Title: Improvements in and relating to the measurement of stickiness and firmness
Inventor: CRISP DONALD EDWARD
IPC: G01N19/04
Filed: 1955-03-14
Abstract: 791,947. Testing firmness and stickiness &c. of pasty materials. PETFOODS, Ltd., [formerly CHAPPIE, Ltd.]. March 14, 1956 [March 14, 1955], No. 7407/55. Class 106 (2). The firmness of a material, e.g. luncheon meat, animal foods, &c., is determined by allowing an impactor 17 to strike the surface of the material at a predetermined velocity and measuring the rebound, the surface of the material being covered, e.g. with a sheet of cellulose acetate, to remove the stickiness. By repeating the test with the surface uncovered and comparing the readings a measure of the stickiness is obtained. For testing the firmness the amount of penetration can be determined instead of the amount of rebound. A penduhun 16 pivoted at 14 carries a steel sphere 17 adapted to strike the material in ah opened can 19 clamped on its side on a vertically adjustable platform 20 by a plate 24 engaging the upper surface of the can and clamped by a screw 27. The arm 16 is swung upwards to a predetermined graduation on a scale 18, a spring latch 32 on the arm being lifted, until a slider 29 on an arcuate rod 28 has been passed. The arm is then released, the latch 32 rides up the inclined face of the slider without displacing it, and the sphere 17 strikes the material and rebounds. When the latch reaches the slider 29 it engages the flat face and moves the slider upwards to register the extent of the rebound. By performing the test several times the effect of the frictional resistance of the-slider can be overcome. The pendulum is raised to the same height for the tests with the material covered and uncovered, and the can 19 is moved between impacts so that the impact takes place at different regions. According to the Provisional Specification, for determining the depth of penetration the slider and latch are modified so that the latch moves the slider in the direction of penetration. The sphere 17 is first brought gently into contact with the surface while the latch is in contact with the slider, and the pendulum then released from a predetermined height, the difference in the positions of the slider being a measure of the penetration.

Filed: 1916-05-25
Abstract: 100.542. Jaeger, E. May 25, 1915, [Convention date]. Periodie-counter speed indicators. - Motion is conveyed from an engine or other shaft through wheels 5, 7, mounted on a sleeve 6, to a shaft 9 on which is mounted a toothed-barrel 10 driven by a slipping spring, the intermittent movement of the barrel being governed by an escapement. Secured to the barrel is a cam 21 provided with four projecting fingers 22 adapted to rock a.spring- controlled three-armed lever 23, Fig. 1, pivoted at 23<a> and having secured to one arm one end of a shaft 25, Fig. 4, this end being capable of oscillation in a slot in the main framing. The shaft 25 is driven from a wheel 8 in engagement with the wheel 7 and bears a fine-toothed wheel 27 brought by the oscillation of the shaft into and out of engagement with a similar wheel 103 on a shaft 29. Motion is conveyed to the indicating-shaft 34 through a pinion 31 on the shaft 29 engaging a loose wheel 32 provided with a pin 39, which moves a similar wheel 35 through a loose piece 37 on the shaft and a pin 38 on the wheel 35, this arrangement allowing the indicating-hand to make more than one revolution. Control of the movement of the wheels 32, 35 is effected by pawls 44, 45 adapted to engage the wheel 103 and a similar wheel 43 driven from the wheel 35. The pawls are caused to operate alternately on the wheels by the cam 21, Fig. 1, with which an arm 47 of a spring-depressed lever 48 engages. Return movement of the wheels 32, 35 is effected by spring-controlled sectors 50, 51 engaging pinions 33, 36 on the wheels, a flyer 30 on the shaft 29 serving to brake the movement. A zero stop for the shaft 29 comprises a pin 56, Fig. 2. on a slide 55, the pin co-operating with a stop 57 on the shaft 29, and the slide being moved into an inoperative position at the commencement of an engagement period by a slot 59, Fig. 1, in the sector 50 engaging a pin 58 on the slide 55. The Specification as open to inspection under Section 91 (3) (a) comprises also the provision of time indicating hands capable of being set to zero and with two revolution counters one of which may be zeroized daily. The minute and hour hands 61, 60 are driven from the shaft 9 through motion-work 68, 69, 70 between the wheels 63, 62. The pinion 70 is mounted on one arm of a rocking lever 78 which, when forced inwards by a push, disengages the pinion 70 and causes an arm of the lever 78 to strike heart-cams 80, 81 to return the hands to zero, the minutewheel 63 being frictionally mounted on its shaft. This subject-matter does not appear in the Specification as accepted.

Title: Continuously variable mechanical motion converter device
IPC: F16H35/02
Filed: 1974-02-19
Abstract: 1437901 Chain gearing J R HUMPHREY 19 Feb 1974 [7 Dec 1973] 7554/74 Heading F2Q A cam and linkage motion F, L, produces additive and subtractive components which are constant relative to an input motion over predetermined intervals for cyclic algebraic summation to a principal motion, means being provided to adjust the linkage to vary the ratio between the components. A chain 11 transmits a principal motion from a driving shaft 12 to a parallel driven shaft 13, cyclic variation being produced by axially sliding a carriage C carrying jockey sprockets 26, 27, around which pass opposite runs of the chain 11, which is guided by stationary idlers 21, 22, 23, one, 22, being adjustable for tensioning. The jockey carriage C is shifted axially through a lever L by a face cam F fast on the input shaft 12, the rise of the cam producing a constant speed addition to the mean principal speed, whilst the fall similarly produces a constant subtraction therefrom. The ratio between the additive and subtractive components is varied by shifting the fulcrum 42 of the lever L, from a zero position coincident with the carriage pivot 35, to a predetermined maximum, by screwing a shaft 44, as by a handknob K or motor. The drive is used for feeding a web in a printing machine. An example of four-to-one ratio-range in output speeds, or one including reversal of output, and with harmonic transition between the components, is given.

