Title: Improvements in the manufacture and production of resinous products
IPC: C08G63/12
Filed: 1929-03-05
Abstract: 328,728. I. G. Farbenindustrie Akt.- Ges. Dec. 24, 1928, [Convention date]. Ester condensation products.-Synthetic resins are prepared by condensing adipic acid or its higher homologues containing a branched chain with a polyhydric alcohol, with or without a mono or dibasic carboxylic acid. The products are very plastic, and may be added to phthalic and glycerin resins to produce flexible products. As additional acids oleic and resin acids are mentioned. In the examples, (1) adipic acid and glycerin are heated at 160‹-165‹ C. for several hours, the A-resin thus formed being converted into the C-form by further heating at 160‹-180‹ C.; (2) a mixture of isomeric methyl adipic acids is heated with glycerin and boric acid at 160‹ C. Specification 317,225 is referred to.

Patent GB-1498166-A (GB)
Title: Aircraft ground proximity warning systems
IPC: G01C21/00
Filed: 1976-02-24
Abstract: 1498166 Ground-proximity warning system SUNDSTRAND DATA CONTROL Inc 24 Feb 1976 [6 March 1975] 07220/76 Heading B7W A ground-proximity warning system compares the rate of closure to the terrain signal hÀ R  with the aircraft's altitude signal h R  above the terrain to generate a warning signal when the closure rate is excessive for a particular altitude. The system modifies the altitude rate signal asymmetrically so as to reduce the tendency for terrain having a negative slope to build up a negative charge or bias on a complementary filter 12. This negative bias would tend to decrease the response of the system to a subsequent positive or rising slope. The system includes an altitude rate limiter 10 which limits the modified altitude rate signal to a first limit of fixed size and polarity when the aircraft is ascending relative to the ground and to a second limit of greater size when the aircraft is descending relative to the ground. The second limit may be constant or may increase with increasing altitude rate signal up to a predetermined value at which it becomes constant. The second limit may have a polarity opposite to or the same as the polarity of the first limit. The asymmetric characteristics of the rate limiter 10 is only necessary at relatively high aircraft speeds, and therefore the performance of the limiter is altered in response to a "flaps down" signal, which accompanies low aircraft speed, to impose equal limits on the size of the altitude rate signal. Two preferred rate-limiter circuits are disclosed.

Title: Improvements in Self Setting Sails or Blades of Windmills or of Tractor Screws or of Pusher Screws of Aeroplanes or Dirigibles.
Inventor: DRZEWIECKI STEPHANE
IPC: B64C11/34
Filed: 1918-04-30
Abstract: 124,935. Drzewiecki, S., and Rey, J. April 30, 1918. Blades &c.-Relates to self-adjusting screw blades for windmills and aircraft propellers adapted to allow a substantially constant speed to be obtained in spite of variations in the speed of the wind or the aircraft. A socket c mounted on the end of a shaft d carries in a transverse sleeve e a rod f freely pivoted therein and fitted at one end with the screw blade g and at the other end with a counterweight h. The weight h not only balances the centrifugal pull of the blade g, but, by reason of its inclination to the shaft, exerts a torsional action on the rod f opposite to, and greater than, that exerted by the blade g. This torsional action tends to increase the pitch of the screw and is effective only when it overcomes the opposite tendency of springs j, j<1>, stops k, L limiting the movement in each direction. The blade assumes an inclination the pitch of which multiplied by the predetermined speed corresponds to the speed of the wind or the aeroplane. In place of one counterweight, several may be used; Fig. 6 shows one weight M for balancing the centrifugal pull of the blade, and two N<1>, N<2> for producing the torsion couple. The position of these weights N<1>, N<2> may be varied; for example, they may be placed at N', N''. Screw devices P, Q, R, Fig. 7, may be provided for adjusting the positions of the weights on the rod f. A propeller having two intergeared blades is shown in Fig. 8; and Fig. 9 shows two blades connected by one or more flexible members T to balance one another centrifugally.

