Title: Toaster having toasting control for convenience foods
IPC: A47J37/08
Filed: 1972-06-06
Abstract: 1395536 Toasters SUNBEAM CORP 6 June 1972 [7 June 1971 ] 26345/72 Heading A4D An electric toaster for toasting bread or convenience foods (e.g. frozen foods), comprises: four heating units 31 defining a pair of toasting compartments; a lever 89 having an adjustment range for adjusting the total energy consumed by the heating units during each toasting operation; a lever 206 for changing the energy consumption rate of the heating units between a first level suitable for toasting bread and a second lower level suitable for toasting convenience foods, the toaster being characterized in that, when the lever 206 is in a position for selecting the lower level of energy consumption rate, the lever 89 is restricted to move over a lower part of its adjustment range. As shown, each of the heating units 31 includes respective lengths 53a, 53b of resistance wire supported on an insulating member 52. The lever 206 is movable between a point 210 (corresponding to a bread-toasting position) and a point 212 (corresponding to the convenience-food toasting position). When the lever 206 is at the point 212 a switch 104 having contacts 104a, 104b is opened and the resistance wire lengths 53b are shorted out. A projection 246 of the lever 206 engages the lever 89 to limit movement of the lever 89. Movement of the lever 89 rotates a cam 88 which adjusts the gap between contacts 117a, 117b of a switch 117 controlled by a bimetallic device responsive to surface temperature of the food being toasted. The bi-metallic device, Fig. 6 (not shown), comprises a bi-metallic strip (145a) joined to a further, compensating, bi-metallic strip (145b) to form a composite strip (145). The strip (145) is secured at either end and an operating lever (150) is attached at the join of the strips (145a) and (145b). The strip (145) is said to provide uniform toasting under varied conditions since the compensating strip (145b) is sensitive to ambient temperature. The toaster is provided with a carriage 63 which is moved downwards by means of a lever 79. Movement of the carriage to its lowered position engages a tab 66 with resilient strips 105a, 105b and closes contacts 102b, 103b, and contacts 102a, 103a to commence toasting. The carriage is secured in its lowered position by engagement of a latching portion 95a of an armature 95 with a latching member (76), Fig. 2 (not shown). The engagement of the latching member (76) may be released by upward movement of the lever 79. The carriage is released for upward movement at the termination of a toasting operation when the bi-metallic device closes switch 117. When switch 117 is closed winding 94 of solenoid armature 95 is energized to dis-engage the armature latching portion 95a and the latching member (76). A tension spring 74 biases the carriage to its upper position. Movement of the carriage is controlled by a dash pot mechanism 80. The toaster is provided with a pivotally-mounted crumb tray 48. When the carriage is in its upper position a heatconducting member conducts heat from the bimetallic device.

Abstract: 843,781. Electromagnetic relay. CARPENTER, R. E. H. Aug. 20, 1957 [Aug. 31, 1956], No. 26744/56. Class 38 (5). [Also in Group XXV] Pivotal means for a relay armature comprises two coaxial bearings 103 having tapered surfaces engaging pins 102 attached to the armature 16, and mounted on plates 104a, 104b, at least one of which is resilient to bias the bearings axially. In the relay construction shown, which is similar to that of Figs. 7 and 8 of Specification 809,441, the plate 104a is comparatively unyielding but the plate 104b has two slots 110 to provide three limbs of which the centre limb 112 carries the bearing 103 and the outer limbs 111 are secured to the frame by screws 105 passing through outsize holes in the limbs to allow of proper centring of the armature during assembly. The bearing 103 extend so as to surround the ends of the cylindrical parts of the pin so as to retain them during rough treatment, and the centre of the bearing may be drilled so that the point of the pin protrudes into the hole (Fig. 5, not shown). The Specification refers also to tapered depressions in the armature itself, to ball or roller bearings interposed between the tapering surfaces (in which case one surface need not be tapered), to frusto-conical and part hemispherical tapered surfaces, and to bearings carried by circular diaphragms with circumferential ripples or spiral slots. Instead of the limb 112 being bowed outwardly, as shown, it may be initially lowered inwardly so as to be coplanar with limbs 111 after assembly.

