Title: Improvements in or relating to animal traps
IPC: A01M23/34
Filed: 1932-05-27
Abstract: 397,268. Animal traps. PHELPS, R. M., 88, Sid-well Street, Exeter. May 27, 1932, Nos. 15035 and 18118. [Class 5 (i).] In an animal trap of the kind comprising a movable tiller, a bow spring, a noose operatively connected to the ends of the bow spring, and means for throwing the noose upwards when the tiller drops and the spring is released, so that the noose grips the limb of the trapped animal, the bow spring is not attached to the tiller or tiller support so that when the trap is sprung, the spring and noose may be readily removed from the tiller and its support by the animal. The tiller a, pivoted at d, is mounted, Fig. 1, within a box-like casing k provided with a finger hole l and folded over at m to form a stop for the tiller. The noose chain s is anchored at one end by means of a ring u and stake v and is passed through rings r provided at the ends of the bow spring p and round the tiller casing, a split ring t being provided to adjust the size of the closed noose loop and a flexible or resilient covering x such as rubber tubing being provided at the other end of the chain to lessen the force of impact on the limb of the animal. The ends of the bow spring are retained, in the set position, between a cross-bar e and pawl h, the latter being pivoted to an extension f of the cross-bar and engaging a nose b on the tiller. When the trap is sprung, the noose is guided upwardly by guides n pivoted to the tiller casing, the rotary movement of such guides being limited by stops o. Fig. 3 shows a modified form of spring in which two loops r are provided at each end. In a further modification, Fig. 4, the tiller is secured to the casing by a pivoted strut 10, the drop of the tiller being, in this case, uniform all round ; a pivoted bar 11 engages the noose to lift it upwardly, when the trap is sprung.

Title: Improvements in systems for remotely controlling angular motion
IPC: G05D3/14
Filed: 1939-05-22
Abstract: 529,638. Coarse and fine Selsyn systems. TENNANT, W. J. (Anschutz & Co. Ges.). May 22, 1939, No. 15197. [Class 40 (i)] In a Selsyn system involving coarse and fine transmitters 101, 111 operated for example by a master compass, the outputs of the receivers 103, 113 are applied in series to an amplifier 123 which energizes a two-phase induction motor 121 to drive the receivers into the position of correspondence. Preferably the " fine " receiver is strongly energized so that the amplitude of its output is changing rapidly in the neighbourhood of zero error, but to ensure that the fine signal does not overpower the coarse signal when it is of opposite phase, its amplitude is limited by a rectifier bridge 124 with short-circuited D.C. terminals as shown by curve b in Fig. 4. Preferably also the amplifier is saturated at a comparatively low signal amplitude so that although the torque of motor 121 changes rapidly in the neighbourhood of zero and 180 degrees error it is constant for intermediate errors as shown by curve Md. Where the same transmitter pair controls a number of receiver pairs, de-coupling resistors are included in series in the transmission leads to the individual receivers. Preferably the effect of these is increased by the provision of resistive loads connected directly to the common transmission lines, Fig. 7 (not shown). Specification 230,111, [Class 40 (i)], is referred to.
Patent GB-630388-A (GB)
Title: Improvements in the production of cellulose esters
IPC: C08B3/22
Filed: 1947-06-10
Abstract: Stable organic esters of cellulose having a very low content of combined sulphuric acid or other inorganic acid are prepared by esterifying cellulose in the presence of an inorganic acid catalyst, neutralizing all the free inorganic acid, injecting steam into the solution to raise the temperature to at least 60 DEG  C., acidifying the hot solution with a further quantity of inorganic acid and maintaining or further raising the temperature of the solution for a short time.  The free acid is then neutralized and the cellulose ester ripened at an elevated temperature to the desired acyl value. A compound of magnesium, zinc, aluminium or an alkaline earth metal is used as the neutralizing agent, the temperature of the steam heating may be from 60 DEG  to 90 DEG  C., the proportion of free sulphuric acid after the hot solution has been acidified is preferably less than 1 per cent, the ripening temperature may be about 100 DEG  C., and the amount of neutralizing agent added before the ripening may be more than that theoretically required to combine with all the free sulphuric or other inorganic acid in the solution. In an example, cotton linters are pretreated with a small quantity of sulphuric acid, water, and glacial acetic acid for about 2 hours at 25 DEG  C. and then acetylated with acetic acid, acetic anhydride and sulphuric acid at -10 DEG  C., a peak temperature of 40-50 DEG  C. being ultimately reached.  More than sufficient aqueous magnesium acetate is then added to neutralize all the free sulphuric acid and live steam injected into the solution until its temperature reaches 90 DEG  C.  Sulphuric acid in solution in acetic acid is then added until the solution contains 0.5 per cent of free sulphuric acid calculated on the weight of the cellulose starting material, and steam injection continued until the temperature rises to 100 DEG  C. The free sulphuric acid is then completely neutralized by aqueous magnesium acetate and the solution allowed to ripen at 100 DEG  C. When the desired acetyl value is reached, the solution is cooled rapidly to 35 DEG  C., and the ripened cellulose acetate precipitated, washed, and dried.  The process may be used for the production of cellulose propionate, butyrate, acetate-propionate, and acetate-butyrate.  Specifications 538,913, 568,051, 568,098 and 597,295 are referred to.
