Title: First person photography or other optical recording
IPC: G03B15/00
Filed: 1975-02-14
Abstract: 1456792 Systems incorporating cameras; studios V J GRAETER 14 Feb 1975 6426/75 Headings G2A and G2X [Also in Divisions H3-5] An optical image of an action S substantially as viewed from the eyes, or from closely adjacent the eyes, of a performer 4 involved in the action is recorded, e.g. by a still, movie or television camera 34, 35 or 32 or a light meter 33, by reflecting an image of the action by a first mirror 8 located directly in the line of sight 7, or directly adjacent the line of sight, of the performer in a different optical direction to second mirrors 30, 31, 28 and 29 which reflects the image to the recorders, and maintaining the spatial arrangement of the recorders relative to the mirrors while co-ordinating their movement substantially simultaneously with movement of the line of sight of the performer to maintain reflection to the recorder of the image viewed by the performer. A colour temperature meter 36 may also record the image via a mirror similar to said second mirrors but as shown it receives the image direct from the mirror 8. The mirrors form part of an optical unit 1 mounted on a cantilevered boom 2 for pivotal movement about an axis 3 substantially corresponding to the axis of rotation in the vertical plane of the head of the performer 4, the boom being movable by a hydraulic piston and cylinder unit 5, or by a motor driven chain drive and crank unit, Fig. 7 (not shown). The arms of the performer rest upon supports 6 which may . be inter-connected by an adjustable and removable bridge (24), Figs. 2, 3 and 4 (not shown), whereby the performers arms will move at a controlled speed with the unit 1 when this is itself moved by another person, e.g. a film director. The mirror 8 is angularly adjustable to suit different performers and if disposed directly in the line of sight 7 it is a one-way or transparent mirror so that the performers vision is not interrupted, and a split shield may be provided to prevent images from behind the mirror being transmitted to the recorders, the shield comprising an upper portion directly adjacent the mirror and a lower portion spaced a short distance from the mirror, a space for the line of sight being provided . The unit 1 and the operator are supported on a frame 13 which can be rotated about an anchor foot 11 while being supported on wheels 14, and the foot 11 may be raised to allow movement of the frame to any position on the floor. The seat 18 may be moved horizontally on the frame 13. A monitor 19 for the operator and a monitor 20 may be provided, and the operator may control the movements of the apparatus. The optical unit 1 may be supported on a beam cantilevered from and mounted for universal movement on a tripod, Fig. 9 (not shown). A battery of lights (39) which are preferably shatter-proof and explosion proof may illuminate the action area S, e.g. an operation on a patient, and they may have heat absorption lenses. Alternatively, the unit 1 may be mounted on an overhead support, Fig. 10 (not shown), or on a boom on a tracked vehicle, Fig. 11 (not shown).

Abstract: 440,920. Vacuum - cleaner nozzles. REPLOGLE, D. B., 940, Arlington Avenue, Berkeley, California, U.S.A. March 1, 1935, No. 6535. [Class 8 (i)] A floor tool for a suction cleaner comprises an application head constituted by an outer shell member and an inner shell member spaced apart at or adjacent their ends to form pockets which accommodate yieldable supports carrying rollers. The outer shell 2 has a shank 3 connected by a joint 5 with a stub portion 31 which is connected to the suction pipe by a spring finger 32 ; the inner shell member 8 fits tightly within the outer shell or may be positively secured therein, and is cut away at 8<1> to permit the passage of air to the suction pipe. The shells define at their ends pockets 9 which accommodate spring shanks 10 carrying rubber covered rollers 12. The inner and outer shells also define pockets 16, 161 which due to the resiliency of the walls accommodate strokers 17, 17<1>, the rear one being cut away at its central upper part to permit the passage of air to the suction pipe ; the strokers are of material such as raw hide or hard fibre, and their lips 18, 18<1> are inwardly turned; this permits rocking of the tool, and the particles of dust roll up the rear stroker ; the front stroker may be replaced by a brush. The open spaces 23 at the ends of the application head are normally closed by plates 25 carried by the roller shanks 10, but when pressure is exerted to press the tool on to the floor against the pressure of the spring shanks 10, the spaces 23 are partly uncovered to permit the entry of a thin sheet of air.

Abstract: 471,681. Knitting-machines. MELLOR, BROMLEY, & CO., Ltd., BROMLEY, T. C., and SHORTLAND, A. March 5, 1936, No. 6697. [Class 74 (ii)] Needles, jacks, sinkers, &c. mounted for pivotal movement in their bed are selected by a pattern wheel having one or more rows of teeth and maintained constantly in active position with respect to the stems of the needles or like. As applied to a rotary cylinder machine, the pattern wheel, which may have two rows of teeth constituted by bits 9, is driven either by meshing with the jacks 21 or needles or by gearing 31, 32 from the needle cylinder. Alternatively, the teeth may be provided by the projecting portions of notch discs or plates. In the form shown, Fig. 4, the pattern bits 9 are movable by hand radially from operative to inoperative position. The teeth in one row may be displaced angularly from those in the other or another row so that the teeth of one row co-operate with one set of spaced needles while the other row co-operate with intervening needles. The jacks 21 may have heads 21a having V-shaped formations thereon engaging notches in the butts of the corresponding needles. The invention is applicable to multi-feeder machines and to cylinder- and-dial machines. In a straight-bar machine, the pattern wheel may be mounted upon the cam box so that the teeth can act upon the needles or jacks before the stitch cam. For reverse action, a switch-over cam may be provided, or two pattern wheels, one on each side of the cam box, may be fitted.

