Title: Improvements in or relating to conveyor belts
Inventor: THORNLEY ERNEST RAYNER
IPC: B65G15/38
Filed: 1955-12-19
Abstract: 797,749. Laminates. CABLE BELT, Ltd. March 14, 1957 [Dec. 19, 1955], No. 36360/55. Drawings to Specification. Class 140. [Also in Group XXX] A conveyer belt for an endless belt conveyer of the kind in which the belt is supported on a pair of endless driving cables consists of a core of flexible substantially flameproof elastomeric material compounded to give a low mechanical strength in which a series of spaced cross straps in the form of metal rods are embedded, and an outer envelope formed in one or more layers of elastomeric material which is both substantially flameproof and compounded to give high mechanical strength, the core and envelope being bonded together to form a unitary belt structure. Cable-engaging means in the form of extruded grooved strips are provided near the edges of the belt so as to lie adjacent the ends of the cross straps. A reinforcing layer of textile fabric may be included between the outer envelope and the core, this being coated with a composition similar to that used for the envelope, but where an inherently flameproof elastomer, e.g. Neoprene or polyvinyl chloride, is used for the envelope the coating for the reinforcing layer may include some natural rubber. In a typical example given, Neoprene is used for the envelope together with small quantities of flameproofing agents and a high proportion of high abrasion furnace black, a similar composition but with a small proportion of natural rubber is used for an inner layer and the cable-engaging strips, a composition of generally similar form but with a larger proportion of rubber and using semi-reinforcing furnace black in place of the high abrasion furnace black is used for the fabric reinforcement layer, and a composition consisting mainly of natural rubber, whiting and china clay, with chlorinated paraffin and zinc borate as flame-proofing agents is used for the core. Other examples are given using either polyvinyl chloride as an inherently flameproofing elastomer or natural rubber together with large proportions of chlorinated naphthalene in conjunction with antimony trioxide for flameproofing, or combinations of these. Specification 711,524, [Group XXX], is referred to.

Title: Improvements in or relating to computing or indicating apparatus
IPC: G01C22/00
Filed: 1946-12-10
Abstract: 619,565. Counting-apparatus. REILLY, H. L., SCRIMSHAW, F. H., and LAMBERT, P. C. Dec. 10, 1946, No. 36438. [Class 106 (i)] In apparatus in which a constant speed movement is combined with a further applied movement, the constant speed movement is set in by adjustment of a continuously variable gear driven by a constant speed motor the motor also driving a time indicator, and means are provided for driving the time indicator and the continuously variable gear simultaneously at a higher speed than normal in either direction. The invention is described with reference to an aircraft ground position indicator in which a component of wind velocity is set in and combined with air miles. The constant speed motor 21 drives a side wheel 15 of a differential gear via gears 52, 51, 54, 55, 57, 56, 61, 80, 77 and 78 and a variable friction gear comprising a disc 22, ball 23 and cylinder 24. The friction gear is adjusted according to the known value of the north-south wind component by a knob 27 which adjusts the position of the ball 23. The other side wheel 14 of the differential gear is driven by a repeater motor 20 operated by the north-south component of air miles obtained from an air position indicator 16 which is associated with an air mileage unit 17 and a repeating compass 18 to resolve a drive from unit 17 into two drives representing northsouth air miles and east-west air miles. The resultant output from the differential gear operates a counter 11 to show north-south ground miles and a transmitter 12 to operate a stylus &c. A similar arrangement of friction gear &c. is provided for east-west components of wind and air. miles. A sleeve 58, splined on a shaft 59 carries the pinion 61 and can be raised or lowered by operating the knob 73 of a rod 72, thus disengaging pinion 61 from the pinion 56 and causing a bevel-wheel 71 to engage one of the bevel-wheels 62, 63 to produce a highspeed drive in either direction. A spring 67 restores the normal drive. The motor, via pinions 80, 81, 85, 86 also drives the hands 88 of a clock 87. A clutch 83 slips when the hands are adjusted by turning end 84a of shaft 84, and a magnetic clutch 75 is only engaged when the air position indicator 16 is operative. If the apparatus has been in use with the wind components incorrectly set for n hours, the knob 73 is pulled out and reverse drive at high speed is effected until the clock reading is reduced by n hours and then pushed in to effect forward high-speed drive until the clock moves forward n hours plus the time taken for the correcting operation. The knob is then released to restore the normal drive. In a modification, the high-speed drives from the motor are dispensed with and independent means such as a crank handle 102 and toothed wheels 104, 105 provided, a clutch 101 slipping when these are operated. Means may also be provided to disengage the clutch 83 while the knobs 27 and 47 are being reset.

