Title: A warning or trip device operable by an endless belt slipping on its driving pulley
IPC: B65G43/04
Filed: 1947-08-11
Abstract: 650,734. Screw pumps. NATIONAL COAL BOARD, and MAWSON, J. C. Aug. 11, 1947, No. 22263. [Class 110(i)] [Also in Groups XXIV and XXX] A warning or trip device operable by an endless belt slipping on its driving drum or pulley comprises a driven roller or pulley engaged by the belt and arranged to be rotated'thereby at a rate dependent upon the speed of movement of the belt, a rotatable member associated with the driven roller or pulley, means independent of the belt for driving the member in synchronism with the driven roller when the belt is moving without slip and means operable by relative movement between the driven roller and the member resulting from substantial 'slipping of the belt, for operating a warning device or a trip mechanism for stopping the driving drum or pulley. In the embodiment shown, a roller 1 engaged by a mine conveyer belt is rotatably supported by bearings 2 on a spindle 3 which is supported by bearings 6 and provided with a sprocket 7 rotated by a chain drive from the driving mechanism of the conveyer so as to rotate at the same rate as the roller 1 when the belt is running without slip. The interior of the roller is connected by pipes 11, 12 in the spindle and by passages 11b, 16, with an oil reservoir 15 and a cylinder 17 containing an operating plunger 18 for a mercury switch 21 controlling the conveyer drive mechanism. When substantial slip of the belt on its driving drum occurs, the roller 1 rotates at a slower speed than the spindle whereby a screw 10 on the spindle develops pressure in the oil within the roller 1 and this is transmitted through the pipe 16 to the cylinder 17 so as to raise the plunger 18 against its spring 18a and operate the switch 21. A needle valve 19 permits a slight now of oil back to the reservoir 15 to prevent pressure building-up in the cylinder 17 and thus allowing a moderate amount of belt slip without operation of the switch. The switch 21 may control an audible or visible warning device in addition or as an alternative to the operation of the means for stopping the conveyer.

Title: Diepoxides of cycloaliphatic esters
Filed: 1954-08-19
Abstract: The invention comprises diepoxides of the formula <FORM:0768157/IV(b)/1> wherein R1 to R6 each represent hydrogen or an aliphatic hydrocarbon radical.  The novel porducts may be obtained by epoxidizing a 3-cyclohexenylmethyl - 3 - cyclohexene carboxylate by means of the acetaldehyde monoperacetate method described in Specification 735,974, or by means of peracetic acid at -25 DEG  to 150 DEG  C., preferably 10 DEG  to 90 DEG  C.  The unsaturated cycloaliphatic esters may be prepared by subjecting cyclic unsaturated aldehydes to the Tischenko condensation in the presence of an aluminium alkoxide.  Such cyclic unsaturated aldehydes are produced by reacting butadiene or its homologues with a ,b -unsaturated aliphatic aldehydes, e.g. butadiene, isoprene, or 1,3-pentadiene with acrolein, crotonaldehyde or methacrolein.  In examples: (1) 3-cyclohexene aldehyde, (2) 1-methyl-3-cyclohexene aldehyde, and (3) 6-methyl-3-cyclohexene aldehyde are subjected to the Tischenko reaction in the presence of aluminium isopropoxide in benzene to give 3-cyclohexenylmethyl-31-cyclohexene carboxylate, and the 1,11-dimethyl, and 6,61-dimethyl derivatives thereof respectively.  In examples (4), (5) and (6), the above unsaturated cycloaliphatic esters are treated with peracetic acid in acetone, the mixture is stirred at about 20-40 DEG  C. and then stored at -11 DEG C. for 16 hours; the mixture is then added to ethyl benzene refluxing under reduced pressure whereby low-boiling materials are distilled off, leaving as product (4) 3,4-epoxycyclohexylmethyl - 31,41 - epoxycyclohexanecarboxylate and (5) the 1,11, and (6) the 6,61-dimethyl derivatives thereof respectively.  In Example (7), the Diels-Alder adduct of isoprene and acrolein is subjected to the Tischenko reaction giving an isomeric mixture of (3 or 4)-methyl - 3 - cyclohexenylmethyl - (31 or 41)-methyl - 31 - cyclohexenecarboxylates which on epoxidation with peracetic acid in acetone give an isomeric mixture of 3,4-epoxy-(3 or 4)-methylcyclohexylmethyl - 31,41 - epoxy - (31 or 41)-methylcyclohexanecarboxylates; in (8), the Diels-Alder adduct of piperylene and acrolein is similarly treated to give 2-methyl-3-cyclohexenylmethyl-21-methyl-31 -cyclohexenecarboxylate which is epoxidized with peracetic acid in acetone.  The products are useful as modifiers, plasticizers and stabilizers for synthetic resins and as intermediates in the production of materials for surface coatings, laminates and plastic moulding compositions.

Abstract: 971,953. Respiratory devices. BLEASE ANAESTHETIC EQUIPMENT Ltd. May 9, 1963 [June 15, 1962], No. 23218/62. Heading A5T. A respiratory device comprises a one-way exhaust valve 44 having its inlet in communication with an exhalation valve 42 and a passageway 46 through which gas is drawn and an admittance valve 52 biased shut and able to admit air to the passageway 46 when the bias is overcome, the device being such that when gas issues through the exhalation valve 42 at a rate lower than the rate at which it is drawn through the passageway 46 the exhaust valve 44 is closed and the pressure in the passageway 46 becomes subatmospheric, the maximum value of this subatmospheric pressure being determined by the bias on the admittance valve 52. On inflation of bellows 4 (which is biased shut by compression spring 8), by compressed air entering by inlet 6, needle 10 moves away from valve seat 12 and pivoted lever 14 comes in contact with movable stop 16 which opens valve 22. As bellows 4 collapse air is forced into bellows 18 and as bellows 18 expand bellows 48 expand. At this stage inhalation valve 36 is closed and the patient exhales through exhalation valve 42. Initially the rate of exhalation is greater than the rate at which gas is being drawn into bellows 48 and exhaust valve 44 is open to the atmosphere. When the rate of gas drops below that at which it is entering bellows 48, valve 44 closes and a subatmospheric pressure builds up in passageway 46 till the valve member 52 overcomes the bias of counterweight 56 to allow air to enter passageway 46. The pressure in the passageway 46 remains constant until the exhalation period is completed which is marked by contact 30 contacting movable stop 32 to close valve 22, by the closing of exhalation valve 42 and by the opening of inhalation valve 36 to permit bellows 18 to exhaust their contents to the patient. As bellows 18 deflate bellows 48 deflate, gas in bellows 48 escapes to the atmosphere through valve 58, and bellows 4 inflate to start another cycle.
