Title: Improvements in filler charge shaping mechanism for cigar making machines
IPC: A24C1/08
Filed: 1930-12-30
Abstract: 370,410. Cigar-making machines. TRIGGS, W. W., 57, Lincoln's Inn Fields, London.-(International Cigar Machinery Co. ; 5520, 2nd Avenue, Brooklyn, New York, U.S.A.) Dec. 30, 1930, No. 39150. [Class 130.] Filler portions, particularly those for Toscani cigars, after being cut off are fully shaped before passing to the chianti belt for application of the binder. A tobacco web T is forwarded from a channel consisting of two horizontal and two vertical belts to the space beneath a slide 31, which as it descends causes the knife 36 to sever a length, and a projection 48 to open gates 47 beneath the slide allowing the severed portion to fall on a table 49. A slide 51 compresses the filler against a fixed abutment 65, the adjoining surfaces of these members being shaped so that the enclosed tobacco filler is tapered at each end. A vertical slide 68 is then depressed, and in conjunction with a recess in the two-part base member 78, 79 completes the shaping. As the slide 51 withdraws it opens the base parts 78, 79 ; the slide 68 continues its downward movement and ejects the filler into a cage 96. The underlying portion of the chianti belt 103 has meanwhile been lifted by the rod 104 into proximity with the cage 96 ; by a rod connection 97 with the slide 68 the cage 96 accompanies the belt in its fall, and ensures the correct positioning of the filler during the folding-over of the belt. Pins 119 enclosed in the slide 68 separate the filler from the mould ; as the slide falls a pin 124 depresses an arm 121 against a lateral projection from the pins causing the latter to protrude. A pin 117 also carried by the slide 68 presses on a sponge 118 supplied with liquid by way of a pipe 114 for moistening the charges. The various movements are effected by means of linkwork from cams carried by the main shaft of the machine.

Title: Treatment of timber
IPC: B27K3/02
Filed: 1971-08-23
Abstract: 1405754 Preserving wood PROTIM Ltd 23 Aug 1972 [23 Aug 1971] 39456/71 Heading D1P [Also in Division A5] Timber impregnation apparatus comprises a timber preservative storage vessel 2 and a transfer means to transfer preservative liquid to timber treatment vessel 1. Vessel 1 communicates with a first chamber 9 of relatively smaller cross section located above the vessel to receive liquid when timber vessel 1 is full. Vessel 1 also communicates with a second chamber 30 of relatively smaller cross section and located below the timber vessel 1 and storage vessel 2. The second chamber 30 has first and second level sensing means (for levels L2 and L5). The sensing means responds to the first level to control the liquid flow from the timber vessel 1 to the storage vessel 2, and responds to the second level to initiate a vacuum in vessel 1. The storage vessel 2 communicates at its upper end with a chimney of relatively smaller cross section having an initial liquid level sensing means L1 and a final liquid level sensing means L4. A means responsive to the initial level in the chimney is provided for drawing an initial vacuum in the timber vessel 1. In use:-Timber is loaded into vessel 1 and the storage vessel is filled to level L1 with preservative from bulk storage 3, and then a vacuum is created in the timber vessel 1 by pumps 12 and this vacuum is automatically maintained. Preservative is then pumped from vessel 2 into the timber vessel 1 by pump 23 and the preservative level rises from L2 to L3. The vacuum is then relieved in the timber vessel by opening valve 18 to the storage vessel 2 which is open to the atmosphere. The preservative is allowed to be absorbed into the timber for a predetermined time which is controlled manually or by a time delay relay. After absorption, the preservative is returned to storage vessel 2 and the level rises to L4. When the preservative in the timber vessel 1 falls to L5 the pump 23 is stopped and residual preservative draining from the timber causes the level to rise to L2. Pump 28 removes any further preservative draining from the timber. When the preservative reaches L2 again, vacuum is re-applied to the timber vessel and further preservative is drawn from the timber and pumped to storage vessel 2 until the amount of preservative in the timber (indicated by L1-L4) falls to a predetermined level. Then the pumps are stopped and the pressure in the timber vessel 1 is returned to atmospheric pressure. In a modified apparatus, the preservative may be forced into the timber under pressure generated by a pump. The preservative may be pentachlorophenol, tributyl tin oxide or gamma benzenehexachloride.

