Title: Improved method of and apparatus for manufacturing concrete pipes
IPC: B28B21/12
Filed: 1933-06-20
Abstract: 421,583. Moulding pipes and tubes. BRADER, G. B., 61, Loxley Road, Wandsworth Common, London. June 20, 1933, No. 17556. [Class 87 (ii)] In the process of manufacturing pipes in non-centrifugal machines in which the mixture is delivered to and tamped in the annular space between a mould and a core extending the full length of the mould, both mould and core are rotated either in opposite directions or in the same direction at different speeds. In the illustrated construction a ring a<6>, shaped to form the lower end of the pipe, is mounted in a groove a<5> on the rotary table a, and a mould casing m, preferably in semi-cylindrical halves connected by bolts, is mounted on the ring. A conical-topped core c, rotated by bevel gear c<3>, is lowered into the mould to rest on the ring a<6> through the medium of a crosshead d raised and lowered by screw shafts s<2> operated by clutch-bevel-reversing-gear s<15> controlled by the hand-lever v<7>. A tamper t, Figs. 1 and 5, is raised and dropped periodically by mutilated friction wheels t<2>, t<3>. In operation the table a is rotated slowly while a comparatively dry concrete mix is fed in from the hopper r. The core is also rotated at the same time either in the same or opposite direction to the mould and at a greater or less speed. The tamper consolidates the material as it is gradually built up, and finally a spring-mounted strickle h shapes the upper end of the pipe and applies the final consolidating pressure. A trimming or fettling member k may finish the upper end. The hand-lever v<7> then is actuated to raise the core which also rotates during the process. When clear of the mould, a stop n<2> is operated automatically by the crosshead d to cut off the power. The mould and ring a<6> are then removed as a unit from the apparatus. The tamper is radially adjustable to operate on various sizes of moulds. In modified constructions the core is metal-cased so that the casing remains behind when the core proper is removed, or it is made of a split metal cylinder adapted to be expanded to the size required by an axially-sliding wedge. In the latter case, the upper end carries centring flanges for a disc on the end of the driving-shaft.

Filed: 1926-07-14
Abstract: 277,457. Major, P. F. E., and Coin Change Patents, Ltd. July 14, 1926. Change - giving apparatus; money boxes or receivers. - Relates to a change-giving mechanism for use with prepayment. gas meters and like apparatus, the coins used for operating s u c h apparatus being stored in a tube for delivery as change, alter the introduction of a coin of higher value. The apparatus is of the kind having a bent angle main frame, a toothed actuating wheel which is operated by a reciprocating pawl carried on the change removing slide and which is locked and unlocked by a bolt operated by the coin of higher value when this is moved by its receiving slide. According to the invention the receiving slide for the coin of higher value is carried by and slides in a channel guide screwed or secured to the back of the angle frame plate. The change coins stored in a tube 6, Fig. 3, are removed one at a time by reciprocating a slide 5 having a recess 47 to receive the lowermost coin and a pawl 28 which actuates a toothed wheel 3, turning this through one tooth at each reciprocation. Backward rotation of the wheel is prevented by a pawl 35 and it is normally locked by a bolt 20 until a coin of higher value, a shilling, is inserted. The wheel 3 has twenty-four teeth and two slots 26 for engagement by the bolt 20 after each half-revolution of the wheel. The end 30 of the pawl 28 is guided in a slot 31 in the main angle plate 1, the slot being inclined at one end so that the pawl 28 engages the wheel 3 during part only of the stroke of the slide 5. When there are no coins in the tube 6, the slide 5 is blocked by a lever 49, the inclined head 48 of which passes through a hole 52 in the slide into the recess 47. Coin action, mechanical-connect-ion.-The coin of higher value x, Fig. 1, is inserted through a shoot 13 to an open ended chamber 12 in a slide 10, which slides in a channel guide 11 screwed to the back of the frame 1 and is guided therein by a pin 18 passing through holes in the flanges of the guide. When the slide is pushed forward by a handle 14 until a stop 17 abuts against the pin 18, the coin moves a bell-crank lever 7 operating the bolt 20 and drops partly through a slot 19 in the lower flange of the guide 11. When the wheel 3 is moved, a bulge 27 thereon moves the bolt 20 and lever 7 further to allow the coin to drop to a money box. Fraud, preventing.-An incline 21 pressed out of the plate 1 below the slot 19 prevents a coin from being drawn back by means of a wire or silk thread.

