Filed: 1968-05-14
Abstract: 1,187,558. Mechanical interrupters. CANDY MFG. CO. Inc. 14 May, 1968 [28 Sept., 1967], No. 22952/68. Heading H1N. [Also in Division F2] A device for operating a control member such as the microswitch 14, for example, at an adjustable point in the cycle of a mechanical drive coupled to an input shaft 33, and for varying the duration of the operated conditionboth of which adjustments may be preset or varied while the device is running-comprises an elongated helical gear 53 meshing with a helical gear 58 to revolve an elongated cam 13 via spur gears 60 and 75. Helical gear 58 and the cam 13 are axially movable on respective square-section shafts 34 and 36 carrying the spur gears 60 and 75. The cam 13 has a circumferential triangular rise portion 84 with an axial edge 83 and a spiral edge 82 such that the peripheral extent of the rise engaging a follower roller 95 as the cam rotates depends upon the axial position of the cam, which is selectable by manual rotation of shaft 37 by knob 94. Shaft 37 threadedly drives a member 88 having an arm 89 carrying a pointer (90, Fig. 2, not shown) which indicates percentage " ON " time on a scale (25) on top plate 21, a second arm on member 88 simultaneously moving the cam 13 along its shaft 36. Manual rotation of the knob 68 similarly drives member 69 and moves gear 58 along its shaft 34. As gear 58 moves axially it is forced to rotate shaft 34 relative to the shaft 33 and hence turns the cam 13 an amount indicated by an arm 70 on a scale (24, Fig. 2, not shown) on top plate 21 as degrees of phase position of the instant of switching with respect to the drive cycle. Two or more control devices may be driven in tandem (Fig. 7, not shown).

Abstract: 147,373. Chapman, L. Sept. 19, 1919 Lubricant conveyed by fluid.-A solid lubricant such as powdered graphite or mica is conveyed from a lubricator into steam-pipes of engines or steam spaces of boilers by condensed water. The lubricant is contained in a vessel T. Fig. 1, surrounded by a condensing-jacket J formed with heat-radiating wings W. Steam enters the jacket by way of a pipe SW, valve SV, sight chamber SF and passages SC<1>, SC<3>, and condensed water enters the vessel T through holes P made adjustable.by screwing the vessel T up or down in the jacket, or by non-adjustable holes P<0> A conical base D spreads the powder towards the sides of the vessel, and the water and powder escape through adjustable notches N into a funnel FL communicating by a passage D<2> with the sight chamber, whence the mixture drains into the steam pipe &c. The top of the vessel T is closed by a cap K raised and lowered by a screw S<2> in a bridge piece engaging the top of the jacket by means of flanges and capable of being swung aside on a vertical point PV, Fig. 8. after the cap K is raised. Water condensed on the underside of the cap collects in a gutter G and passes to the jacket J through a helical groove HG formed through the screw threads around the vessel T. The passages SC<1>, SC<3> are provided with an inspection cap IC. To enable the lubricator to be fixed to steam pipes running in various directions, a pad P<*>, curved to fit against. the pipe, is secured to an oblique face P' on a bracket BR which can be turned into different angular positions with respect to a junction piece JP. The bracket is fixed to the pipe by straps passed through holes H, and the pipe SW projects into the steam pipe. Fig. 8 shows a modification in which the condensing-chamber has an overflow nozzle Z by which surplus water drains back to the sight chamber, limiting the quantity which enters the vessel T. The holes P are replaced by saw cuts P<9> the edges of which are inclined upwards to prevent lubricant from entering the jacket. The holes P and P‹, Fig. 1, may be inclined for the same purpose.

Title: Improvements in devices for automatically regulating the tension of alternating currents
IPC: G05F3/06
Filed: 1931-08-17
Abstract: 389,811. Automatic regulation. ELECTRO-CONSTRUCTIONS SOC. ANON., Rue Schertz, Metzgerau, Strasbourg, Bas Rhin, France. Aug. 17, 1931, No. 23158. Convention date, Aug. 18, 1930. [Class 38 (iv).] Constant voltage is obtained from a source of varying A.C. by means of an automatic regulator which consists of a condenser C and choke I working at saturation connected in series and in parallel with the primary of a transformer T across the supply E the secondary of the transformer being connected in series opposition to the choke to balance out small variations of voltage in it. The constant voltage is obtained across the choke and secondary winding. The core section of the choke is reduced to cause early saturation. This restriction of section may be produced by building the core of laminations in which alternate ones have air gaps. To improve the power factor of the system the transformer T may be constructed to have a low inductive power factor at all loads. Specifications 255, 688, [Class 38 (ii), Electric currents, Converting &c.], and 336,716, [Class 38 (iv), Electric supply and transmission systems &c.], are referred to.

