spoke 78 so that further rotation of the index wheel cams the gear 26 back to its initial position.

Abstract: 935,880. Toys. DAISY MANUFACTURING CO. Nov. 10, 1961 [March 10, 1961], No. 40387/61. Class 132 (3). A toy pistol comprises in combination a housing 22, a chamber housing 66 within the housing 22, a spring 86 pivotally mounted on the housing, a portion of the spring extending into the chamber housing for propelling pellets 134 disposed within the chamber housing, a hammer 38 pivotally supported on the housing operatively connected to the spring for moving the spring with respect to the chamber housing into a cocked position, a trigger 30 pivotally supported on the housing releasably engaging the hammer for locking the hammer against pivotal movement in one direction, latch means, a sear 96 restraining the spring in the cocked position when the hammer is in a predetermined position, and means including the trigger, the hammer and the sear for releasing the spring from the cocked position. To load the pistol with pellets, a flexible shot follower 48 in a subbarrel 42 and extending into a feed tube 60 is moved by a tab 52 against the action of a spring 46 to free an aperture 44 through which pellets are fed. The pellets are moved upwardly into the tube by the shot follower when it is released. A button 76 in the chamber 66 is urged by a spring 74 to close the entry of the tube to a bore 80 communicating with a firing barrel 64. To load a pellet into the bore, the hammer is pivoted to its extreme position, a draw link 98 on the hammer pivots the spring 86 so that it displaces the button 76 to allow a pellet to enter the bore 80, where it is retained by a projecting stop spring 78. The hammer is released to its cocked position where a portion on the trigger engages a shoulder on the hammer. and tensions spring 126. The spring is held by a projecting end of the sear so that the force acting on the hammer is reduced and lessens the pressure necessary on the trigger to fire the pistol. Pulling the trigger frees the hammer which rotates under the action of the spring 126, and a cam projector on the hammer strikes a groove on one end of the sear which pivots and releases the spring 86 which rotates and propels a pellet along the barrel 64.
