Title: Apparatus for use in determining the ultimate tensile strength of steel under impact conditions
IPC: G01N3/303
Filed: 1948-12-15
Abstract: 656,117. Testing physical qualities. VIVIAN, A. C. Dec. 15, 1948, No. 32461. [Class 106 (ii)] The ultimate tensile strength of a steel test bar 18 is measured by allowing a weight or tup 22 to fall a predetermined distance on to an anvil 21 suspended from the test bar, to stretch and fracture the test bar. The falling weight and anvil member are allowed to fall into an air cylinder 23, after fracture of the test bar, to arrest the movement of the weight and record, on a chart 25 by means of a pen 24 carried on the weight 22, the penetration into the air cylinder as a measure of the residual energy of the weight. Then if W=weight of falling tup, Wa =weight of anvil assembly, H=initial height of the falling tup above the anvil, Mc=movement of tup and anvil assembly from initial position of anvil to top of cylinder, Hy=plunge of tup and anvil assembly into cylinder ; then the total energy of the system=WH+(W+Wa) (Hc+Hy) and if the residual energy is denoted by R, the losses by L and the energy used to stretch and break the test bar by Q, then Q=WH+(W+Wa)(Hc+Hy)-R-L. A differential hand winch 37 is provided for raising the weight 22 which is held in position and released by a catch plate 27 and trip mechanism 31 provided with a handle 35. A spring 36 urges the catch plate away from the weight when the mechanism is tripped faster than the weight would more it, thus leaving the weight to fall freely within the guide plates 26.

Abstract: 1,011,248. Moulding hollow articles. OLIN MATHIESON CHEMICAL CORPORATION. Aug. 23, 1962 [Sept. 1, 1961; Feb. 7, 1962], No. 32489/62. Heading B5A. [Also in Division F3] Hollow articles of a crystalline olefinic polymer, such as linear high density polyethylene or propylene, are compression moulded at a temperature below the crystalline melt temperature of the material, the articles thus formed having tensile strengths up to ten times that of the undeformed polymer. A cartridge case 1 such as in Fig. 3 having a thick lower portion 8 and a thin tapered wall 9 is compression moulded from blank 7 in the die cavity 28 (Fig. 1) by the tapered portion 13 of the punch 12. Punch speeds of about 5-60 feet per minute are used to preform the moulding, the stroke being guided by the co-operation of projection 15 with the channel 23 in the supporting block 11. In the embodiment shown in Fig. 4 the mould is heated by a circulating medium system 73 and the article is removed from the die by a further downward movement of the punch 53 after the bottom 80, pivoted about 81, has been released by a suitable rotation of the locking nut 79. A blank having a metal casing may be used, the casing acting as a liner to the mould and being retained upon the finished cartridge. Collapsible dispensing tubes and containers may also be formed. An alternative set of blanks and compression moulding apparatus for forming cartridge cases can be seen in Figs. 11-14 (not shown). The mould may be lubricated by a suitable substance such as ethylene glycol.

