Abstract: 1,055,340. Belt fastening machines. HAYDEN-NILOS Ltd. Oct. 21, 1965 [Oct. 29, 1964], No. 44079/64. Heading F2Q. U-shaped joining elements 35 are stapled to a belt end 15 by a portable hydraulically operated machine wherein an hydraulic ram 20 moves a member 27 through a slot 41 in a block 31 to drive the pointed limbs of staples 43, located in opposed pairs of grooves 42 in the sides of slot 41, through holes in the limbs of the elements 35 and through the belt end 15 between said limbs to impinge in point bending recesses 38 of an anvil 37, a control lever 57 (Figs. 1-4, not shown) being moved after the staples have been bent over to momentarily open a relief valve 47 in the hydraulic supply to the ram to allow a return spring 23 to lift the member 27 just clear of the elements 35, and then to move the anvil 37 to a second position with a flat surface thereon under the staples. The hydraulic pressure is then re-applied to compress the limbs of the elements 35 to the belt 15. Hydraulic pressure is supplied to the ram through lines 46, 48 from a hand pump 7 having a pressure release valve 79 which is opened at the end of a working cycle to allow the spring 23 to fully retract the ram 20. The valve 47 comprises a spindle 49, carrying the lever 57 and urged to a rest position by a spring 58, passing through a fixed sleeve 52 into which open the hydraulic lines 46, 48 to be connected by an annular groove 56 in the spindle. A slot 71 in the spindle connects the groove 56 to a relief line 69 when the lever 57 is in its position for momentary relief of hydraulic pressure. An arm 62, rotatable on the spindle 49 and urged against a peg 64 in the spindle by a spring 65, engages the anvil 37 so that when the lever 57 is moved beyond the pressure relief position the arm 62 is caused to move the anvil to its second position. The joining elements 35 are held by a rod 34 in a fixed locating comb 33. The block 31 is hung from the member 27 and is pivoted to facilitate the loading of staples into the slot 41, and is locked in its working position by camactuated spring-released bolts 81 (Fig. 12, not shown). In modifications, the valve 79 is omitted, full pressure release being by holding the lever 57 in its position to vent the line 48 into the line 69, and a slotted link and cam arrangement is used to move the anvil.

Title: Mast assemblies for material handling vehicles
IPC: B66F9/08
Filed: 1973-09-25
Abstract: 1434210 Masts RAYMOND CORP 25 Sept 1973 [2 Jan 1973] 44815/73 Heading B8H The mast assembly of a material handling vehicle comprises upper and lower mast sections 14, 18, a lifting carriage 17 being movable along the mast section 14 and upon which is located a laterally movable load platform (not shown) which is movable to either side of the mast assembly, the assembly being such that lateral bending moments which are set up on extension of the load platform to either side of the mast assembly are significantly reduced as compared with those set up in a prior-art type device. The lifting carriage 17 is provided with four rollers which run along the mast members 14a, 14b of the mast section 14, the latter in turn being guided on the lower mast section 18 by means of rollers 19a-19d, and a cable 28 extends from an attachment point 29 on the member 18a of mast section 18 over pulleys 21, 23 on mast section 14 to an attachment point 17h on the carriage 17, while a second cable 25 extends from mast member 18b of mast section 18 over pulleys 24, 22 on mast section 14 to an attachment point 17g on the carriage 17 while a ram 10, 11 is connected to a bracket on the mast section 14 for raising and lowering the said section 14 and thus the raising and lowering of the carriage 17. When a load W L  is moved through a distance X a moment of magnitude W L X is applied to the carriage 17 and the rollers between the carriage 17 and the mast section 14 apply a clockwise bending moment to the mast section 14 which is resisted by an equal moment of magnitude RL, and the mast section 14 in turn applies a clockwise bending moment to the lower mast section 18 which will be opposed by a moment Py equal to the moment W L X, P and R being the respective roller forces. It is stated that due to the cable arrangements described the moments RL and Py are considerably reduced as compared to those generated in a prior-art type device. In Fig. 5a (not shown), the moments Rh and Py are plotted against the carriage displacement distance both for a prior-art type mast and for the mast described above. In a modification, Fig. 6 (not shown), the lower mast section (18) is itself movably guided in guide members (32a, 32b), while in Fig. 6c (not shown), a three section mast employs two serially-acting rams, while in Fig. 7 (not shown), the outer mast (14a, 14b) of the assembly shown therein is disposed outside the mast (18), and in Fig. 8 (not shown), the cables include slanting sources, but in all the modified arrangements of mast assemblies described the cable arrangements are the same as those described in relation to Fig. 2 above.

