Title: Improvements in or relating to recording scales
Inventor: DRILLICK JOHN H
IPC: G01G23/18
Filed: 1957-01-25
Abstract: 842,643. Recording scales. KIMBALL CO., A. Jan. 25, 1957, No. 2830/57. Class 143 A recording scale comprises a movable weighing platform, an indicator member movable with the platform and having code perforations therein, a number of independently movable sensing pins for sensing individual perforations, one or two pawls and a permutation disc connected with each sensing pin, and means controlled by the relative positions of the permutation discs for setting a number of printing wheels in accordance with the weight on the platform. As shown, indicator discs 4, 5 (Figs. 1, 5) fixed to shaft 1 and having thereon code perforations 16 relative to price and weight respectively are rotated by vertical movement of the weighing platform 15. On pressing an operating button, a solenoid-controlled latch engages teeth 17 (Fig. 5) to lock the discs (enabling the load to be changed during the subsequent printing cycle) and starts motor 30 (Fig. 1) which rotates the main control shaft 33. A cam 34 (Fig. 4) on shaft 33 rocks shafts 42, 43 (Figs. 4, 7) to move rods 55, 56 away from pawls 44, 45 allowing those pawls whose corresponding sensing pins 19 (Fig. 8) are opposite perforations in discs 4, 5 to move under the influence of springs 52, 52a, into engagement with permutation discs 46, 47. A rod 94 is then rocked about shaft 70 (through linkage from a cam 85 on shaft 33) allowing sectors 69 to rotate bails 61 (one to each group of permutation discs, see Fig. 7) until a pawl 63 on each bail engages aligned code slots 83 on the discs, each of which has rotated under the influence of a spring 81 until stopped by the end 57 of a pawl 44 or by a stop 78. Sectors 73, rigidly attached to sectors 69, set printing wheels 21, to record the price of the article on the scale. Similarly wheels 22 (Fig. 7) are set to record the weight. Wheels 23 record the price per pound and are moved as described below, only when the price of goods weighed is changed. A platen 140 (Fig. 10) pivoted at 132 and carrying a paper strip S and inking ribbon R, is stamped on to the printing wheels by links controlled by cams on shaft 33. Changing price disc. Disc 4 carries perforations for one price only. To change the disc, arm 107 (Fig. 5) is moved downwards, this causing a frame 114 pivoted on shaft 77 to move downwards into the position shown in Fig. 10, where three wheels 116 mounted on concentric shafts are in position to engage segements 73. Wheels 115 on the shafts of wheels 116 engage wheels 118 fixed to printing wheels 23 (Fig. 7). On the downward motion of frame 114, wheels 23 are zeroed by springs 1151 and during the next printing cycle, with no weight on the scale pan, the wheels are set by code perforations on the new disc 4, after which an arm 123 of the paper feed mechanism strikes a pin 129 and allows frame 114 to move upwards under the influence of a spring 122 until gears 115 engage a latch 119, thus locking wheels 23 in their new position.

Title: Improvements in or relating to single-track working systems for railways
IPC: B61L23/22
Filed: 1951-02-09
Abstract: 723,966. Control of points at railway passing sidings. SOC. TECHNIQUE POUR L'INDUSTRIE NOUVELLE SOC. ANON., STIN. Feb. 9, 1951 [Feb. 10, 1950], No. 3265/51. Classes 104 (1) and 105. For traffic between two stations A, B on a single track line with an intermediate unattended passing-siding section 3, normally the trains travel over the main track at the intermediate passing-siding section 3 but if an East-bound train is already in the single track section 1 at one side of the section 3 and a West-bound train enters the single track section 2 at the other side of the section 3 then the points are set to the siding for the East-bound train. The wayside signal for the East-bound train at the entry to the intermediate section 3 then displays the take-siding signal S3<SP>1</SP> instead of the main track signal S3 while for the Westbound train the signal S4 for entry to the intermediate section 3 is at stop until the East-bound train is completely within an insulated length on the passing siding and so has allowed the points to be restored to the main track setting. If the East-bound train had already reached the intermediate section 3 the signal S2 at station B for admission of the West-bound train to the single track line would have been held at stop. The signals for entry to the intermediate section 3 are situated to provide sufficient overlap before the points of the passing siding. The control may be by track occupancy or by the clearing of the signals S1, S2 (for entry into the single track and passing siding stretch) at the stations A, B at the opposite ends of the stretch.

Title: Process and means for separating dissolved metal compounds from mineral acids
IPC: C01G49/14
Filed: 1966-01-25
Abstract: <PICT:1112703/C1/1> Metal salts and/or oxides are obtained from acid solutions, e.g. pickling solutions, by spraying the solution (through nozzle 6) into a highly turbulent gas stream consisting of a mixture of hot gas and return gas (supplied through lines 3 and 5) and withdrawing a suspension of the solid product in gas and acid vapours (through conduit 8).  As shown in the Figure, to which the above numerals relate, baffles 2 cause turbulence of the upflowing gas and sprayed droplets.  In the case of a solution of iron sulphate, iron chlorides, sulphuric acid, hydrochloric acid and water, hot gas at a temperature of 1200 DEG  C. is introduced through nozzle 4, gas at 380 DEG  C. is returned through pipe 5, and the gas mixture has a temperature of 420 DEG  C., whereby only the iron chlorides are decomposed.  The suspension of solid particles in conduit 7 enters cyclone 9, and the major part of the particles is separated.  The gases pass on to tower 10 where the acid vapours are absorbed in water.  Before the absorption of the acid vapours, the gases may be used for preheating and preconcentrating the acid solution to be treated.