Title: Method and apparatus for deriving a transform of an electrical signal
IPC: G06F17/14
Filed: 1973-05-03
Abstract: 1372137 Computing signal transforms MULLARD Ltd 3 May 1973 [12 July 1972] 32573/72 Heading G4A The transform S<SP>1</SP> of an electrical signal S is computed using a matrix M= (M jk ), the rows of which are derived from a maximal length pseudo random binary code input (PRBS) of length m by cyclic rotation. The zero values in each code are replaced by - 1, each row of the matrix summing h - 1 and when correlated with itself producing a first known constant value, m, and when correlated with any other of the sets producing a second known constant value, - 1. The relationship between the transformed signal S<SP>1</SP> [A j ] and the input signal S is S<SP>1</SP> =M<SP>-1</SP>S and it can be shown that where E is a matrix of the same dimension as the matrix M having all its coefficients equal to 1. Consequently the coefficients S<SP>1</SP> j  of the transformed signal S<SP>1</SP> are given by where S k  are the values of the input signal. Apparatus for deriving these coefficients using this equation comprises a PCM coder 2 (Fig. 4) for converting the signal if it is in analogue form to serial digital form and circulating stores 3, 4 alternatively storing sets of seven digital samples (each of 8 bits), the sets of reference signals each being of 7 bits. The outputs of the stores are connected to an adder 7 and to a multiplier 8. Adder 7 forms in a circulating store 9 the sum #S k . Multiplier 8 operates only on the sign bit of the digital samples, passing the sign bit unchanged if the associated bit from PRBS generator is "1" and inverting it if it is "0". Consequently adder 12 forms the sum in a recirculating store 13 of the digital signals S k  multiplied by the associated bits of the first reference sequence M 1k . Stores 9 and 13 are connected to adder 13 which provides the output signal which is shifted by 3 bits (to provide division by m + 1 = 8) to derive the first coefficient A 1 . The process is repeated to derive the remaining coefficients A 2  ... A 7 , the PRBS reference signal being shifted by one bit between each calculation. The PRBS generator may comprise a 7-stage shift register stepped between calculations with an output from each stage or a read only store read out at the required rate by a multiplexer. The circuitry preferably comprises integrated field effect transistors. The PRBS signals may be replaced by Barker codes.

IPC: A47L11/16
Filed: 1952-12-23
Abstract: 740,250. Floor polishing machines. BYLOCK ELECTRIC, Ltd. Dec. 23, 1953 [Dec. 23, 1952], No. 32658/52. Class 138(1) In a floor polishing machine of the type comprising a plurality of disc brushes and driving wheels therefor driven frictionally from a vertical motor-driven shaft, two brush driving wheels at least are sumpported by bearings which are slidably mounted in rectilinear guides by which they are guided towards and away from the motor-driven shaft, the movement of the wheels being controlled by means operative from the handle of the machine. The machine comprises a base plate 3, Figs. 2 and 5, surmounted by a similarly shaped casing 4, Fig. 1, which in turn is surmounted by the casing 19 for an electric motor 5. A manipulating handle 18 is connected to the casing 19 in known maner by a fork 17, one limb of which has an extension finger 15 passing through a slot 16 in the casing 4. A striker roller 21 is also mounted on the same limb for coasting with a switch 20 for controlling the motor 5 and a headlamp 22. The vertical shaft (not shown) of the motor 5 is disposed centrally between the two lower brush driving wheels 2, Fig. 2, which wheels have tyres 6 adapted to engage the tyre 6 of the upper brush driving wheel 2, Fig. 2. Referring to Fig. 5, each wheel 2 adapted to engage the motor shaft is mounted on a spindle 8 mounted in a bearing 9'carried in a plate 10, and is adapted to resiliently and releasably carry at its lower end a brush 1. A square block portion 10a of the plate 10 is slidable against the urge of a spring 10c in a slot 10b in the base plate 3. The plate 10 is retained on the plate 3 by a bottom plate 10d. As shown in Fig. 2, each plate 10 has a bevelled corner adapted to engage a roller 13 mounted on a cam plate 12 pivoted to the plate 3 at 11. An arm 14 on the cam 12 is engageable by the finger 15 on the fork 17. When the handle 18 is moved to a vertical position the motor is first switched off and the finger then engages the arm 14 to pivot the arm 12 to cause outward movement of the wheels 2 against their springs and disengage the wheels from the driving shaft. When the handle is moved towards its operative inclined position, the finger is first released from the arm 14 to allow the springs 10c to move the wheels into engagement with the driving shaft and the motor is then switched on. The upper wheel 2, Fig. 2 is similarly slidably mounted under the urge of a spring but its mounting plate 10e is not acted upon bythe cam. Stop means 12a limit the movement of the cam. The brush body 1a is engaged by three spring arms 24a of a spider 24 on the spindle 8. A bar 26 on the end of the spindle passes through a diametral slot in the body 1a and engages abutments (not shown) in a recess 27 of the the body to effect a positive drive. In a modification, Figs. 6 and 7 (not shown), the spider is dispensed with and the bar 26 replaces a spring strip whose ends are formed with bent-up wings to engage the underside of the brush body.
