Title: Apparatus for use in calculating the food requirements of animals
Inventor: MATTINSON JAMES HUGH
Filed: 1921-01-10
Abstract: 172,236. Mattinson, J. H. Jan. 10, 1921. Calculating food rations for animals.-An apparatus to determine a suitable ration, in constitution and amount, for a farm animal in order to maintain it in fit condition for fulfilling given requirements, comprises a chart of three scales 1, 2, 3 and a number of groups of counters or checks A, A<2>, A<3>, B, B<2>, B<3>, &c. which correspond in their lengths with the quantities of nitrogeneous and starch materials and the unitary amount in the dry state of the various foodstuffs. The scales have different starting-points according to the weight of the animal, and the first two scales are graduated in terms of milk yield or other required results. To build up a ration for say a milch cow of 11 owt. expected to yield two gallons of milk daily, the groups of counters relating to the available foodstuffs are disposed as shown, each counter being superposed on its respective scale, and the counter groups being so chosen that the lines of counters of scales 1 and 2 terminate approximately at the 2-gallon graduation, and the total quantity of the dry food ends on Scale 3 somewhere between the minimum and maximum amounts essential for health.

Patent GB-899639-A (GB)
Title: Improvements in or relating to circuits comprising bistable magnetic cores
Inventor: WEBB HERBERT HENRY
IPC: H03K3/45
Filed: 1959-01-14
Abstract: 899,639. Circuits employing bi-stable magnetic elements. RACAL ELECTRONICS Ltd. Jan. 14, 1960 [Jan. 14, 1959], No. 1317/59. Class 40 (9). In a sequential arrangement of interconnected bi-stable magnetic cores CR1, CR2, &c., Fig. 1, at least each core after the first core may be switched from a first state to a second state by energization of its independently energizable input A, B, &c., only if the preceding core has first been similarly switched, and each core provides an electrical output signal when its core is switched from its first state to its second state. In operation, core CR1 is set to the first state by set windings (not shown) and all other cores are set to the second state. A pulse at input A reverses core CR1 and temporarily switches on the associated transistor to give an output at terminal A<SP>1</SP> while switching core CR2 to the first state. Core CR2 may then be switched to its second state by application of a pulse at input B. The winding connected to the transistor collector electrode provides regenerative feedback to improve the switching characteristic. The last stage may be connected to the first stage in a ring circuit. In a totaliser or chronomotor, Fig. 2, a " start " pulse applied to core 1 gives an output from its associated transistor which opens a gate and primes core 2. A subsequent " stop " pulse applied to core 2 gives an output which primes core 3 and which is used to close the gate and start a display timing circuit during which a count may be read off. An " end display " pulse applied to core 3 resets the totaliser to zero and primes core 1.

Title: Improvements in and relating to devices for the unidirectional transmission of torque
IPC: F16D41/22
Filed: 1953-01-17
Abstract: 776,741. One-way brakes. KELLNER, M. April 20, 1954 [Jan. 17, 1953], No. 1435/53. Class 103 (1). [Also in Group XXIV] A unidirectional clutch or brake 25 comprises an intermediate section consisting of two parts 39, 40 which frictionally engage an inner section 29 and which engage an outer section 27 by helical surfaces of opposite hands. Relative rotation of the sections 27, 29 in one direction causes the parts 39, 40 to approach one another and engage the friction faces and relative rotation in the opposite direction will release the pressure between the friction faces. The friction faces may be conical or plane or may be constituted by a multiplicity of discs. Stops or springs may be provided to control the relative movement at the helical surfaces. The intermediate and inner sections may have additional friction faces arranged so that the device may act in one or other direction of rotation as desired. The device may replace ratchets in feeding and traversing mechanisms of machine tools. As applied to a change speed gear, the members 27, 29 are carried by shafts 28, 30. A second device 26 has its inner member 36 on a sleeve 37 which is fixed to, or has limited angular movement relative to, a housing 38. The outer member 35 has internal teeth 34 meshing a compound pinion 32 on a pin 31 fixed to the member 27. The pinion 32 also meshes gear teeth on the shaft 33. The two devices 25, 26 are effective in opposite directions of rotation. If the shaft 28 drives device 25 engages and 26 disengages and the shaft 30 is driven at the same speed as the shaft 28. If the shaft 30 is the driver device 26 engages and 25 disengages so that the member 35 is held stationary and the shaft 28 is driven at reduced speed.

