Title: Improvements in or relating to apparatus for testing the cold flow of cheese, or other substances possessing rheological properties
IPC: G01N11/10
Filed: 1945-12-17
Abstract: 605,172. Testing rheological properties of cheese etc.; indicators. PACKMAN, P. J., and GUARD, R. F. W. Dec. 17, 1945, No. 34137. [Classes 106 (ii) and 106 (iv)] Apparatus for testing the cold flow of cheese, bitumen, waxes, confectionery, &c., comprises a base or datum surface 10 to rest on the cheese, a movable indenter 11, 13 adapted to be pressed into the cheese under an applied load, and a dial indicator 27 connected to the loading means to measure the degree of penetration of the cheese by the indenter and the degree of recovery of the cheese. The base has two brackets 15, 16 thereon, a lever 18, bearing on a roller 19 mounted at the head of the indenter 11, being pivoted in the bracket 16, and a twoarmed lever 22 being pivoted in the bracket 15. The arm 18 has an extension 25 operating on the spindle 26 of the indicator 27, and is provided with a roller 20 adapted to be engaged by a cross-bar 21 of the lever 22 which depresses the indenter 11 through the arm 18 under the influence of a weight 24 on the lever 22. A plate spring 29 partially counterbalances the weight of the arm 18 and indenter 11, but allows the latter to remain in contact with the cheese when the lever 22 has been raised. Means to hold the lever 22 in the raised position comprises a crank 38 riding beneath one arm of the lever and mounted on a counterbalanced arm 36 pivoted at 35 in an upright 28 on the base 10. In a modification, the apparatus is in a casing on which the cheese &c. is placed, and an indenter is projected upwardly from the casing into the cheese. A lever pivoted intermediate its ends is forked at one end to engage a cross-pin on the indenter and is adapted to be weighted at the other end by a weighted pivoted frame controlled by a crank handle. In use, the depth of penetration in a certain time, and the degree of recovery of the cheese in a certain time, are related to one another as a numerical factor. The dial indicator 27 has a fixed or adjustable scale and a movable pointer, and an additional scale or cursor comprising a transparent cover 33 carried in a rotatable bezel, this second scale being adjusted to the position of the pointer after penetration and having a reversed scale to show directly the degree of recovery of the indenter.

Title: Improvements in or relating to electric switches
IPC: H01H13/56
Filed: 1936-12-18
Abstract: 487,342. Snap - action switches. BRITISH MECHANICAL PRODUCTIONS, Ltd., COOK, C. R., and DEAKIN, S. T. Dec. 18, 1936, No. 34902. [Class 38 (v)] A switch, wherein successive operations in one direction of an operating member which moves in a substantially rectilinear manner cause the contact element alternately to open and close the switch by engaging one of two abutments and moving them in opposite directions to present them for alternate engagement by the operating member is arranged for mounting in the skirting board, has mechanism carried by a metal chassis 1, 2, 3 and enclosed in a case 35, 36 and is operated by downward pressure of the foot on a plunger 9 against a return spring 10. Fixed contacts 11 mounted upon an insulating plate 12 carried by a tongue 13 of the chassis are engaged by moving contacts 4 carried by a U-shaped member 19 as shown in Fig. a diagram of the link and toggle mechanism only. In the open position of the switch a flange 25 of the plunger 9 engages a hook 24 on the right-hand member 6 of a system of four pinjointed links 5, 6, 7 and 8, the lowest member 8 of which is pivotally mounted at 21 to the chassis and has pivoted to it a rod 18 which carries a compression spring 27 and is slidable through the base of the member 19. The three members 18, 19 and 27 form a dead centre snap-action mechanism so that when plunger 9 is depressed the link 6 moves down substantially parallel to link 5 which moves up, and the pin 20, moves past the pivot 17 carrying the member 19, which moves over to carry contacts 4 into engagement with contacts 11 with a snap action, positive initiation of this movement being given by arms 28 extending from the pivot 21 acting on shoulders 29. The force exerted by spring 27 in conjunction with the effect of the co-operation between link 6 and a lug 40 on link 8 then causes engagement of hook 23 on link 5 with the flange 25 when the plunger is released, the curvature of the link edge 26 against which the flange 25 slides, minimizing the shook of this action. Opening of the switch with a snap action is now effected in a similar manner by the next depression of the plunger 9, and a position indicator 38 is operated by the lateral movements of links 5 and 6. The switch also has a three pin socket with an interlocking shutter as described in Specification 487,063, [Group XXXVI].

Title: Analysis of Gaseous Mixtures
IPC: G01N31/12
Filed: 1966-08-04
Abstract: 1,153,821. Combustion analysis. PERKIN-ELMER CORP. 4 Aug., 1966 [20 Aug., 1965], No. 35022/66. Heading B1X. [Also in Division G1] A method of quantitatively analysing an organic substance for carbon, hydrogen and nitrogen comprises burning a sample of the substance in the presence of oxygen in a combustion tube 14 to produce a gaseous mixture of combustion products which is trapped in a reservoir 52 at a known temperature and preselected superatmospheric pressure, a portion of the mixture from the reservoir being passed to atmosphere successively through cells 74, 80, 86 for measuring water, carbon dioxide and nitrogen respectively, each of the cells including a sample chamber 74a, 80a, 86a, and a reference chamber 74b, 80b, 86b, the component being measured by each all being effectively removed from the mixture as it passes between the sample and reference chambers thereof, and the thermal conductivity of the mixture being compared between the sample and reference chambers of each cell to indicate the amount of water, carbon dioxide and nitrogen respectively in the sample. In carrying out an analysis, the sample is burnt in a boat 18 introduced into the combustion tube 14 by way of an openable end 16 after the whole apparatus has been purged by a carrier gas such as helium from a tank 30. The sample is heated by coil 22 and oxygen is admitted from a tank 36. The sample burns and the gases pass through an oxidising agent 20 (copper oxide or cobaltous oxide) and then to a reduction tube 42 containing copper. The gaseous mixture then passes into the reservoir 52 which is provided with a pressure switch to close a valve 46 when a predetermined superatmospheric pressure has been reached. The reservoir 52 and cells 74, 80, 86 are contained in a constant temperature enclosure 12. The sample from the reservoir 52 is then allowed to pass under the action of the pressure in the reservoir, through a delay volume 64 and successively through the cells 74, 80, 86 to a vent 90. During this step some of the mixture escapes through a vent 70. Subsequently the gas in the delay volume 64 is caused to pass through the measuring cells using helium carrier gas from a line 94, so as to reach a steady state in the sample and reference chambers of the cells. The cell 74 has a trap 76 containing e.g. magnesium chlorate to absorb water vapour in the mixture as it passes from the sample chamber 74a to the reference chamber 74b. The thermal conductivities of the gases in the chamber 74a, 74b is compared using thermistors or hot filaments connected in a bridge circuit and coupled to a recorder 104. The cell 80 has a carbon dioxide trap 82 containing e.g. soda asbestos or lithium hydroxide. In the cell 86 the thermal conductivity of the gases remaining after removal of water and carbon dioxide is compared with that of the carrier gas from a line 92, and this gives the nitrogen content. The valves shown in the apparatus may be operated manually or automatically and in the correct sequence by use of cams.
