Title: Improvements in and relating to methods of and means for lubricating axle bearings
IPC: B61F17/20
Filed: 1931-12-22
Abstract: 394,661. Lubricating axle-bearings. MATTHEWS, E. F., Elm Cottage, Watford Road, Wembley, Middlesex. Dec. 22, 1931, No. 35467. Convention date, Nov. 25. [Class 12 (iii).] In means for lubricating railway-vehicle axle bearings wherein lubricant is raised from a well by a transfer member rotating with the axle, the transfer member is so constructed that an axial thrust is imparted to the raised lubricant, whereby the latter becomes detached from the transfer member and reaches a collecting member by bridging across an axial interspace between the transfer member and at least the major part of the collecting member. The transfer member is in the form of a ring R extending helically around the axle 1 and secured to a bar 2 which is bent as shown in Fig. 2 and which is secured to the axle end by screws 3. The intermediate part 4 of the bar 2 is of trapezoidal form, as shown in Fig. 3. Axial thrust is imparted to the raised lubricant by reason of the rear helical end face of the ring R and of the inclined side faces 5 of the part 4. On its inner periphery the ring R is formed with two sets of drip points 7, 7<1>, one or other of which functions according to the direction of rotation, and the ends 8, 8<1> of the ring are shaped so as to form thread-producing parts, while the outer periphery and the front end face of the ring are stepped as shown at 9, 10 so as to facilitate the centrifugal throwing- off of lubricant, these various parts being so arranged as to obviate the occurrence of critical speeds. Thus an auxiliary supply of lubricant to the collecting member, independent of that transferred by the axial thrust, is ensured at all times, the collecting member being so shaped that at least its extreme front end is so situated as to be capable of receiving the auxiliary supply.

Abstract: 1,091,384. Seats. FORD MOTOR CO. Ltd. 9, Aug., 1966 [Sept. 21, 1965], No. 35506/66. Heading A4J. Bracket 41, pivot 26 and plate 47 are fixed to the framework of a vehicle and support seat 10 and back rest 12, so that forward folding of the back rest 12, about pivot 26, actuates arms 36 and 50, as a parallelogram linkage, through link 30, to move the seat forwardly and downwardly. Arm 50 is part of a torsion spring 44 anchored at 46 to plate 47 and is slightly shorter than arm 36, which moves through its dead centre with respect to pivots 40 and 52 as the seat is lowered against the action of torsion spring 44. In the lowered position (Fig. 2, not shown), the line of action 38, 52 of the torsion spring lies below pivot 40 and the spring accordingly urges the seat downwardly to abut a stop (not shown). On returning the back rest to the upright position, the back of the seat is raised, by link 30, to bring the line of action 38, 52 above the pivot 40 and allow torsion spring 44 to restore the seat to the position shown.

Title: Computer memory address generator
IPC: G06F9/32
Filed: 1969-07-16
Abstract: 1,270,311. Computer address generator. RCA CORPORATION. 16 July, 1969 [22 July, 1968], No. 35845/69. Heading G4A. The invention relates to an address generator capable of modifying a supplied address to access various locations having addresses near to the supplied address. A programme counter 10 normally incremented by 1 holds an instruction address C<SP>5</SP>-C<SP>0</SP>. An address modification register 12 holds position data P, value data V and a sign bit indicating whether the instruction address is to be modified by addition or subtraction. The position bits are applied to a decoder and determine how many bits of the counter are supplied to a first operand register 20. If P<SP>1</SP>P<SP>0</SP>=00 C‹ is not supplied. If P<SP>1</SP>P<SP>0</SP>=01 then C<SP>1</SP> and C‹ are not supplied. P<SP>1</SP>P<SP>0</SP>=10 inhibits C<SP>2</SP>, C<SP>1</SP>, C‹ and P<SP>1</SP>P<SP>0</SP>= 11 inhibits C<SP>3</SP>, C<SP>2</SP>, C<SP>1</SP>, C‹, appropriate bits being supplied to AND gates 32, 33, 34 as shown in the Figure. The position bits also determine to which positions in a second operand register 22 the value bits V are supplied. If P<SP>1</SP>P<SP>0</SP>=00 register 22 holds 000V<SP>1</SP>V<SP>0</SP>1 If P<SP>1</SP>P<SP>0</SP>=01 register 22 holds 00V<SP>1</SP>V<SP>0</SP>10 If P<SP>1</SP>P<SP>0</SP>=10 register 22 holds 0V<SP>1</SP>V<SP>0</SP>100 If P<SP>1</SP>P<SP>0</SP>=11 and S=+ register 22 holds 0V<SP>1</SP>V<SP>1</SP>000 and 001000 is added to the contents of register 22. If P<SP>1</SP>P<SP>0</SP>=11 and S=- the register 22 holds 000000. The adder adds or subtracts the second operand to or from the first and provides a next address 14. It can be seen that the four values of the position bits and four values of the value bits enable the digits 1-8, 10, 12, 14, 16, 20, 24, 28, 32 and 0 to be added to or subtracted from the supplied address. The invention is applicable to longer address in which case the address modification number will be relatively much smaller than the supplied address, e.g. for a 27-bit address register 12 need only hold 16 bits.