Abstract: 1525857 Input/output control PHILIPS ELECTRONIC & ASSOCIATED INDUSTRIES Ltd 5 Sept 1975 [10 Sept 1974] 36621/75 Heading G4A In a computer system in which a bus control unit BCU (Fig. 1) controls the transfer of information on a bus B between a CPU, main store MS and control units CU1, CU2 associated with peripheral units P1, P2, P3 ..., each I/O instruction is subdivided into a number of separate independent steps by control means in the CPU so that each step may be independently performed by the peripheral control unit, after which an interrupt request is sent to the CPU for the next step. As described an I/O instruction S10 from magnetic core or I.C. main store MS is fed out to register S10R connected to control store CS to cause read out of a micro programme word to controller B10 which results in an instruction step OC1 being fed via register ROC and unit BCOM under the control unit BCU to an adapter HSA1, HSA2 (Fig. 2) associated with the addressed peripheral control unit CU11, CU12.... The address at which the control store is accessed is held in register CR and on completion of the step, when the interrupt request INT is accepted, the register is incremented to cause read out of the next micro programme word. Each I/O instruction (Fig. 3, not shown) includes an operation code, peripheral address and address at which information is to be stored or read at the peripheral. For a disc store this may include a cylinder number, head number and section number. When data is transmitted from the disc to the store MS via bus GB2 (together with its storage address) the address for storage at the main store and held in register RMSA in adapter HSA1 is fed to counter BMT1 for incrementing and the length of the storage area, held in register RMSL, is fed to counter OMT1 for decrementing. In a similar manner data read from the main store is fed via bus GB2 to the adapter HSA1 for storage on the disc of peripheral P111. For a key search procedure the second part of the instruction include., as well as the address and the length information 10A, 10L, a section KA representing the address of the search key, a section KL representing the length of the key, a section RL representing the length of the record and a section DL representing the length of data on record. The portions KA and KL are stored in registers RMSKA, RMSKL and using the portion KA the main store is accessed to derive the first part of the key which is stored in register DR1. At the assigned sector Sn of the disc the first key K is read and stored in register DR2, this process being repeated for successive keys of the section until at comparison the next section of the key is fetched. Figs. 6, 7, 8, 9 (not shown) give more details of the main store MS and switching device, control section of the CPU, adapter HSA1, and peripheral control unit CU11 and peripheral devices P111, P112 respectively.

Title: Anti-skid device for vehicles
Inventor: WILSON ALEXANDER JOHN
IPC: B60T8/36
Filed: 1962-09-27
Abstract: 1,042,772. Preventing skidding. GIRLING Ltd. Sept. 19, 1963 [Sept. 27, 1962], No. 36672/62. Heading F2F. A device for preventing a vehicle from skidcomprises a spindle 25 rotatable and axially movable parallel to the longitudinal axis of the vehicle in a housing 26, worm or skew gears 27 for rotating the spindle 25 at a speed proportional to that of the road wheels, a flywheel 36 rotatable and axially movable on the spindle and coupled thereto by a slipping clutch 37 which, under circumstances mentioned below, acts to limit deceleration of the flywheel in accordance with the deceleration of the vehicle and axially acting springs 39 which normally hold the clutch engaged. When the vehicle is travelling normally the parts are arranged as shown in Fig. 1 where a spigot 32 on the right-hand end of the spindle closes a passage 35 leading to a servo. As speed increases shoes 38 on the springs 39 are centrifuged outwards to engage the inside of the flywheel 36 and the springs 39 retract a sleeve 41 from the left-hand end of the housing 26; the spindle 25 is now free to move to the left but it does not do so because the forces on it are balanced so that the passage 35 is not uncovered. If a road wheel is now rapidly decelerated, the reaction between the worm and worm-wheel at 28 tends to move the spindle to the left, but as long as the vehicle decelerates correspondingly, inertia forces on the spindle and flywheel will prevent the passage 35 from being uncovered. If, due to skid, the vehicle does not decelerate the passage 35 will be uncovered and air will be admitted to a servo which reduces the braking effort applied to the road wheels.

