Title: Improvements in and connected with plumb rules and like devices
IPC: G01C9/12
Filed: 1925-01-05
Abstract: 244,922. Ovenden, J. F., and Thompson, F. Jan. 5, 1925. Plumb-rules.-In a plumb-rule of the kind in which a pivoted weight operates a pointer, the indicating-means is contained in a casing which is removably mounted in a recess in a rule or straight edge. In the form shown the casing consists of an oval front plate a and two semicircular rear plates b, c connected to the plate a by screws surrounded by distance-pieces e. The plate b is marked with graduations f which are visible through a windom w in the plate a. The weight k is mounted on a pivot pin h bearing in the plates a, c and carries a pointer g moving over the scale f. The casing is removably secured to the rule l by screws m. The weight and pointer unit may be formed as indicated in Fig. 4 by providing the pointer with two holes, the upper of which receives the pin h. The weight, consisting of lead, is cast around the lower end of the pointer and part of it enters the lower hole to form a key x. In a modification the weight and pointer are mounted on separate pivots and are connected together by a pin and slot, so that the upper end of the pointer receives a magnified movement.

Title: Improvements in or relating to rolling mills
Inventor: DRESCHSLER GOTTFRIED
IPC: B21B37/62
Filed: 1961-01-04
Abstract: 975,091. Hydraulically-loaded rollers. ERSTE MASCHINENFABRIK KARLMARX-STADT VEB. Jan. 4, 1961, No. 291/61. Heading F1P. A control system for uniformly operating hydraulic pistons in a rolling mill, such as calenders for finishing fabrics, comprises two working cylinders 1, 2 each having a piston 3, 4, one cylinder 2 being directly connected to a low-pressure pump 5 and the other 1 to a high-pressure pump 6 which is supplied with hydraulic fluid from the low-pressure pump, and a magnetically-controlled piston valve 12 for establishing communication between the two working cylinders and the high pressure pump. When a predetermined working pressure has been reached the output from the pump 5 passes to branch lines 10, 11 leading to the pump 6, which is of the variable stroke radial piston type, and to the valve 12 and cylinder 2, respectively. The piston pump is adjusted so that, at maximum stroke, it accepts exactly half of the output of the pump 5 and directs it through a reversing valve 16 to the cylinder 1 and the pistons move the roller towards and into engagement with a fixed roller. The pressure in the system is indicated on a manometer 30 and when it reaches, say, 10 atmospheres, the manometer operates the valve 12 so that the supply from the piston pump 6 is directed to both cylinders. As the pressure rises to, say, 25 atmospheres, the delivery from the pump is reduced to maintain the pressure at that level. The movement of the pistons is reversed by operation of the valve 16 and excess pressure in the system is relieved by valves 22, 23.

Title: Crane
IPC: B66C23/36
Filed: 1963-01-04
Abstract: 1,005,004. Mobile self-erecting tower cranes. KOEHRING CO. Jan. 4, 1963 [July 20, 1962], No. 521/63. Heading B8B. A mobile self-erecting tower crane 1, Fig. 1, which slews on a turntable 8 and luffs about a pivot 23 has cables 232, 234, Fig. 18, connected between the tower and the jib to prevent the jib swinging backwards over-centre. The two pairs of cables are held spaced from the jib and tower by struts 238 and are pulled together to prevent fouling when the jib is lowered by springs 239, Fig. 21. When the boom 15, Fig. 1, is lowered to a folded position, parallel and adjacent to the tower boom 17, it is locked thereto by a hook 250, Fig. 26, carried on the tower boom and raised to release the boom 15 by a cable 259 operated from the driver's cab. A stabilizer mast 18 holds the tower in a vertical position and can be released by withdrawing pins to permit lowering of the tower. The stabilizer mast 18 comprises two struts 45, 46, Fig. 3, and may be raised and lowered by the hoist line 55, Fig. 2 in conjunction with a sling 57, Fig. 4. This sling is attached to a frame 64 pivoted to the bottom of the stabilizer 18. When the tower and jib have been lowered, the pins are removed to allow the frame 64 to slide along the tower to a lowered position, shown in full lines on Fig. 2, in which position they may be locked. The stabilizer is raised by pulling on the sling 57 with the hoist line. The crane is erected by the reeving system shown schematically in Fig. 10, which comprises hoisting cables 110, 111 and upper and lower sheave assemblies 31, 116 (see also Fig. 2). This arrangement incorporates a safe load indicator device as described in Specification 1,005,003. To raise the crane cable 111 is wound up on drums 121, 122 causing the sheave assembly 116 to be pulled upwards taking up the slack in cable 110. When the tower has been locked in a vertical position the cable 110 is wound on to drum 112 thereby pulling the sheave 116 downwards to unwind cable 111 from drums 121, 122. Thus the same length of cable can be used again to raise the jib to its working position. Economies are thus effected in drum size and length of cable required. Specifications 1,005,006, 1,005,007, and 1,005,008 also are referred to.

Filed: 1967-01-05
Abstract: 1,142,751. Automatic frequency control systems. GENERAL ELECTRIC CO. Ltd. 3 Jan., 1968 [5 Jan., 1967], No. 696/67. Heading H3A. A frequency synthesizer comprising a variable frequency oscillator 4, Fig. 1, synchronized to a selected harmonic of a reference frequency by a variable divider 10 and comparator 3, is characterized by the provision of an interpolation circuit 31 adapted to vary the division ratio of divider 10 periodically by one step thereby adjusting the frequency of oscillator 4 between harmonics. The control switch 36 which brings in the interpolation circuit simultaneously locks the coarse control 5 of the oscillator frequency, and increases the time constant of the filter 12, e.g. from 0À1 to 1 second. In the system shown the reference frequency supplied to the comparator from the crystal oscillator 1 and divider 2 is 1 kc./s., and the interpolation circuit comprises a low frequency oscillator (32, Fig. 2, not shown) manually adjustable from 0 to 1000 cycles/ second and feeding two bi-stable circuits (34, 35) in series, these being re-set by reset pulses from the counter forming the divider 10. The second bi-stable (35) alters by one digit the re-setting count of the counter, and if the frequency of the low frequency oscillator is m cycles/second does this m times per second, i.e. m times in each 1000 counting cycles. The frequency of oscillator 4 is therefore stabilized at n+m/1000 kc./s., where n is the division ratio of divider 10.

Title: Immunoassay
Inventor: YAMAZAKI MASAHIKO
IPC: G01N33/531
Filed: 1991-01-08
Abstract: PURPOSE:To stop immunoreaction without changing a specific signal by adding a substance only bonded to one of an antibody of a free state and an immobilized antibody to allow the activity of the bonded antibody to disappear. CONSTITUTION:B/F separation (separation of an antigen-antibody reaction product and a non-reaction product) becomes inaccurate because of the irregularity of a time in non-uniform immunoassay used in such a case that an objective substance in immunoassay is a polymer. At this time, the substance only bonded to one of an antibody of a free state and an immobilized antibody by a sandwich reaction method and allowing the activity of the bonded antibody to disappear is added. Only one antibody is bonded by the addition of said substance before the separation of the reaction product bonded to an insolubilized carrier and a non-reaction product after immunoreaction and the activity thereof is allowed to disappear to stop immunoreaction and, thereafter, the operation of B/F separation is performed. Finally, the label bonded to the insolubilized carrier is measured and the antigen in a sample can be accurately analyzed regardless of the operation time of B/F separation.
