Title: Improvements in or relating to measuring instruments and balances
IPC: G01G23/375
Filed: 1953-10-05
Abstract: 749,092. Photo-electric weighing apparatus. SCHENCK MASCHINENFABRIK DARMSTADT GES., C. Oct. 5, 1953 [Nov. 29, 1952], No. 27319/53. Class 40 (3). [Also in Groups XVIII and XIX] The deflection of the pendulum of a measuring instrument, e.g. a weighing machine, is transmitted electrically in the form of a proportionate number of pulses which are fed to electronic counting apparatus associated with a printing mechanism. As shown, the pendulum 3 (Fig. 1) of a weighing machine, carrying a visual scale 10, carries a magnetic tape 11 which has a number of equispaced marks superposed thereon. When the pointer 3 reaches its rest position a motor 14 is started by manual or automatic operation of a switch 15 to drive an arm 7 carrying sound heads 8 and 9 to follow the tape 11, whereupon a series of pulses is transmitted by the head 8 to known electronic counting circuits 17 to set a weight-printing mechanism 20. At the zero position on tape 11 a switching-off pulse is received via head 9 which stops the motor 14, and the counting circuits 17, and returns arm 7 to its starting position. To obtain a larger number of pulses for greater accuracy the tape 11 and associated head 8 may be duplicated. In a photo-electric embodiment the tape is replaced by a band 36 (Fig. 3) with a series of marks which produce corresponding pulses in a photo-cell 38 as the pendulum 37 is deflected, an automatic switch 39 directing the pulses to plus or minus counting mechanisms 40, 41 in accordance with the direction of movement of the pendulum, the weight-printing mechanism Z indicating the algebraic sum of the counters. The deflection is also indicated directly by projecting an image of a scale 31 on a screen 34 by a lens 32 and mirror 33.

Abstract: 682,873. Television. RADIO-INDUSTRIE. Oct. 25, 1949 [Oct. 26, 1948], No. 27391/49. Class 40 (iii). The frame or line synchronizing signal for a television transmission system comprises two pulses, one of which is transmitted by amplitude modulation and the other by frequency modulation of the carrier wave. Fig. 2 shows a television waveform in which the frame synchronizing signal comprises a pulse 3 transmitted by amplitude modulation, and a pulse 4 transmitted by frequency modulation spaced from one another by an interval equal to the line scanning period d and positioned so that they do not coincide with the line synchronizing pulses 1. For double interlaced transmission the pulses 3, 4 are arranged to occur during the first half of the interval d and the pulses 3<1>, 4<1> (for the interlaced frame) during the second half of this interval. A television transmission of this kind may be received by receivers arranged to operate with synchronizing signals transmitted by either amplitude or frequency modulation. Frame synchronizing signals of the former type may be separated from linesynchronizing signals by means of integrating circuits or differentiating circuits, Figs. 3 and 4, respectively (not shown), and synchronizing signals of the latter type by arrangements such as disclosed in Specifications 621,484 and 682,847.

