Title: Improvements in and relating to calculating devices of the slide rule type
IPC: G06G1/14
Filed: 1948-05-27
Abstract: 686,161. Calculating-apparatus. CARTER, D., and PALMER, I. R. WADE-, May 27, 1948, No. 14352/48. Class 106 (i). A slide rule for calculations relating to reinforced concrete beams and floors comprises a plurality of fixed and sliding logarithmic scales for correlating beam depth, beam width, steel section, bending moment, concrete/steel stress ratio and depth of the neutral axis, and their uxtaposition is such that the correlation can be effected without more than one movement of each scale. The rule shown has fixed scales for bending moment M, steel section fe, beam depth h and depth of neutral axis x. Three slides t1, r1 and s carry similar markings of concrete/ steel stress ratio and tensile strength of steel, designed to read against respective fixed scales ; parallel longitudinal lines on the slides correspond to various tensile strengths and are intersected by curves for various stress ratios. Attached to the slide r1 is a slide b with upper and lower breadth scales for reading against the scale M and slide t1. Cursors L facilitate reading intersections on the slides. The bending moment M and beam breadth b are always predetermined and, in using the rule, the lower b scale is first adjusted against M carrying r1 with it. A datum point on the slide t1 is then set against the upper b scale and, similarly, the slide s against a selected beam depth on scale h. The stress ratio is then read off the slide r1 against the scale h. Using this stress ratio on scales t1 and s, the required steel section and depth of neutral axis are read from scales fe and x respectively. For beams where the neutral axis lies below the upper slab portion, an additional slide is employed to take into account ratios of beam to slab depth. For double reinforced beams two additional slides are used, taking account respectively of the depth ratio and section ratio of the two reinforcements. A more compact form of apparatus has slides of triangular section with the scaling distributed over the three sides covering steels in three grades according to tensile strength. Distinctive colours are used for the three grades of steel and the slides are compactly arranged in four sides of a box framework.

Title: A new curing salt
IPC: A23B4/023
Filed: 1934-05-12
Abstract: A powdery salt preparation for curing meat &c. comprises particles consisting principally, e.g. not less than 70 per cent, of sodium chloride but containing also nitrate and nitrite of sodium or potassium or the nitrate of one metal and the nitrite of the other. The nitrite and nitrate may be enclosed in the centre of the particles, and at least 90 per cent of the particles may contain the three salts.  The preparation may be obtained by spraying a concentrated solution of the salts on heated rotating rolls, e.g. at 140 DEG  C., the granular residue being removed by scraping or brushing, or falling off.  A binder, which may be a colloidal substance such as starch, gelatine, dextrin, glue, agar or tragacanth, may be added to the solution but is not essential when 80 per cent or more of sodium chloride is used.  To prevent caking, hygroscopic substances, e.g. glycerine and dextrose, especially corn sugar, may be added to the solution.  Sodium or potassium iodide may be added to medicate the preparation for goitre.  The preparation may be applied to the meats dry or used in solution and may be used with diluents, e.g. with sodium chloride or sugar, or both.  The production of a preparation for dry curing hams in 21 days at about 5 DEG  C. is described.

Title: Improvements in or relating to time switches embodying discharge tubes
IPC: H03K17/288
Filed: 1958-05-07
Abstract: 836,313. Control systems for resistance welding. PHILIPS ELECTRICAL INDUSTRIES Ltd. May 7, 1958 [May 8, 1957], No. 14615/58. Class 38 (4). [Also in Group XL (c)] A timing system comprises a gas tube fed via a resistor from a D.C. supply, a resistor connected between the cathode and the positive supply terminal, a mechanical or electronic switch between the cathode and the negative supply terminal, the control electrode being connected to a tapping across the supply; the timing being controlled by the discharge of a capacitor connected between the control electrode and cathode. In Fig. 1 the capacitor 4 is first charged via resistor 6 and part of the potentiometer 9. The timed period is initiated by closing a switch 7 which holds the tube 1 cut off until. capacitor 4 has discharged at a rate determined by the setting of the potentiometer 9. Tube 1 now conducts, providing a rapid fall of voltage between the output leads 14, 21. A discharge resistor may be connected at points 23, 24 and may be shunted by a diode to speed up the charging. In Fig. 4 (not shown), switch 7 is replaced by a further timer of the type shown in Fig. 1, so that two separate periods may be controlled by three output leads. Fig. 6 shows a part circuit of a combination of three such timers to provide control over three timed periods by leads 14, 21. A flip-flop formed by valves 30, 31 replaces the switch (equivalent to 7 of Fig. 1) of the last timer 1<SP>11</SP> and also provides re-setting of the system. Tube 30 is cut off when tube 31 is made conductive by an ignition pulse at 36. When the tube 30 is fired by a pulse at 37, tube 31 is cut off and timer 1<SP>11</SP> is started. Subsequently timers 1<SP>1</SP> and later 1 are started. When the last tube 1 fires, a pulse from the grid fires tube 31 and resets the system. If a repetitive operation is required, a time delay 41 is included so that the sequence may be restarted a certain time after the firing of tube 1. It is stated that the system may be coupled directly or via further tubes to control alternating current by means of a main pair of gas tubes connected in parallel opposition. Power frequency pulses from a saturated transformer may be injected into the system to provide synchronized operation. Resistance welding control.-The above-described system shown in Fig. 6 provides control of the duration of electrode pressure, welding current, and after pressure.

Title: Improvements in or relating to bolt or like welding tools
IPC: B23K9/20
Filed: 1949-06-02
Abstract: 659,162. Electric welding. GUSTAFSON, W., and ALLMANNA SVENSKA ELEKTRISKA AKTIEBOLAGET. June 2, 1949, No. 14817. [Class 83 (iv)] A compressed air operated bolt welding tool having three support legs 20, and in which the bolt is moved away from the structure for initiating a welding arc, is characterized by two interengaging pistons 4, 6, the piston 6 being integral with the bolt clamp 7, adjustment of the pistons being accomplished by enclosing oil in a chamber 17 between the pistons so that they form a rigid unit, the length of which is shorter than the distance between the structure and an adjustable stop means by an amount equal to the welding arc gap. Compressed air enters the tool through channel 1 and moves a transverse piston 10 against a spring 23 so that a cam 19 on a cover 12 attached to piston 4 is depressed against the action of a spring 18 by being forced out of a groove 9 in the piston 10. The air also flows through channels 2 and 3 and pushes piston 6 against the shoulder 6a. Piston 4 after its initial movement due to cam 19 is prevented from moving further by the spring 18. The air also enters channels 11 and operates a valve pin 13 which opens a ball valve 15 so that chamber 17 fills with oil from chamber 16. With a bolt inserted in the clamp 7 and the tool in position the compressed air supply is cut off and the channel 1 connected to atmosphere by operating means 21. The ball valve 15 retains the oil in chamber 17 so forming an incompressible junction between the bolt and the cam 19. The piston 10 returns to its initial position and a spring 24 forces the cam 19 into the groove 9 of the piston 10 so that the bolt is moved away from the structure a distance equal to the depth of the groove 9 and an arc is now initiated. The groove 9 can be arranged eccentric so that by rotating the piston 10 the arc-forming movement of the bolt can be adjusted. The compressed air is allowed to re-enter the channel 1 whereupon the bolt is pressed against the structure and fused in position.
