Patent GB-772410-A (GB)
Title: A process for preparing aliphatic dicarboxylic acids and the resulting acids
IPC: C07C51/34
Filed: 1955-10-27
Abstract: A saturated aliphatic dicarboxylic acid is prepared by heating a solution of an ozonide of a cyclic olefin in the presence of water and with simultaneous introduction of oxygen or an oxygen-containing gas.  An oxidation catalyst, such as potassium permanganate, chromium oxide, manganese oxide or cobalt oxide, may be present, preferably in an amount of 0.1 per cent based on the cyclic olefin.  The solution of the ozonide may be the reaction mixture obtained in ozonization of the olefin.  Any organic solvent for the olefin and the ozonide which is inert to the ozonide may be used.  Ethyl acetate is preferred. The ozonization is usually effected at 0 DEG  C. or lower, but may also be effected at room temperature.  Any cyclic olefin having one, two or more double bonds, may be used as starting material. Hydrocarbon mixtures containing said olefins are also suitable.  In an example, cyclohexene is ozonized in ethyl acetate at 0 DEG  C. and the reaction mixture is heated with excess water at 100 DEG  C. in the presence of potassium permanganate with the introduction of oxygen to give adipic acid.  The production of glutaric acid from cyclopentene, and succinic acid from cyclo-octadiene, is mentioned.

Title: Improvements in or relating to latches and hinges for doors and the like
IPC: E05D15/50
Filed: 1936-11-12
Abstract: 480,974. Door fastenings and hinges. PAGE, C. W., and DUFFIELD, J. F. Nov. 12, 1936, No. 30854. [Classes 44 and 65 (ii)] Relates to combined hinge and fastening arrangements of the kind allowing a door to be opened about either edge, and provides an arrangement particularly suitable for the doors of motor vehicles in which fastening occurs automatically on closing the door. Fig. 4 shows a pair of bolts M near each vertical edge of the door, the bolts of each pair being connected to a corresponding disc F on the spindle of an operating handle (not shown) rotation of which simultaneously retracts the bolts from keepers K against the action of springs, such as N, serving to shoot the bolts. Each disc F has a shallow notch R and a deeper notch M<1>, Fig. 6. Co-operating with each disc is a sliding plunger G biassed by a spring H so that, when the door is opened, the plunger is projected from the free edge of the door. Rotation of a disc F to open the door brings notch R into line with a shoulder L<1> on the corresponding plunger. Projection of the plunger from the open edge of the door allows the shoulder to engage the notch and retain the bolts in retracted position. Slidably mounted on the door is a bar J having its ends normally in line with the notches M<1> as shown. Rotation of a disc F in opening the door causes that disc to displace bar J by cam action so that its other end engages notch M<1> in the adjacent disc F and prevents accidental release of the bolts K at the hinge edge of the door. On closing the door, the projecting plunger is forced inwards by a striking plate S, releasing the parts and allowing automatic return to the locking position shown. Bolts M and keepers K may have co-operating bevels to facilitate engagement. A modification is described in which the hinge fastenings comprise fixed hinge pins B, Fig. 3, engaged by hook-like members on the door, and held in engagement by spring-shot bolts C retractable by cables E connected to discs F.

Filed: 1975-07-24
Abstract: 1521891 Function generators NIPPON VICTOR KK 24 July 1975 [28 July 1974] 30967/75 Heading G4G [Also in Division H4] A complimentary distorter for predistorting a signal to be recorded on a disc by a cutter is based upon the theoretical premise that the portion of a stylus for replaying the finished disc is of circular form and radius r but approximate to a parabola where it touches the groove walls, and the equation of a parable is used to solve certain equations' An input signal f(t) is manipulated to produce a signal at a disc cutter where f<SP>1</SP>(t) and f<SP>11</SP>(t) are the first and second order differentiated signals and V is the linear velocity of the disc cutter relative to the disc. An amplitude limiter ensures that Coefficient a is approximately 0.57/r where r is the radius of the replay stylus. A voltage 2 V<SP>2</SP> a is obtained by producing from movement of the cutter head a voltage proportional to the square of the distance of the cutter from the centre of the disc. As the cutter head holding arm moves from the outer periphery of the disc inwardly a projecting member fixed thereto successively trips microswitches to bring in different resistors and drive a voltage corresponding to 2 V.<SP>2</SP>a (Fig. 11, not shown). The required signal at the cutter is obtained by a circuit shown by block diagram in Fig. 12 and in detail in Fig. 17 (not shown). The input signal f(t) after passage through an operational amplifier (70), Fig. 17 (not shown) is applied to a first differentiating circuit 52 (an operational amplifier) to produce signal f<SP>1</SP>(t). This signal is passed through two operational amplifiers (71. 72), Fig. 17 (not shown) and to a squaring circuit 53 (a multiplier in Fig. 17) to produce a signal {f<SP>1</SP>(t)}<SP>2</SP>. A second differentiation circuit 55 (an operational amplifier) is supplied with the signal f<SP>1</SP>(t) after passage through the operational amplifier 71 and produces signal f<SP>11</SP>(t). An amplitude limiter 56 (a pair of oppositely directed diodes) ensures that the condition | 2V.<SP>2</SP>a | > |f<SP>11</SP>(t)| will always be maintained. A subtraction circuit 57 (an operational amplifier) produces an output signal {2V.<SP>2</SP>a-f<SP>11</SP>(t)}. A division circuit 54 (a divider) produces a signal {f<SP>1</SP>(t)}<SP>2</SP>/2V<SP>2</SP>a-f<SP>11</SP>(t) as output. This is applied to an operational amplifier (74), Fig. 17 (not shown). Its output is supplied to an addition circuit 51 supplied with the original signal f(t). Signal f(t) and distortion signal {f<SP>1</SP>(t)}<SP>2</SP>/{2 V.<SP>2</SP>a-f<SP>11</SP>(t)} are added in a proportion of 2 to 1.
