Filed: 1967-07-18
Abstract: 1,179,314. Lirikwork; cams. A. Y. KIPNIS. 18 July, 1967 [18 July, 1966], No. 32847/67. Heading F2K. [Also in Division B3] A variable-throw crank comprises a crank arm 44 mounted on a pivot shaft 46, a slide 42 slidable along crank arm 44, a driving link 40, pivotally attached to slide 42, and an adjustable guide cam 50 which is engaged by a roller 70 carried by slide 42 in order to control the position of slide 42 along crank arm 44 in accordance with any desired function. A bearing 22 is eccentrically secured to the upper end of pivot shaft 46 and bears against a table 12 of a lens grinding machine, so that angular movement of crank arm 44 effects reciprocation of table 12.

The driving link 40 is attached to a gear segment 38 which is oscillated about a shaft 26 by a worm gear 36 driven from an electric motor 32. A table 24 carrying a lens blank 4 and drive 4<SP>1</SP> is attached to gear segment 38. A grinder 2, its drive 2<SP>1</SP> and feeding device 14 are mounted on ways 13 on table 12 which is urged by springs 18 into contact with the eccentric bearing 22.
Patent GB-610334-A (GB)
Title: An improved process for the manufacture of agglomerated refractory products
IPC: C04B35/00
Filed: 1945-12-07
Abstract: Refractory products are prepared by agglomerating grains of a refractory substance which has been fused and cooled normally with fines of a refractory material of greater pyrometric and chemical resistance than the grains.  The fines may be of a material which, when fused and cooled normally, has a softening-point higher than that of the grains, or may be of the same or different composition as the grains but cooled rapidly after fusion so producing a material of higher softening-point. The grains and fines may be composed of corundum and mullite, or the fines may be of corundum and zirconia.

Title: Improvements relating to temperature sensitive arrangements for cooking appliances
Inventor: JONES JOHN ROBERT
IPC: A47J37/08
Filed: 1963-08-22
Abstract: 1,095,935. Grilling and toasting apparatus. MORPHY RICHARDS Ltd. Aug. 13, 1964 [Aug. 22, 1963], No. 33254/63. Heading A4D. [Also in Division G1] In a cooking appliance, a temperature sensitive element which controls the cooking time is located at the end of a radiation guide which receives radiation from the heated foodstuff. As applied to an electric roaster the element H is suspended near the end of a tube F, whose end is closed by a concave mirror G focusing the heat entering the tube from the toast A, on to the element, which may be a thermistor, thermocouple or bunched coils of nickel wire &c. A further element I, of a similar type, is attached to the tube F, being arranged to compensate the response of element H for any changes of ambient temperature. The arrangement ensure that in operation the heat received by the element H is only that from the toast, and when the toast is removed a shutter is arranged to cover the end of the tube F to protect the element from the direct heat of coils E. The elements H and I are connected in the transistor amplifier circuit of Fig. 2 (not shown). The output of this circuit provides (at terminals 25, 26) a control signal, to switch off the current to heating elements E or to a relay &c. to terminate toasting by actuation of apparatus to raise the bread carriage D and remove the toast A. The transistors (T 1  and T 2 ) are supplied by a half-wave supply. If H is a thermistor, rising temperature causes its resistance to decrease and a condition is reached where the first transistor (T 1 ) is fully cut-off and the second (T 2 ) fully conductive and the control is operated. The effect of rising ambient temperature is to cause I to decrease in resistance and a voltage is produced to oppose the effect of H. In another embodiment (Fig. 3, not shown), the tube F is replaced by an L-shaped radiation guide (L) of e.g. quartz, which may be caused to rotate into an operable position against the action of a spring (P) mounted on arm (N), when the bread carriage D, to which it is attached by a link (Q), is depressed. Other applications include grills and ovens &c.

Abstract: 335,905. Friden, C. M. F. June 23, 1928, [Convention date]. Divided on 314,058. Ze roizing-mechanism. - In a calculating machine with two counting mechanisms loosely mounted on a common shaft, means are provided whereby rotation of the shaft in one direction resets the numeral wheels of one counter to zero and rotation in the other direction resets the numeral wheels of the other counter. As shown the totalizing counter and revolutions counter of a machine for the four rules are arranged on a shaft 83 and each numeral wheel has an inwardly projecting tooth co-operating in a known manner with a spring pressed ball seated in the shaft. Secured to one end of the shaft 83 is a collar 95, Fig. 1, against which abuts one end of a sleeve 96 loose on the shaft and carrying a disc 97 integral therewith having cut-out portions 98, 99 as shown in Fig. 5. Splined to the collar 95 is a spring-pressed clutch washer 102, Figs. 1 and 7, having a projecting tooth 104 and a, cam surface 105 for co-operation with the cut-out. portions of the disc 97. In one direction of rotation the tooth 104 is operative to drive the sleeve 96 and cause a cam disc 107, Figs. 1 and 3, thereon to rock sectors 108, 109 and the shaft 89 whereby the spring pressure on the usual detents is released to permit the wheels to be reset to zero. At the opposite end of the shaft 83 is a similar set of parts, viz., collar 95A, sleeve 96A, disc 97A, and clutch washer 102A so arranged that when the shaft 83 is rotated by the hand crank 93 in the opposite direction a cam disc 116, Fig. 2, rocks a lever 117 and a shaft 88 to release the spring pressure on the detents of the product totalizer and permit the wheels to be zeroized. Specification 272,174 is referred to.

Each lever 19 carries a double die 18 co-operating with a double punch 9 on a slide cam-operated from a shaft 25. The levers 19 are arranged to effect adjustment of the group of punches as a whole and also the pitch of the individual punches. In a modification the projecting apparatus is arranged above the punching device and the film is fed by a transverse movement of the lowest punch when in engagement with the punched hole in the film.