Title: Improvements in spectrographs
IPC: G01J3/40
Filed: 1940-01-26
Abstract: 539,324. Spectrophotometers. AMERICAN CYANAMID CO. Jan. 26, 1940, No. 1625. Convention date, Feb. 9, 1939. [Class 97 (i)] An absorption spectrophotometer comprises means for separating light from a source into two beams passing respectively through a test and a standard sample, a spectrograph, and means for recombining the beams at its entrance slit to produce on the plate a plurality of spectra from each beam in alternate juxtaposition, together with means in the test sample beam only to control the relative exposures of the separate test sample spectra. In the apparatus shown, light from a preferably line source 1 passes into a quartz prism 2 in optical contact with one face of a rhomb 4 in which is a vertical and central narrow groove 5 which causes a narrow reference beam to be reflected to a rhomb 7, the remainder of the light passing into the rhomb 4 to form a test beam which is reflected forwardly from the end face to a recombining prism 8. This prism is in optical contact with one end face of the rhomb 7, the contacting face being formed with narrow grooves having roughened or coated bottoms which cause the reference beam to be reflected forwardly to the spectrograph slit 6 and the test beam to be diffused or absorbed. At the intervening spaces in which the faces of the prism 8 and rhomb 7 are in optical contact, the reference beam is not reflected and passes out of the system, whilst the test beam passes forwardly through the interface to the spectrograph slit, on which both beams are focused by a cylindrical lens surface 2 on the prism 3. The image obtained in the spectrograph is thus formed of a series of narrow contiguous spectra formed alternately by the reference and the test beam. The reference beam passes through a standard sample 16, if the test sample is to be measured relatively to a standard, and then through a rotating sector 12 formed by two discs which are relatively adjustable to vary the width of the sector in order to vary the exposure of the reference beam. The test beam passes through the sample, for example a liquid in a quartz cell 17, and then by a compound stop sector consisting of a slowly rotating outer portion 18 and a rapidly rotating inner portion 19. The sector steps are designed to give logarithmically decreasing exposures to the successive spectra formed by the test beam. To avoid the necessity of accurately forming very short steps, those for the shorter exposures are formed on the inner portion 19 of the disc, which rotates seven times as fast as the outer portion 18, the steps on it being exposed through a sector 27 in the portion 18 occupying oneseventh of the circle ; the steps on the inner disc are thus effective only for one revolution in seven, and are made seven times the length they would otherwise occupy. Alternatively a step neutral wedge may be used for graduating the exposures of the test spectra. Reference has been directed by the Comptroller to Specification 393,648.

Patent GB-1111214-A (GB)
Title: Process for preparing semisynthetic penicilins
IPC: C07D499/00
Filed: 1966-01-13
Abstract: 6-Amino-penicillanic acids are acylated in the amino group by treatment with a cyanomethyl ester of the acylating acid.  The reaction is suitably effected in an organic or organic-aqueous liquid medium, such as pyridine, acetone, or tetrahydrofuran, in the presence of a catalytic heterocyclic base, such as 2-hydroxy-pyridine, pyrazole, triazole, imidazole or succinimide, by reacting a penicillanic acid salt of a secondary or tertiary amine with a molar excess of the cyanomethyl ester.  The product may be purified by extraction of by-products from its aqueous solution with ethyl acetate or ether at neutral or alkaline pH, followed by liberation of the acylated amine from its salt form by addition of acid, and extraction from the acidified aqueous solution with ethyl acetate or ether. The free acid is then precipitated from the solvent by addition of a base (e.g. triethylamine or ammonia) to give the solid salt.  Examples are given for acylation of 6-aminopenicillanic acid using cyanomethyl carbobenzoxyamino-acetate, and cyanomethyl alpha-carbobenzoxy-L-amino-beta-phenyl propionate.