Abstract: 935,118. Resetting mechanism for slack adjusters. WESTINGHOUSE BRAKE & SIGNAL CO. Ltd. Nov. 15, 1961 [Nov.18, 1960], No. 39754/60. Class 103 (1). [Also in Group XXIV] A resetting mechanism for a slack adjuster designed to compensate automatically for wear of brake blocks or shoes and consisting of two interacting threaded members 7, 8 which are arranged to screw in and out of each other when the required stroke exceeds a predetermined amount comprises a non-rotatable housing 12 and means in the housing normally locking member 8 against rotation in at least one direction. The locking means has a portion engageable by a tool for rotation, an initial part of the rotation being effective to release the locking means and continued rotation being effective to cause rotation of the member 8. Attached to piston 1 which slides in a cylinder 2 provided with a trunk tube 3 sliding in a cylinder cover 4 is a slack adjuster mechanism 5. When the stroke of the piston 1 exceeds a predetermined amount a pawl engages a ratchet wheel 6 attached to the threaded member 7 on the return stroke of the piston so as to screw the member 7 out of the tube 8. At one end of tube 8 there is cut a spiral gear 11 which mates with a rotatable and slidable spiral gear 13. The outer end of the latter is provided with a square, slot, spline or other termination designed to engage with a resetting tool. A peg 16 engages with a slot 17 cut in the same sense as the teeth on the gear 13. On initial rotation of the gear 13 it moves to the left of Fig. 2, due to the angular relation between the peg 16 and the slot 17. Further rotation causes it to abut against a face 18 in which position the peg is out of engagement with the slot 17 so that the gear 13 can turn the tube 8. A spring 15 ensures that the gear 13 is normally held against cover 14 sufficiently to prevent movement due to vibration.

Abstract: 1280498 Coin handling N MEIER and C ALBRECHT [trading as MEIER & ALBRECHT] 15 Aug 1969 [3 Dec 1968] 40839/69 Headings G4V and G4X A coin-handling machine comprises a plurality of gravity shoots 26 (Fig. 2), each divided into three or more successive sections 27, 29, 31, an intermediate section 29 being movable transversely to the axis of the shoot for diverting a coin to a coin return tray 40, a coin retainer 42, or a lower section 31 of the shoot that stores coins for transfer to the coin return tray 40 by one or more apertured slides 45. With the intermediate section 29 in the position shown in Fig. 2, a coin 25 comes to rest on the bore surround 36; movement of section 29 to the right (Fig. 4, not reproduced) forces the coin 25 down a sloping face 38 and a slide 43 into the coin return tray 40. Movement of section 29 to the left (Fig. 3, not reproduced) drops the coin through the bore 30 into the lower section 31 unless filled with coins or covered by a cap, when further movement of section 29 to the right pushes the coin down a slide 44 to the coin retainer 42. The lower section 31 may be closed at its upper end by a cap, and filled with currency replenishable through a top or side slit (not shown). Coins stored in the lower section 31 are transferred to the coin return tray 40 by a spring- urged, apertured slide 45 actuated by an electromagnet 53. Several slides 45 may be superimposed to slide independently or together. Coin insertion.-A coin 13 (Fig. 1) inserted in a coin slot 11 displaces a pivoted shutter 21 that breaks a contact 23 to prevent operation of the intermediate section 29 (Fig. 2) and apertured slide 45 while the coin is in motion down an inclined shoot 22 and the upper section 27 of the shoot (not further disclosed). Shutter 21 (Fig. 1) prevents fraudulent machine operation when a wire or rod is inserted in coin slot 11. A cross-member 14 projecting across slot 11 is slotted at 15 to normally allow coin insertion, but is rotatable under the action of arm 16, spring 18, arm 19 and electromagnet 17 to limit coin diameter. Coin testing is carried out at 24 (Fig. 2) to reject incorrect coins (not further disclosed). A separate coin slot 11 and gravity shoot 26 are provided for each coin denomination. The upper and/or lower sections 26, 31, or the intermediate sections 29 may be integrally formed of metal. The coin handling machine can vend articles, issue change, return coins, or exchange a sum of coins for an equivalent sum in the same or foreign currency. Coin slots are blocked after a maximum number of coins has been inserted (not further disclosed). Petrol pump.-The coin-handling machine may be used in conjunction with a self-service petrol pump (60) (see Fig. 5, not reproduced) having measuring equipment (62), a fuel pump (63), a valve (64) providing two delivery speeds, a cash unit (65) including the coin-handling machine, and electronic control equipment.

In the process for producing sulphur by the Claus process, H 2 S is reacted with a deficiency of O 2 ; the resultant gases after separation of sulphur, consisting of H 2 S and a little SO 2 , are cooled and passed with O 2  through active carbon to form and deposit sulphur; the charged carbon is desorbed with a hot inert gas or steam; and the desorbed gases are recycled to the initial H#2S/O 2  reaction. The H 2 S and O 2  may be passed to a combustion vessel where S is deposited and SO 2  also formed, and the gases passed to a first catalytic reactor where H 2 S and SO 2  react to give further S, then through first and second heat exchangers to condense out S. The gases return through the first exchanger and are passed to a second catalytic reactor, then cooled in a third heat exchanger to separate further S, mixed with O 2  or air and passed through the carbon. Desorption may be effected with inert gas at above 220‹ C. or steam at 300-400‹ C.; with steam, the gases contain some H 2 S and SO 2  in addition to S. The desorbed gases may be recycled to the combustion reactor or to the first or third heat exchanger.