Filed: 1923-03-13
Abstract: 197,300. Cremer, H. J. de. May 6, 1922, [Convention date]. Locks, permutation; hasp locks.- The sliding bolt of a permutation lock is blocked by notched sliders, some of which allow passage of the bolt in one of their extreme positions, the rest in the other. The bolt comprises a shank 23 with side flanges 24 having staggered notches 25. The flanges 24 fit into grooves 19 of a pair of blocks 18, the shank 23 sliding between the edges of the blocks at one side, and a filler block 21, of depth greater than the depth of the shank, is riveted between the other two edges. Sliders of the form shown in Figs. 10 and 11 are fitted into the transverse grooves 20 of the blocks 18 and pass through the notches 25 of the bolt flanges 24. The sliders 27 have a notch 29 some distance from the shoulder 30, and others 28 have a notch 31 next to the shoulder 32. Fig. 1 shows the lock applied to a hasp 14 hinged to a plate 13 and engaging over a staple 16. To operate the bolt by means of its finger piece 36, the notches 29, 31 in the sliders must be brought into alignment with the flanges 24 of the bolt. To effect this, the sliders 27 must be left in their extreme inward position and the sliders 28 pulled outwards to their extreme outward position as shown in Figs. 8 and 7, respectively. The shoulders 30, 32 prevent the sliders from being pulled out bodily. The sliders may be interchanged to change the combination. The device may be secured to a door and-engage a staple as an ordinary sliding bolt.

Filed: 1949-03-17
Abstract: 661,233. Making dynamo-electric machines. LUCAS, Ltd., J. March 8, 1950 [March 17, 1949], No. 7301/49. Classes 83 (ii) and 83 (iv). Shearing.-A machine for engaging the free ends of windings on an armature with slots in the segments of a commutator comprises the combination of a rotary holder adapted to receive the commutator, indexing means for imparting intermittent angular movement to the commutator and armature, and a recip. rocatory tool adapted to sever the waste ends of the windings and to insert the free ends successively into the slots in the commutator segments. A hollow vertical spindle c provided with a socket d for receiving the commutator is supported by a bearing b in a headstock a. Within the spindle c is provided a resilient collet g having opposed conical outer surfaces g<SP>1</SP>, g<SP>2</SP>, which engage complementary surfaces in a disc j and a sleeve k respectively, the latter being slidable in the spindle c. The collet g is caused to grip the armature spindle by the upward movement of a spring-loaded pneumatic piston n which, through a rod p and abutment piece q, operates the sleeve k. The upper end of the socket d has a flange r having longitudinal slots s corresponding in number to the free ends e<SP>1</SP> of the winding, the lower end of the slots serving as cutting edges for cooperating with the blade t<SP>1</SP> of a horizontally reciprocating tool t. The commutator is located in the socket d by means of a pawl u. The spindle c is intermittently rotated by a pawl-and-ratchet device v, w. In operation, the spindle c is intermittently rotated to index the slots s with the tool blade t<SP>1</SP>. The operator then places the ends e<SP>1</SP> in the slots s and the tool t cuts off the waste from each end and pushes the remaining end into the commutator slot. The spindle c and tool t may be operated from a common driving-shaft y connected to a spindle 6, one end of which carries a crank mechanism for the spring-loaded pawl w. At the other end of the spindle 6 a crank 9 and a link 10 connected to a slidable cam-piece 11 actuates the reciprocatory tool t. The clutch 2 is controlled by a pivoted arm 15 which has a peg 16 engaging a cam groove 17 in a slidable member 18 of the clutch. A spring 19 holds the arm 15 against a stop 21 in the clutch-disengaged position and the arm 15 is operated manually by a lever arm 22. Movement of the arm 15 to engage the clutch also disengages a detent 25 on the arm from a peripheral recess 26 in a disc 27 on the spindle 6. After a complete revolution of the spindle 6 the detent 25 re-engages the recess 26 and the arm returns to its initial position and disengages the clutch. A spring-loaded detent 28 engages recesses 29 in a ring 30 around the spindle c to hold the spindle c stationary between the intermittent rotational movements.

Abstract: 871,834. Ionization chambers; detecting neutrons. RAJEWSKY, B. March 19, 1958 [March 6, 1957], No. 7539/58. Classes 39(1) and 39(4). An ionization chamber comprises two high-tension electrodes 20 and 30 with an interposed measuring electrode 10 and grid 40. The zone formed by electrodes 10 and 20 has wall coatings such that ions are produced by only one kind of radiation, e.g. gamma rays. The zone formed by electrodes 10 and 30 has wall coatings such that ions are produced by two kinds of radiation, e.g. gamma rays and neutrons. Both zones are filled with a suitable gas. If the chamber is placed in a mixed radiation field, the potention applied to the grid 40 can be so adjusted that the ionization current due to gamma rays in the inner zone 10, 30 is balanced by that due to gamma rays in the outer zone 10, 20 so that only the ionization due to neutrons is measured. Different voltages may be connected to individual wires of the grid 40 so that different parts of the outer zone 10, 20 are excited to a different degree. In the arrangement shown the electrodes are concentric hollow spheres. The apparatus may be used in measurements involving variation in the pressure of the gas filling of the chamber when subjected to constant radiation. The grid 40 then enables the ionization current to be adjusted to desired value.
