Abstract: The present invention relates to a method of making a solid cleaning composition. The method can include pressing and/or vibrating a flowable solid of a self-solidifying cleaning composition. For a self-solidifying cleaning composition, pressing and/or vibrating a flowable solid determines the shape and density of the solid but is not required for forming a solid. The method can employ a concrete block machine for pressing and/or vibrating. The present invention also relates to a solid cleaning composition made by the method and to solid cleaning compositions including particles bound together by a binding agent.

Abstract: A tubular pen for recording apparatus and the like has a freely displaceable weight within a hollow body and there is a cap or protective element on the end of the body. The cap and the weight are connected together by a spring of metal or synthetic resin material such that there is relative movement between the cap and weight and the interconnected cap and weight together with the spring constitute a single assembly. The spring has its ends firmly attached to the cap and weight or may be integral with these two components.