Patent GB-1489657-A (GB)
Title: Vending and like machines
IPC: G07F5/22
Filed: 1975-01-27
Abstract: 1489657 Control circuit for vending machine HR ELECTRONICS CO 27 Jan 1975 [25 April 1974] 3408/75 Heading G4V [Also in Division G3] The invention concerns the control circuitry of a coin operated vending machine. An adder circuit (Fig. 2) is employed which receives at B inputs logic signals representing which of a number of articles have been selected to be purchased and delivers at its output a logic signal which causes a selected article to be delivered and change to be given. The output of the added is returned to its input and it is stated that the adder performs a sequence of adding operations in response to the input which eventually results in only one of outputs S 2 -S 4  being set so that only one article is delivered despite more than one of the article selecting switches 144-147 being operated. In Fig. 1 an accumulator 30 adds the total value of coins inerted as detected by switches 24-28. A matrix 54 delivers the price of a selected article. The total credit is compared at 36 with the price and if adequate enables the control circuit 72 (Fig. 2) by input terminal R B . Depending on the amount of excess credit various outputs 60, 62 of the comparator circuit are also enabled to set up the change paying apparatus. Control circuit 72 is enabled and adder 150 adds the selection input to a fixed input at A 1 -A 5 ; after the first addition a carry-out terminal 124 goes to logic 1 and inhibits the selection input so the adder then responds only to its own output. An output on one of the lines S 2 -S 6  energizes through a relay 116-122 a corresponding delivery motor 130-1350 which delivers the selected article. When delivery is detected by interface 134 the control circuit 72 enables an output S 1  to pay out the change selected by comparator 36. The selection interface 74 employs opto-electronic couplers to isolate the control circuitry from the motor supplies (Fig. 17, not shown).

Title: Typewriting machines
IPC: B41J23/06
Filed: 1944-02-28
Abstract: 571,740. Typewriters. CARPMAEL, A. (Royal Typewriter Co., Inc.). Feb. 28, 1944, No. 3695. [Class 100 (iv)] In a power-driven typewriter in which a power-lever 35 operates a part of the machine, e.g. type action, ink-ribbon vibrator mechanism or the carriage escapement mechanism and has mounted thereon a rotatable star-wheel 49, the fingers 50 of which engage projections 27 on a rotatable power-driven element 26 to operate the part of the machine when the axes of the two members 26, 49 are moved towards one another, means being provided, mounted independently of the power lever, to prevent overthrow of the star-wheel 49, these means comprise a stop-bar 54 carried by arms 53 and normally held in the path of the fingers 50 to prevent overthrow movement thereof, but is forced backwardly by one of the fingers when the succeeding finger is in driving relationship with one of the projections of the member 26. The connection between each power-lever 35 and the corresponding type-lever 19 includes a spring cushioning-element which serves to impart additional acceleration to the lever 19 after the latter is well under way. Links 37, 42 connect the levers 35, 19 respectively to a lever 38 pivoted to a lever 40, itself pivoted to a part 24 of the machine frame. A spring 45 normally holds the arm 44. of the lever 40 in engagement with the frame part 24, all the springs 45 being attached to a universal bar 46 mounted by a screw-and-slot connection 47 on the part for adjustment of the tension of the springs. During initial movement of the lever 35, the spring 45 corresponding thereto is distended to cushion the force exerted on the type-lever. 19 and subsequently contracts to accelerate the movement of the type lever. A pivoted member 80 connected by a spring 82 to the lever 35 has a stop face 86 normally engaged by a projection 85 on the lever 35 to prevent the latter moving and causing driving engagement between the members 26, 49. Operation of a key E tilts the member 80 so as to allow the projection 85 to slide past the face 86 and thus the star-wheel 49 moves downwardly so as to be engaged by the driving member 26 so as to move the lever 35 in an anti-clockwise direction and thus operate the type lever 19. A second impression is prevented, if the key E remains depressed, by a spring-controlled arm 87 pivoted on the stopmember 80. During the first movement of the power-lever 35, the projection 85 enters between the face 86 on the member 80 and a face 90 on the arm 87. If, however, after the projection 85 has been withdrawn during the actuation of the type-bar 19, it again attempts to rise, it engages a second face 91 on the arm 87 which prevents a further impression operation. When a type-lever 19 moves to printing position, it actuates a universal bar 58 connected by linkages 59 ... 68 to a trip frame 14. A stop 13 on the frame 14 engages a roller 12 on an arm 10 to operate the escapement mechanism D for letter-spacing the carriage B, and a. pin 22 thereon actuates a device 21 connected to the ribbon vibrator mechanism.