Title: Improvements in the control of the Switching of a Gate Controlled Rectifier Device
IPC: H02M1/08
Filed: 1968-09-20
Abstract: 1,176,307. Triggering controlled rectifiers. HEBERLEIN & CO. A.G. 20 Sept., 1968 [20 Sept., 1967], No. 44915/68. Heading H2F. [Also in Divisions G1 and H3] In an inductive proximity switch including a gate-controlled-rectifier (e.g. thyratron, thyristor or S.C.R.) the inductive sensor directly controls the rectifier by varying the amplitude of the triggering pulse. As shown the pulse is generated by capacitor 2 discharging through the sensor inductance 6 when trigger element 4 breaks-down. The resultant pulse fires trigger 7 and hence thyristor 1, (in the absence of a metal body). The presence of metal vane 40 near the inductor 6 reduces the amplitude of the pulse below firing level. Modificadions.-(i) Resistor 13 and capacitor 12 may be provided to fire-trigger 14 late in the half cycle of the A.C. so that the supply to load is regulated to one of two levels, (and not switched off entirely by the presence of vane 40). (ii) Fig. 2 (not shown) a D.C. BIAS may be added in series with the inductive pulse by a capacitor (2<SP>1</SP>) charged from a potentiometer (9), (10) across the capacitor 2. (iii) Fig. 3, the triggers may be replaced by TRANSISTOR SWITCHES. Normally cut-off transistors 15, 16 conduct rapidly on the breakdown of Zener diode 17, and the resultant pulse from inductor 6 switches-on a normally cut-off transistor pair 20, 24. (iv) Fig. 4 illustrates a modification of Fig. 2 (not shown), using UNIJUNCTION transistors 4<SP>1</SP>, 7<SP>1</SP> as trigger elements and added D.C. bias from capacitor 2<SP>1</SP>. The circuit may be arranged to operate as shown in Fig. 5, the threshold value of unijunction 7<SP>1</SP> rising to a substantially constant value 32 (due to regulation by Zener diode 17); the D.C. bias across capacitor 2<SP>1</SP> increasing slowly as indicated by curve 33 (due to the time constant of resistors 9, 10 and capacitor 2<SP>1</SP>); and a series of pulses 34 are provided by inductor 6 due to repeated firing of unjunction 4<SP>1</SP>, whereby the triggering point, in the A.C. half cycle, of thyristor 1 varies with the position of vane 4. (v) Fig. 6 (not shown), the circuit may operate on both half-cycles of the supply by using a full-wave bridge rectifier; an A.C. load may be connected in the supply to the rectifier. (vi) Fig. 7 (not shown), the output may be connected to a pulse transformer e.g. to control a triac. (vii) Fig. 8 (not shown), the inductance 6 may be replaced by a transformer whose MUTUAL INDUCTANCE is varied by the vane 40.

(DANSK INDUSTRIE SYNDIKAT A.S.) 11 Sept 1969 [23 Sept 1968] 44996/69 Heading G1N [Also in Division G4] The flow velocity of a liquid is measured using a cylindrical probe carrying a transducer on the upstream side of its surface which responds to vortices formed in the liquid as it passes the probe, the frequency of the vortex shedding being proportional to the flow velocity. As shown in Fig.5, two transducers 22, 23 of the hot film type and connections 24, 25, 26 are provided by sputtering a film of conductive material on to the cylinder which may be glass or quartz. A covering layer of insulating material may be added by sputtering. The cylinder may be rotatably mounted in bearings 28, Fig.6, and a vane 20 provided to keep the transducer(s) about 15-30 degrees from the upstream direction. The axis of the cylinder may be inclined in the direction of flow to provide self-cleaning. Two inclined probes may be used to determine direction of flow by measuring any difference in frequency of their outputs. The vortices may be counted to give an indication of volume flowed and cost.

Abstract: 1,101,187. Shutter mechanisms. NATIONAL RESEARCH DEVELOPMENT CORPORATION. Nov. 19, 1964 [Nov. 19, 1963], No.45640/63. Heading G2A. A shutter for a rotating mirror camera (not shown) comprises an opaque disc 1 containing perforations 5, 6, 7 which co-operate with lamps 8 and photo-electric cells 9 mounted on opposite sides of the disc, which lamps and cells produce pulses which are fed to an electronic circuit which scans the monitoring pulses produced by the hundred perforations 5 and compares them with a series of monitoring pulses produced by a photo-cell, a lamp and the mirror so that when these two sets of pulses have the same frequency for a predetermined time, a triggering pulse produced by the aperture 7 will start the event it is desired to photograph. The aperture 6 and its associated lamp and cell produce switching pulses which open a gate (11) Fig. 2 (not shown) if the two series of monitoring pulses retain the same frequency between two successive switching pulses. The mirror pulses are brought into synchronism with the monitoring pulses by manual adjustment of the air motor which drives the mirror. Various forms of disc are mentioned. A further shutter (18) may be provided to prevent multiple exposures if the event being photographed is of appreciable duration.
