Title: Apparatus for heating and dispensing heat-storage elements
IPC: A47J39/02
Filed: 1961-10-10
Abstract: 951,702. Shoots &c. B. S. RICHNER. Oct. 10, 1961 [Oct. 28, 1960; June 19, 1961] No. 36346/61. Heading B8S. A plate warming magazine 1 has means for releasing a single plate 10 (Fig. 1) at a time. The plates are for keeping dishes warm, and a heater 2 surrounds the magazine for this purpose. The stack of plates 10 rests on stops 30 until they are deflected by the action of an empty plate holder 7 inserted laterally into position beneath the magazine 1. The holder 7 engages a stop 20 which is connected to linkage 16, 18, so as to deflect the stops 30. This permits the bottom plate 10 to fall into the holder 7, but the remaining plates 10 are held by stops 31 which move inwards as the stops 30 move outwards. In a modified construction (Fig. 6), the stack is supported on a plate 45 which is adapted to be deflected laterally from its position beneath the stack by the insertion of a plate holder 48. Rails 50, 50, on the surface of the plate 45 engage followers 57, and due to the inwards kink of each rail, cause members 53 (rigid with the followers 59) to be projected inwardly to support the stack above the lowest plate 10. On withdrawal of the holder 48 with the lowest plate 10 thereon, the plate 45 returns under the action of springs 51, and members 53 are retracted so as to deposit the stack on the plate 45.

Title: Improvements in knitting machines
IPC: D04B11/22
Filed: 1932-12-23
Abstract: 396,280. Straight-bar knitting- machines. WILDMAN MFG. CO., Norristown, Pennsylvania, U.S.A.-(Assignees of Howie, K. ; Norristown, Pennsylvania, U.S.A.) Dec. 23,.1932, No. 36518. Convention date, March 3. [Class 74 (ii).] A full-fashioned knitting-machine is provided with a picot bar 1 movable either to idle position away from the needles or into working position. The bar is operable longitudinally by one of the narrowing point carriers. While narrowing is performed the picot bar is in its upper position. The movement of the narrowing point carrier is recuced when the picot bar is in operation. The adjusting means for yarn carrier stops is thrown out of operation while picot is being formed. The picot bar 1 is adjusted to operative position by swinging it down from an elevated position by hand so that its transfer points 1a stand over and in line with alternate needles. The rock shaft 2 carrying the bar 1 is journalled in bearings 4 in the vertically swinging fashioning frame 47. The bar 1 is held down in working position by engagement of a clutch collar on the end of shaft 2 with a clutch on the bearing 4. The clutch has teeth of such length that the shaft 2 and bar 1 have sufficient limited length-wise movement, without disengagement, to transfer the picot loops. This transference is effected in the same general way as in narrowing by pawl and ratchet mechanism 45, 46. To hold the pawl 46 out of the path of ratchet 45 a cam 24a on the yarn change shaft b acts on a spring pin 32 carried on a link 33 connected to the pawl 46. When the ratchet descends the pawl 46 is freed and is caused by the pin 32 &c. to stand away from the ratchet in its upward movement. A second cam surface 24b keeps pawl 43k from turning shaft 43 which controls the yarn carrier stop mechanism at this time. The screw shait 18 is operated by hand to set the narrowing points to idle position out beyond the ends of the bar 1 and is automatically reciprocated for picot work sufficient to displace the narrowing point carrier and bar 1 one needle space. After formation of the picot the narrowing points are moved inwardly from their outward positions beyond the ends of the picot bar, into position for narrowing.

Title: Method and means for guiding metal strips of a considerable length in a rolling mill
IPC: B21B37/64
Filed: 1959-11-02
Abstract: 930,907. Rolling. INSTITUT DE RECHERCHES DE LA SIDERURGIE. Nov. 2, 1959 [Jan. 3, 1959 ; Jan. 23, 1959], No. 37078/59. Class 83 (4). In guiding strips of a considerable length in rolling mills the adjustments on either side of the mill are corrected simultaneously and automatically by an amount larger than that necessary to precisely overcome the mill spring. Over-compensation is provided by reducing the stiffness of a spring 13, Fig. 4, included in an adjustment system similar to that disclosed in Specification 930,906. It is stated that synchronous automatic adjustment of the screws 15 cancels the excess compensation so that the strip remains centrally located and is also maintained at constant thickness. Instead of automatically adjusting the screws 15, the over-compensation may be cancelled by modifying the position of the switch constant piece 3 using plungers 16 working in opposition to springs 17, Fig. 5, or directly attached to and in opposition with the plungers 14, Figs. 7 and 8, and subjected to the means of the pressures in the jacks on either side of the mill or merely to the value of the pressure in the jack on the other side of the mill respectively. In the case of the arrangement of Figs. 7, 8, the value α-# may assume a predetermined value corresponding to a precise compensation of mill spring, while the value of α+# is such as to ensure stability of strip positioning, a and # denoting the cross-sectional areas of the plungers, e.g. 14 and 16 respectively.