Title: Improvements in or relating to apparatus for producing electric waveforms for use inadjustable delay- or time-measuring systems
IPC: G01S1/24
Filed: 1948-03-04
Abstract: 654,979. Changing frequency and waveshape. SPERRY CORPORATION. March 4, 1948, No. 6779. Convention date, March 4, 1947. [Class 38 (ii)] [Also in Group XL (c)] An adjustable delay or time measuring system of particular use in radar or pulse hyperbolic navigation systems (e.g. Loran) includes a plurality of sources of sinusoidal electric waves the frequencies of which are multiples one of another, a corresponding plurality of adjustable phase shifters connected one to each source and so ganged together that the ratio of the phase shifts produced by each to that produced by another is equal to the ratio of the frequencies of the sine waves treated. The phase shifted waves are superimposed in a common output circuit to produce a composite waveform periodic at the lowest frequency but which has a peak constituted by a peak of the highest frequency superimposed upon the peak of every component of lower frequency. The output of an oscillator 1 may be applied to a frequency dividing chain 2, 3, 4, to produce a series of waveforms whose frequencies are multiples one of another. A reference waveform of the lowest frequency may be derived at 18 and the output of each divider is fed to one of phase shifters 5, 6, 7. These are ganged together as indicated at 8, 9, 10, 11, the gear ratios being equal to the frequency ratios of the waveforms. The outputs of the phase shifters are added in series to produce a waveform such as shown at 22 of Fig. 2, in which 181, 20 and 21 are respectively the reference waveform and the waveforms from phase shifters 7 and 6. Waveform 22 has a peak 23 which may be adjusted over a full cycle of wave 181 and which may be selected by clipping circuit 12 ; its position is indicated by counter 13 coupled to control 16. Synchronization of the wave 18<SP>1</SP> with one of a pair of Loran signals and adjustment of the clipped peak of the waveform 23 to coincidence with the other on a cathode-ray tube display in order to determine the interval between them is described with reference to Fig. 3 (not shown). It is stated that the phase shifters 5, 6 and 7 may comprise a phase-splitting network and a phase-shifting transformer, one embodiment being described with reference to Fig. 4 (not shown).

Patent GB-551615-A (GB)
Title: Method of widening fabrics on flat knitting machines
IPC: D04B11/28
Filed: 1941-05-30
Abstract: 551,615. Knitting. NATIONAL SILK HOSIERY MILLS, Inc. May 30, 1941, No. 6949. Convention date, July 9, 1940. [Class 74 (ii)] Widening is effected on a straight-bar machine by laying yarn, while the needles are raised, on the beard side of an outer needle 1 added to the previous marginal needle 0 and to such an extent outwards beyond such added needle that after the yarn 21 has been carried down by the added needle and the needles are again raised with the yarn still in front of the added needle, the yarn without passing around the back of the added needle loops about the sinker c between the added needle and the next inward needle to form a loop 31 penetrated by the added needle at the next course. Two or more needles may be introduced at each step at each selvedge, the yarn being looped at each stage around the sinker between the outermost added needle and the next inward needle to form a loop which is subsequently an additional selvedge loop in the next course. The method, which may be used in the knitting of the heel or other part of a full-fashioned stocking, is applicable to machines having a number of alternately operative feeding devices for knitting ringless work. The loop 31 when it falls from the sinker c may take either of the forms shown in Figs. 9c, 10c or 11c, dependent upon the amount of twist in the yarn, each of which forms of loop is penetrated by the rising needle 1 and is knitted. Accidental non-penetration of the loop results in the formation of a loop such as 32, Fig. 15g, by the needle next inward of the added needle.

Title: Driver for lathes
IPC: B23B31/12
Filed: 1951-03-28
Abstract: 678,653. Chucks. FISCHER AKT.-GES., G. March 28, 1951 [April 1, 1950], No. 7204/51. Class 83 (iii). A lathe driver comprises at least two clamping jaws 25 which are pivotally mounted on a floating ring 11 and engage pins 15 on a ring 8 keyed to the conical end of the machine spindle 1, the clamping jaws being brought into engagement with the work by rotating the floating ring in the opposite direction to the driver's rotation; at least two further jaws 27 are also pivoted on the floating ring and are brought into engagement with the work by rotating an outer retaining ring 16, which has pins 21 engaging the jaws 27, and clamping it in position. When the machine spindle is braked, the inertia of the work causes the jaws 27 to grip more firmly so that the work is still gripped if the clamping jaws 25 are lifted under centrifugal force and the inertia of the work. The floating ring 11 is supported on three leaf-springs 22 and is prevented from moving axially by guide-plates 12 engaging a peripheral groove 14 in the ring. The clamping surfaces of the jaws are in the shape of logarithmic spirals and are knurled or serrated. To grip work between the driver and the tailstock, a clamping-screw 19 engaging a groove 9 on the ring 8 is released and an outer casing 29 secured by screws 31 and a reinforcing ring 30 to the pivot pins 24 is rotated in the direction opposite to the direction of rotation. The jaws 25 are thus rotated about the pins 15 until they engage the work, two projections 32 on the floating ring engaging lugs 17 on the outer retaining ring 16 and carrying the latter round with them. The outer ring 16 is then rotated further in the direction opposite to the direction of rotation, causing the other jaws 27 to pivot about the pins 23 until they engage the work, and the ring 16 is clamped in position by the screw 19. To prevent the floating ring 11 from being rotated too far with respect to the fixed ring 8, so that the pins 15 would be able to come out of the slots 26 in the jaws, a pin 35 on the ring can engage with two stop pins on the fixed ring 8.