Abstract: 1308570 Acoustic navigation INSTITUT FRANCAIS DU PETROLE DES CARBURANTS ET LUBRIFIANTS 19 April 1971 [15 April 1970] 26814/71 Heading H4D The distance and direction of a ship from a preselected position is determined by transmitting continuous acoustic waves from the ship to a group of transducers in the vicinity of the preselected position, detecting the phase differences in the waves received at pairs of transducers, converting the detected phase differences to a series of phase shift increments of constant magnitude and transmitting, as coded acoustic waves, the number of the increments to a counter on the ship.  In one embodiment the transducers are arranged Fig. 1 as shown by h 1  ... h 4  and their outputs are maintained at a constant value at the inputs to peak-clippers 6A ... 6D, Fig. 2. The ensuing signals are combined as shown in multipliers 7 ... 10 which eliminate H.F. components. The cosine (phase difference) signal at a multiplier output is fed to detectors 12, 13 which produce a pulse at one output terminal when the signal passes through zero amplitude in one direction and at the other output terminal when the signal passes through zero in the opposite direction, such pulses being coded by oscillators 141 ... 148 and respective gates 151 ... 158.  In another embodiment the transducers and signal combinations are arranged so that the equi-phase-difference pattern consists of sets of curves with equal intersection angles over a large surface in their vicinity, Figs. 6 to 8 (none shown). For greater accuracy a transducer arrangement as depicted in Fig. 9 may be utilized.

Abstract: 1,094,645. Tube expanders, necking, welding by fusion. F. FLEMING. July 7, 1964 [July 9, 1963], No. 27212/63. Headings B3J, B3Q and B3R. A tool for expanding and/or reforming a tube bore comprises tube engaging parts connected, in expandible or contractible array, to a plurality of linkages each comprising two links mounted on a common pivot in a tube engaging part and connected at their other ends to relatively rotatable coaxial members. The tool comprises a plurality, e.g. six segments 1, having a diameter when expanded approximately equal to the required diameter of the tube, connected by links 19, 20 with a pair of concentric rings 22, 21 via pins 25, 23 respectively, arranged on a common pitch circle. Each segment, which may have an anti-friction lining has a hole at one end and a slot at the other in overlapping relationship with each adjacent segment, a pin passing through one hole and one slot to link up with pairs of links 19, 20. Spacer rollers mounted on the pins 23 co-operate with the lower flange of the ring 22 to maintain the rings concentric and free to rotate relative to each other. Two diametrically opposed segments are connected by a turnbuckle 31 which when rotated moves the segments apart, this action causing the links 19, 20 to pull tangentially on the rings 22, 21 to rotate them relatively in opposite directions and distribute the expanding force via the remaining links equally between the segments. A manual or power operated turnbuckle, hydraulic or pneumatic jack or means to relatively rotate the rings to effect expansion of the segments may be used. The segments may assume any required shape, e.g. to suit the expanding of a polygonal cross sectioned tube. The tool may be used to coaxially align tubes of the same or different diameters e.g. to facilitate joining thereof by welding or other means. The rings may have extensions which extend clear of the tube bore to facilitate the application of the expansion means. A modified form of the tool in which the rings are of a larger diameter than the segments may be used to compress and/or shape a tube externally. The segments may be externally flanged to support loose wire coils or strip.

