Title: Improvements in mechanism for automatically reversing the direction of rotation of amachine or a rotating part thereof
IPC: D06F13/02
Filed: 1944-02-03
Abstract: 574,497. Reverse gearing; machinery guards. BRAITHWAITE & SON ENGINEERS, Ltd., I., and BANKS, W. Feb. 3, 1944, No. 1982. [Classes 80 (ii) and 80 (iv)] An automatic periodic' reversing gear for a machine, such as a rotary washing or drying machine, comprises a driving shaft B, Fig. 4, which drives through a clutch D a shaft C, which in turn drives a compound gear H<1>, H<2> on a counter-shaft J through sliding pinions G<1>, G<2>, either direct or through a reverse idler (not shown). Gear H<2> drives through a train H3, H<4>, H<5>, Fig. 2, the cylinder H<6> of, for example, a washing machine. The clutch D, a brake E acting on the shaft C, and the sliding pinions G<1>, G<2> are operated automatically and in sequence to reverse the direction of rotation of the cylinder after a given time by cams M and Q, Figs. 4 and 7 respectively, on a cain-shaft L<1> driven from shaft B at a reduced speed. A common sliding member P for the clutch and brake is actuated by a bell-crank lever N<2>, Fig. 4, engaging cam M by a roller N<1> under tension of springs N<4>, N<5>, whilst cam Q, Fig. 7, actuates the sliding pinions G<1>, G<2> through follower levers R<1>, R<2>, spring link T and a forked lever T<1>, A single control lever U<1> has three positions, one in which the periodic reversal continues auto-. matically, another in which a cam N<6> on shaft N<3> releases the pivot S<1> of follower lever R<2> so that one direction of rotation only is selected and maintained by follower R<1> riding on the top of cam Q, and a third in which the clutch is disengaged and the brake applied to stop the cylinder by dogs on the cam N<0> engaging dogs on the bell-crank lever N<2>. A certain amount of lost motion between these dogs allows of " inching " between the second and third positions 'of lever U<1> and an indicating disc Y<1> geared to the cylinder is provided to assist the operator to position the cylinder for opening. In its third position, the lever U<1> moves its shaft V<5> axially to raise a locking lever W<1> clear of the end of a flange X<1> on the sliding door X<2> of a cover for the cylinder, to allow it to be opened. The lever U<1> cannot be moved for starting, by reason of lever W<1> engaging the top of flange X<1>, until the door X<2> is closed.

Title: Improvements in or relating to garbage disposal apparatus
IPC: E03C1/266
Filed: 1954-01-26
Abstract: 745,978. Garbage disposal apparatus. HAMMES, F., [Representative of HAMMES, J. W.]. Feb. 24, 1954 [Jan. 26, 1954], No. 2253/54. Class 59. [Also in Group XXXVII] In a garbage disposal apparatus associated with a kitchen sink and having a garbage and water receiving chamber 10, 11 with a motor-driven comminut- or 21 therein, the motor 19, which is reversible, is included in an electric circuit having a reversing switch 34 adapted to cause the motor to run in opposite directions during successive periods of operation and switching means 27 responsive to adequate flow conditions within the chamber to close the electric circuit. The reversing switch includes pairs of fixed contact arms 35, 36 with co-operative movable contact arms 37, 38 operating between the respective pairs of contact arms and successively moved in reverse directions by means of an oscillatable actuator 47 which is successively rocked in reverse directions upon energisation and de-energisation of a solenoid 42 controlled by the switching means 27, The switching means 27 comprises a flap valve 22 mounted fast on a shaft 23 journalled through the upper wall of a drain extension 13, the shaft 23 having fast thereon a knurled operating knob 24 having an integral sleeve 24<SP>1</SP> which functions as a cam and has a flattened surface 25 thereon. Riding on the cam sleeve 24<SP>1</SP> is the free end portion of a yieldable switch contact arm 26 anchored to the bottom of a switch box 27. When the apparatus is inoperative, or when there is an insufficient head of water reacting against the valve 22, the valve is in the position shown in Fig. 1 preventing material passage through the drain 13, 14, and the switch arm 26 is separated from a contact element 28 depending from the switch box 27. When there is a sufficient head of fluid reacting against the valve 22, the pressure causes the valve to swing towards its open position, Fig. 3, This swinging movement turns the shaft 23 and cam sleeve 24<SP>1</SP> to cause a raised portion of the cam sleeve to move the contact arm 26 into engagement with the contact element 28 and close the circuit through the switch mechanism 27. The switch box 27 can be moved pivotally, by means of a laterally projecting rod 54, into the dotted line position, Fig. 3, to dissociate it from the valve 22 so as to permit flow of fluid without operation of the comminutor 21. The switch box may also be moved to the dotted line position when refuse is jammed against the valve plate 22, the switch box being turned down manually to its operative position or manipulated to close the contact arm 26 to cause operation of the motor 19 so as to clear the jammed refuse. U.S.A. Specification 2,225,171 is referred to.