Title: Safety device for trip dog actuated needle mechanisms in hay balers
IPC: A01F15/08
Filed: 1960-07-04
Abstract: 890,982. Baling-machines. WILLIAMSON, G. A. July 4, 1960, No. 23231/60. Class 94(1). The invention relates to a safety device for hay baling machines of the kind in which hay is compressed in a bale chamber by a plunger and in which needles move across the path of the plunger in a tying operation. In such machines, the needles and the tying mechanism can be actuated when a circular member 8 is clutched into a driven relationship with a rotating clutch housing 1. Such clutching is normally performed when a hay metering device depresses a lever 13 and permits a trip dog 4 to be released from a position in which it holds a spring biased roller 3 away from the path of an internal clutch or driving lug 2 in the rotating clutch housing 1. When this occurs, the driving lug 2 on the rotating clutch housing 1 engages the roller 3 and causes the circular member 8 to rotate with the clutch housing. The release of the trip dog 4 at an instant when the lug 2 is in close proximity to the roller 3 can result in the roller 3 bouncing off the lug 2, after having initiated actuation of the needles, and it is then necessary for the rotating clutch housing 1 to perform another revolution before positive drive-connection is made between the lug 2 and the roller 3 to operate the tying mechanism, during which time a plunger stop dog may come into action with the resultant shearing of the conventional safety shear bolt in the flywheel of the drive source. To prevent this occurrence an external cam is mounted on the periphery of the rotating clutch housing, this cam co-operating with means preventing the trip dog 4 from being released except when the roller 3 and the lug 2 are in a predetermined position. As shown an additional pivoted lever 22 is provided, this lever having latch means 24 that holds the trip dog 4 against release, independently of the lever 13, until it is depressed by a cam 21 on the rotating clutch housing. Alternatively, the cam 21 could be so profiled that it operates the pivoted lever 22 such that it holds the latch means 24 away from the trip dog except during the danger period.

Title: Road simulation system
IPC: G09B9/04
Filed: 1959-07-07
Abstract: 882,380. Programmed electric control systems; electric measuring systems. ESSO RESEARCH & ENGINEERING CO. July 7, 1959 [July 16, 1958], No. 23284/59. Classes 38 (6) and 40 (1). [Also in Group XIX] In order to simulate a road test on a motor vehicle which is provided with automatic transmission, the stationary vehicle is mounted so that the rear wheels drive both a centrifugal blower and an hydraulic pump; the accelerator pedal position of the vehicle and the loading of the hydraulic pump being controlled automatically by signals recorded on a magnetic tape made during a genuine road test and representing the accelerator pedal portions and brake pedal actuation respectively. Recording.-The accelerator pedal 20 of the car which is genuinely road tested is linked to both the normal throttle 48 and to the slider of a variable resistor 54 in series with the collector of a transistor audio oscillator so as to vary the output frequency. The variable frequency signal is recorded on a magnetic tape at 68. Also recorded is the output of a fixed-frequency oscillator 62 which is energized by a switch 60 each time the brake pedal 58 is actuated. Play-back.-The car which is to be artificially road tested is mounted so that its rear wheels drive a drum 78, Fig. 9. The drum 78 drives both a centrifugal blower 112 to simulate air resistance to a moving car, and an hydraulic pump 102 which circulates oil through a cooler 134 via pneumatically operated valves 128, 130. When the valves are open, the pump 102 presents only a slight load, but when the valves 128, 130 are closed in sequence, the load simulates the use of the car brakes. The magnetic tape, recorded as above, is played at 142. The braking signal, selected by a narrow band-pass filter 148, actuates the valves 128, 130 through an electropneumatic relay 160. The variablefrequency accelerator pedal position signal is converted at 150 to a variable-amplitude signal which controls a reversible D.C. motor with positional follow-up, Fig. 11 (not shown). The motor rotates a toothed sector which rocks the accelerator pedal through an adjustable linkage, Fig. 12 (not shown).