IPC: B60T15/04
Filed: 1959-01-17
Abstract: 952,587. Compressed air brakes; valves. GIRLING Ltd. April 19, 1960 [Jan. 17, 1959] No. 1811/59. Headings F2F and F2V. A compressed-air system for actuation of the brakes on a vehicle comprises a compressor 10 and a reservoir 12 in which air is maintained by the compressor at a pressure considerably higher than the working pressure for the braking system, in combination with a reducing valve, arranged between the reservoir 12 and the brake cylinder 13, which serves to reduce the pressure of the air supplied to the braking system to the normal working value. As shown, the reducing valve is incorporated in the driver's control valve and comprises a spring 24 which is compressed, on depression of pedal 14, on to the top cup member 25 of a piston 26. In the position shown, the cylinder 13 is in communication with the atmospheric port 22 via ports 40, 29. This communication is interrupted on downward movement of the pedal 14 when the port 29 is closed by the valve seat 30 on the spool valve 31. Further movement lifts valve seat 34 from the port to admit pressure fluid from port 33 and when a predetermined pressure is reached in cylinder 13, it is communicated via port 40 to the lower side of piston 26 to lift it against the spring 24 and permit spring 36 to close the valve 34.

Title: Improvements in or relating to means for changing bobbin rails in spinning, twisting and like machines
IPC: D01H9/04
Filed: 1930-01-18
Abstract: 339,171. Benz, E. Stutz-. Jan. 18, 1930. Doffing-arrangements.-In spinning, twisting, and like machines of the flyer type, wherein duplicate bobbin rails are employed for doffing, two series of pivoted rail carriers are provided which are at the same height when in the spinning axis, but alternately at different heights in front of and behind it, so that a bobbin rail placed on one carrier is automatically transferred to the other carrier by swinging the two carrier arms from the front of the machine towards the back or vice versa. The bobbin rail b1, Fig. 3, containing full bobbins a1, is lowered by the spinning lift carrier c on to the carrier arm e. The second carrier arm f supports a rail b2 containing empty bobbins a2. The two carrier arms are connected by a link p, and are both swung to the, left until the empty bobbin rail is in the spinning axis. The rail b2 is raised by the lift carrier c, the full bobbins a, are exchanged for empty ones, the latch p disconnected, and the arm f allowed to fall forward as in Fig. 5. The shaft g is now rotated and the two arms turned to the right, thus the empty bobbin rail is transferred to the, arm f Fig. 7. The, arm e is now turned to the left until it is in the spinning axis, and the link p engages the pin on the arm f. Thus the initial position of Fig 3 is reached. The relative vertical movement of the two faces supporting the bobbin rail may be modified by providing eccentric bearings for the arms, or by mounting them on the ends of a double armed lever.

Title: Improvements in coin gauging and selecting mechanism, such as used in coin-freed apparatus
Filed: 1938-01-20
Abstract: 509,889. Testing coins. HARPER, P. S. Jan. 20, 1938, No. 1904. [Class 27] In a combined annulus and weight-testing device for coins having a pivoted counterbalanced coin carrier and a delay action device, the delay action device is operable by inserting a coin to control means for setting the coin carrier to a particular position after a predetermined time interval without actuating a movable hinged clearing wall of preliminary testing devices. A coin inserted in a slot 3, Figs. 1 and 2, actuates a delay action lever 14 which operates as described in Specification 425,024, and passes down a stationary shoot 4 provided with a bounce test as described in Specification 487,938 from which it is delivered by a shoot 7 to the combined annulus and weight testing carrier 8. This carrier, which operates as described in Specification 471,644, has annulus gauging points 12 to co-operate with a fixed stop 13 and an adjustable counterbalance weight 11 for testing the weight of the coins. The carrier, when released, moves to position A, Fig. 1, to receive a coin, which is delivered at a reject position B, if not of proper weight and thickness, or at position C leading to the coin-freed apparatus. When a coin is inserted, the delay lever 14 releases a double-armed lever 22 which holds a locking lever 23 in position to lock the carrier 8 in the reject position B by a notch 36 engaging a pin 37 on the carrier. A cam portion 24 on lever 23 also holds a weighted lever 26 carrying the stop 13 out of the path of the gauging points. When the lever 23 is released, the carrier moves to position A and the stop 13 is moved into the path of the points 12. If owing to the coin being light in weight, the carrier 8 stops between the. positions A and B, the return of the lever 14 after a predetermined delay rotates the lever 22 to move the locking lever 23 back to its initial position by acting on a lug 33 thereon. A cam portion 35 on the lever 23 engages the pin 37 and moves the carrier to position B. If the carrier 8 has moved nearly to position C, a deflector 39 on the lever 23 engages the pin 37 and moves the carrier fully into position C, the carrier being locked in this position by a second recess 40, until another coin is inserted. A sweeper 41 pivoted to the delay lever 14 is reciprocated over the bounce platform 5 to clear this platform. The testing device is constructed as an interchangeable unit.