Title: Method and apparatus for the removal or recovery of vapours from air or other gases
IPC: B01D53/02
Filed: 1958-01-27
Abstract: <PICT:0836282/III/1> In a process for separating gases and vapours, and especially removing solvent vapours from air, an activated absorbent in finely divided form, is dispersed in the air stream and then conducted through a filter surface, where they form a permeable layer further purifying the air.  Preferably an excess of active charcoal, alumina or silica gel of particle size minus 200 to plus 35 (Tylor) is used.  Vapours removed include solvent vapours, volatile organo-metallic compounds, halogenated hydrocarbons, or acidic gases such as H2S, So2 or phosphine.  In a suitable appratus, a stream of air flowing through a passage 14 draws in a regulated amount of a finely-powdered absorbent 11, and the resulting turbulent flow disperses the absorbent in the gas; additional means to cause turbulence may be mounted in the passage 14.  The dispersion passes to a plenum chamber 22 on which is mounted a series of filter tubes 18 containing filter bags made of cotton, or a synthetic fibre.  The filtered air escapes around the filters.  When a drop in pressure indicates an excessive deposit of absorbent, the filters may be agitated by a handle 20, when the absorbent falls into a sump 28, and may be regenerated, e.g. by steam.  Alternatively the absorbent may be removed from the filters by reversing the air stream.  U.S.A. Specifications 2,137,254 and 2,143,664 are referred to.

Abstract: 165,490. Rudge-Whitworth, Ltd., and Pugh, J. V. Jan. 29, 1020. Detaching from, and attaching to, permanent hubs.-In means for securing and centring an outer hub on an inner hub, the members are each provided with two axially-separated zones of engaging-means having non-radial faces so inclined that axial pressure of one part on the other rigidly centres them and, by causing the engaging-means to bind on opposite faces, induces a torsion which eliminates rotational slackness. The outer hub-part b is forced on to the axle a by a nut &c. screwing on the end e thereof, Figs. 1 and 2, and engages the axle by inner and outer zones of corrugations c, d of taper form, respectively converging on apices c<1>, d'. The recesses c<2>, d<2> of the part b lie in the same radial planes, but the crests c<3>, d<3> of the part a have a small relative angular displacement, so that contact takes place under the axial force of the nut &c. on opposite flangs c<4>, d<4> of the two sets. In a modification, the set d is replaced by small parallel serrations, when correct angular displacement of the set c mav be ensured by a "pilot" key on the parallel portion of either member loosely engaging a groove just prior to contact of the main engaging-faces. In a further modification, the corrugations c are also replaced by a short set of serrations formed on a larger diameter than the outer set, and taking a somewhat helical direction, the angle of the helix preferably exceeding the friction angle. In this case, both sets may be helical, provided that the inclinations are of different degree or opposite sense. In another form, the parts a, b engage by two zones of polygonal cross-section, one or both being tapered, and the inner zone being of larger diameter than the outer. The sets of poly. gonal faces on either part may be angularly displaced, or opposite ends of the faces on either part may be relieved as at k<1>, l<1>, Fig. 9.