Title: Thermal relay for polyphase currents
IPC: H01H83/22
Filed: 1961-10-17
Abstract: 994,436. Electrically-released switches. NORMACEM. Oct. 17, 1961 [Nov. 9, 1960], No. 37189/61. Heading H2B. A polyphase thermal protective device has a plurality of bi-metallic strips 1a, 1b, 1c arranged in parallel planes and having free ends engaging in a pair of slidable bars 3, 4, and a contactcarrying member 6 latched to the bar 3. The strips 1a . . . 1c are heated by the phase currents and under balanced overload conditions move both bars 3, 4 to the right until the bar 3 abuts a member 2. The movement of the bar 3 ceases and the continuing movement of the bar 4 moves the member 6 relative to the bar 3 so that the member 6 is released from a tongue 3e of the bar 3. The member 6 then moves upwardly under the bias of spring 8 to open contacts 9, 10 and close contacts 9, 11. In the event of unbalance between the phase currents, the resulting relative movement between the bars 3, 4 causes the release of the member 6 from the tongue 3e, irrespectively of the setting of the member 2. The setting of the member 2 determines only the magnitude of balanced overload currents to cause tripping, and the member 2 may be bi-metallic strip for ambient temperature compensating purposes. Resetting of the device is effected when the strips have cooled by depressing the member 6. The initial position of the strips may be adjusted by eccentric screws 13.

Abstract: 1,116,999. Jet propulsion plant. GENERAL ELECTRIC CO. Aug. 19, 1966 [Dec. 30, 1965], No. 37278/66. Heading F1J. A variable area nozzle for a gas turbine jet propulsion engine includes inner and outer pivoted flaps 28, 32 movable between a convergentdivergent supersonic configuration, Fig. 2, and a subsonic configuration, Fig. 3, by means of the differential fluid-pressure acting across the flaps. In order to reduce the air pressure in cavity 50 bounded by the flaps 28, 32, convergent flaps 20 and a baffle 70 across a by-pass passage 11, air is bled from the engine compressor through a pipe 58 to an ejector pump 52 formed by a nozzle 56 on pipe 58 and a surrounding aspirating tube 54. Such pressure reduction enables the flaps 28, 32 to remain in their subsonic configuration until internal pressure increases to the extent that the flaps move towards their supersonic configuration. A solenoid operated valve 62 controls operation of the pump 52. The secondary air from by-pass passage 11, which may or may not contain a ducted fan, passes as cooling air through passages 20a in flaps 20 to enter the nozzle interior. The adjacent ends of flaps 20, 28, 32 are connected by linkage 42. A spring system may be provided to overcome friction at the flap seals.

Abstract: 1471348 Automatic control systems OKUMA MACHINERY WORKS Ltd 28 Aug 1974 [30 Aug 1973] 37626/74 Heading G3N A high accuracy feedrate control for a numerically controlled machine tool, e.g. a lathe, has a desired feedrate #F and an actual tool movement #S calculated from the components of the tool movement as measured along the x and z axes, i.e. #x and #z respectively. Using pulses from a tool spindle driven pulse generator PG, the cumulative total #F and the ratio M = ##F/#S are calculated. From these values subtractor SUB and multipliers MUL 1 , MUL 2  and MUL 3  respectively calculate E = ##F-M#S, M.#S, M.#z and M.#x. The tool feed rate control in the x and z directions is then made by the cumulative totals of #M.#x and #M.#z respectively provided E is greater than, or equal, to zero. If #F is less than #S, M is given the value of unity, otherwise M is the integral portion of the ratio ##F/#S. Graded acceleration up to a desired feedrate F, or deceleration e.g. to a give point, may be obtained by a register that increases, or decreases, #F in steps.