Title: Improvements in and relating to apparatus for treating articles by spraying
IPC: A47L15/24
Filed: 1932-10-04
Abstract: <PICT:0408311/IV/1> <PICT:0408311/IV/2> <PICT:0408311/IV/3> <PICT:0408311/IV/4> A machine for treating articles by spraying comprises a casing through which the articles are conveyed between or past spray means consisting of spray pads or boxes which form part of the wall of the casing, the pads being provided with covers removable from the exterior of the casing.  The machine may be used in the treatment of articles such as cutlery, bottles, machine parts, or fabrics.  In the construction shown in Figs. 1 and 2, adapted for washing cutlery, crockery, and like articles, a tunnel-shaped casing 10 is provided at the sides with spray pads 13, between which the articles are intermittently advanced by means of an endless conveyer 15.  The conveyer is mounted on sprockets 16, 17, the shaft 20 of the sprockets 16 being provided with ratchet wheels 21, 22, adapted to be engaged by pawls 23, 24, respectively.  The pawls are connected by bell crank levers to the door 14 of the casing 10, the arrangement being such that the conveyer is advanced a step each time the door is opened or closed.  The door is connected through a rod 35 to a valve lever 34 so that when the door is opened the pressure of liquid supplied to the spray pads is reduced.  The pads are concave, as shown in Fig. 2, and are provided with flanges adapted to be bolted or p  welded to the walls of the casing.  Covers 40 applied to the flanges are detachably connected to pipe lines 41, 42, which deliver washing and rinsing liquids to the pads.  The inner wall of each pad is formed with apertures to receive screwed nozzles 43, Fig. 11, each of which has a flange 45 adapted to flatten the issuing jet.  In a modification, a sheet metal plate is detachably secured to the perforated wall of the pad, the plate being provided with tongues punched up in positions corresponding to the apertures in the pad. In a modification of the machine, the endless conveyer is driven by the motor which drives the pumps supplying liquid to the spray pads. The drive is through a clutch controlled by a foot pedal.  In addition to spray pads at the sides of the casing spray pipes are provided above and below the path of the articles.  In a further modification, the spray means for the cleansing and rinsing liquids are located in the same zone, and the lower part of the casing is divided into a pair of tanks adapted to collect, respectively, the washing and rinsing liquids draining from the articles being treated. A pivoted plate is provided to direct the liquid to either tank, the plate being connected to a rod controlling cocks in the pipe lines so that when the rod is operated to provide, for example, a washing spray, the plate is tilted to direct the liquid to the proper tank.

Title: Doppler radar system
IPC: G01S13/58
Filed: 1964-07-03
Abstract: 1,066,077. Doppler pulse radar. COMPAGNIE FRANCAISE THOMSONHOUSTON-HOTCHKISS BRANDT. July 3, 1964 [July 5, 1963], No. 27597/64. Heading H4D. The invention relates to a Doppler radar system wherein a signal is produced having a frequency bearing a constant relationship to the target radial velocity irrespective of variations in the transmission frequency. In the arrangement of Fig. 1 master oscillator 27 synchronizes oscillators 1, 4 and 8. The output of oscillator I at frequency f 1  is frequency multiplied by a factor m in means 2 which is ganged to similar multiplying means 5 and 7, all under the control of factor m selecting means 26. The resulting signal is pulse modulated in means 17 and transmitted by antenna 19 via T/R box 20. Oscillator 4 operates at a frequency f 2  and oscillator 6 fd operates at a variable frequency (f 2  + -) m centred on frequency f 2 . Oscillator 8 operates at a reference frequency f 3 . The output of oscillator 4 is frequency multiplied by factor m and then subtractively mixed with the reference frequency f 3  in mixer 9 to produce a signal of frequency (mf 2  - f 3 ), which is then further subtractively mixed with the frequency multiplied output of oscillator 6 in mixer 10 to produce a signal of frequency f 3  +fd. This signal is then mixed with the transmission signal in mixer 22 to produce a final signal of frequency mf 1 +f 3 +fd. The echo signal passed by the T/R box 20 is at a frequency mf 1 +fd, where fd is the Doppler shift, and is mixed in mixer 21 with said final signal to produce a signal whose frequency is f 3 , if the term fd in the frequency of oscillator 6 is equal to the Doppler shift. Deviation from this equality is detected and removed by comparing the frequency of the output of mixer 21 with the reference frequency f 3  in 24 and using any detected difference to produce a signal appropriately adjusting the frequency of oscillator 6. The outputs of oscillators 4 and 6 are subtractively mixed in mixer 14 after frequency multiplication by a factor m<SP>1</SP> to produce a signal at a frequency m<SP>1</SP> -fd, which is directly proportional to the m  target velocity and independent of the transmitted frequency mf 1 , and is highly sensitive to velocity changes due to the factor m<SP>1</SP>. In a second arrangement, Fig. 2 (not shown), the oscillator 1, operating at frequency f 1 , is eliminated and the transmission frequency is a multiple of f 2 .