Title: Improvements in logical switching devices
IPC: H03K19/16
Filed: 1959-05-26
Abstract: 881,378. Circuits employing bi-stable magnetic elements. INTERNATIONAL BUSINESS MACHINES CORPORATION. May 26, 1959 [Aug. 27, 1958], No. 17919/59. Class 40 (9). In a logical switching circuit using magnetic cores with appreciable remanence and low coercivity and comprising a biased input core C1, a storage core S and an output core C2 all initially in the " 0 " remanent state, an input signal " 1 " applied to core C1 reverses the remanent state of cores C1 and C2 to state " 1," while automatic restoration of core C1 to the " 0 " state by the bias, following termination of the input signal, causes core S to change to state " 1," the cores S and C2 being subsequently restored to state " 0 " by a read-out clock pulse IB. As shown, the core C1 is biased by a current Id.c. in a winding 38 and has an output winding 12 connected in a series loop A with a control winding 10 and input winding 14 on cores S and C2 respectively. When the core C1 is driven to state " 1 " by the input signal, a pulse is induced in the loop which reverses C2 but is without effect on core S since it acts in the existing " 0 " sense. A further pulse of opposite polarity appears in the loop when C1 is automatically restored to state " 0," this pulse reversing core S to state " 1 " but having no restoring effect on core C2 as the control winding 10 has a larger number of turns than the input winding 14. Due to the presence of a diode D in the circuit of output winding 24 of C2, an effective output pulse is obtained only when the cores S and C2 are restored to state " 0 " by a pulse IB in windings 40, 42. This output pulse is applied over a loop B to set cores C3, C4 and C5 to state " 1 " and these cores are subsequently restored to state " 0 " by a clock pulse IA. In a modification, Fig. 3 (not shown), an inhibiting winding is included on core C2. The core C1 may have any number of input windings such as 16, 18 and 20 as shown, and the bias may be adjusted so as to provide OR or AND operation. Alternatively two input windings wound in opposite senses may be used, this arrangement with a bias value such that a single input may reverse the core state providing the logical operation NOT IF THEN.

[Classes 39 (iii), 75 (i) and 126] In a cooker heated by gas, liquid fuel or electricity the heating unit is mounted on a folding or collapsable frame so that it can be raised above the level of the hot plate to act as a griller for food placed below it or lowered to heat utensils placed above it on the hot plate. Figs. 1 and 3 show a grill frame 3 fitted with a. removable frame 4 and supported on a base frame 1 by crossed links 7, 8 having pivot connections with the frames 1 and 3 at their left ends and pin-and-slot connections at their right ends so that by operating a lever 14 the grill-frame. can be raised to various heights above the hot plate 2. Springs 11 assist the upward movement of the grill frame. The burner 17 having a hinged supply.pipe 24 is supported by pins 18 on the links 7, 8 and guided by pins 19 on the frame 3. In the raised position the flames burn above and in the lower position below a flame deflector plate 5 supported by flanges 6 on the frame 3. A filler plate 20a mounted on the links 7, 8 closes the opening in the hot plate when the frame 3 is in the raised position. Fig. 4 shows a burner ring a formed with a gas passage 25 for heating a pan, kettle &c. placed in a frame 40 and a gas passage 26 for heating a grilling pan slidable in grooves 39 in side frames 38. The burner ring is fitted with a deflector plate 41 and is supported by adjustable cross links 27. The gas injector nozzle is mounted on a pipe 34 which is free to turn so that when the burner is in its boiling position the gas is delivered into the upper passage 25 and when the burner is in its grilling position the gas is delivered into the lower passage 26. The heating unit may alternatively be mounted on telescopic legs and be raised or lowered by a hydraulic device. When applied to an electric cooker the movement upwards of the griller may effect a switch-over of the electrical connection from the hot plate elements to the griller elements.
