Title: Improvements in or relating to distributors for planting machines
IPC: A01C11/02
Filed: 1953-05-13
Abstract: 730,927. Planting seedlings. RIBOULEAU, E. A. H. May 13, 1953, No. 13393/53. Class 6 (1). A seedling-planting machine comprises a vertical rotary star-wheel 1 carrying seedling- grippers, Fig. 7, which are opened in sequence by a cam 4 to deposit the seedlings, each gripper being associated with a gravityactuated catch which maintains it open after the opening by the cam. Each gripper comprises an upper member 8 integral with a pin 5 carried rotatably between lugs 6, 7 on the wheel 1, and a lower member 16 carried by a lever 12 pivoted at 13 on the wheel 1 and having an enlarged portion 15 forming part of the catch and being confined within a slot 18 on the wheel 1. The pin 5 has integral lugs 9, 10 and is encircled bya torsion-spring 11 tending to close the member 8 on to the lower member 16. This is prevented by contact between the lug 9 and the heavier end 15 of the lever 12. The operator, when charging the grippers, releases the lug 9 by digital pressure on the member 16 whereby the seedling is gripped between the members 8 and 16 until the cam 4 contacts the lug 10, causing release of the plants at the point of deposition. During subsequent rotation, the pin 5 is prevented from revolving by contact between the lug 10 and a sector 3 adjacent to the cam during which time the heavy end 15 of the lever 12 tilts it about the pivot 13 to contact the lug 9 and again maintain the gripper open.

Title: Defrost control means for refrigerating systems
IPC: F25D21/02
Filed: 1967-03-22
Abstract: 1,142,410. Defrosting. RANCO INC. 22 March, 1967 [10 May, 1966], No. 13557/67. Heading F4H. [Also in Division G1] A refrigeration system in which air is forced over the evaporator is defrosted in response to a change in the relative resistances of two selfheating resistors, which change occurs when the air flow rate falls because of frost accumulation on the evaporator. As shown, the resistors 81, 82 are connected in a circuit which includes a D.C. source 62 and the solenoid 54 of a doublethrow relay switch 55, the latter being adapted to energize either a reversing valve 44 for hotgas defrosting or the air circulating fans 36. Solenoid 54 forms part of the output circuit of an amplifier including a PNP transistor 67, the input of the amplifier comprising an NPN transistor 71. The base of the latter is connected to a junction 83 which is normally connected via a switch 92, also controlled by solenoid 54, to the junction 80 between resistors 81, 82. Resistors 81, 82 are respectively exposed to and shielded from the air flow so that the resistance of 82 is normally substantially greater than that of 81 and the base of transistor 71 is negatively biased so that it is held off. Junction 83 is also connected via diode 96 and rheostat 90 with a thermistor 91 which is in contact with the evaporator and has a resistance which decreases on rise in temperature. As the air flow rate falls, resistor 81 breaks up, junction 80 and the base of transistor 71 become more positive and transistors 71 and 67 turn on. Solenoid 54 is thus energized and causes switch 55 to initiate defrosting and switch 92 to move to contact 94 so putting resistances 84, 85 in parallel and increasing the forward bias on the base of transistor 71. When the evaporator temperature increases as a result of completion of defrosting the resistance of thermistor 91 is sufficiently small to cause negative bias at the base of transistor 71 so that transistors 71, 67 turn off and switches 55, 92 return to their original positions. Initially the resistance of thermistor 91 remains sufficiently small to maintain the negative bias on transistor 71 and so prevent resistors 81, 82 from initiating a false defrost cycle. The refrigeration system is incorporated in an open-front display case (Figs. 1 and 2, not shown) and resistors 81, 82 are located in bores in an insulating block located in an air flow duct downstream of the evaporator, the bore accommodating resistor 82 being closed at its downstream end (Fig. 6, not shown).
Patent GB-384901-A (GB)
Title: Manufacture of yellow mordant dyestuffs
IPC: C09B57/08
Filed: 1932-05-12
Abstract: Naphthalene dyes are derived by reacting a 4- or 3-aminonaphthalene-1 : 8-dicarboxylic acid or a sulphonated derivative thereof (or the corresponding acid anhydride) with an aminosalicylic acid or a homologue or substitution product thereof.  The products may be condensed by boiling together in aqueous suspension, but preferably a condensing agent, such as an alkali bisulphite, is present.  Since the nitro group of a nitronaphthalene-1 : 8-dicarboxylic acid can be reduced to an amino group by means of bisulphite with simultaneous introduction of a sulpho group, the same products may also be derived by condensing a 3- or 4-nitronaphthalene-1 : 8-dicarboxylic acid, an aminosalicylic acid and a bisulphite together.  A sulpho group is preferably present in one or other of the components in order to obtain good solubility.  The products are fast yellow mordant dyestuffs which can be used in colour discharge printing processes involving reduction on account of their resistance to reducing agents such as hydrosulphite.  In examples: (1) p-aminosalicylic acid is condensed with 4-aminonaphthalene-6-sulpho-1 : 8-dicarboxylic acid (or anhydride) in presence of sodium bisulphite; the product yields green-yellow shades on chrome-printed cotton and can be used in reduction colour discharge printing: (2) p-amino-m-cresotinic acid is condensed with 4-aminonaphthalene - 6 - sulpho - 1 : 8-dicarboxylic acid in presence of bisulphite to give a yellow mordant dye; the p-amino-o-cresotinic acid may be similarly condensed or with a sulphonic acid of 3-aminonaphthalene-1 : 8-dicarboxylic acid, and 2-oxy-3-aminobenzoic acid may likewise be employed: (3) p-amino-o-sulphosalicylic is condensed with 4-aminonaphthalene - 1 : 8 - dicarboxylic acid in presence of bisulphite; the product, when used with chromium mordant in colour discharge printing, yields fast resistant shades; (4) 4-nitronaphthalene - 1 : 8 - dicarboxylic acid is condensed with p-aminosalicylic acid in presence of bisulphite. Specification 299,721, [Class 2 (iii), Dyes &c.], is referred to.  4 - Aminonaphthalene - 6 - sulpho - 1 : 8 - dicarboxylic acid (or anhydride) is prepared by nitrating naphthalic anhydride, reducing the 4-nitro derivative, and sulphonating.  p-Amino-o-sulphosalicylic acid is prepared by sulphonating p-nitrosalicylic acid and reducing.