Title: Improvements relating to automobile doors and door latches
IPC: E05B65/32
Filed: 1959-08-13
Abstract: 861,787. Vehicle doors. GENERAL MOTORS CORPORATION. Aug. 13, 1959 [Aug. 13, 1958], No. 27695/59. Class 103(2). [Also in Group XXV] In an automobile door with a vertically extending glass run channel, and having a latch, the latch bolt, a detent therefor and outside operator means for the latch, all lie outboard of the glass run channel in the door, and the latch comprises a latch frame 40 mounted on the joint face of the door, a latch bolt 48 (not shown) and a ratchet wheel 49 mounted on opposite sides of this frame, and a detent 50, which is pivotally mounted on the frame and which has afoot able to abut one of the ratchet teeth to prevent pivotal movement of the latch bolt in a door open-. ing direction, the latch having inside operator means comprising a rod 90 journalled to the frame and crossing inboard of the glass run channel, and a link 92 outboard of the glass run channel connected to the detent 50. As shown outside operator means comprise a lever 58 operable by a push button 30 and pivoted to the frame and to an intermittent link 64 which shifts the detent when in an unlocked position but merely idles in a locked position. A shoulder 68 on the intermittent link co-operates, when in the unlocked position, with a tab 70 on the detent 50, the latter rotating about a pin 52 to free the ratchet 49 and so allow the door to be opened. In a similar manner the door may be opened from inside by a handle which when depressed operates a connecting link 92 through a rod 90 and a remote rod 36, so that the detent is rotated as before. Locking is accomplished by moving the intermittent link 64 sideways so that its shoulder 68 no longer co-operates with the tab 70. This is effected by rotation of a multiarmed lever 82 about its pivot 84, 86, a tab 86 on the lever being connected with a slot 86 in the intermittent link. From the outside the multi-armed lever 82 is rotated through a link 80 which is lifted when the locking lever is rotated about a stub shaft 60 by a key being turned in cylinder mechanism 78, while from the inside the multi-armed lever 82 is rotated directly by a rod 98, this rod being held in either locked or unlocked position by a snapcover spring 102. The latch incorporates "automatic dogging" "remote undogging" and "keyless locking".

Title: Storage address translation
IPC: G06F12/10
Filed: 1972-06-14
Abstract: 1398182 Virtual memory INTERNATIONAL BUSINESS MACHINES CORP 14 June 1972 [13 July 1971] 27707/72 Heading G4A A data processing system of the kind having a virtual memory system includes a main address translating arrangement capable of translating any appropriate virtual address, a special address translating arrangement capable of translating only a selection of virtual addresses, the special arrangement including an associative store storing a translation table, a buffer store arranged to store real addresses supplied by the translation arrangements, and a real address modifier to modify a real address stored in the buffer. The arrangement is used in a byte processor in which successive portions (bytes) of an operand or operands are processed. A virtual address specifying the first portion of an operand is applied to an associative store AA containing, e.g. eight recently used virtual addresses. If a match is obtained a corresponding real address is read into buffer SALS and used to address the main store MS via register SAR. Circuit MOD 1 then modifies (increments) the buffered real address to obtain successive bytes of the operand from store MS. Where two operands are involved both their real addresses OP1 and OP2 are buffered, the addresses being incremented alternately. The real instruction address IAR may also be buffered. A store LAS contains the virtual addresses corresponding to the buffered real addresses. MOD1 is arranged to produce an overflow c when the incrementing of the real addresses causes a page boundary to be crossed. Generally successive virtual addresses relate to successive pages and in response to signal c MOD2 increments the virtual address and applies the result to associative store AA. If a match occurs the corresponding real address is read out and the procedure above repeated. The crossing of a page boundary requires a further translation since the new page may not be resident in main memory or if so resident may not be physically adjacent the old page so that merely incrementing the real address would produce an error. A conventional arrangement involving table lock-up is described for use when no match is obtained in the associative store AA.