Title: Manufacture of quinoline derivatives
IPC: C07D215/233
Filed: 1930-12-08
Abstract: Quinoline derivatives containing an amino or substituted amino group in the 4-position and in the 2-position an unsaturated residue having at least three carbon atoms not forming part of a ring are prepared by (1) converting the methyl group of 2-methyl-4-aminoquinoline into the unsaturated residue by interaction with an alkyl, alkylene, aralkyl or aralkylene aldehyde, (2) replacing an amino residue for halogen in a 4-halogenquinoline containing an aforementioned unsaturated residue in the 2-position, or (3) by substituting in 2-methyl-4-halogenquinoline in either order of succession the amino residue for halogen and the unsaturated residue for the methyl group. The products possess therapeutic properties. According to the examples, (1) 2-octenyl-4-amino-6-ethoxyquinoline is prepared by condensing 2-methyl-4-chloro-6-ethoxyquinoline with aenanthol in the presence of zinc chloride and treating the resulting 2-octenyl-4-chloro-6-ethoxyquinoline with ammonia; (2) 4-chloro-6-ethoxyquinaldine is condensed first with cinnamic aldehyde and then with ammonia giving 2-d -phenylbutadienyl-4-amino-6-ethoxyquinoline; (3) 2-pentenyl-4-amino-6-ethoxyquinoline is obtained when 4-chloro-6-ethoxyquinaldine is heated with ammonia to form 4-amino-6-ethoxyquinaldine, which is then condensed with butyraldehyde; the same product results when 4-chloro-6-ethoxyquinaldine is condensed first with butyraldehyde and then with ammonia.  The samples filed were prepared by (1) converting 4-chloroquinaldine by treatment with ammonia into 4-aminoquinaldine and condensing the latter with butyraldehyde to give 2-pentenyl-4-aminoquinoline ; (2) reducing 2 : 6-dichloro-4-nitro-1-methylbenzene to the amino compound, which is then transformed into b  - (3 : 5 - dichloro - 4 - methyl - phenylamino) - crotonic acid ester by treatment with acetoacetic ester, condensing the ester by heating to produce 2 : 6-dimethyl-4-hydroxy-5 : 7-dichloroquinoline and treating with phosphorus pentachloride to form 2 : 6-dimethyl-4 : 5 : 7-trichloroquinoline; the latter by heating with ammonia yields 2 : 6 dimethyl-4-amino-5 : 7-dichloroquinoline which, condensed with cinnamic aldehyde, produces 2-d -phenylbutadienyl 4-amino-5 : 7-dichloro-6-methylquinoline ; (3) transforming 2 : 5 : 6 : 8-tetramethyl-4-hydroxyquinoline into the 4-chloro body using phosphorus oxychloride, heating with ammonia to form the 4-amino compound and condensing this with cinnamic aldehyde to produce 2-d -phenylbutadienyl-4-amino-5 : 6 : 8-trimethylquinoline ; (4) condensing 4-amino-6-ethoxyquinaldine with hydrocinnamic aldehyde to obtain 2-d -phenylbutenyl-4-amino-6-ethoxyquinoline ; (5) condensing 2 : 5 : 6 : 8-tetramethyl-4-aminoquinoline with crotonaldehyde, yielding 2-pentadienyl-4-amino-5 : 6 : 8-trimethylquinoline ; (6) heating 2-d -phenylbutadienyl-4-chloro-6-ethoxyquinoline with dimethylamine to form 2 - d  - phenylbutadienyl - 4 - dimethylamino-6-ethoxyquinoline.