Abstract: 1,088,935. Crimping yarns; stop-motions. JOHN HEATHCOAT & CO. Ltd. June 2, 1965 [July 2, 1964], No. 27380/64. Headings DID and D1F. In a crinkling operation, thermoplastic fibre yarn Y, Fig. 1, supplied from a creel 1 passes through a tensioner 2 and a guide 3 to a feed roller 4, thence to another guide 5, over an oiling roller 6 and around a crimping head C which the yarn enters and leaves through guides 7 and 8. The head C, Fig. 2, comprises a circular row of sinker blocks 14 and sinker elements 15 each pivotable between open and closed positions in which its free end is disengaged from, or occupies, a corresponding space between blocks 14. Cams 17 and 19, Fig. 2, engage the elements so that, as the head rotates, each in turn is open at a first angular position of the head to permit the yarn to be introduced between the elements and the blocks and is then closed to entrap the yarn, and subsequently opened to release the yarn at a second angular position of the head. The yarn is set in the deformed or crinkled configuration by heating from a temperature controlled electric element 33. The cam 19, Fig. 9, is mounted on an arm 23, adjustably supported in slides in the head, by means of a rod 27 received in a bore in a mounting 29. Whenever the space between the open elements 15 and the blocks 14 is occupied by too much yarn, the cam rocks, against the action of a spring 21, and, if an adjustable amount of free travel (as determined by a set screw 31) is exceeded, this causes an electric contact 30 to close a circuit (not shown) to disengage the driving clutch of the machine.

Title: Improvements in liquid dispensing apparatus
Inventor: SPALDING ROBERT GEORGE
IPC: B67D7/08
Filed: 1952-10-31
Abstract: 735,066. Counting apparatus. WAYNE TANK & PUMP CO., Ltd. May 20, 1953 [Oct. 31, 1952], No. 27485/52. Class 106 (1) A liquid dispensing apparatus, such as a petrol pump, comprises irreversible volume counting drums 6, an indicating hand 4 geared to turn with the drums and making a single rotation for each unit dispensed, and a uni-directional clutch in the drive from the metering mechanism to permit the drums and hand to be rotated forwardly during resetting whilst ensuring a substantially positive drive during dispensing. In the apparatus shown, the drums 6 and hand 4 are duplicated on either side of the apparatus, and pivoted shutters 45 obscure the drums during resetting to obviate fraudulent advance of the drums by the operator. The meter shaft 12 drives a shaft 17 and gear 18 through a ball clutch 15, the gear 18 drives a gear 21 and shaft 22 through an idler 19, whence the units drums 6 are driven through idlers 24, 241. The gear 18 also drives the pointers 4 through gear trains 26-32 and 26<SP>1</SP>-32<SP>1</SP>. Resetting is effected by manually turning a shaft 20 on which the idler 19 is freely mounted, the rotation of shaft 20 being transmitted through gear trains 63-67 and 63-67<SP>1</SP> to the reset-shafts of the counting drums, the pointers 4 moving with and being reset by the two lowermost drums. During resetting, the input member 40 is clamped by a yoke 57 (Fig. 5), in order to prevent back drive to the meter shaft 12. The shutters 45 (Fig. 3), are interconnected by a link 46 and one is coupled to an actuating lever 47 pivoted at 48. A stud 53 on the actuating lever engages a rocking cam 52 bearing a stud 51 normally engaged in a notch 50 in a disc 49 on the reset shaft 20. Upon initial rotation of shaft 20 during resetting, the stud 51 rides out of the notch 50 on to the periphery of the disc 49, the cam 52 is rocked counterclockwise and the shutters 45 are lowered to mask the counter drums 6. During further rotation of shaft 20, a cam 70 thereon rocks a yoke 72 counterclockwise (Fig. 3), a latch 78a then holding the yoke. A stop 76 is thereby rocked counterclockwise (Fig. 5), through a connection 75 with a pin 74 on the yoke, so as to arrest the shafts 17 and 22 in their zero positions by engagement with abutments, as 77, on the gear 23 and an arm 78 on shaft 17. When the zero position is reached, the stud 51 drops back into the notch 50 and the shutters 45 are restored, the cam 52 trips the latch 78a to release the yoke 72 so that the abutment stops 77 are withdrawn to permit renewed operation of the counters. Pending release of the shaft 20 and its final small reverse rotation to the position shown, further forward rotation is prevented by engagement of the nose 83 of the yoke with the step 82 of the cam 70.