Filed: 1967-02-17
Abstract: 1,111,406. Semi-conductor devices. ITT INDUSTRIES Inc. 17 Feb., 1967 [18 Feb., 1966], No. 7627/67. Heading H1K. The capacitance of a variable capacitance diode produced by diffusing an impurity of one conductivity type into a semi-conductor body of the opposite conductivity type having a graded impurity concentration, is adjusted to a predetermined value by heating in an oxidizing atmosphere. A plurality of diodes are produced by growing an N-type epitaxial layer on a silicon substrate, oxidizing the surface and masking and diffusing-in phosphorus to produce a graded impurity gradient and then diffusing-in boron to form a plurality of junctions. The diffusion may be performed by the " powder diffusion " method using doped and powdered semi-conductor material as the impurity source. The capacitance of each diode is then reduced to the desired value by heating the wafer in an oxidizing atmosphere. This drives the boron further into the wafer without affecting the phosphorus distribution. A silicon dioxide coating is simultaneously formed. The contact areas are then exposed and electrode material is evaporated-on. The wafer is then diced and the individual diodes encapsulated. The semi-conductor material may also be germanium or a semi-conductor compound.

Filed: 1947-03-24
Abstract: 635,572. Electric clocks. INTERNATIONAL BUSINESS MACHINES CORPORATION. March 24, 1947, No. 7970.. Convention date, April 10, 1946. [Class 139] A secondary clock comprises an annular magnet coil surrounding a plurality of pole elements, an oscillating armature supported for rotary movement about the axis of the magnet coil and having a corresponding number of pole elements, arranged so that upon energization of said magnet coil the armature is rotated by the interaction of the pole elements, and biassing means constantly urging said armature against rotation which means return the armature to its initial position upon de-energization of the magnet coil, the oscillating movement of the armature being transmitted to a time indicating member. The magnet coil 27 is wound round a ring 28 in a U-shaped housing 26 the links of which are held together by bolts 14 passing through the front and back of the casing 10 of moulded insulating material. The confronting ends of the limbs of the housing 26 form opposed pairs of poles 38a, 38b, Figs. 1 and 2. The oscillating armature 40 is journalled on a sleeve 23 surrounding the shaft 24 carrying the minute hand 25 and has a central hub 41 and a circular rim 43 having flange elements 44 forming pole elements corresponding in number to the pairs of poles 38a, 38b. Upon energization of the coil 27 the poles 38a, 38b attract the adjacent poles 44 of the armature 40 which is thereby rotated. During this movement of the armature 40 a pawl 58 fixed thereto rides over the adjacent tooth of a four-toothed ratchet 55 which is prevented from movement by a detent member 62 pivoted on the armature 40. When the coil 27 is de-energized a weight 46 carried by a spring 47 fixed to the armature hub 41 returns the armature to its initial position where the weight 46 is stopped by a leaf spring 50. During the return movement of the armature 40 the pawl 58 steps the ratchet wheel 55 forward one tooth. The movement of the ratchet wheel 55 is transmitted through the gearing 55, 65, 66, 68, Fig. 5, to a gear wheel 69 on the minutes shaft 24. A spring detent 71 engages crown teeth 70 on the gear 66 to prevent backlash. The hours hand 75 is fixed to a sleeve 76 on a hub 77 having an arm 85 carrying a planet wheel 83 meshing with a fixed ring gear 81 'and pinion gear 80 fixed to the minutes the shaft 24. In order that the secondary clock may operate in a system such as is described in Specification 236,199, [Class 139], the gear wheel 69 has upon its rear face a cam surface 87 having two drops 98, 99 and co-operating with two contacts 93, 94 in such a manner as to control the reception of impulses from the master clock as disclosed in the above Specification.

Abstract: 407,197. Thermostats. NAAMLOOZE VENNOOTSCHAP MACHINERIEEN - EN APPARATEN FABRTEKEN, 30, Croeselaan, Utrecht, Holland. March 16, 1933, No. 8019. Convention date, April 22, 1932. [Class 64 (ii).] An apparatus for actuating a mechanically movable member 8 in response to variations in the intensity of radiated heat comprises a black strip 1 enclosed in a vacuum vessel 2 and directly connected to the member 8, and a second polished, but otherwise similar, strip 7 also connected to the member 8. The vessel 2 is highly evacuated in order to reduce the heat leaking from the strip 1 and to cause the radiant heat absorbed bv the strip to raise its temperature as much as possible above that of strip 7. As the strip 1 is sealed through the glass of vessel 2 at both ends, a bellows section 5 is provided to enable the vessel to vary in length with the strip. Instead of using thermal elements comprising strips expanding linearly, bimetallic strips may be used. Alternatively black and polished bulbs connected by a tube and containing a volatile liquid may be mounted on a balance beam. The higher temperature of the black bulb causes an accumulation of liquid in the polished one and thus the beam is tipped and the desired control actuated. The black body may be supported in the vacuum vessel by thin wires or on points. The vacuum vessel itself may be used as the comparison body 7.
